+description: Ultracite Rules - AI-Ready Formatter and Linter
+globs: "**/*.{ts,tsx,js,jsx}"
+alwaysApply: true
+---
+
+# Project Context
+Ultracite enforces strict type safety, accessibility standards, and consistent code quality for JavaScript/TypeScript projects using Biome's lightning-fast formatter and linter.
+
+## Key Principles
+- Zero configuration required
+- Subsecond performance
+- Maximum type safety
+- AI-friendly code generation
+
+## Before Writing Code
+1. Analyze existing patterns in the codebase
+2. Consider edge cases and error scenarios
+3. Follow the rules below strictly
+4. Validate accessibility requirements
+
+## Rules
+
+### Accessibility (a11y)
+- Don't use `accessKey` attribute on any HTML element.
+- Don't set `aria-hidden="true"` on focusable elements.
+- Don't add ARIA roles, states, and properties to elements that don't support them.
+- Don't use distracting elements like `<marquee>` or `<blink>`.
+- Only use the `scope` prop on `<th>` elements.
+- Don't assign non-interactive ARIA roles to interactive HTML elements.
+- Make sure label elements have text content and are associated with an input.
+- Don't assign interactive ARIA roles to non-interactive HTML elements.
+- Don't assign `tabIndex` to non-interactive HTML elements.
+- Don't use positive integers for `tabIndex` property.
+- Don't include "image", "picture", or "photo" in img alt prop.
+- Don't use explicit role property that's the same as the implicit/default role.
+- Make static elements with click handlers use a valid role attribute.
+- Always include a `title` element for SVG elements.
+- Give all elements requiring alt text meaningful information for screen readers.
+- Make sure anchors have content that's accessible to screen readers.
+- Assign `tabIndex` to non-interactive HTML elements with `aria-activedescendant`.
+- Include all required ARIA attributes for elements with ARIA roles.
+- Make sure ARIA properties are valid for the element's supported roles.
+- Always include a `type` attribute for button elements.
+- Make elements with interactive roles and handlers focusable.
+- Give heading elements content that's accessible to screen readers (not hidden with `aria-hidden`).
+- Always include a `lang` attribute on the html element.
+- Always include a `title` attribute for iframe elements.
+- Accompany `onClick` with at least one of: `onKeyUp`, `onKeyDown`, or `onKeyPress`.
+- Accompany `onMouseOver`/`onMouseOut` with `onFocus`/`onBlur`.
+- Include caption tracks for audio and video elements.
+- Use semantic elements instead of role attributes in JSX.
+- Make sure all anchors are valid and navigable.
+- Ensure all ARIA properties (`aria-*`) are valid.
+- Use valid, non-abstract ARIA roles for elements with ARIA roles.
+- Use valid ARIA state and property values.
+- Use valid values for the `autocomplete` attribute on input elements.
+- Use correct ISO language/country codes for the `lang` attribute.
+
+### Code Complexity and Quality
+- Don't use consecutive spaces in regular expression literals.
+- Don't use the `arguments` object.
+- Don't use primitive type aliases or misleading types.
+- Don't use the comma operator.
+- Don't use empty type parameters in type aliases and interfaces.
+- Don't write functions that exceed a given Cognitive Complexity score.
+- Don't nest describe() blocks too deeply in test files.
+- Don't use unnecessary boolean casts.
+- Don't use unnecessary callbacks with flatMap.
+- Use for...of statements instead of Array.forEach.
+- Don't create classes that only have static members (like a static namespace).
+- Don't use this and super in static contexts.
+- Don't use unnecessary catch clauses.
+- Don't use unnecessary constructors.
+- Don't use unnecessary continue statements.
+- Don't export empty modules that don't change anything.
+- Don't use unnecessary escape sequences in regular expression literals.
+- Don't use unnecessary fragments.
+- Don't use unnecessary labels.
+- Don't use unnecessary nested block statements.
+- Don't rename imports, exports, and destructured assignments to the same name.
+- Don't use unnecessary string or template literal concatenation.
+- Don't use String.raw in template literals when there are no escape sequences.
+- Don't use useless case statements in switch statements.
+- Don't use ternary operators when simpler alternatives exist.
+- Don't use useless `this` aliasing.
+- Don't use any or unknown as type constraints.
+- Don't initialize variables to undefined.
+- Don't use the void operators (they're not familiar).
+- Use arrow functions instead of function expressions.
+- Use Date.now() to get milliseconds since the Unix Epoch.
+- Use .flatMap() instead of map().flat() when possible.
+- Use literal property access instead of computed property access.
+- Don't use parseInt() or Number.parseInt() when binary, octal, or hexadecimal literals work.
+- Use concise optional chaining instead of chained logical expressions.
+- Use regular expression literals instead of the RegExp constructor when possible.
+- Don't use number literal object member names that aren't base 10 or use underscore separators.
+- Remove redundant terms from logical expressions.
+- Use while loops instead of for loops when you don't need initializer and update expressions.
+- Don't pass children as props.
+- Don't reassign const variables.
+- Don't use constant expressions in conditions.
+- Don't use `Math.min` and `Math.max` to clamp values when the result is constant.
+- Don't return a value from a constructor.
+- Don't use empty character classes in regular expression literals.
+- Don't use empty destructuring patterns.
+- Don't call global object properties as functions.
+- Don't declare functions and vars that are accessible outside their block.
+- Make sure builtins are correctly instantiated.
+- Don't use super() incorrectly inside classes. Also check that super() is called in classes that extend other constructors.
+- Don't use variables and function parameters before they're declared.
+- Don't use 8 and 9 escape sequences in string literals.
+- Don't use literal numbers that lose precision.
+
+### React and JSX Best Practices
+- Don't use the return value of React.render.
+- Make sure all dependencies are correctly specified in React hooks.

+- Don't insert comments as text nodes.
+- Don't assign JSX properties multiple times.
+- Don't add extra closing tags for components without children.
+- Use `<>...</>` instead of `<Fragment>...</Fragment>`.
+- Watch out for possible "wrong" semicolons inside JSX elements.
+
+### Correctness and Safety
+- Don't assign a value to itself.
+- Don't return a value from a setter.
+- Don't compare expressions that modify string case with non-compliant values.
+- Don't use lexical declarations in switch clauses.

+- Don't have unused labels.
+- Don't have unused private class members.
+- Don't have unused variables.
+- Make sure void (self-closing) elements don't have children.
+- Don't return a value from a function with the return type 'void'
+- Use isNaN() when checking for NaN.
+- Make sure "for" loop update clauses move the counter in the right direction.
+- Make sure typeof expressions are compared to valid values.
+- Make sure generator functions contain yield.
+- Don't use await inside loops.
+- Don't use bitwise operators.

+- Don't use unnecessary escapes in string literals.
+- Don't use useless undefined.
+- Make sure getters and setters for the same property are next to each other in class and object definitions.
+- Make sure object literals are declared consistently (defaults to explicit definitions).
+- Use static Response methods instead of new Response() constructor when possible.
+- Make sure switch-case statements are exhaustive.
+- Make sure the `preconnect` attribute is used when using Google Fonts.
+- Use `Array#{indexOf,lastIndexOf}()` instead of `Array#{findIndex,findLastIndex}()` when looking for the index of an item.

+- Don't use callbacks in asynchronous tests and hooks.
+- Don't use negation in `if` statements that have `else` clauses.
+- Don't use nested ternary expressions.
+- Don't reassign function parameters.
+- This rule lets you specify global variable names you don't want to use in your application.

+- Use Number.isFinite instead of global isFinite.
+- Use Number.isNaN instead of global isNaN.
+- Don't assign to imported bindings.
+- Don't use irregular whitespace characters.
+- Don't use labels that share a name with a variable.
+- Don't use characters made with multiple code points in character class syntax.
+- Make sure to use new and constructor properly.
+- Don't use shorthand assign when the variable appears on both sides.
+- Don't use octal escape sequences in string literals.
+- Don't use Object.prototype builtins directly.
+- Don't redeclare variables, functions, classes, and types in the same scope.
+- Don't have redundant "use strict".
+- Don't compare things where both sides are exactly the same.
+- Don't let identifiers shadow restricted names.
+- Don't use sparse arrays (arrays with holes).
+- Don't use template literal placeholder syntax in regular strings.

+
+### Next.js Specific Rules
+- Don't use `<img>` elements in Next.js projects.
+- Don't use `<head>` elements in Next.js projects.
+- Don't import next/document outside of pages/_document.jsx in Next.js projects.
+- Don't use the next/head module in pages/_document.js on Next.js projects.
+
+### Testing Best Practices
+- Don't use export or module.exports in test files.
+- Don't use focused tests.
+- Make sure the assertion function, like expect, is placed inside an it() function call.
+- Don't use disabled tests.
+
+## Common Tasks
+- `npx ultracite init` - Initialize Ultracite in your project
+- `npx ultracite fix` - Format and fix code automatically
+- `npx ultracite check` - Check for issues without fixing
+
+## Example: Error Handling
+```typescript
+// ✅ Good: Comprehensive error handling
+try {
+  const result = await fetchData();
+  return { success: true, data: result };
+} catch (error) {
+  console.error('API call failed:', error);
+  return { success: false, error: error.message };
+}
+
+// ❌ Bad: Swallowing errors
+try {
+  return await fetchData();
+} catch (e) {
+  console.log(e);
+}
+```

+### ✅ 端口访问测试
+
+#### 1. 本地访问测试
+- **localhost:3001**: ✅ 可访问
+- **127.0.0.1:3001**: ✅ 可访问
+- **响应**: 返回 `/api/auth/guest` 重定向（正常）
+
+#### 2. 内网IP访问测试
+- **192.168.150.22:3001**: ✅ 可访问
+- **响应**: 返回 `/api/auth/guest` 重定向（正常）
+
+### ✅ 防火墙状态
+- **firewalld**: 未运行或未安装
+- **ufw**: 未运行或未安装
+- **iptables**: 
+  - 未找到针对 3001 端口的特殊规则
+  - INPUT 链默认策略：允许（未限制）
+
+### ✅ 端口开放结论
+
+**3001 端口已完全开放，可以从以下方式访问：**
+
+1. **本地访问**
+   - `http://localhost:3001`
+   - `http://127.0.0.1:3001`
+
+2. **内网访问**
+   - `http://192.168.150.22:3001`
+
+3. **通过FRPC穿透访问**
+   - `http://156.225.27.52:5245` (通过FRPC TCP穿透)
+
+## 详细检查信息
+
+### 端口监听详情
+```
+LISTEN 0  511  *:3001  *:*  users:(("next-server (v1",pid=3704508,fd=19))
+```
+
+**说明**:
+- `*:3001`: 监听所有网络接口的 3001 端口
+- 这意味着可以从内网、外网（如果防火墙允许）访问
+
+### 防火墙检查
+
+#### iptables 规则
+- 未找到针对 3001 端口的特殊限制规则
+- INPUT 链默认允许所有连接
+
+#### 防火墙服务
+- 未发现运行中的防火墙服务（firewalld/ufw）
+- 系统可能使用默认的 iptables 规则，且未限制 3001 端口
+
+## 安全建议
+
+### 当前状态
+✅ **端口已开放**: 3001 端口可以从内网访问
+
+### 建议配置
+
+如果需要限制访问，可以考虑：
+
+1. **仅允许内网访问**（推荐）
+   ```bash
+   # 允许内网访问
+   iptables -A INPUT -p tcp --dport 3001 -s 192.168.150.0/24 -j ACCEPT
+   # 拒绝其他访问
+   iptables -A INPUT -p tcp --dport 3001 -j DROP
+   ```
+
+2. **使用防火墙服务管理**
+   ```bash
+   # 如果使用 firewalld
+   firewall-cmd --permanent --add-port=3001/tcp
+   firewall-cmd --reload
+   ```
+
+3. **通过FRPC访问（当前方案）**
+   - 应用监听在 127.0.0.1:3001（仅本地）
+   - 通过 FRPC 穿透到外网端口 5245
+   - 这样更安全，不需要直接开放 3001 端口到外网
+
+## 当前配置分析
+
+### FRPC 配置
+```ini
+[ai-chatbot]
+name = ai-chatbot
+type = tcp
+local_ip = 127.0.0.1
+local_port = 3001
+remote_port = 5245
+```
+
+**说明**:
+- FRPC 配置使用 `127.0.0.1:3001`（本地回环）
+- 但实际上应用监听在 `*:3001`（所有接口）
+- 这没有问题，FRPC 可以从本地回环访问应用
+
+### 建议优化
+
+如果希望更安全，可以：
+
+1. **修改应用监听地址**
+   - 让应用只监听 `127.0.0.1:3001`
+   - 这样只能从本地访问，更安全
+
+2. **保持当前配置**
+   - 当前配置允许内网访问，方便调试和管理
+   - 通过 FRPC 提供外网访问
+
+## 总结
+
+✅ **3001 端口完全开放**
+- 可以从本地访问
+- 可以从内网访问（192.168.150.22:3001）
+- 可以通过 FRPC 穿透访问（156.225.27.52:5245）
+
+✅ **应用正常运行**
+- PM2 管理，状态正常
+- 响应正常，返回预期的重定向
+
+✅ **防火墙未限制**
+- 未发现运行中的防火墙服务
+- iptables 未限制 3001 端口
+
+---
+
+**检查命令**:
+```bash
+# 检查端口监听
+ss -tlnp | grep ':3001'
+
+# 测试访问
+curl http://192.168.150.22:3001
+
+# 检查防火墙
+iptables -L INPUT -n
+```

+2. 如果没有配置，则显示预定义的静态模型
+3. 优先显示标记为"默认"的模型
+
+**调用流程**:
+- 前端组件：`components/model-selector.tsx`
+- 调用 API：`/api/models` 获取可用模型列表
+- 支持视觉模型标签显示
+- 支持默认模型标签显示
+
+## 数据库结构
+
+### AiProvider 表
+```sql
+CREATE TABLE "AiProvider" (
+  id uuid PRIMARY KEY,
+  name varchar(128) NOT NULL,           -- 提供商名称
+  type varchar NOT NULL,                -- 类型: alibaba, openai, custom
+  baseUrl text NOT NULL,                -- API 基础 URL
+  apiKey text NOT NULL,                 -- API Key
+  isEnabled boolean DEFAULT true,       -- 是否启用
+  createdAt timestamp DEFAULT now(),
+  updatedAt timestamp DEFAULT now(),
+  updatedBy uuid REFERENCES "User"(id)
+);
+```
+
+### AiModel 表
+```sql
+CREATE TABLE "AiModel" (
+  id uuid PRIMARY KEY,
+  providerId uuid NOT NULL REFERENCES "AiProvider"(id) ON DELETE CASCADE,
+  modelId varchar(128) NOT NULL,        -- 模型 ID
+  displayName varchar(128) NOT NULL,    -- 显示名称

+  isDefault boolean DEFAULT false,
+  isEnabled boolean DEFAULT true,
+  createdAt timestamp DEFAULT now(),
+  updatedAt timestamp DEFAULT now(),
+  updatedBy uuid REFERENCES "User"(id)
+);
+```
+
+## 配置优先级
+
+### AI 模型使用顺序
+1. **数据库配置优先** - 从 AiModel 表动态加载
+2. **环境变量回退** - 使用 DASHSCOPE_API_KEY 等
+3. **预定义模型** - 最后使用预定义的模型列表
+
+### 存储服务优先级
+1. **数据库配置** - 优先使用标记为默认的存储配置
+2. **环境变量** - 使用 S3_* 系列环境变量
+3. **Vercel Blob** - 最后回退到 Vercel Blob
+
+## 实现示例
+
+### 配置阿里云通义千问
+
+1. **创建提供商**
+   ```
+   名称: 阿里云通义千问
+   类型: Alibaba
+   API 地址: https://dashscope.aliyuncs.com/compatible-mode/v1
+   API Key: sk-xxxxxxxxxxxxxxxxxxxxxxxx
+   ```
+
+2. **创建模型**
+   ```
+   提供商: 阿里云通义千问
+   模型 ID: qwen-turbo
+   显示名称: 通义千问 Turbo
+   支持图片输入: ☑
+   设为默认: ☑
+   ```
+
+### 配置 S3 存储
+
+```
+配置名称: 阿里云 OSS
+类型: S3 兼容存储
+端点: https://oss-cn-hangzhou.aliyuncs.com
+区域: cn-hangzhou
+存储桶: my-chatbot-bucket
+Access Key ID: LTAI5t...
+Secret Access Key: xxxxxxxxxxxxxxxx
+公开访问 URL 前缀: https://my-chatbot-bucket.oss-cn-hangzhou.aliyuncs.com
+设为默认: ☑
+```
+
+## 关键代码位置
+
+### 后端核心文件
+- `lib/db/schema.ts` - 数据库表定义
+- `lib/db/queries.ts` - 数据库查询函数
+- `lib/ai/dynamic-provider.ts` - 动态模型加载
+- `app/(admin)/api/ai-providers/route.ts` - 提供商 API
+- `app/(admin)/api/ai-models/route.ts` - 模型 API
+- `app/(admin)/api/storage/route.ts` - 存储 API
+- `app/(chat)/api/models/route.ts` - 前端模型列表 API
+
+### 前端核心文件
+- `components/model-selector.tsx` - 模型选择组件
+- `app/(admin)/settings/admin-settings-client.tsx` - 管理设置页面
+- `app/(chat)/api/files/upload/route.ts` - 文件上传处理
+
+## 环境变量（可选）
+
+虽然不再需要配置这些，但如果设置了环境变量，系统会作为回退使用：
+
+```env
+# AI 配置回退
+DASHSCOPE_API_KEY=your_key
+DASHSCOPE_BASE_URL=https://dashscope.aliyuncs.com/compatible-mode/v1
+
+# S3 存储回退
+S3_ENDPOINT=https://s3.amazonaws.com
+S3_REGION=us-east-1
+S3_BUCKET=my-bucket
+S3_ACCESS_KEY_ID=your_access_key
+S3_SECRET_ACCESS_KEY=your_secret_key
+S3_PUBLIC_URL=https://my-bucket.s3.amazonaws.com
+```
+
+## 故障排除
+
+### 模型不显示
+- 检查 AiProvider 是否启用 (isEnabled = true)
+- 检查 AiModel 是否启用 (isEnabled = true)
+- 检查 API 密钥和地址是否正确
+- 查看浏览器开发者工具中 `/api/models` 的响应
+
+### 文件上传失败
+- 确认 StorageConfig 已设置为默认 (isDefault = true)
+- 验证 S3 凭证和端点
+- 检查存储桶权限设置
+
+### 默认模型不生效
+- 确保只有一个模型设置为默认 (isDefault = true)
+- 重启应用使缓存更新
+- 检查前端是否正确读取 defaultModelId
+
+## 安全考虑
+
+- **API Key 保护** - API Key 在数据库中存储，不在响应中回显
+- **权限控制** - 所有管理 API 需要 admin 权限
+- **数据加密** - 建议在生产环境中加密存储的敏感信息
+- **访问控制** - 限制对 `/admin/settings` 的访问
+
+## 迁移说明
+
+如果从旧版本升级：
+1. 运行数据库迁移：`npm run db:migrate`
+2. 访问管理设置重新配置 AI 模型和存储
+3. 删除 `.env.local` 中的旧配置（可选）
+4. 重启应用

+
+## API 请求格式详解
+
+所有供应商都遵循 OpenAI Chat Completions API 规范：
+
+### 基本请求结构
+
+```typescript
+interface ChatCompletionRequest {
+  model: string;              // 模型 ID
+  messages: Message[];        // 消息列表
+  temperature?: number;       // 0-2，控制随机性
+  max_tokens?: number;        // 最大生成 token 数
+  stream?: boolean;           // 是否流式响应
+  top_p?: number;            // 核采样参数
+  frequency_penalty?: number; // 频率惩罚
+  presence_penalty?: number;  // 存在惩罚
+  stop?: string | string[];   // 停止序列
+}
+
+interface Message {
+  role: "system" | "user" | "assistant" | "tool";
+  content: string | ContentPart[];
+  name?: string;
+  tool_calls?: ToolCall[];
+}
+```
+
+### 多模态输入（支持的模型）
+
+```json
+{
+  "model": "qwen-vl-plus",
+  "messages": [
+    {
+      "role": "user",
+      "content": [
+        {
+          "type": "text",
+          "text": "这张图片里有什么？"
+        },
+        {
+          "type": "image_url",
+          "image_url": {
+            "url": "https://example.com/image.jpg"
+          }
+        }
+      ]
+    }
+  ]
+}
+```
+
+### Function Calling
+
+```json
+{
+  "model": "qwen-plus",
+  "messages": [
+    {
+      "role": "user",
+      "content": "波士顿今天的天气怎么样？"
+    }
+  ],
+  "tools": [
+    {
+      "type": "function",
+      "function": {
+        "name": "get_current_weather",
+        "description": "获取指定位置的当前天气",
+        "parameters": {
+          "type": "object",
+          "properties": {
+            "location": {
+              "type": "string",
+              "description": "城市和州，例如 San Francisco, CA"
+            }
+          },
+          "required": ["location"]
+        }
+      }
+    }
+  ],
+  "tool_choice": "auto"
+}
+```
+
+---
+
+## 常见问题
+
+### Q: 配置后前端没有显示新模型？
+
+**A:** 请检查：
+1. 模型是否启用（`isEnabled = true`）
+2. 供应商是否启用（`isEnabled = true`）
+3. 清除浏览器缓存和 Cookie
+4. 硬刷新页面（Ctrl+Shift+R / Cmd+Shift+R）
+
+### Q: 模型请求失败，返回 503 错误？
+
+**A:** 可能原因：
+1. API Key 无效或过期
+2. Base URL 配置错误
+3. 供应商服务不可用
+4. 网络连接问题
+
+**调试步骤：**
+1. 检查服务器日志：`pm2 logs ai-chatbot`
+2. 使用 curl 测试 API：
+   ```bash
+   curl -X POST <baseUrl>/chat/completions \
+     -H "Authorization: Bearer <apiKey>" \
+     -H "Content-Type: application/json" \
+     -d '{"model":"<model>","messages":[{"role":"user","content":"test"}]}'
+   ```
+
+### Q: 阿里云模型和 OpenAI 模型有什么区别？
+
+**A:**
+- **API 格式：** 完全相同（OpenAI 兼容）
+- **模型 ID：** 不同（qwen-plus vs gpt-4）
+- **Base URL：** 不同（dashscope.aliyuncs.com vs api.openai.com）
+- **功能支持：** 基本相同，部分高级功能可能有差异
+
+### Q: 如何配置本地部署的模型？
+
+**A:** 选择 **custom** 类型，配置：
+```json
+{
+  "type": "custom",
+  "baseUrl": "http://localhost:8000/v1",
+  "apiKey": "your-local-key"
+}
+```
+
+确保本地服务提供 OpenAI 兼容的 API 接口。

+## 技术实现说明
+
+### 代码位置
+
+- **动态 Provider：** `lib/ai/dynamic-provider.ts`
+- **数据库 Schema：** `lib/db/schema.ts`
+- **API 路由：** `app/api/admin/ai-providers/route.ts`、`app/api/admin/ai-models/route.ts`
+- **前端组件：** `components/model-selector.tsx`、`components/multimodal-input.tsx`
+
+### Provider 创建逻辑
+
+```typescript
+function getOrCreateProvider(provider: AiProvider) {
+  switch (provider.type) {
+    case "alibaba":
+      return createOpenAI({
+        apiKey: provider.apiKey,
+        baseURL: provider.baseUrl, // https://dashscope.aliyuncs.com/compatible-mode/v1
+      });
+    
+    case "openai":
+      return createOpenAI({
+        apiKey: provider.apiKey,
+        baseURL: provider.baseUrl || "https://api.openai.com/v1",
+      });
+    
+    case "custom":
+    default:
+      return createOpenAI({
+        apiKey: provider.apiKey,
+        baseURL: provider.baseUrl, // 任何 OpenAI 兼容的 URL
+      });
+  }
+}
+```
+
+### 缓存机制
+
+系统使用 `Map` 缓存已创建的 provider 实例，避免重复创建：
+
+```typescript
+const providerCache = new Map<string, ReturnType<typeof createOpenAI>>();
+```
+
+缓存键格式：`${providerId}-${baseUrl}`
+
+---
+
+## 最佳实践
+
+1. **分类管理：** 为不同用途的模型创建不同的供应商配置（如"快速对话"、"深度思考"）
+2. **设置默认：** 为最常用的模型设置 `isDefault = true`
+3. **排序优化：** 使用 `sortOrder` 控制前端显示顺序
+4. **描述清晰：** 为每个模型添加清晰的描述，帮助用户选择
+5. **定期更新：** 供应商可能推出新模型，及时更新配置
+6. **监控使用：** 查看日志了解各模型的使用情况和错误率
+
+---
+
+## 安全建议
+
+1. **API Key 保护：**
+   - 不要在前端代码中暴露 API Key
+   - API Key 存储在数据库中（建议加密）
+   - 定期轮换 API Key
+
+2. **访问控制：**
+   - 只有管理员可以配置供应商和模型
+   - 使用 `requireAdmin()` 中间件保护 API 端点
+
+3. **费用控制：**
+   - 设置合理的 `max_tokens` 限制
+   - 监控 API 使用量
+   - 考虑实现用户级别的配额限制
+
+---
+
+## 更新日志
+
+- **2025-12-05：** 实现多供应商独立配置，支持阿里云、OpenAI、OpenAI兼容
+- **未来计划：** 支持更多供应商类型（Claude、Gemini等）

+# FRPC 修复完成报告
+
+## 问题总结
+
+### 原始问题
+1. 访问 `http://156.225.27.52:5245/` 时端口号消失，返回 Nginx 404
+2. FRPC 服务无法启动，一直处于重启循环
+
+### 根本原因
+1. **FRPC 配置错误**: `ai-chatbot` 配置使用了 HTTP 类型，但缺少 `custom_domains`
+2. **其他代理配置错误**: 多个 HTTP 类型的代理（`http044`, `bt-panel` 等）缺少必需的 `custom_domains` 或 `subdomain` 配置
+3. **配置冲突**: HTTP 类型配置不完整导致 FRPC 无法启动
+
+## 修复方案
+
+### 1. 将所有 HTTP 类型改为 TCP 类型
+- HTTP 类型需要配置 `custom_domains` 或 `subdomain`，配置复杂
+- TCP 类型更简单直接，适合端口转发场景
+- 将所有代理配置统一改为 TCP 类型
+
+### 2. 修复后的配置
+
+```ini
+[ai-chatbot]
+name = ai-chatbot
+type = tcp
+local_ip = 127.0.0.1
+local_port = 3001
+remote_port = 5245
+```
+
+### 3. 修复的其他代理
+- `http044`: SSH (5204) - 改为 TCP
+- `bt-panel`: 宝塔面板 (5205) - 改为 TCP
+- `ai-classification`: AI分类系统 (5206) - 改为 TCP
+- `performance-api`: 性能API (5234) - 改为 TCP
+- `qwen-api`: Qwen API (5236) - 改为 TCP
+- `weipinghui-parser`: 微品汇解析器 (5238) - 改为 TCP
+- `shebeiguanli-frontend`: 设备管理前端 (5243) - 改为 TCP
+- `shebeiguanli-backend`: 设备管理后端 (5244) - 改为 TCP
+
+## 修复结果
+
+### ✅ FRPC 服务状态
+- **状态**: `active (running)`
+- **启动时间**: 2025-12-04 14:05:50
+- **所有代理**: 全部启动成功
+
+### ✅ ai-chatbot 代理状态
+- **代理名称**: `ai-chatbot`
+- **状态**: `start proxy success`
+- **本地地址**: `127.0.0.1:3001`
+- **远程端口**: `5245`
+
+### ✅ 访问测试
+- **访问地址**: `http://156.225.27.52:5245`
+- **连接状态**: ✅ 成功连接
+- **响应**: HTTP 307 重定向到 `/api/auth/guest`
+- **说明**: 应用正常工作，返回了预期的认证重定向
+
+## 当前状态
+
+### 应用访问
+- **外网访问**: `http://156.225.27.52:5245`
+- **内网访问**: `http://192.168.150.22:3001`
+- **状态**: ✅ 正常运行
+
+### FRPC 服务
+- **服务状态**: ✅ 运行中
+- **配置文件**: `/etc/frp/frpc.ini`
+- **备份文件**: `/etc/frp/frpc.ini.backup.before_fix`
+
+### 应用服务
+- **PM2 状态**: ✅ 运行中
+- **进程名称**: `ai-chatbot`
+- **监听端口**: `3001`
+
+## 注意事项
+
+### 1. 重定向 URL 问题
+应用返回的重定向 URL 中包含 `localhost:3001`，这可能导致浏览器访问时出现问题。建议：
+- 检查应用的重定向逻辑，确保使用正确的域名和端口
+- 或者在应用配置中设置正确的 `NEXT_PUBLIC_BASE_URL`
+
+### 2. 端口冲突
+`shebeiguanli-backend` 和 `ai-chatbot` 都使用 3001 端口，但：
+- `shebeiguanli-backend` 使用内网 IP `192.168.150.22:3001`
+- `ai-chatbot` 使用本地回环 `127.0.0.1:3001`
+- 目前没有冲突，但需要注意
+
+### 3. 配置备份
+- 原始配置已备份到: `/etc/frp/frpc.ini.backup.before_fix`
+- 如需恢复，可以使用备份文件
+
+## 验证命令
+
+### 检查 FRPC 状态
+```bash
+ssh root@192.168.150.22
+systemctl status frpc.service
+```
+
+### 查看 FRPC 日志
+```bash
+journalctl -u frpc.service -n 50 | grep ai-chatbot
+```
+
+### 测试本地应用
+```bash
+curl http://localhost:3001
+```
+
+### 测试外网访问
+```bash
+curl http://156.225.27.52:5245
+```
+
+## 后续优化建议
+
+1. **应用配置优化**
+   - 设置正确的 `NEXT_PUBLIC_BASE_URL` 环境变量
+   - 修复重定向 URL 中的 localhost 问题
+
+2. **监控和日志**
+   - 设置 FRPC 日志轮转
+   - 添加应用健康检查
+
+3. **安全性**
+   - 考虑添加访问控制
+   - 配置 HTTPS（如果需要）
+
+## 总结
+
+✅ **问题已解决**: FRPC 服务正常运行，ai-chatbot 代理成功启动  
+✅ **访问正常**: 外网可以通过 `http://156.225.27.52:5245` 访问应用  
+✅ **配置已优化**: 所有代理配置统一使用 TCP 类型，更稳定可靠
+

+# FRPC 访问问题说明
+
+## 问题描述
+
+访问 `http://156.225.27.52:5245/` 时：
+- 浏览器地址栏变成 `156.225.27.52`（端口号消失）
+- 返回 404 Not Found（Nginx）
+
+## 问题分析
+
+### 可能的原因
+
+1. **FRPC 配置类型问题**
+   - 之前将配置改为 HTTP 类型，但 HTTP 类型需要通过 FRPS 的 HTTP 端口访问
+   - TCP 类型更适合直接端口访问
+
+2. **Nginx 拦截请求**
+   - Nginx 的 `default_server` 可能拦截了未匹配的请求
+   - 5245 端口应该由 FRPS 监听，而不是 Nginx
+
+3. **FRPS 服务端配置**
+   - FRPS 可能没有正确配置 5245 端口的 TCP 穿透
+   - 需要检查 FRPS 服务端的配置
+
+4. **浏览器行为**
+   - 某些浏览器在遇到重定向时会去掉端口号
+   - 需要确保应用正确处理端口
+
+## 解决方案
+
+### 方案 1: 使用 TCP 类型（推荐）
+
+TCP 类型穿透更简单直接，适合直接端口访问：
+
+```ini
+[ai-chatbot]
+name = ai-chatbot
+type = tcp
+local_ip = 127.0.0.1
+local_port = 3001
+remote_port = 5245
+```
+
+**访问方式**: `http://156.225.27.52:5245/`
+
+### 方案 2: 使用 HTTP 类型（需要 FRPS 支持）
+
+如果使用 HTTP 类型，需要：
+1. FRPS 配置 HTTP 端口（通常是 80 或 8080）
+2. 通过 FRPS 的 HTTP 端口 + custom_domains 访问
+3. 配置示例：
+
+```ini
+[ai-chatbot]
+name = ai-chatbot
+type = http
+local_ip = 127.0.0.1
+local_port = 3001
+custom_domains = 156.225.27.52
+```
+
+**访问方式**: `http://156.225.27.52:FRPS_HTTP_PORT/`（不是 5245）
+
+### 方案 3: 使用 Nginx 反向代理
+
+如果 FRPS 不支持 HTTP 类型，可以：
+1. 保持 FRPC 使用 TCP 类型
+2. 配置 Nginx 反向代理到本地 3001 端口
+3. 通过 Nginx 的 80 端口访问
+
+## 修复步骤
+
+### 自动修复
+
+运行修复脚本：
+
+```bash
+./fix-frpc-access.sh
+```
+
+### 手动修复
+
+1. **SSH 连接到服务器**
+   ```bash
+   ssh -p 5204 root@156.225.27.52
+   ```
+
+2. **检查 FRPC 配置**
+   ```bash
+   cat /etc/frp/frpc.ini | grep -A 6 'ai-chatbot'
+   ```
+
+3. **修复配置（使用 TCP 类型）**
+   ```bash
+   # 备份配置
+   cp /etc/frp/frpc.ini /etc/frp/frpc.ini.backup
+   
+   # 删除旧的 ai-chatbot 配置
+   sed -i '/\[ai-chatbot\]/,+6d' /etc/frp/frpc.ini
+   
+   # 添加正确的 TCP 配置
+   cat >> /etc/frp/frpc.ini << 'EOF'
+   
+   [ai-chatbot]
+   name = ai-chatbot
+   type = tcp
+   local_ip = 127.0.0.1
+   local_port = 3001
+   remote_port = 5245
+   EOF
+   ```
+
+4. **重启 FRPC 服务**
+   ```bash
+   systemctl restart frpc.service
+   ```
+
+5. **检查服务状态**
+   ```bash
+   systemctl status frpc.service
+   journalctl -u frpc.service -n 50 | grep ai-chatbot
+   ```
+
+6. **测试本地应用**
+   ```bash
+   curl http://localhost:3001
+   ```
+
+## 检查清单
+
+- [ ] FRPC 服务运行正常
+- [ ] FRPC 配置使用 TCP 类型
+- [ ] 应用运行在 3001 端口
+- [ ] FRPS 服务端配置了 5245 端口
+- [ ] 防火墙开放了 5245 端口
+- [ ] 本地应用可以访问（curl http://localhost:3001）
+
+## 常见问题
+
+### Q: 为什么访问时端口号会消失？
+
+A: 这可能是浏览器的行为，或者应用返回了重定向。检查应用的重定向逻辑，确保保留端口号。
+
+### Q: 为什么返回 Nginx 404？
+
+A: 说明请求被 Nginx 拦截了。检查：
+1. FRPS 是否正确监听 5245 端口
+2. Nginx 是否配置了 default_server 拦截所有请求
+3. FRPC 配置是否正确
+
+### Q: TCP 和 HTTP 类型有什么区别？
+
+A:
+- **TCP**: 直接端口转发，访问时使用 `http://IP:PORT`
+- **HTTP**: 通过 FRPS 的 HTTP 端口访问，需要配置 custom_domains
+
+### Q: 如何确认 FRPS 配置？
+
+A: FRPS 配置通常在 FRP 服务端服务器上，需要检查：
+1. FRPS 配置文件中的 `allow_ports` 是否包含 5245
+2. FRPS 服务是否正常运行
+3. FRPS 日志中是否有 ai-chatbot 的连接记录
+
+## 下一步
+
+1. 运行修复脚本或手动修复配置
+2. 确认 FRPS 服务端配置正确
+3. 测试访问 `http://156.225.27.52:5245/`
+4. 如果仍有问题，检查 FRPS 服务端配置

+
+## Features
+
+- [Next.js](https://nextjs.org) App Router
+  - Advanced routing for seamless navigation and performance
+  - React Server Components (RSCs) and Server Actions for server-side rendering and increased performance
+- [AI SDK](https://ai-sdk.dev/docs/introduction)
+  - Unified API for generating text, structured objects, and tool calls with LLMs
+  - Hooks for building dynamic chat and generative user interfaces
+  - Supports xAI (default), OpenAI, Fireworks, and other model providers
+- [shadcn/ui](https://ui.shadcn.com)
+  - Styling with [Tailwind CSS](https://tailwindcss.com)
+  - Component primitives from [Radix UI](https://radix-ui.com) for accessibility and flexibility
+- Data Persistence
+  - [Neon Serverless Postgres](https://vercel.com/marketplace/neon) for saving chat history and user data
+  - [Vercel Blob](https://vercel.com/storage/blob) for efficient file storage
+- [Auth.js](https://authjs.dev)
+  - Simple and secure authentication
+
+## Model Providers
+
+This template uses the [Vercel AI Gateway](https://vercel.com/docs/ai-gateway) to access multiple AI models through a unified interface. The default configuration includes [xAI](https://x.ai) models (`grok-2-vision-1212`, `grok-3-mini`) routed through the gateway.
+
+### AI Gateway Authentication
+
+**For Vercel deployments**: Authentication is handled automatically via OIDC tokens.
+
+**For non-Vercel deployments**: You need to provide an AI Gateway API key by setting the `AI_GATEWAY_API_KEY` environment variable in your `.env.local` file.
+
+With the [AI SDK](https://ai-sdk.dev/docs/introduction), you can also switch to direct LLM providers like [OpenAI](https://openai.com), [Anthropic](https://anthropic.com), [Cohere](https://cohere.com/), and [many more](https://ai-sdk.dev/providers/ai-sdk-providers) with just a few lines of code.
+
+## Deploy Your Own
+
+You can deploy your own version of the Next.js AI Chatbot to Vercel with one click:
+
+[![Deploy with Vercel](https://vercel.com/button)](https://vercel.com/templates/next.js/nextjs-ai-chatbot)
+
+## Running locally
+
+You will need to use the environment variables [defined in `.env.example`](.env.example) to run Next.js AI Chatbot. It's recommended you use [Vercel Environment Variables](https://vercel.com/docs/projects/environment-variables) for this, but a `.env` file is all that is necessary.
+
+> Note: You should not commit your `.env` file or it will expose secrets that will allow others to control access to your various AI and authentication provider accounts.
+
+1. Install Vercel CLI: `npm i -g vercel`
+2. Link local instance with Vercel and GitHub accounts (creates `.vercel` directory): `vercel link`
+3. Download your environment variables: `vercel env pull`
+
+```bash
+pnpm install
+pnpm db:migrate # Setup database or apply latest database changes
+pnpm dev
+```
+
+Your app template should now be running on [localhost:3000](http://localhost:3000).

+# DreamOmni2 服务器部署指南
+
+## 📋 服务器信息
+- **IP**: 156.225.27.52
+- **端口**: 5204
+- **用户**: root
+- **密码**: Jsjj@8888
+
+## 🚀 快速部署步骤
+
+### 步骤 1: SSH 连接到服务器
+
+```bash
+ssh -p 5204 root@156.225.27.52
+```
+
+输入密码: `Jsjj@8888`
+
+### 步骤 2: 上传部署脚本
+
+**方法一: 使用 SCP 上传**
+
+在你的本地电脑终端执行：
+
+```bash
+scp -P 5204 dreamomni2-deploy.sh root@156.225.27.52:~/
+```
+
+**方法二: 直接在服务器创建**
+
+SSH连接后，在服务器上执行：
+
+```bash
+cat > dreamomni2-deploy.sh << 'EOF'
+# 这里粘贴 dreamomni2-deploy.sh 的完整内容
+EOF
+
+chmod +x dreamomni2-deploy.sh
+```
+
+### 步骤 3: 执行部署脚本
+
+```bash
+bash dreamomni2-deploy.sh
+```
+
+脚本会自动完成以下任务：
+1. ✅ 检查系统信息和GPU
+2. ✅ 安装系统依赖
+3. ✅ 安装 Miniconda
+4. ✅ 创建独立的 Python 虚拟环境
+5. ✅ 安装 PyTorch (自动检测CUDA版本)
+6. ✅ 克隆 DreamOmni2 仓库
+7. ✅ 安装所有依赖包
+8. ✅ 下载模型权重
+
+## 📦 手动部署步骤 (如果脚本出现问题)
+
+### 1. 连接服务器并更新系统
+
+```bash
+ssh -p 5204 root@156.225.27.52
+apt update && apt upgrade -y
+apt install -y git wget build-essential
+```
+
+### 2. 检查 GPU
+
+```bash
+nvidia-smi
+```
+
+### 3. 安装 Miniconda
+
+```bash
+wget https://repo.anaconda.com/miniconda/Miniconda3-latest-Linux-x86_64.sh
+bash Miniconda3-latest-Linux-x86_64.sh -b -p $HOME/miniconda3
+export PATH="$HOME/miniconda3/bin:$PATH"
+conda init bash
+source ~/.bashrc
+```
+
+### 4. 创建虚拟环境
+
+```bash
+conda create -n dreamomni2 python=3.10 -y
+conda activate dreamomni2
+```
+
+### 5. 安装 PyTorch (根据CUDA版本)
+
+**CUDA 12.x:**
+```bash
+pip install torch torchvision torchaudio --index-url https://download.pytorch.org/whl/cu121
+```
+
+**CUDA 11.8:**
+```bash
+pip install torch torchvision torchaudio --index-url https://download.pytorch.org/whl/cu118
+```
+
+### 6. 克隆 DreamOmni2
+
+```bash
+cd ~
+git clone https://github.com/dvlab-research/DreamOmni2.git
+cd DreamOmni2
+```
+
+### 7. 安装依赖
+
+```bash
+pip install -r requirements.txt
+pip install transformers diffusers accelerate safetensors huggingface_hub
+```
+
+### 8. 下载模型
+
+```bash
+mkdir -p models
+cd models
+pip install -U huggingface_hub
+huggingface-cli download xiabs/DreamOmni2 --local-dir ./dreamomni2-model
+```
+
+## 🎯 使用 DreamOmni2
+
+### 激活环境
+
+```bash
+conda activate dreamomni2
+cd ~/DreamOmni2
+```
+
+### 运行推理示例
+
+```bash
+python inference.py \
+  --source_image ./examples/source.jpg \
+  --reference_image ./examples/reference.jpg \
+  --prompt "将源图像的风格改为参考图像的风格" \
+  --output ./output.jpg
+```
+
+### 创建简单测试脚本
+
+```python
+# test_dreamomni2.py
+import torch
+from PIL import Image
+
+def test_model():
+    print("正在测试 DreamOmni2...")
+    print(f"PyTorch 版本: {torch.__version__}")
+    print(f"CUDA 可用: {torch.cuda.is_available()}")
+    if torch.cuda.is_available():
+        print(f"GPU 数量: {torch.cuda.device_count()}")
+        print(f"GPU 名称: {torch.cuda.get_device_name(0)}")
+    
+    # 这里添加 DreamOmni2 的实际推理代码
+    print("✅ 环境测试通过！")
+
+if __name__ == "__main__":
+    test_model()
+```
+
+运行测试：
+```bash
+python test_dreamomni2.py
+```
+
+## 🔧 常见问题
+
+### Q1: 如何检查部署状态？
+
+```bash
+conda activate dreamomni2
+python -c "import torch; print(f'PyTorch: {torch.__version__}, CUDA: {torch.cuda.is_available()}')"
+```
+
+### Q2: 如何查看显存使用情况？
+
+```bash
+watch -n 1 nvidia-smi
+```
+
+### Q3: 模型下载太慢怎么办？
+
+可以使用国内镜像或者手动下载：
+
+```bash
+export HF_ENDPOINT=https://hf-mirror.com
+huggingface-cli download xiabs/DreamOmni2 --local-dir ./models/dreamomni2-model
+```
+
+### Q4: 如何配置 API 服务？
+
+创建 API 服务脚本：
+
+```python
+# api_server.py
+from fastapi import FastAPI, File, UploadFile
+from fastapi.responses import FileResponse
+import uvicorn
+
+app = FastAPI()
+
+@app.post("/generate")
+async def generate_image(
+    source: UploadFile = File(...),
+    reference: UploadFile = File(...),
+    prompt: str = ""
+):
+    # 这里添加 DreamOmni2 推理逻辑
+    return {"status": "success"}
+
+if __name__ == "__main__":
+    uvicorn.run(app, host="0.0.0.0", port=8000)
+```
+
+安装依赖并运行：
+```bash
+pip install fastapi uvicorn python-multipart
+python api_server.py
+```
+
+## 💾 硬件要求
+
+- **推荐**: NVIDIA RTX 3090 / 4090 或更高
+- **最低显存**: 16GB VRAM
+- **系统内存**: 32GB+ RAM
+- **存储空间**: 50GB+ (模型 + 依赖)
+
+## 🔐 安全建议
+
+1. **修改SSH密码**:
+```bash
+passwd
+```
+
+2. **配置防火墙**:
+```bash
+ufw allow 5204
+ufw enable
+```
+
+3. **禁用root远程登录** (可选，但推荐):
+```bash
+# 创建新用户
+adduser aiuser
+usermod -aG sudo aiuser
+# 修改 /etc/ssh/sshd_config
+# PermitRootLogin no
+```

+cd ~/DreamOmni2
+python -c "import torch; print('✅ PyTorch安装成功')"
+python -c "from transformers import AutoModel; print('✅ Transformers安装成功')"
+python -c "from diffusers import StableDiffusionPipeline; print('✅ Diffusers安装成功')"
+
+# 查看模型文件
+ls -lh ~/DreamOmni2/models/dreamomni2-model/
+```
+

+Artifacts is a special user interface mode that helps users with writing, editing, and other content creation tasks. When artifact is open, it is on the right side of the screen, while the conversation is on the left side. When creating or updating documents, changes are reflected in real-time on the artifacts and visible to the user.
+
+When asked to write code, always use artifacts. When writing code, specify the language in the backticks, e.g. \`\`\`python\`code here\`\`\`. The default language is Python. Other languages are not yet supported, so let the user know if they request a different language.
+
+DO NOT UPDATE DOCUMENTS IMMEDIATELY AFTER CREATING THEM. WAIT FOR USER FEEDBACK OR REQUEST TO UPDATE IT.
+
+This is a guide for using artifacts tools: \`createDocument\` and \`updateDocument\`, which render content on a artifacts beside the conversation.
+
+**When to use \`createDocument\`:**
+- ONLY when user explicitly requests to create a document, email, or code file
+- ONLY when user says "create a document", "generate a file", "make a doc", etc.
+- For complex code that needs to be saved (>50 lines)
+
+**When NOT to use \`createDocument\`:**
+- For short content or essays (<500 words) - just respond in chat
+- For conversational responses
+- For creative writing (stories, poems, essays) unless explicitly requested as a document
+- When user just asks to "write", "tell me", "explain", etc.
+- When asked to keep it in chat
+
+**Using \`updateDocument\`:**
+- Default to full document rewrites for major changes
+- Use targeted updates only for specific, isolated changes
+- Follow user instructions for which parts to modify
+
+**When NOT to use \`updateDocument\`:**
+- Immediately after creating a document
+
+Do not update document right after creating it. Wait for user feedback or request to update it.

+
+-- ==========================================
+-- 1. 更新 AI Provider 类型枚举
+-- ==========================================
+-- 注意：PostgreSQL 不支持直接修改 ENUM，需要使用 ALTER TYPE 或删除约束后重建
+-- 这里我们删除旧约束，添加新约束来支持 'volcano-video'
+
+DO $$

+# Silicon Valley: The Epicenter of Innovation
+
+## Origins and Evolution
+
+Silicon Valley, nestled in the southern part of the San Francisco Bay Area, emerged as a global technology hub in the late 20th century. Its transformation began in the 1950s when Stanford University encouraged its graduates to start their own companies nearby, leading to the formation of pioneering semiconductor firms that gave the region its name.
+
+## The Innovation Ecosystem
+
+What makes Silicon Valley unique is its perfect storm of critical elements: prestigious universities like Stanford and Berkeley, abundant venture capital, a culture that celebrates risk-taking, and a dense network of talented individuals. This ecosystem has consistently nurtured groundbreaking technologies from personal computers to social media platforms to artificial intelligence.
+
+## Challenges and Criticisms
+
+Despite its remarkable success, Silicon Valley faces significant challenges including extreme income inequality, housing affordability crises, and questions about technology's impact on society. Critics argue the region has developed a monoculture that sometimes struggles with diversity and inclusion.
+
+## Future Prospects
+
+As we move forward, Silicon Valley continues to reinvent itself. While some predict its decline due to remote work trends and competition from other tech hubs, the region's adaptability and innovative spirit suggest it will remain influential in shaping our technological future for decades to come.

+# 修复重定向端口丢失问题
+
+## 问题描述
+
+访问 `http://156.225.27.52:5245` 时：
+1. 应用返回 307 重定向到 `/api/auth/guest`
+2. 重定向后的 URL 变成 `http://156.225.27.52`（端口号丢失）
+3. 浏览器访问 80 端口，被 Nginx 拦截返回 404
+
+## 问题原因
+
+NextAuth 的 `signIn` 函数在重定向时，如果没有正确配置 `AUTH_URL` 环境变量，会使用请求的 origin，但可能会丢失端口号。
+
+## 修复方案
+
+### 方案 1: 修复代码（已实施）
+
+修改 `app/(auth)/api/auth/guest/route.ts`：
+- 确保重定向时使用正确的 base URL（包含端口）
+- 优先使用 `AUTH_URL` 环境变量
+- 如果 `AUTH_URL` 未设置，使用请求的 origin（包含端口）
+
+### 方案 2: 设置环境变量
+
+在服务器上设置环境变量：
+
+```bash
+export AUTH_URL=http://156.225.27.52:5245
+export NEXT_PUBLIC_BASE_URL=http://156.225.27.52:5245
+```
+
+或者在 `.env.local` 文件中：
+
+```bash
+AUTH_URL=http://156.225.27.52:5245
+NEXT_PUBLIC_BASE_URL=http://156.225.27.52:5245
+```
+
+## 部署步骤
+
+1. **更新代码**
+   ```bash
+   git pull  # 或上传修复后的文件
+   ```
+
+2. **设置环境变量**（如果使用方案2）
+   ```bash
+   # 编辑 .env.local
+   echo "AUTH_URL=http://156.225.27.52:5245" >> .env.local
+   echo "NEXT_PUBLIC_BASE_URL=http://156.225.27.52:5245" >> .env.local
+   ```
+
+3. **重启应用**
+   ```bash
+   pm2 restart ai-chatbot
+   # 或
+   pm2 delete ai-chatbot
+   pm2 start npm --name ai-chatbot -- start
+   ```
+
+## 验证
+
+访问 `http://156.225.27.52:5245`，应该：
+1. 正确重定向到 `/api/auth/guest`
+2. 重定向 URL 包含端口号 5245
+3. 最终能够正常访问应用
+
+## 技术细节
+
+### 修改的代码逻辑
+
+1. **获取 base URL**:
+   ```typescript
+   const baseUrl = process.env.AUTH_URL || requestUrl.origin;
+   ```
+   - 优先使用 `AUTH_URL` 环境变量
+   - 如果未设置，使用请求的 origin（包含端口）
+
+2. **处理相对路径重定向**:
+   ```typescript
+   if (redirectUrl.startsWith("/")) {
+     const baseUrl = process.env.AUTH_URL || requestUrl.origin;
+     finalRedirectUrl = new URL(redirectUrl, baseUrl).toString();
+   }
+   ```
+   - 将相对路径转换为绝对路径
+   - 确保包含正确的端口号
+
+## 注意事项
+
+1. **环境变量优先级**: `AUTH_URL` 环境变量优先于请求 origin
+2. **端口一致性**: 确保 `AUTH_URL` 中的端口与 FRPC 穿透端口一致
+3. **HTTPS**: 如果将来使用 HTTPS，需要更新 `AUTH_URL` 为 `https://`
+
+## 相关文件
+
+- `app/(auth)/api/auth/guest/route.ts` - 修复的重定向逻辑
+- `proxy.ts` - 初始重定向逻辑（已正确使用 request.url）
+- `.env.local` - 环境变量配置（可选）

+# 图片标注功能 - 前后端数据流验证
+
+## ✅ 数据格式匹配验证
+
+### 前端发送（PreviewAttachment.tsx）
+```typescript
+const response = await fetch("/api/detect-object", {
+  method: "POST",
+  headers: { "Content-Type": "application/json" },
+  body: JSON.stringify({
+    imageUrl: url,           // ✅ 来自 attachment.url (S3 URL)
+    clickX,                  // ✅ 点击位置 X 坐标
+    clickY,                  // ✅ 点击位置 Y 坐标
+    imageIndex: imageIndex || 1,  // ✅ 图片序号（从 1 开始）
+    imageWidth: img.naturalWidth,  // ✅ 图片原始宽度
+    imageHeight: img.naturalHeight // ✅ 图片原始高度
+  }),
+});
+```
+
+### 后端接收（app/main.py）
+```python
+class DetectRequest(BaseModel):
+    imageUrl: str      # ✅ 匹配
+    clickX: int        # ✅ 匹配
+    clickY: int        # ✅ 匹配
+    imageIndex: int    # ✅ 匹配
+    imageWidth: int    # ✅ 匹配
+    imageHeight: int   # ✅ 匹配
+```
+
+**结论**：✅ 字段名和类型完全匹配！
+
+---
+
+## 🔍 图片 URL 可访问性验证
+
+### 1. 前端图片来源
+用户上传的图片 → `MultimodalInput` → 上传到 S3 → 获得公开 URL → 存储在 `attachment.url`
+
+### 2. S3 URL 格式示例
+```
+https://your-bucket.s3.amazonaws.com/uploads/2025/12/xxxxx.jpg
+```
+
+### 3. 后端访问方式
+```python
+# florence_service.py line 60
+response = requests.get(image_url, timeout=10)
+image = Image.open(BytesIO(response.content)).convert("RGB")
+```
+
+**要求**：
+- ✅ S3 存储桶必须配置公开读取权限
+- ✅ URL 必须是 HTTPS（后端支持）
+- ✅ 图片格式：JPEG/PNG/WebP（PIL 支持）
+
+---
+
+## 🧪 完整测试用例
+
+### 测试 1：基本功能测试
+
+**步骤**：
+```bash
+# 1. 确认 API 服务运行正常
+ssh -p 5204 root@156.225.27.52 "curl http://localhost:8002/health"
+# 预期: {"status":"ok","model_loaded":true}
+
+# 2. 使用真实图片 URL 测试
+ssh -p 5204 root@156.225.27.52 "
+curl -X POST http://localhost:8002/api/detect-object \
+  -H 'Content-Type: application/json' \
+  -d '{
+    \"imageUrl\": \"https://images.unsplash.com/photo-1523380677598-64d85d015339\",
+    \"clickX\": 250,
+    \"clickY\": 250,
+    \"imageIndex\": 1,
+    \"imageWidth\": 500,
+    \"imageHeight\": 500
+  }'
+"
+```
+
+**预期响应**：
+```json
+{
+  "success": true,
+  "data": {
+    "description": "一个红色背包",
+    "descriptionEn": "a red backpack",
+    "confidence": 0.95,
+    "imageIndex": 1,
+    "formattedText": "📍图1: 一个红色背包"
+  },
+  "error": null
+}
+```
+
+### 测试 2：前端到后端完整流程
+
+**前端操作**：
+1. 访问 https://ai.yydd.ai
+2. 选择图片生成模型
+3. 上传一张包含明显物体的图片（如红色背包）
+4. 点击图片预览
+5. 点击"定位标注"按钮（Target 图标）
+6. 点击图片中的背包位置
+
+**预期结果**：
+- ✅ 显示 toast: "正在识别物体..."
+- ✅ 0.2-0.3 秒后显示: "识别成功：一个红色背包"
+- ✅ 输入框自动填入: "📍图1: 一个红色背包"
+- ✅ 关闭预览弹窗
+
+**验证后端日志**：
+```bash
+pm2 logs florence-api --lines 20
+```
+
+应该看到：
+```
+🔍 开始检测: http://your-s3-url/image.jpg at (250, 250)
+📥 下载图片: 1024 KB
+✂️ 裁剪区域: (150, 150, 350, 350)
+🔍 正在识别物体...
+✅ 识别结果: a red backpack
+📍 格式化输出: 📍图1: 一个红色背包
+```
+
+### 测试 3：错误处理
+
+**测试场景 A - 无效 URL**：
+```json
+{
+  "imageUrl": "https://invalid-url.com/image.jpg",
+  ...
+}
+```
+预期: `{"success": false, "error": "物体识别失败: ..."}`
+
+**测试场景 B - 网络超时**：
+前端显示: "识别失败，请检查网络连接"
+
+**测试场景 C - 图片太小**：
+点击坐标超出图片范围 → 后端自动调整裁剪区域
+
+---
+
+## 🔧 潜在问题和解决方案
+
+### 问题 1：S3 图片无法访问
+
+**症状**：
+- 后端日志: `requests.exceptions.ConnectionError`
+- 前端显示: "识别失败，请检查网络连接"
+
+**原因**：
+- S3 存储桶未配置公开读取
+- CORS 配置不正确
+- 图片 URL 已过期（如使用签名 URL）
+
+**解决**：
+```bash
+# 检查 S3 URL 是否可访问
+curl -I https://your-bucket.s3.amazonaws.com/uploads/test.jpg
+
+# 应该返回 200 OK
+```
+
+### 问题 2：CORS 错误
+
+**症状**：
+浏览器控制台: `CORS policy: No 'Access-Control-Allow-Origin' header`
+
+**原因**：
+后端 CORS 配置不包含前端域名
+
+**解决**：
+已在 `app/main.py` 中配置：
+```python
+allow_origins=["https://ai.yydd.ai", "http://localhost:3000"]
+```
+
+### 问题 3：Nginx 代理未配置
+
+**症状**：
+- 前端请求 `/api/detect-object` → 404 Not Found
+
+**原因**：
+Nginx 未将 `/api/detect-object` 代理到后端 8002 端口
+
+**解决**：
+按照《部署状态总结.md》步骤 1 配置 Nginx
+
+---
+
+## 🎯 最终验证清单
+
+部署完成后，请按顺序检查：
+
+- [ ] **后端健康检查**
+  ```bash
+  curl http://localhost:8002/health
+  # ✅ {"status":"ok","model_loaded":true}
+  ```
+
+- [ ] **Nginx 代理生效**
+  ```bash
+  curl https://ai.yydd.ai/api/detect-object -X POST \
+    -H "Content-Type: application/json" \
+    -d '{"imageUrl":"https://example.com/test.jpg","clickX":100,"clickY":100,"imageIndex":1,"imageWidth":500,"imageHeight":500}'
+  # ✅ 不应该返回 404
+  ```
+
+- [ ] **前端上传图片成功**

+   - 添加"定位标注"按钮
+   - 实现点击检测逻辑
+   - 调用后端 API
+
+2. **`components/preview-attachment.tsx`** ✅
+   - 集成标注功能
+   - 支持图片序号
+   - 显示加载状态
+
+3. **`components/multimodal-input.tsx`** ✅
+   - 接收标注结果
+   - 自动插入到输入框
+   - 显示成功提示
+
+#### 数据流
+```
+用户点击图片物体
+    ↓
+PreviewAttachment 捕获点击坐标
+    ↓
+POST /api/detect-object
+    {
+      imageUrl: "https://...",
+      clickX: 250,
+      clickY: 250,
+      imageIndex: 1,
+      imageWidth: 500,
+      imageHeight: 500
+    }
+    ↓
+Nginx 代理 → http://localhost:8002
+    ↓
+Florence-2 API 识别物体
+    ↓
+返回结果
+    {
+      success: true,
+      data: {
+        description: "红色背包",
+        formattedText: "📍图1: 红色背包"
+      }
+    }
+    ↓
+MultimodalInput 自动插入输入框
+```
+
+---
+
+## 🎯 功能验证
+
+### ✅ 问题 1：后端返回格式
+
+**确认**：后端返回的 `formattedText` 字段已经包含完整格式化文本：
+
+```json
+{
+  "formattedText": "📍图1: 红色背包"
+}
+```
+
+前端直接插入到输入框，无需额外处理。
+
+### ✅ 问题 2：Nginx 反向代理
+
+**确认**：必须配置，原因如下：
+
+1. **浏览器同源策略**：前端运行在 `https://ai.yydd.ai`，后端在 `localhost:8002`
+2. **HTTPS 要求**：浏览器不允许 HTTPS 页面访问 HTTP API
+3. **统一入口**：通过 Nginx 代理实现统一的 HTTPS 访问
+
+**已配置并测试通过** ✅

+## 🔧 实施步骤
+
+### 阶段一：后端 API 开发（第1-2天）
+
+#### 1.1 环境准备
+
+**服务器要求**：
+- CPU: 8核或以上（如果使用 GPU，CPU 要求可降低）
+- 内存: 16GB 或以上
+- GPU: NVIDIA GPU（推荐，支持 CUDA 11.8+）
+  - 显存: 4GB 或以上（推荐 8GB）
+  - 驱动: 最新版 NVIDIA 驱动
+- 存储: 10GB 可用空间
+- Python: 3.9+
+
+**安装依赖**：
+
+**步骤 1：检查 GPU 是否可用**
+```bash
+# 检查 NVIDIA 驱动
+nvidia-smi
+
+# 查看 CUDA 版本
+nvcc --version
+```
+
+**步骤 2：安装 Python 依赖**
+```bash
+# 创建 Python 虚拟环境
+cd /var/www/ai-chatbot-backend
+python3 -m venv venv
+source venv/bin/activate
+
+# 安装核心依赖
+pip install fastapi uvicorn python-multipart
+
+# 🚀 GPU 加速版本（推荐，如果有 NVIDIA GPU）
+pip install torch torchvision --index-url https://download.pytorch.org/whl/cu118
+
+# 或者使用国内镜像（更快）
+pip install torch torchvision -i https://pypi.tuna.tsinghua.edu.cn/simple
+
+# CPU 版本（如果没有 GPU）
+# pip install torch torchvision --index-url https://download.pytorch.org/whl/cpu
+
+# 其他依赖
+pip install transformers pillow requests
+pip install openai  # 用于调用翻译 API（可选）
+```
+
+**步骤 3：验证 GPU 可用性**
+```bash
+python -c "import torch; print(f'CUDA 可用: {torch.cuda.is_available()}'); print(f'GPU 数量: {torch.cuda.device_count()}'); print(f'GPU 名称: {torch.cuda.get_device_name(0) if torch.cuda.is_available() else \"N/A\"}')"
+```
+
+预期输出（如果 GPU 可用）：
+```
+CUDA 可用: True

+)
+```
+
+**方式二：手动下载（网络受限时）**
+```bash
+# 使用魔搭社区镜像（国内访问更快）
+pip install modelscope
+modelscope download --model=AI-ModelScope/Florence-2-base --local_dir ./models/florence-2
+```
+
+#### 1.3 创建 API 服务
+
+**文件结构**：
+```
+/var/www/ai-chatbot-backend/
+├── app/
+│   ├── api/
+│   │   └── detect_object.py      # 物体检测 API
+│   ├── services/

+└── start.sh                       # 启动脚本
+```
+
+**核心代码实现**（详见下文"代码实现"章节）
+
+#### 1.4 API 端点设计
+
+**POST /api/detect-object**
+
+**请求参数**：
+```typescript
+{
+  "imageUrl": string,      // 图片 URL（S3 地址）
+  "clickX": number,        // 点击 X 坐标（像素）
+  "clickY": number,        // 点击 Y 坐标（像素）
+  "imageIndex": number,    // 图片序号（从 1 开始）
+  "imageWidth": number,    // 图片原始宽度
+  "imageHeight": number    // 图片原始高度
+}
+```
+
+**响应格式**：
+```typescript
+{
+  "success": boolean,
+  "data": {
+    "description": string,     // 物体描述（中文）："绿色皮革手提包"
+    "descriptionEn": string,   // 物体描述（英文）："green leather handbag"
+    "confidence": number,      // 置信度（0-1）
+    "imageIndex": number,      // 图片序号
+    "formattedText": string    // 格式化文本："📍图1: 绿色皮革手提包"
+  },
+  "error": string | null
+}
+```
+
+**错误响应**：
+```typescript
+{
+  "success": false,
+  "data": null,
+  "error": "无法识别该区域的物体，请点击更明显的物体位置"
+}
+```
+
+---
+
+### 阶段二：前端组件开发（第3-4天）
+
+#### 2.1 修改 ImagePreview 组件
+
+**文件**：`components/image-preview.tsx`
+
+**新增功能**：
+1. 添加"定位标注"模式切换按钮
+2. 在标注模式下，鼠标悬停显示准星光标
+3. 点击时发送请求到后端 API
+4. 显示加载状态和识别结果
+5. 将结果传递给父组件
+
+**UI 设计**：
+```
+┌──────────────────────────────────────────┐
+│  ← 返回    📍 定位标注    ⬇️ 下载         │  ← 顶部工具栏
+├──────────────────────────────────────────┤
+│                                          │
+│                                          │
+│          [图片显示区域]                   │
+│      （标注模式下显示准星）                │
+│                                          │
+│                                          │
+├──────────────────────────────────────────┤
+│  识别中... 🔍                             │  ← 底部状态栏（可选）
+└──────────────────────────────────────────┘
+```
+
+#### 2.2 修改 MultimodalInput 组件
+
+**文件**：`components/multimodal-input.tsx`
+
+**新增功能**：
+1. 接收来自 `ImagePreview` 的标注结果
+2. 将标注文本插入到输入框中
+3. 使用特殊样式显示标注文本（蓝色、带图标）
+4. 支持多次标注，文本自动追加
+
+**输入框样式**：
+```
+┌──────────────────────────────────────────────────────────┐
+│  将 [📍图1: 绿色手提包] 替换成 [📍图2: 红色背包]           │
+│      ↑ 蓝色、可点击       ↑ 蓝色、可点击                  │
+└──────────────────────────────────────────────────────────┘
+```
+
+#### 2.3 创建标注文本组件
+
+**新建文件**：`components/annotation-tag.tsx`
+
+**功能**：
+- 显示标注标签（如 `📍图1: 绿色手提包`）
+- 支持点击删除
+- 特殊样式（蓝色背景、圆角、图标）
+
+**样式示例**：
+```tsx
+<span className="inline-flex items-center gap-1 px-2 py-1 bg-blue-500/10 text-blue-600 rounded-md">
+  <span>📍图1: 绿色手提包</span>
+  <button onClick={onRemove}>×</button>
+</span>
+```
+
+---
+
+### 阶段三：集成与测试（第5天）
+
+#### 3.1 本地开发测试
+
+**启动后端**：
+```bash
+cd /var/www/ai-chatbot-backend
+source venv/bin/activate
+python app/main.py
+# 访问 http://localhost:8001/docs 查看 API 文档
+```
+
+**启动前端**：
+```bash
+cd /var/www/ai-chatbot
+npm run dev
+# 访问 http://localhost:3000
+```
+
+**测试流程**：
+1. 上传测试图片（包含明显物体）
+2. 点击"定位标注"按钮
+3. 点击图片中的物体
+4. 验证识别结果是否准确
+5. 验证文本是否正确插入输入框
+
+#### 3.2 性能测试
+
+**测试指标**：
+- 单次识别耗时：< 1秒
+- 并发请求数：10 QPS
+- 内存占用：< 2GB
+
+**测试命令**：
+```bash
+# 使用 Apache Bench 测试
+ab -n 100 -c 10 -p test_data.json -T application/json \
+   http://localhost:8001/api/detect-object
+```
+
+#### 3.3 边缘情况测试
+
+**测试场景**：
+1. 点击图片空白区域（无物体）
+2. 点击模糊不清的区域
+3. 上传黑白图片
+4. 上传极小/极大图片
+5. 快速连续点击多次
+
+**预期处理**：
+- 返回友好的错误提示
+- 不崩溃、不卡死
+- 有重试机制
+
+---
+
+### 阶段四：生产部署（第6天）
+
+#### 4.1 后端部署
+
+**使用 PM2 管理进程**：
+```bash
+# 安装 PM2
+npm install -g pm2
+
+# 创建 PM2 配置文件
+cat > ecosystem.config.js << EOF
+module.exports = {
+  apps: [{
+    name: 'florence-api',
+    script: '/var/www/ai-chatbot-backend/venv/bin/python',
+    args: '/var/www/ai-chatbot-backend/app/main.py',
+    instances: 1,
+    exec_mode: 'fork',
+    max_memory_restart: '2G',
+    env: {
+      PORT: 8001,
+      MODEL_PATH: '/var/www/ai-chatbot-backend/models/florence-2'
+    }
+  }]
+}
+EOF
+
+# 启动服务
+pm2 start ecosystem.config.js
+pm2 save
+```
+
+**Nginx 反向代理**：
+```nginx
+# /etc/nginx/sites-available/ai-chatbot
+
+# 新增后端 API 代理
+location /api/detect-object {
+    proxy_pass http://127.0.0.1:8001;
+    proxy_http_version 1.1;
+    proxy_set_header Upgrade $http_upgrade;
+    proxy_set_header Connection 'upgrade';
+    proxy_set_header Host $host;
+    proxy_cache_bypass $http_upgrade;
+    
+    # 增加超时时间（因为 AI 推理需要时间）
+    proxy_connect_timeout 10s;
+    proxy_send_timeout 10s;
+    proxy_read_timeout 10s;
+}
+```
+
+#### 4.2 前端部署
+
+**构建生产版本**：
+```bash
+cd /var/www/ai-chatbot
+npm run build
+pm2 restart ai-chatbot
+```
+
+#### 4.3 监控与日志
+
+**设置日志轮转**：
+```bash
+# 查看 Florence API 日志
+pm2 logs florence-api
+
+# 设置日志文件大小限制
+pm2 install pm2-logrotate
+pm2 set pm2-logrotate:max_size 100M
+pm2 set pm2-logrotate:retain 7
+```
+
+**监控指标**：
+- API 响应时间
+- 错误率
+- 内存/CPU 使用率
+- 请求 QPS

+|------|--------|----------|
+| 单次推理时间 | < 1秒 | 使用计时器测量 |
+| 并发处理能力 | 10 QPS | Apache Bench 压测 |
+| 内存占用 | < 2GB | `top` 命令监控 |
+| 错误率 | < 1% | 压测统计 |
+
+---
+
+## 🚀 GPU 加速配置（推荐）
+
+如果您的服务器有 NVIDIA GPU，强烈建议启用 GPU 加速，可以将推理速度从 0.5-1 秒降低到 **0.1-0.3 秒**！
+
+### 1. 检查 GPU 状态
+
+```bash
+# 检查 GPU 信息
+nvidia-smi
+
+# 输出示例：
+# +-----------------------------------------------------------------------------+
+# | NVIDIA-SMI 525.125.06   Driver Version: 525.125.06   CUDA Version: 12.0     |
+# |-------------------------------+----------------------+----------------------+
+# | GPU  Name        Persistence-M| Bus-Id        Disp.A | Volatile Uncorr. ECC |
+# |   0  NVIDIA RTX 3090     Off  | 00000000:01:00.0 Off |                  N/A |
+# +-----------------------------------------------------------------------------+
+```
+
+### 2. 安装 CUDA 版本的 PyTorch
+
+```bash
+# 进入虚拟环境
+cd /var/www/ai-chatbot-backend
+source venv/bin/activate
+
+# 安装 CUDA 版本（根据您的 CUDA 版本选择）
+# CUDA 11.8
+pip install torch torchvision --index-url https://download.pytorch.org/whl/cu118
+
+# CUDA 12.1
+pip install torch torchvision --index-url https://download.pytorch.org/whl/cu121
+
+# 或使用国内镜像（更快）
+pip install torch torchvision -i https://pypi.tuna.tsinghua.edu.cn/simple
+```
+
+### 3. 验证 GPU 可用性
+
+```bash
+python << EOF
+import torch
+print(f"PyTorch 版本: {torch.__version__}")
+print(f"CUDA 可用: {torch.cuda.is_available()}")
+print(f"CUDA 版本: {torch.version.cuda}")
+print(f"GPU 数量: {torch.cuda.device_count()}")
+if torch.cuda.is_available():
+    print(f"GPU 名称: {torch.cuda.get_device_name(0)}")
+    print(f"GPU 显存: {torch.cuda.get_device_properties(0).total_memory / 1024**3:.1f} GB")
+EOF
+```
+
+### 4. 性能对比
+
+| 设备 | 推理时间 | 吞吐量 | 内存占用 |
+|------|---------|--------|---------|
+| CPU（8核） | 0.5-1秒 | 1-2 QPS | 1.5GB |
+| GPU（RTX 3090） | 0.1-0.2秒 | 5-10 QPS | 2GB（显存） |
+| GPU（T4） | 0.2-0.3秒 | 3-5 QPS | 2GB（显存） |
+| GPU（V100） | 0.15-0.25秒 | 4-7 QPS | 2GB（显存） |
+
+> 💡 **推荐配置**：RTX 3060 或以上，显存 ≥ 6GB
+
+### 5. GPU 监控
+
+```bash
+# 实时监控 GPU 使用率
+watch -n 1 nvidia-smi
+
+# 查看 GPU 进程
+nvidia-smi pmon
+
+# 记录 GPU 使用日志
+nvidia-smi dmon -s pucvmet -f gpu_usage.log
+```
+
+### 6. 故障排查
+
+#### 问题 1：`torch.cuda.is_available()` 返回 False
+
+**解决方案**：
+```bash
+# 1. 检查 NVIDIA 驱动
+nvidia-smi
+# 如果报错，需要重新安装驱动
+
+# 2. 检查 CUDA 工具包
+nvcc --version
+# 如果找不到命令，需要安装 CUDA Toolkit
+
+# 3. 重新安装 PyTorch（确保版本匹配）
+pip uninstall torch torchvision
+pip install torch torchvision --index-url https://download.pytorch.org/whl/cu118
+```
+
+#### 问题 2：显存不足（CUDA out of memory）
+
+**解决方案**：
+```python
+# 方法1: 减小批处理大小（在代码中已经是单张推理，无需调整）
+
+# 方法2: 清空 GPU 缓存
+import torch
+torch.cuda.empty_cache()
+
+# 方法3: 使用半精度推理（FP16）
+model = model.half()  # 转换为 FP16
+```
+
+#### 问题 3：推理速度慢（GPU 利用率低）
+
+**原因**：首次推理会有模型编译开销
+
+**解决方案**：
+```python
+# 在启动时预热模型
+@app.on_event("startup")
+async def warmup():
+    print("🔥 正在预热模型...")
+    dummy_image = Image.new("RGB", (224, 224), color="red")
+    await florence_service.detect_object_at_point(
+        image_url="dummy",
+        click_x=112,
+        click_y=112,
+        image_index=1,
+        image_width=224,
+        image_height=224
+    )
+    print("✅ 模型预热完成")
+```
+

+
+## ⚠️ 注意事项
+
+### 1. 模型准确度限制
+
+Florence-2 是通用视觉模型，可能存在以下情况：
+- 小物体或远景物体识别不准确
+- 罕见物体可能无法识别
+- 颜色描述可能不够精确（如"深蓝"和"浅蓝"）
+
+**解决方案**：
+- 引导用户点击明显、清晰的物体
+- 提供"重新识别"按钮
+- 允许用户手动编辑识别结果
+
+### 2. 性能优化
+
+**模型缓存**：
+- 模型加载到内存后常驻，避免重复加载
+- 使用全局单例模式
+
+**图片缓存**：
+- 对于同一张图片的多次点击，缓存下载的图片
+- 使用 LRU 缓存策略，限制内存占用
+
+**并发控制**：
+- 使用队列限制并发推理数量
+- 避免 OOM（内存溢出）
+
+### 3. 用户体验优化
+
+**加载状态**：
+- 首次使用时提示"模型加载中"
+- 识别过程中显示加载动画
+- 预估等待时间（约 0.5-1秒）
+
+**错误处理**：
+- 网络错误：提示"网络连接失败，请重试"
+- 识别失败：提示"无法识别该区域，请点击更明显的位置"
+- 服务异常：提示"服务暂时不可用，请稍后再试"

+#### 更新网站设置
+
+```typescript
+// 通过 API
+await fetch("/api/admin/settings", {
+  method: "POST",
+  headers: { "Content-Type": "application/json" },
+  body: JSON.stringify({
+    key: "siteName",
+    value: "我的 AI 聊天机器人",
+  }),
+});
+```
+
+#### 禁用工具
+
+```typescript
+// 通过 API
+await fetch("/api/admin/tools", {
+  method: "POST",
+  headers: { "Content-Type": "application/json" },
+  body: JSON.stringify({
+    toolName: "getWeather",
+    isEnabled: false,
+    description: "获取天气信息",
+  }),
+});
+```
+
+### 安全注意事项
+
+- 所有管理员 API 都使用 `requireAdmin()` 中间件保护
+- 只有管理员角色的用户才能访问系统设置页面
+- 用户删除操作需要确认，防止误操作
+- 系统设置更改会记录更新者信息

+# 快速部署指南
+
+## 快速开始（5分钟部署）
+
+### 步骤 1: 在服务器上初始化环境
+
+```bash
+# 连接到服务器
+ssh -p 5204 root@156.225.27.52
+
+# 上传并运行初始化脚本
+# (在本地执行)
+scp -P 5204 setup-server.sh root@156.225.27.52:/root/
+ssh -p 5204 root@156.225.27.52 "bash /root/setup-server.sh"
+```
+
+### 步骤 2: 配置数据库
+
+```bash
+# 在服务器上执行
+sudo -u postgres psql
+```
+
+在 PostgreSQL 中执行：
+
+```sql
+CREATE DATABASE ai_chatbot;
+CREATE USER chatbot_user WITH PASSWORD '你的安全密码';
+GRANT ALL PRIVILEGES ON DATABASE ai_chatbot TO chatbot_user;
+\q
+```
+
+### 步骤 3: 上传项目并配置
+
+```bash
+# 在本地执行
+# 1. 上传项目文件
+scp -P 5204 -r . root@156.225.27.52:/var/www/ai-chatbot/
+
+# 2. 连接到服务器
+ssh -p 5204 root@156.225.27.52
+
+# 3. 进入项目目录
+cd /var/www/ai-chatbot
+
+# 4. 创建环境变量文件
+nano .env.local
+```
+
+在 `.env.local` 中添加：
+
+```bash
+POSTGRES_URL=postgresql://chatbot_user:你的密码@localhost:5432/ai_chatbot
+AUTH_SECRET=$(openssl rand -base64 32)
+AUTH_URL=http://156.225.27.52
+```
+
+保存文件（Ctrl+X, Y, Enter）
+
+### 步骤 4: 安装和构建
+
+```bash
+# 在服务器上执行
+cd /var/www/ai-chatbot
+pnpm install
+pnpm db:migrate
+pnpm build
+```
+
+### 步骤 5: 启动应用
+
+```bash
+# 复制 PM2 配置文件
+cp ecosystem.config.js /var/www/ai-chatbot/
+
+# 启动应用
+cd /var/www/ai-chatbot
+pm2 start ecosystem.config.js
+pm2 save
+pm2 startup
+```
+
+### 步骤 6: 配置 Nginx
+
+```bash
+# 创建 Nginx 配置
+cat > /etc/nginx/sites-available/ai-chatbot << 'EOF'
+server {
+    listen 80;
+    server_name 156.225.27.52;
+
+    location / {
+        proxy_pass http://localhost:3000;
+        proxy_http_version 1.1;
+        proxy_set_header Upgrade $http_upgrade;
+        proxy_set_header Connection 'upgrade';
+        proxy_set_header Host $host;
+        proxy_set_header X-Real-IP $remote_addr;
+        proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
+        proxy_set_header X-Forwarded-Proto $scheme;
+        proxy_cache_bypass $http_upgrade;
+    }
+}
+EOF
+
+# 启用站点
+ln -s /etc/nginx/sites-available/ai-chatbot /etc/nginx/sites-enabled/
+nginx -t
+systemctl restart nginx
+```
+
+### 步骤 7: 测试
+
+访问 `http://156.225.27.52` 查看应用是否正常运行。
+
+## 使用自动部署脚本
+
+如果你想使用自动部署脚本：
+
+```bash
+# 在本地执行
+./deploy.sh
+```
+
+**注意**: 使用自动部署脚本前，需要：
+1. 在服务器上已经运行过 `setup-server.sh`
+2. 已经配置好数据库和环境变量
+3. 已经创建好 PM2 配置文件
+
+## 常见问题
+
+### 1. 连接服务器失败
+
+检查：
+- SSH 端口是否正确（5204）
+- 服务器 IP 是否正确
+- 防火墙是否允许 SSH 连接
+
+### 2. 应用无法启动
+
+检查：
+```bash
+pm2 logs ai-chatbot
+pm2 status
+```
+
+### 3. 数据库连接失败
+
+检查：
+- `.env.local` 中的 `POSTGRES_URL` 是否正确
+- PostgreSQL 服务是否运行：`systemctl status postgresql`
+- 数据库用户权限是否正确
+
+### 4. 502 Bad Gateway
+
+检查：
+- 应用是否运行：`pm2 status`
+- Nginx 配置是否正确：`nginx -t`
+- 端口 3000 是否被占用：`netstat -tulpn | grep 3000`
+
+## 更新部署
+
+```bash
+# 在服务器上执行
+cd /var/www/ai-chatbot
+git pull  # 如果使用 Git
+# 或者重新上传文件
+pnpm install
+pnpm db:migrate
+pnpm build
+pm2 restart ai-chatbot
+```
+
+## 安全建议
+
+1. **更改默认密码**：首次登录后立即更改 root 密码
+2. **使用 SSH 密钥**：配置 SSH 密钥登录，禁用密码登录
+3. **配置防火墙**：只开放必要的端口
+4. **定期更新**：`apt update && apt upgrade -y`
+5. **配置 SSL**：使用 Let's Encrypt 配置 HTTPS

+# 使用限制
+<span id="41ebef67"></span>
+## 保存时间
+任务数据（如任务状态、视频URL等）仅保留24小时，超时后会被自动清除。请您务必及时保存生成的视频。 
+<span id="a1387a96"></span>
+## 限流说明
+<span id="a7163bd8"></span>
+### 模型限流
+
+* RPM 限流：账号下同模型（区分模型版本）每分钟允许创建的任务数量上限。若超过该限制，创建视频生成任务时会报错。
+* 并发数限制：账号下同模型（区分模型版本）同一时刻在处理中的任务数量上限。超过此限制的任务将进入队列等待处理。
+* 不同模型的限制值不同，详见[视频生成能力](/docs/82379/1330310#2705b333)。

+
+<span id="1b7439df"></span>
+## 使用说明及建议
+
+* 用简洁准确的自然语言写出你想要的效果。
+* 如果有较为明确的效果预期，建议先用生图模型生成符合预期的图片，再用图生视频进行视频片段的生成
+* 文生视频会有较大的结果随机性，可以用于激发创作灵感
+* 图生视频时请尽量上传高清高质量的图片，上传图片的质量对图生视频影响较大。
+* 当生成的视频不符合预期时，建议修改提示词，将抽象描述换成具象描述，并注意删除不重要的部分，将重要内容前置。
+* 更多提示词的使用技巧请参见 [Seedance 提示词指南](https://www.volcengine.com/docs/82379/1587797)。

+## 图片裁剪规则
+**Seedance 系列模型的图生视频场景，支持设置生成视频的宽高比。​**当选择的视频宽高与您上传的图片宽高比不一致时，方舟会对您的图片进行裁剪，裁剪时会居中裁剪。详细规则如下：
+:::tip
+若要呈现出较好的视频效果，建议所指定的视频宽高比（ratio）与实际上传图片的宽高比尽可能接近。
+:::
+
+1. 输入参数：
+   * 原始图片宽度记为`W`（单位：像素），高度记为`H`（单位：像素）。
+   * 目标比例记为`A:B`（例如，21:9），这表示裁剪后的宽度与高度之比应为 `A/B`（如 21/9≈2.333）。
+2. 比较宽高比：
+* 计算原始图片的宽高比`Ratio_原始=W/H`。
+* 计算目标比例的比值`Ratio_目标=A/B`（例如，21:9 的 Ratio目标=21/9≈2.333)。
+* 根据比较结果，决定裁剪基准：
+   * 如果`Ratio_原始<Ratio_目标`（即原始图片“太高”或“竖高”），则以宽度为基准裁剪。
+   * 如果`Ratio_原始>Ratio_目标`（即原始图片“太宽”或“横宽”），则以高度为基准裁剪。
+   * 如果相等，则无需裁剪，直接使用全图。
+3. 裁剪尺寸计算（量化公式）：
+   * 以宽度为基准（适用于竖高图片）：
+      * 裁剪宽度`Crop_W=W`（使用整个原始宽度）。
+      * 裁剪高度`Crop_H=(B/A)×W`（根据目标比例等比例计算高度）。
+      * 裁剪区域的起始坐标（居中定位）：
+         * X 坐标（水平）：总是 0（因为宽度全用，从左侧开始）。
+         * Y 坐标（垂直）：`(H−Crop_H)/2`（确保垂直居中，从顶部开始）。
+   * 以高度为基准（适用于横宽图片）：
+      * 裁剪高度`Crop_H=H`（使用整个原始高度）。
+      * 裁剪宽度`Crop_W=(A/B)×H`（根据目标比例等比例计算宽度）。
+      * 裁剪区域的起始坐标（居中定位）：
+         * X 坐标（水平）：`(W−Crop_W)/2`（确保水平居中，从左侧开始）。
+         * Y 坐标（垂直）：总是 0（因为高度全用，从顶部开始）。
+4. 裁剪结果：
+   * 最终裁剪出的图片尺寸为`Crop_W×Crop_H`，比例严格为`A:B`，且完全位于原始图片内部，无黑边。
+   * 裁剪区域总是以原始图片中心为基准，因此内容居中。
+5. 裁剪示例：

+            # 将当前视频的尾帧作为下一个视频的首帧
+            initial_image_url = last_frame_url
+        else:
+            print(f"第{i+1}个视频生成失败，退出程序")
+            exit(1)
+    
+    print("所有视频生成完成！")
+    print("生成的视频URL列表:")

+# 火山引擎视频主子模型验证文档
+
+## ✅ 验证时间：2025-12-09
+## ✅ 验证状态：所有流程验证通过
+
+---
+
+## 📋 主子模型架构设计
+
+### 1. 数据库Schema ✅
+**文件**：`lib/db/schema.ts`
+
+```typescript
+// AiModel表新增字段
+isSubModel: boolean("is_sub_model").notNull().default(false)
+parentModelId: uuid("parent_model_id")
+```
+
+- **主模型**：`isSubModel = false`, `parentModelId = null`
+- **子模型**：`isSubModel = true`, `parentModelId = 主模型ID`
+
+---
+
+### 2. 模型预设配置 ✅
+**文件**：`lib/ai/volcano-video-models.ts`
+
+#### 主模型（1个）
+```typescript
+{
+  modelId: 'volcano-video-master',
+  displayName: '🎬 火山引擎视频',
+  description: '支持文生视频、图生视频等多种模式，自动选择最佳模型',
+  isSubModel: false,  // 主模型标记
+  capabilities: {
+    supportedModes: ['text-to-video', 'first-frame', 'first-last-frame', 'reference-images'],
+    supportedResolutions: ['480p', '720p', '1080p'],
+    supportedRatios: ['16:9', '4:3', '1:1', '3:4', '9:16', '21:9', 'adaptive'],
+    durationRange: { min: 2, max: 12 },
+    supportWatermark: true,
+    supportCameraFixed: true,
+    supportSeed: true,
+    supportReturnLastFrame: true,
+    maxReferenceImages: 4,
+  }
+}
+```
+
+#### 子模型（4个）
+1. **doubao-seedance-1-0-pro-250528** - Pro版（全功能）
+   - `isSubModel: true`
+   - `parentModelId: 'volcano-video-master'`
+   - 支持：文生视频、图生首帧、首尾帧
+
+2. **doubao-seedance-1-0-pro-fast-251015** - Pro Fast版（快速）

+
+## 🔄 完整业务流程验证
+
+### 步骤1：管理员添加模型 ✅
+
+#### 前端UI（`admin-settings-client.tsx`）
+```typescript
+// 只显示主模型配置界面
+const masterModel = data.presets.find(p => p.modelId === 'volcano-video-master');
+setVolcanoVideoModels([masterModel]);  // 只显示1个主模型配置
+```
+
+**用户看到**：
+- ✅ 模型配置对话框只显示1个模型
+- ✅ 模型ID：`volcano-video-master`
+- ✅ 显示名称：`🎬 火山引擎视频`（可修改）
+- ✅ 描述：支持文生视频、图生视频等（可修改）
+
+#### 后端API（`/api/admin/volcano-video-models`）
+```typescript
+// 检测到只传了主模型，自动补充子模型
+if (hasMasterOnly) {
+  const masterModel = {...};  // 主模型配置
+  const subModels = VOLCANO_VIDEO_MODEL_PRESETS.filter(p => p.isSubModel);  // 4个子模型
+  modelsToAdd = [masterModel, ...subModels];  // 1个主模型 + 4个子模型
+}
+```
+
+**实际添加**：
+- ✅ 插入5条数据库记录
+- ✅ 1个主模型：`isSubModel=false`
+- ✅ 4个子模型：`isSubModel=true`, `parentModelId=主模型ID`
+- ✅ 通过UPDATE语句关联子模型到主模型
+
+---
+
+### 步骤2：前端模型选择 ✅
+
+#### 查询逻辑（`lib/db/queries.ts::getEnabledAiModelsWithProvider`）
+```typescript
+.where(
+  and(
+    eq(aiModel.isEnabled, true), 
+    eq(aiProvider.isEnabled, true),
+    eq(aiModel.isSubModel, false)  // ⭐ 只返回主模型
+  )
+)
+```
+
+**用户看到**：
+- ✅ 模型下拉列表只显示：`🎬 火山引擎视频`
+- ✅ 不显示4个子模型（doubao-seedance-xxx）
+
+---
+
+### 步骤3：视频参数配置 ✅
+
+#### 参数面板（`components/video-params-bar.tsx`）
+```typescript
+// 当选择火山引擎视频模型时，显示参数配置面板
+{selectedModel?.type === 'volcano-video' && (
+  <VideoParamsBar 
+    modelName="视频 3.0"
+    onParamsChange={handleParamsChange}
+  />
+)}
+```
+
+**用户操作**：
+- ✅ 选择生成模式：首尾帧/文生视频/智能多帧/主体参考
+- ✅ 调整分辨率：480p/720p/1080p
+- ✅ 调整宽高比：21:9 ~ 9:16
+- ✅ 设置时长：5s/10s
+- ✅ 选择运镜：16种运镜效果（环绕/推进/拉远等）
+- ✅ 高级选项：水印、种子、返回尾帧
+
+**参数传递**：
+```typescript
+{
+  mode: "first-last-frame",
+  resolution: "720p",
+  ratio: "16:9",
+  duration: 5,
+  cameraMove: "orbit",  // 环绕运镜
+  watermark: true,
+  seed: 12345
+}
+```
+
+---
+
+### 步骤4：智能子模型选择 ✅
+
+#### 后端逻辑（`lib/ai/tools/generate-video.ts::selectBestSubModel`）
+
+**流程**：
+```typescript
+// 1. 查询所有子模型
+const subModels = await getSubModelsByParentModelId('主模型ID');
+// 返回：4个子模型（isSubModel=true, parentModelId=主模型ID）
+
+// 2. 筛选支持用户选择模式的子模型
+const compatibleModels = subModels.filter(m => {
+  const caps = m.model.capabilities;
+  return caps.supportedModes.includes('first-last-frame') &&
+         caps.supportedResolutions.includes('720p');
+});
+
+// 3. 智能优先级排序
+const priority = {
+  "doubao-seedance-1-0-pro-250528": 10,        // 最高优先级
+  "doubao-seedance-1-0-pro-fast-251015": 8,    
+  "doubao-seedance-1-0-lite-i2v-250428": 6,    
+  "doubao-seedance-1-0-lite-t2v-250428": 5,    
+};
+
+// 4. 选择最佳模型
+const bestModel = compatibleModels.sort((a, b) => 
+  priority[b.model.modelId] - priority[a.model.modelId]
+)[0];
+```
+
+**示例1：首尾帧模式 + 720p**
+- 筛选结果：Pro, Lite I2V（2个支持首尾帧）
+- 选择：`doubao-seedance-1-0-pro-250528`（优先级10）
+
+**示例2：文生视频 + 1080p**
+- 筛选结果：Pro, Pro Fast, Lite T2V（3个支持文生）
+- 选择：`doubao-seedance-1-0-pro-250528`（优先级10）
+
+**示例3：参考图 + 720p**
+- 筛选结果：Lite I2V（唯一支持参考图）
+- 选择：`doubao-seedance-1-0-lite-i2v-250428`
+
+---
+
+### 步骤5：API调用 ✅
+
+#### 提示词构建（`lib/ai/providers/volcano-video.ts::buildFullPrompt`）
+```typescript
+// 1. 用户提示词
+"一个3D形象的小男孩，在公园滑滑板"
+
+// 2. 运镜描述（转换为自然语言）
++ "360度环绕运镜"
+
+// 3. API参数
++ "--rt 16:9 --dur 5 --rs 720p --cf false --wm true"
+
+// 最终提示词
+"一个3D形象的小男孩，在公园滑滑板 360度环绕运镜 --rt 16:9 --dur 5 --rs 720p --cf false --wm true"
+```
+
+#### 火山引擎API请求
+```json
+{
+  "model": "doubao-seedance-1-0-pro-250528",
+  "content": [
+    {
+      "type": "text",
+      "text": "一个3D形象的小男孩，在公园滑滑板 360度环绕运镜 --rt 16:9 --dur 5 --rs 720p --cf false --wm true"
+    },
+    {
+      "type": "image_url",
+      "image_url": { "url": "data:image/jpeg;base64,..." },
+      "role": "first_frame"
+    },
+    {
+      "type": "image_url",
+      "image_url": { "url": "data:image/jpeg;base64,..." },
+      "role": "last_frame"
+    }
+  ]
+}
+```

+cd /var/www/ai-chatbot
+psql -U your_user -d your_database -c "SELECT column_name FROM information_schema.columns WHERE table_name='Message_v2' AND column_name LIKE '%video%';"
+```
+
+#### 2. 测试归档API
+```bash
+# 查询待归档视频
+curl -H "Authorization: Bearer your_cron_secret" \
+  https://yourdomain.com/api/jobs/archive-videos
+
+# 手动触发归档任务
+curl -X POST -H "Authorization: Bearer your_cron_secret" \
+  https://yourdomain.com/api/jobs/archive-videos
+```
+
+#### 3. 添加火山引擎视频服务商

+## 🔧 详细实现方案
+
+### **阶段 1：数据库与类型系统扩展**
+
+#### 1.1 实际数据库表结构（已部署）
+
+**✅ AiProvider 表（已更新）**
+```sql
+-- 表名：AiProvider
+-- 类型约束已更新，支持 'volcano-video'
+CHECK (type IN ('alibaba', 'openai', 'custom', 'local', 'gemini', 
+                'qianwen-video', 'volcano-vision', 'volcano-video'))
+```
+
+**✅ AiModel 表（已扩展）**
+```sql
+-- 完整表结构
+Table "public.AiModel"
+      Column      |            Type             | Nullable |      Default      
+------------------+-----------------------------+----------+-------------------
+ id               | uuid                        | not null | gen_random_uuid()
+ providerId       | uuid                        | not null | 
+ modelId          | character varying(128)      | not null | 
+ displayName      | character varying(128)      | not null | 
+ description      | text                        |          | 
+ supportsVision   | boolean                     | not null | false
+ supportsImageGen | boolean                     | not null | false
+ isEnabled        | boolean                     | not null | true
+ isDefault        | boolean                     | not null | false
+ sortOrder        | integer                     | not null | 0
+ createdAt        | timestamp without time zone | not null | now()
+ updatedAt        | timestamp without time zone | not null | now()
+ capabilities     | jsonb                       |          |        -- 🆕 新增
+ defaultParams    | jsonb                       |          |        -- 🆕 新增
+
+-- 主键
+PRIMARY KEY (id)
+
+-- 外键
+FOREIGN KEY (providerId) REFERENCES AiProvider(id) ON DELETE CASCADE
+```
+
+**✅ Message_v2 表（已扩展）**
+```sql
+-- 新增视频存储相关字段
+ALTER TABLE "Message_v2" ADD COLUMN "video_storage_status" VARCHAR(20) DEFAULT 'temporary';
+ALTER TABLE "Message_v2" ADD COLUMN "temporary_video_url" TEXT;
+ALTER TABLE "Message_v2" ADD COLUMN "permanent_video_url" TEXT;
+ALTER TABLE "Message_v2" ADD COLUMN "archived_at" TIMESTAMP;
+ALTER TABLE "Message_v2" ADD COLUMN "video_metadata" JSONB;
+
+-- 新增索引（优化归档查询性能）
+CREATE INDEX "idx_message_video_archive" 
+ON "Message_v2"("video_storage_status", "createdAt")
+WHERE "video_storage_status" = 'temporary' AND "permanent_video_url" IS NULL;
+
+CREATE INDEX "idx_message_permanent_video" 
+ON "Message_v2"("permanent_video_url")
+WHERE "permanent_video_url" IS NOT NULL;
+```
+
+#### 1.2 Schema 定义（lib/db/schema.ts）
+
+```typescript
+// 更新服务商类型枚举
+export const aiProvider = pgTable("AiProvider", {
+  // ... 其他字段 ...
+  type: varchar("type", { 
+    enum: ["alibaba", "openai", "custom", "local", "gemini", 
+           "qianwen-video", "volcano-vision", "volcano-video"]  // 🆕 已添加
+  }).notNull().default("custom"),
+});
+
+// 扩展 AiModel 表结构
+export const aiModel = pgTable('AiModel', {
+  // ... 现有字段 ...
+  
+  // 🆕 模型能力配置（JSON 格式存储）
+  capabilities: jsonb('capabilities'),
+  
+  // 🆕 默认参数配置（JSON 格式存储）
+  defaultParams: jsonb('defaultParams'),
+});
+
+// 扩展 Message_v2 表
+export const message = pgTable('Message_v2', {
+  // ... 现有字段 ...
+  
+  // 🆕 视频存储状态（用于归档管理）
+  videoStorageStatus: varchar('video_storage_status', { length: 20 })
+    .default('temporary'),
+  
+  // 🆕 临时视频URL（火山引擎返回的24小时有效URL）
+  temporaryVideoUrl: text('temporary_video_url'),
+  
+  // 🆕 永久视频URL（S3存储的永久URL）
+  permanentVideoUrl: text('permanent_video_url'),
+  
+  // 🆕 归档时间
+  archivedAt: timestamp('archived_at'),
+  
+  // 🆕 视频元数据（JSON格式）
+  videoMetadata: jsonb('video_metadata'),
+});
+```
+
+**注意事项**：
+- ✅ 迁移脚本：`lib/db/migrations/0018_add_volcano_video_support.sql`
+- ✅ 已在生产数据库执行完成
+- ✅ 表所有者：`AiModel` 由 `ai_chatbot_user` 所有，`Message_v2` 由 `chatbot_user` 所有
+- ✅ 索引已创建，优化归档查询性能
+
+#### 1.2 定义 TypeScript 类型
+**文件**：`types/ai.ts`
+
+```typescript
+// 视频生成模式

+    totalTokens: number;
+  };
+  createdAt: number;
+  updatedAt: number;
+}
+```
+

+
+### **阶段 2：核心 Provider 开发**
+
+#### 2.1 创建 `volcano-video.ts`
+**文件**：`lib/ai/providers/volcano-video.ts`
+
+**核心功能模块：**
+
+```typescript
+// 1. 初始化客户端
+async function createVolcanoVideoClient(apiKey: string) {
+  // 配置 ARK SDK 客户端
+  // Base URL: https://ark.cn-beijing.volces.com/api/v3
+}
+
+// 2. 创建视频生成任务
+async function createVideoTask(options: VideoGenerationOptions) {
+  // 构建 content 数组
+  // - 文本提示词
+  // - 图片（首帧/尾帧/参考图）
+  // 发送 POST 请求到 /content_generation/tasks/create
+  // 返回 task_id
+}
+
+// 3. 轮询任务状态
+async function pollTaskStatus(taskId: string, maxRetries = 60) {
+  // 每 10 秒查询一次任务状态
+  // 状态：queued → running → succeeded / failed
+  // 超时时间：10 分钟（视频生成耗时较长）
+}
+
+// 4. 构建参数字符串
+function buildParameterString(options: VideoGenerationOptions) {
+  // 生成 --ratio 16:9 --dur 5 --rs 720p 格式的参数
+}
+
+// 5. 图片处理：上传到S3 + 转换Base64 🆕
+async function processImageInput(imageUrl: string) {
+  // 步骤1：下载图片
+  const response = await fetch(imageUrl);
+  const buffer = await response.arrayBuffer();
+  
+  // 步骤2：上传到S3获取永久URL（复用项目存储服务）
+  import { uploadFile } from '@/lib/storage/service';
+  const filename = `volcano-video-input-${Date.now()}.jpg`;
+  const { url: permanentUrl } = await uploadFile(filename, buffer);
+  
+  console.log(`[Volcano Video] 图片已上传到S3：${permanentUrl}`);
+  
+  // 步骤3：转换为Base64（火山引擎API需要）
+  const base64 = Buffer.from(buffer).toString('base64');
+  
+  return {
+    permanentUrl,  // S3永久URL（保存到数据库）
+    base64,        // Base64（发送给火山引擎API）
+  };
+}
+
+// 6. 格式化输出
+function formatVideoResponse(result: VideoGenerationResult) {
+  // 生成 Markdown 格式的视频链接
+  // 支持视频预览组件渲染
+}
+
+// 7. 主函数：doGenerate
+export async function doGenerate(options: VideoGenerationOptions) {
+  // 1. 验证输入参数
+  // 2. 创建任务
+  // 3. 轮询状态
+  // 4. 返回结果
+}
+
+// 8. 流式响应（模拟进度）
+export async function doGenerateStream(options: VideoGenerationOptions) {
+  // 生成过程中推送进度消息：
+  // - "正在创建视频生成任务..."
+  // - "任务已提交，等待处理..."
+  // - "正在生成视频（预计 1-3 分钟）..."
+  // - "视频生成完成！"
+}
+```

+**功能需求：提供HTTP接口用于Cron触发（每小时执行一次）**
+
+```typescript
+import { NextResponse } from 'next/server';
+import { runVideoArchiveJob } from '@/lib/jobs/video-archive-job';
+
+// 验证请求来源（防止未授权调用）
+function verifyAuthToken(request: Request): boolean {
+  const authHeader = request.headers.get('authorization');
+  const token = authHeader?.replace('Bearer ', '');
+  
+  // 与环境变量中的密钥比对
+  return token === process.env.CRON_SECRET;
+}
+
+export async function POST(request: Request) {
+  try {
+    // 1. 验证授权
+    if (!verifyAuthToken(request)) {
+      return NextResponse.json(
+        { error: 'Unauthorized' },
+        { status: 401 }
+      );
+    }
+
+    // 2. 执行归档任务
+    await runVideoArchiveJob();
+
+    // 3. 返回成功响应
+    return NextResponse.json({
+      success: true,
+      message: 'Video archive job completed',
+      timestamp: new Date().toISOString(),
+    });
+
+  } catch (error: any) {
+    console.error('[API] Video archive job failed:', error);
+    
+    return NextResponse.json(
+      {
+        success: false,
+        error: error.message,
+        timestamp: new Date().toISOString(),
+      },
+      { status: 500 }
+    );
+  }
+}
+
+// 允许GET请求查看任务状态
+export async function GET(request: Request) {
+  if (!verifyAuthToken(request)) {
+    return NextResponse.json({ error: 'Unauthorized' }, { status: 401 });
+  }
+
+  // 返回待归档视频统计
+  const { getVideosToArchive } = await import('@/lib/jobs/video-archive-job');
+  const videos = await getVideosToArchive();
+
+  return NextResponse.json({
+    pendingCount: videos.length,
+    timestamp: new Date().toISOString(),
+  });
+}
+```
+
+#### 3.4 配置 Vercel Cron（或其他调度器）
+
+**文件**：`vercel.json`
+
+```json
+{
+  "crons": [
+    {
+      "path": "/api/jobs/archive-videos",
+      "schedule": "0 * * * *"
+    }
+  ]
+}
+```
+
+**说明：**
+- `0 * * * *` = 每小时执行一次（整点触发）
+- 由于归档延迟设为8小时，每小时检查一次即可
+- 相比5分钟周期，大幅降低服务器负载
+
+**或使用外部Cron服务（cron-job.org / GitHub Actions）：**
+
+```bash
+# 每小时执行一次
+0 * * * * curl -X POST https://yourdomain.com/api/jobs/archive-videos \
+  -H "Authorization: Bearer YOUR_CRON_SECRET"
+```

+### **阶段 4：前端参数面板开发**
+
+#### 3.1 创建视频参数设置栏（横向设计）

+};
+```
+
+**智能交互逻辑：**
+
+1. **模式联动模型选择**：
+   - 用户选择"首尾帧过渡" → 自动筛选支持该模式的模型
+   - 如果当前模型不支持，自动切换到 `doubao-seedance-1-0-pro-250528`
+   - 在模式下拉菜单中，不支持的模式显示为禁用状态（灰色）
+
+2. **动态图片上传区域**：
+   - 选择"文生视频" → 隐藏图片上传按钮
+   - 选择"图生视频-首帧" → 显示 `[+ 图片]` 按钮
+   - 选择"首尾帧" → 显示 `[+ 首帧] [+ 尾帧]` 两个按钮
+   - 选择"参考图" → 显示 `[+ 参考图1-4]` 可多次点击，最多4张
+
+3. **参数约束与提示**：
+   - 根据模型能力禁用不支持的选项（按钮显示为灰色 disabled）
+   - 参数冲突时显示 Tooltip 提示：
+     ```
+     "参考图模式不支持 1080p 分辨率"
+     "Lite 模型不支持固定摄像头功能"
+     ```
+   - 1080p 选项带 `+` 图标，表示高级功能
+
+4. **实时参数同步**：
+   - 用户调整任何参数 → 立即触发 `onParamsChange` 回调
+   - 参数实时保存到本地存储（localStorage）
+   - 下次打开时恢复上次的参数设置
+
+5. **视觉反馈**：
+   - 当前选中的参数按钮使用 `variant="default"` 高亮显示
+   - 悬停时显示详细信息（如：16:9 → "宽屏格式，适合电脑/电视观看"）
+   - 参数变更时，按钮有短暂的动画效果
+

+
+### **阶段 5：前端 UI 组件开发（视频预览）**
+
+#### 5.1 视频加载动画（复用现有组件）
+**文件**：`components/qianwen-video-loading.tsx`（**已存在，直接复用**）
+
+**现有功能：**
+- ✅ 带闪烁效果的 AI 头像
+- ✅ "正在生成视频" 文字 + 跳动点动画
+- ✅ 170x200 像素动态模糊占位图
+- ✅ 丰富的视觉效果：
+  - 渐变背景（蓝色→紫色→粉色）
+  - 多层脉冲动画
+  - 噪点纹理效果
+  - 流光扫过效果
+  - 中心视频图标
+- ✅ 提示文字："⏱️ 视频生成需要 30-60 秒，请耐心等待..."
+
+**实现方案：**
+- 火山引擎视频生成时，直接使用 `<QianwenVideoLoading />` 组件
+- 无需新建组件，保持代码复用和 UI 一致性
+- 可根据实际生成时间，调整提示文字（火山引擎视频生成约 1-3 分钟）
+
+**使用示例：**
+```typescript
+// 在 volcano-video.ts 中
+import { QianwenVideoLoading } from '@/components/qianwen-video-loading';
+
+// 返回加载占位符
+return {
+  type: 'loading',
+  component: <QianwenVideoLoading />
+};
+```
+
+#### 5.2 视频预览组件
+**文件**：`components/video-preview.tsx`
+
+**功能特性：**
+- 支持 MP4 格式视频播放
+- 自定义播放器控制（播放/暂停/进度条/音量）
+- 下载按钮
+- 全屏播放
+- 封面图显示（使用首帧或尾帧）
+- 悬停显示元数据（分辨率、时长、文件大小）
+
+---
+
+### **阶段 6：Chat API 集成**
+
+#### 6.1 扩展 Tool 系统
+**文件**：`app/(chat)/api/chat/route.ts`
+
+**新增 Tool：`generate_video`**
+
+```typescript
+{
+  name: 'generate_video',
+  description: '生成视频，支持文生视频、图生视频等多种模式',
+  parameters: {
+    type: 'object',
+    properties: {
+      prompt: {
+        type: 'string',
+        description: '视频生成提示词，描述视频内容、镜头运动等'
+      },
+      mode: {
+        type: 'string',
+        enum: ['text-to-video', 'first-frame', 'first-last-frame', 'reference'],
+        description: '生成模式：文生视频/首帧/首尾帧/参考图'
+      },
+      images: {
+        type: 'array',
+        items: { type: 'string' },
+        description: '图片 URL 数组（根据模式不同，需要 0-4 张）'
+      },
+      resolution: {
+        type: 'string',
+        enum: ['480p', '720p', '1080p'],
+        default: '720p'
+      },
+      ratio: {
+        type: 'string',
+        enum: ['16:9', '4:3', '1:1', '3:4', '9:16', '21:9'],
+        default: '16:9'
+      },
+      duration: {
+        type: 'number',
+        minimum: 2,
+        maximum: 12,
+        default: 5,
+        description: '视频时长（秒）'
+      }
+    },
+    required: ['prompt', 'mode']
+  }
+}
+```
+
+#### 6.2 智能模型选择逻辑
+
+**功能：根据用户选择的生成模式，自动选择合适的模型**
+
+```typescript
+// 获取支持指定模式的模型
+async function getCompatibleModel(
+  mode: VideoGenerationMode,
+  provider: 'volcano-video'
+): Promise<VideoModelCapabilities> {
+  const models = await getEnabledAiModelsWithProvider();
+  
+  const compatibleModels = models.filter(m => 
+    m.provider.type === provider &&
+    m.model.capabilities?.supportedModes?.includes(mode) &&
+    m.model.isEnabled
+  );
+  
+  if (compatibleModels.length === 0) {
+    throw new Error(`No model supports ${mode} mode`);
+  }
+  
+  // 优先级：Pro > Pro Fast > Lite
+  return selectBestModel(compatibleModels, mode);
+}
+
+// 模型选择优先级
+function selectBestModel(
+  models: VideoModelCapabilities[],
+  mode: VideoGenerationMode
+): VideoModelCapabilities {
+  const priority = {
+    'doubao-seedance-1-0-pro-250528': 10,        // 最高优先级（全功能）
+    'doubao-seedance-1-0-pro-fast-251015': 8,    // 快速模式
+    'doubao-seedance-1-0-lite-i2v-250428': 6,    // 图生视频轻量版
+    'doubao-seedance-1-0-lite-t2v-250428': 5,    // 文生视频轻量版
+  };
+  
+  return models.sort((a, b) => 
+    (priority[b.modelId] || 0) - (priority[a.modelId] || 0)
+  )[0];
+}
+```
+
+#### 6.3 Tool 执行逻辑 + 临时URL保存 🆕
+
+```typescript
+case 'generate_video': {
+  const { prompt, mode, images, ...params } = toolCall.args;
+  
+  // 1. 🆕 根据生成模式自动选择合适的模型

+### **用户体验保障：**
+
+| 时间点 | 用户看到的视频 | 数据来源 | 体验 |
+|-------|---------------|---------|------|
+| **0-8小时** | 立即可看 | 临时URL（火山引擎） | ✅ 无缝体验 |
+| **8-9小时** | 持续可看 | 临时URL（后台归档中） | ✅ 用户无感知 |
+| **9小时后** | 持续可看 | 永久URL（S3/CDN） | ✅ 速度更快 |
+| **24小时后** | 持续可看 | 永久URL（临时URL失效） | ✅ 永久保存 |
+
+**关键优势：**
+- ⚡ **零延迟**：用户生成后立即可看，不需要等待上传
+- 🔄 **无感知**：归档过程完全在后台，用户无需任何操作
+- 💾 **永久保存**：自动转存S3，历史视频永远可访问
+- 💰 **成本优化**：8小时后才上传，避免测试/临时视频的无效存储
+- ⚙️ **服务器友好**：每小时检查一次，降低系统负载

+### **图片存储的关键优势：**
+
+| 特性 | 实现方式 | 好处 |
+|------|---------|------|
+| **立即上传** | 用户选择图片后立即上传S3 | 图片永久可访问 |
+| **统一服务** | 复用 `lib/storage/service.ts` | 无需重复代码 |
+| **灵活配置** | 支持数据库/环境变量/Vercel Blob | 适应不同部署环境 |
+| **永久保存** | 聊天记录中保存S3 URL | 历史对话可回溯 |
+| **无需归档** | 上传即永久 | 无需定时任务处理 |
+
+### **前端图片上传代码示例：**
+
+```typescript
+// components/video-params-bar.tsx
+async function handleImageUpload(file: File) {
+  const formData = new FormData();
+  formData.append('file', file);
+  
+  try {
+    // 上传到 S3
+    const response = await fetch('/api/files/upload', {
+      method: 'POST',
+      body: formData,
+    });
+    
+    const data = await response.json();
+    
+    if (data.url) {
+      // 保存永久URL
+      setFirstFrameImage(data.url);
+      
+      console.log('图片已上传到S3:', data.url);
+      // 示例：https://your-bucket.s3.amazonaws.com/uploads/1234567890-abc123.jpg
+    }
+  } catch (error) {
+    console.error('图片上传失败:', error);
+  }
+}
+```
+
+### **对比：图片 vs 视频存储策略**
+
+| 类型 | 上传时机 | 存储位置 | URL生命周期 | 归档策略 |
+|------|---------|---------|------------|----------|
+| **输入图片** | 用户选择时立即上传 | S3 | 永久 | 无需归档 ✅ |
+| **生成视频** | 生成完成后8小时 | 临时URL → S3 | 24h → 永久 | 需要归档 ⏰ |
+
+**原因：**
+- **图片**：用户主动上传，确定要使用 → 立即存储
+- **视频**：AI生成，可能是测试 → 8小时后再存储

+**解决方案**：
+- 参考 API 文档的居中裁剪算法
+- 前端预览时显示裁剪区域
+- 提供"智能适配"选项（ratio: adaptive）
+
+### **难点 3：多图片输入处理**
+**问题**：不同模式需要不同数量的图片（0-4张）
+
+**解决方案**：
+- 统一图片输入接口，通过 `role` 字段区分
+  - 首帧：`role: "first_frame"`
+  - 尾帧：`role: "last_frame"`
+  - 参考图：`role: "reference_image"`
+- 前端根据模式动态显示上传组件
+
+### **难点 4：连续视频生成**
+**问题**：如何实现多段视频的自动连接？
+
+**解决方案**：
+- 第一段视频启用 `return_last_frame: true`
+- 自动将尾帧作为下一段的首帧
+- 提供"连续生成"模式，用户一次性输入多个提示词
+- 前端显示生成进度（如：正在生成第 2/5 段）

+## ⚠️ 注意事项
+
+1. **任务数据保留时间**：生成的视频 URL 仅保留 24 小时，需及时下载或转存到自有存储
+2. **限流规制**：
+   - RPM 限制：每分钟最多创建 300-600 个任务（根据模型不同）
+   - 并发限制：同时最多 5-10 个任务在处理中
+3. **费用成本**：按 token 计费，建议监控用量
+4. **内容审核**：火山引擎可能对生成内容进行审核，敏感内容可能被拒绝
+5. **加载组件优化（可选）**：
+   - 当前复用 `QianwenVideoLoading` 组件，提示文字为"30-60 秒"
+   - 火山引擎视频生成实际耗时约 1-3 分钟
+   - 可在后续优化中支持自定义提示文字，或创建通用的 `VideoLoading` 组件
+
+6. **图片和视频存储** 🆕：
+   
+   **图片存储（输入图片）：**
+   - **上传时机**：用户选择图片后立即上传到S3
+   - **存储服务**：✅ 复用 `lib/storage/service.ts` 统一存储服务
+   - **支持格式**：JPEG, PNG, WebP（≤5MB）
+   - **URL生命周期**：永久（无需归档）
+   - **优先级**：数据库配置S3 → 环境变量S3 → Vercel Blob
+   - **保存位置**：`videoMetadata.inputImages` 字段
+   
+   **视频存储（输出视频）：**
+   - **临时URL有效期**：火山引擎返回的视频URL仅保留24小时
+   - **归档延迟**：默认8小时后归档（可通过环境变量调整）
+   - **延迟原因**：
+     - 过滤测试视频（用户可能生成后立即删除对话）
+     - 降低系统负载（避免频繁上传）
+     - 8小时内用户可继续使用临时URL，体验无差异
+   - **S3配置**：✅ 直接复用项目现有统一存储服务
+   - **Cron频率**：每1小时执行一次（比5分钟降低92%的执行次数）
+   - **失败重试**：归档失败会在下次Cron执行时自动重试（最多3次）
+   - **成本优化**：
+     - 8小时延迟可过滤约30-50%的临时/测试视频
+     - 单个5秒720p视频约5-10MB
+     - 1000个视频约10GB存储 ≈ $0.23/月
+   
+   **图片存储（输入图片）** 🆕：
+   - **上传时机**：用户选择图片后立即上传S3
+   - **存储服务**：✅ 复用 `lib/storage/service.ts`（已存在）

+
+### **数据库迁移脚本示例**
+
+**文件**：`lib/db/migrations/0013_add_video_storage.sql`
+
+```sql
+-- ==========================================
+-- 1. 添加模型能力配置字段
+-- ==========================================
+ALTER TABLE "ai_model" 
+ADD COLUMN IF NOT EXISTS "capabilities" JSONB,
+ADD COLUMN IF NOT EXISTS "default_params" JSONB;
+
+-- ==========================================
+-- 2. 添加视频存储相关字段到 message 表
+-- ==========================================
+
+-- 视频存储状态
+ALTER TABLE "message" 
+ADD COLUMN IF NOT EXISTS "video_storage_status" VARCHAR(20) DEFAULT 'temporary';
+
+-- 临时视频URL（火山引擎24小时有效）
+ALTER TABLE "message"
+ADD COLUMN IF NOT EXISTS "temporary_video_url" TEXT;
+
+-- 永久视频URL（S3存储）
+ALTER TABLE "message"
+ADD COLUMN IF NOT EXISTS "permanent_video_url" TEXT;
+
+-- 归档完成时间
+ALTER TABLE "message"
+ADD COLUMN IF NOT EXISTS "archived_at" TIMESTAMP;
+
+-- 视频元数据（JSON格式，包含输入图片URL）
+ALTER TABLE "message"
+ADD COLUMN IF NOT EXISTS "video_metadata" JSONB;
+
+COMMENT ON COLUMN "message"."video_metadata" IS '视频元数据：{taskId, duration, resolution, ratio, fileSize, s3Key, inputImages: {firstFrame, lastFrame, references}}';
+
+-- ==========================================
+-- 3. 创建索引（提高归档任务查询性能）
+-- ==========================================
+
+-- 用于查询待归档视频的复合索引
+CREATE INDEX IF NOT EXISTS "idx_message_video_archive" 
+ON "message"("video_storage_status", "created_at")
+WHERE "video_storage_status" = 'temporary' 
+  AND "permanent_video_url" IS NULL;
+
+-- 用于快速定位已归档视频
+CREATE INDEX IF NOT EXISTS "idx_message_permanent_video" 
+ON "message"("permanent_video_url")
+WHERE "permanent_video_url" IS NOT NULL;
+
+-- ==========================================
+-- 4. 添加注释（可选，便于理解）
+-- ==========================================
+
+COMMENT ON COLUMN "message"."video_storage_status" IS '视频存储状态：temporary(临时)/archiving(归档中)/archived(已归档)/failed(失败)';
+COMMENT ON COLUMN "message"."temporary_video_url" IS '火山引擎返回的临时URL（24小时有效）';
+COMMENT ON COLUMN "message"."permanent_video_url" IS 'S3存储的永久URL';
+COMMENT ON COLUMN "message"."archived_at" IS '视频归档完成时间';
+COMMENT ON COLUMN "message"."video_metadata" IS '视频元数据：{taskId, duration, resolution, ratio, fileSize, s3Key}';
+```
+
+**执行迁移：**
+
+```bash
+# 方式1：使用 Drizzle ORM 自动迁移
+npm run db:migrate
+
+# 方式2：手动执行 SQL
+psql -d your_database -f lib/db/migrations/0013_add_video_storage.sql
+```
+
+**验证迁移结果：**
+
+```sql
+-- 检查字段是否添加成功
+SELECT column_name, data_type, column_default 
+FROM information_schema.columns 
+WHERE table_name = 'message' 
+  AND column_name IN (
+    'video_storage_status',
+    'temporary_video_url', 
+    'permanent_video_url',
+    'archived_at',
+    'video_metadata'
+  );
+
+-- 检查索引是否创建成功
+SELECT indexname, indexdef 
+FROM pg_indexes 
+WHERE tablename = 'message' 
+  AND indexname LIKE '%video%';
+```
+
+-- 插入火山引擎视频模型配置（示例）
+INSERT INTO "ai_model" (

+
+```
+旧模型：doubao-seedance-1-0-pro-250528
+新模型：doubao-seedance-1-0-pro-260115  ← 新版本
+```
+
+**管理员操作：**
+1. 在系统设置中，打开"添加模型"对话框
+2. 选择"火山引擎视频"Provider
+3. 修改第一个模型的 `模型ID` 为 `doubao-seedance-1-0-pro-260115`
+4. 显示名称自动变为：`豆包 Seedance Pro 260115`
+5. 点击"保存"
+
+**系统处理：**
+```javascript
+// API智能匹配逻辑
+const preset = VOLCANO_VIDEO_MODEL_PRESETS.find(p => 
+  p.modelId === 'doubao-seedance-1-0-pro-260115'
+);
+// ❌ 找不到精确匹配
+
+// 尝试模糊匹配
+const baseModelId = 'doubao-seedance-1-0';  // 提取基础名称
+const preset = VOLCANO_VIDEO_MODEL_PRESETS.find(p => 
+  p.modelId.startsWith(baseModelId)
+);
+// ✅ 找到：doubao-seedance-1-0-pro-250528
+
+// 使用旧版本的 capabilities 作为模板
+return {
+  ...preset,  // 继承 capabilities、defaultParams
+  modelId: 'doubao-seedance-1-0-pro-260115',  // 使用新版本ID
+  displayName: '豆包 Seedance Pro 260115',    // 管理员输入
+  description: '全功能专业版（2025年1月新版）' // 管理员输入
+};
+
+// ✅ 保存到数据库，前端功能正常使用
+```
+
+## 📝 后续维护步骤
+
+### 当火山引擎更新模型名称时：
+
+#### 方式1：管理员直接在UI中修改（推荐）
+1. 打开系统设置 → AI 模型
+2. 找到旧模型，点击"编辑"
+3. 修改模型ID和显示名称
+4. 保存即可
+
+#### 方式2：开发者更新预设配置（适用于批量更新）
+1. 修改 `lib/ai/volcano-video-models.ts` 文件
+2. 更新 `VOLCANO_VIDEO_MODEL_PRESETS` 数组中的模型配置
+3. 部署代码
+4. 管理员在UI中删除旧模型，重新添加（会自动使用新预设）
+
+## 🎯 关键优势
+
+✅ **灵活性**：管理员可以随时更新模型名称，无需代码改动  
+✅ **智能性**：API能自动匹配相似配置，避免配置丢失  
+✅ **一致性**：所有功能都从数据库读取，保证数据统一  
+✅ **可维护性**：预设配置集中管理，易于批量更新  
+
+## ⚠️ 注意事项
+
+1. **首次添加模型时**，必须选择火山引擎视频Provider，系统才会显示4个模型配置表单
+2. **模型ID必须唯一**，不能重复添加相同的模型
+3. **capabilities字段很重要**，决定了视频生成的参数验证逻辑
+4. **如果预设配置不匹配**，系统会使用Pro版本的默认配置作为兜底

+
+## 🔧 剩余集成步骤
+
+### 步骤 1：修改 MultimodalInput 组件
+
+**文件**：`components/multimodal-input.tsx`
+
+**需要修改的位置**：
+
+1. **添加状态管理**（在组件顶部添加）：
+```typescript
+// 在组件内部添加
+const [annotations, setAnnotations] = useState<Array<{
+  imageIndex: number;
+  description: string;
+  formattedText: string;
+}>>([]);
+
+// 添加标注处理函数
+const handleAnnotate = (annotation: {
+  imageIndex: number;
+  description: string;
+  formattedText: string;
+}) => {
+  setAnnotations((prev) => [...prev, annotation]);
+  
+  // 自动插入到输入框（在当前光标位置或末尾）
+  setInput((prev) => {
+    const currentValue = prev || "";
+    // 如果输入框有内容，在末尾添加空格
+    const separator = currentValue ? " " : "";
+    return `${currentValue}${separator}${annotation.formattedText}`;
+  });
+  
+  // 可选：添加视觉反馈
+  toast.success(`已添加标注：${annotation.description}`);
+};
+```
+
+2. **传递 props 到 PreviewAttachment**（找到渲染 PreviewAttachment 的地方）：
+```typescript
+// 在渲染 attachments 的地方修改
+{attachments.map((attachment, index) => (
+  <PreviewAttachment
+    key={attachment.url}
+    attachment={attachment}
+    isUploading={false}
+    onRemove={() => handleRemoveAttachment(attachment.url)}
+    onAnnotate={handleAnnotate}  // 新增
+    imageIndex={index + 1}         // 新增（从 1 开始编号）
+    draggable={attachments.length > 1}
+    onDragStart={(e) => handleDragStart(e, index)}
+    onDragEnd={handleDragEnd}
+    onDragOver={handleDragOver}
+    onDrop={(e) => handleDrop(e, index)}
+  />
+))}
+```
+
+---
+
+### 步骤 2：配置 Nginx 代理
+
+**文件**：`/etc/nginx/sites-available/ai-chatbot`（服务器上）
+
+**添加后端 API 代理**：
+```nginx
+# 在 server 块中添加
+location /api/detect-object {
+    proxy_pass http://127.0.0.1:8001/api/detect-object;
+    proxy_http_version 1.1;
+    proxy_set_header Upgrade $http_upgrade;
+    proxy_set_header Connection 'upgrade';
+    proxy_set_header Host $host;
+    proxy_cache_bypass $http_upgrade;
+    proxy_set_header X-Real-IP $remote_addr;
+    proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
+    
+    # 增加超时时间（AI 推理需要时间）
+    proxy_connect_timeout 10s;
+    proxy_send_timeout 10s;
+    proxy_read_timeout 10s;
+}
+```
+
+**应用配置**：
+```bash
+sudo nginx -t
+sudo systemctl reload nginx
+```
+
+---
+
+### 步骤 3：启动 Florence-2 API 服务
+
+等模型下载完成后（检查日志显示"✅ 模型下载完成"），执行：
+
+```bash
+# SSH 到服务器
+ssh -p 5204 root@156.225.27.52
+
+# 启动服务
+cd /var/www/ai-chatbot-backend
+pm2 start ecosystem.config.js
+
+# 查看日志
+pm2 logs florence-api
+
+# 检查状态
+pm2 status
+
+# 测试健康检查
+curl http://localhost:8001/health
+```
+
+**预期响应**：
+```json
+{"status":"ok","model_loaded":true}
+```
+
+---
+
+### 步骤 4：部署前端
+
+```bash
+# 本地构建并上传
+cd /Users/lanmu/Desktop/ai-chatbot-main
+npm run build
+pm2 restart ai-chatbot
+```
+
+或使用 SSH 直接在服务器上构建：
+```bash
+ssh -p 5204 root@156.225.27.52 "
+  cd /var/www/ai-chatbot && \
+  npm run build && \
+  pm2 restart ai-chatbot
+"
+```
+
+---
+
+### 步骤 5：测试功能
+
+1. **访问网站**：https://ai.yydd.ai
+
+2. **上传测试图片**：
+   - 选择图片生成模型
+   - 上传 2 张包含明显物体的图片
+
+3. **测试标注**：
+   - 点击第一张图片
+   - 点击"定位标注"按钮（Target 图标）
+   - 点击图片中的物体
+   - 等待识别结果
+   - 验证输入框中是否自动填入标注文本
+
+4. **预期结果**：
+   ```
+   输入框内容：📍图1: 绿色手提包
+   ```
+
+5. **继续测试第二张图**：
+   - 点击第二张图片，标注另一个物体
+   - 输入框应显示：`📍图1: 绿色手提包 📍图2: 红色背包`
+
+---
+
+## 🐛 常见问题排查
+
+### 问题 1：点击标注按钮无反应
+
+**检查**：
+1. 浏览器控制台是否有错误
+2. 后端 API 是否启动：`pm2 logs florence-api`
+3. Nginx 代理是否配置正确：`sudo nginx -t`
+
+### 问题 2：识别速度很慢
+
+**优化**：
+1. 确认使用 GPU：检查日志中是否显示"🚀 GPU 加速已启用"
+2. 检查 GPU 使用率：`nvidia-smi`
+3. 如果 GPU 未被使用，检查 CUDA_VISIBLE_DEVICES 环境变量
+
+### 问题 3：识别结果不准确
+
+**调整**：
+1. 提示用户点击物体中心位置
+2. 调整裁剪区域大小（florence_service.py 中的 crop_size）
+3. 尝试不同的提示词（CAPTION、DENSE_REGION_CAPTION 等）
+
+### 问题 4：502 Bad Gateway
+
+**检查**：
+1. 后端服务是否正常：`pm2 status`
+2. 查看后端日志：`pm2 logs florence-api --lines 50`
+3. 检查端口 8001 是否被占用：`lsof -i :8001`

+
+## 🎨 可选增强功能
+
+### 1. 标注文本样式
+
+在输入框中用特殊样式显示标注文本：
+
+```typescript
+// 可以添加一个组件来渲染标注标签
+const AnnotationTag = ({ text, onRemove }: { text: string; onRemove: () => void }) => (
+  <span className="inline-flex items-center gap-1 rounded-md bg-blue-500/10 px-2 py-1 text-blue-600">
+    <span>{text}</span>
+    <button onClick={onRemove} className="hover:text-blue-800">
+      ×
+    </button>
+  </span>
+);
+```
+
+### 2. 标注历史
+
+保存标注历史，允许用户重复使用：
+
+```typescript
+const [annotationHistory, setAnnotationHistory] = useLocalStorage<string[]>(
+  "annotation-history",
+  []
+);
+```
+
+### 3. 批量标注
+
+允许用户一次标注多个物体，然后一起插入：
+
+```typescript
+const [pendingAnnotations, setPendingAnnotations] = useState<Annotation[]>([]);
+
+const commitAnnotations = () => {
+  const text = pendingAnnotations.map(a => a.formattedText).join(" ");
+  setInput((prev) => `${prev} ${text}`);
+  setPendingAnnotations([]);
+};
+```

+
+### ⚠️ FRPC 穿透问题
+
+**问题**: 外部无法通过 `http://156.225.27.52:5245` 访问
+
+**可能原因**:
+1. FRP 服务器端未开放 5245 端口
+2. FRPC 配置中的 local_ip 或 local_port 不正确
+3. 防火墙阻止了连接
+
+## 解决方案
+
+### 方案 1: 检查 FRP 服务器配置
+
+需要在 FRP 服务器端（156.225.27.52）检查：
+- 是否开放了 5245 端口
+- FRP 服务器配置是否正确
+
+### 方案 2: 使用 Nginx 反向代理（推荐）
+
+如果 FRPC 穿透有问题，可以使用 Nginx 直接代理：
+
+```bash
+# 在服务器上配置 Nginx
+cat > /etc/nginx/sites-available/ai-chatbot << 'EOF'
+server {
+    listen 80;
+    server_name 156.225.27.52;
+
+    location / {
+        proxy_pass http://localhost:3001;
+        proxy_http_version 1.1;
+        proxy_set_header Upgrade $http_upgrade;
+        proxy_set_header Connection 'upgrade';
+        proxy_set_header Host $host;
+        proxy_set_header X-Real-IP $remote_addr;
+        proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
+        proxy_set_header X-Forwarded-Proto $scheme;
+        proxy_cache_bypass $http_upgrade;
+    }
+}
+EOF
+
+ln -sf /etc/nginx/sites-available/ai-chatbot /etc/nginx/sites-enabled/
+nginx -t && systemctl restart nginx
+```
+
+然后通过 `http://156.225.27.52` 访问。
+
+### 方案 3: 检查防火墙
+
+```bash
+# 检查防火墙规则
+ufw status
+iptables -L -n | grep 5245

+   # 复制公钥到服务器
+   ssh-copy-id -p 5204 root@156.225.27.52
+   ```
+
+2. **禁用 root 密码登录**（配置 SSH 密钥后）：
+   ```bash
+   # 编辑 SSH 配置
+   nano /etc/ssh/sshd_config
+   
+   # 设置
+   PasswordAuthentication no
+   PermitRootLogin prohibit-password
+   
+   # 重启 SSH
+   systemctl restart sshd
+   ```
+
+3. **配置 SSL 证书**（使用 Let's Encrypt）：
+   ```bash
+   apt install certbot python3-certbot-nginx -y
+   certbot --nginx -d your-domain.com
+   ```
+
+4. **定期更新系统**：
+   ```bash
+   apt update && apt upgrade -y
+   ```
+

+- ✅ 多组织切换
+- ✅ 自动创建用户
+- ✅ 用户信息同步
+
+---
+
+## 二、钉钉应用配置
+
+### 2.1 钉钉开放平台配置
+
+需要在钉钉开放平台创建应用，并获取以下信息：
+
+#### 应用类型
+- **H5微应用** 或 **第三方企业应用**
+
+#### 必需的配置参数
+```javascript
+{
+  clientId: 'dingxxxxxxxxxx',          // 应用的 AppKey/ClientId
+  clientSecret: 'xxxxxxxxxxxxxx',      // 应用的 AppSecret/ClientSecret
+  corpId: 'dingxxxxxxxxxx'             // 企业 CorpId（仅内部免密登录需要）
+}
+```
+
+#### 权限配置
+需要申请以下权限：
+- `Contact.User.Read` - 通讯录只读权限
+- `openid` - 获取用户OpenID
+
+#### 回调域名配置
+在钉钉开放平台配置以下回调地址：
+```
+http://your-domain.com/dingtalk-callback.html
+http://your-domain.com/dingtalk.html
+```
+
+### 2.2 项目中的配置
+
+#### 后端配置文件：`server/routes/dingtalk.js`
+
+```javascript
+// 钉钉应用配置
+const DINGTALK_CONFIG = {
+    test: {
+        clientId: 'dingmnpddoxnelhouyiq',
+        clientSecret: '9efbE4X-Nmk5rl21FZ3iGa6gQtQWXk4xMquy6Lmt2adN3OJQMBrCN_40DZg-6xPK',
+    },
+    jianshang: {

+        clientSecret: 'qUmj_gBDzpPEYR3RA3hRqKzwu11a986O-wKfP8V5lDHXn7XJrXxW79KIeP5G-mcY',
+    }
+};
+```
+
+> ⚠️ **安全提示**：生产环境应将这些配置移至环境变量 `.env` 文件中
+
+---
+
+## 三、数据库配置
+
+### 3.1 用户模型扩展
+
+在 `server/models/User.js` 中添加钉钉登录相关字段：
+
+```javascript
+const userSchema = new mongoose.Schema({
+  // ... 其他字段
+  
+  // 钉钉登录相关字段
+  dingtalk_userid: {
+    type: String,
+    sparse: true,      // 允许多个null值，但不允许重复的非null值
+    unique: true
+  },
+  loginType: {
+    type: String,
+    enum: ['normal', 'dingtalk'],
+    default: 'normal'
+  },
+  phone: {
+    type: String,
+    sparse: true,
+    unique: true
+  },
+  realName: {
+    type: String,
+    trim: true
+  },
+  isEmailVerified: {
+    type: Boolean,
+    default: false
+  }
+});
+```
+
+---
+
+## 四、后端路由配置
+
+### 4.1 主服务器配置
+
+在 `server/server.js` 中引入钉钉路由：
+
+```javascript
+// 导入钉钉登录路由
+const dingtalkRoutes = require('./routes/dingtalk');
+
+// 注册路由
+app.use('/api/dingtalk', dingtalkRoutes);
+```
+
+### 4.2 钉钉登录路由
+
+创建文件 `server/routes/dingtalk.js`，包含以下接口：
+
+#### 接口1：OAuth2验证接口
+```javascript
+GET /api/dingtalk/oauth2
+参数：
+  - code: 授权码
+  - company: 公司标识（默认mistong）
+```
+
+#### 接口2：钉钉登录接口
+```javascript
+POST /api/dingtalk/login
+请求体：
+{
+  "code": "授权码",
+  "state": "公司标识"
+}
+响应：
+{
+  "success": true,
+  "message": "登录成功",
+  "user": {...},
+  "token": "JWT令牌"
+}
+```
+
+#### 接口3：钉钉免密登录接口（用于钉钉内部）
+```javascript
+POST /api/dingtalk/autologin
+请求体：
+{
+  "code": "免登授权码",
+  "state": "公司标识"
+}
+```
+
+### 4.3 核心函数实现
+
+```javascript
+// 获取用户访问令牌
+async function getUserAccessToken(code, company) {
+    const config = DINGTALK_CONFIG[company];
+    const url = 'https://api.dingtalk.com/v1.0/oauth2/userAccessToken';
+    
+    const params = {
+        clientId: config.clientId,
+        clientSecret: config.clientSecret,
+        code: code,
+        grantType: 'authorization_code'
+    };
+    
+    const response = await axios.post(url, params, {
+        headers: { 'Content-Type': 'application/json' }
+    });
+    
+    return response.data;
+}
+
+// 获取应用访问令牌
+async function getAppAccessToken(company) {
+    const config = DINGTALK_CONFIG[company];
+    const url = 'https://oapi.dingtalk.com/gettoken';
+    
+    const response = await axios.get(url, {
+        params: {
+            appkey: config.clientId,
+            appsecret: config.clientSecret
+        }
+    });
+    
+    return response.data.access_token;
+}
+
+// 根据token获取用户unionId
+async function getUnionId(token) {
+    const url = 'https://api.dingtalk.com/v1.0/contact/users/me';
+    
+    const response = await axios.get(url, {
+        headers: { 'x-acs-dingtalk-access-token': token }
+    });
+    
+    return response.data.unionId;
+}
+
+// 根据unionId获取userId
+async function getUserIdByUnionId(unionId, appToken) {
+    const url = `https://oapi.dingtalk.com/topapi/user/getbyunionid?access_token=${appToken}`;
+    
+    const response = await axios.post(url, { unionid: unionId });
+    
+    return response.data.result.userid;
+}
+
+// 根据userId获取用户信息
+async function getUserInfo(userId, appToken) {
+    const url = `https://oapi.dingtalk.com/topapi/v2/user/get?access_token=${appToken}`;
+    
+    const response = await axios.post(url, { userid: userId });
+    
+    return response.data.result;
+}
+```
+
+---
+

+        // 跳转到首页
+        window.location.href = '/';
+    }
+});
+```
+
+### 5.2 钉钉回调页面
+
+#### 文件：`public/dingtalk-callback.html`
+
+这是钉钉OAuth2回调页面，处理授权码并完成登录：
+
+```javascript
+document.addEventListener('DOMContentLoaded', function() {
+    const urlParams = new URLSearchParams(window.location.search);
+    const code = urlParams.get('code');
+    const state = urlParams.get('state') || 'mistong';
+    
+    if (!code) {
+        showError('授权失败：缺少授权码');
+        return;
+    }
+    
+    // 调用登录接口
+    login(code, state);
+});
+
+async function login(code, company) {
+    try {
+        const response = await fetch('/api/dingtalk/login', {
+            method: 'POST',
+            headers: { 'Content-Type': 'application/json' },
+            body: JSON.stringify({ code, state: company }),
+            credentials: 'include'
+        });
+        
+        const data = await response.json();
+        
+        if (response.ok && data.success) {
+            // 保存登录状态
+            localStorage.setItem('isLoggedIn', 'true');
+            localStorage.setItem('username', data.user.username);
+            localStorage.setItem('token', data.token);
+            
+            // 通知父窗口登录成功
+            if (window.parent !== window) {
+                window.parent.postMessage({
+                    type: 'dingtalk_login_success',
+                    userInfo: data.user,
+                    token: data.token
+                }, '*');
+            } else {
+                window.location.href = '/';
+            }
+        } else {
+            throw new Error(data.message || '登录失败');
+        }
+    } catch (error) {
+        showError(error.message);
+    }
+}
+```
+
+### 5.3 钉钉内免密登录页面
+
+#### 文件：`public/dingtalk.html`
+
+用于在钉钉客户端内部实现免密登录：
+
+```html
+<script src="https://g.alicdn.com/dingding/dingtalk-jsapi/3.1.0/dingtalk.open.js"></script>
+
+<script>
+const isDingTalk = () => {
+    const ua = navigator.userAgent;
+    return ua.includes('DingTalk');
+};
+
+if (isDingTalk()) {
+    // 在钉钉中使用免登授权码
+    dd.ready(function () {
+        dd.runtime.permission.requestAuthCode({
+            corpId: "dingd590aa10d5b1efad35c2f4657eb6378f", // 企业id
+            onSuccess: function (info) {
+                const code = info.code;
+                window.open("/dingtalk.html?code=" + code);
+            }
+        });
+    });
+} else {
+    // 在外部浏览器中使用授权码登录
+    const urlParams = new URLSearchParams(window.location.search);
+    const code = urlParams.get('code');
+    const state = urlParams.get('state') || 'jianshang';
+    
+    login(code, state);
+}
+
+async function login(code, company) {
+    const response = await fetch('/api/dingtalk/autologin', {
+        method: 'POST',
+        headers: { 'Content-Type': 'application/json' },
+        body: JSON.stringify({ code, state: company }),
+        credentials: 'include'
+    });
+    
+    const data = await response.json();
+    
+    if (data.success) {
+        localStorage.setItem('isLoggedIn', 'true');
+        localStorage.setItem('token', data.token);
+        window.location.href = '/';
+    }
+}
+</script>
+```
+
+---
+
+## 六、环境变量配置
+
+在 `.env` 文件中添加以下配置：
+
+```env
+# JWT密钥（必需）
+JWT_SECRET=your_jwt_secret_key_here
+
+# 钉钉应用配置（可选，也可以在代码中配置）
+DINGTALK_TEST_CLIENT_ID=dingmnpddoxnelhouyiq
+DINGTALK_TEST_CLIENT_SECRET=your_secret_here
+
+DINGTALK_JIANSHANG_CLIENT_ID=ding1bs1gxwrcfu16x0f
+DINGTALK_JIANSHANG_CLIENT_SECRET=your_secret_here
+DINGTALK_JIANSHANG_CORP_ID=dingd590aa10d5b1efad35c2f4657eb6378f
+
+# 会话密钥
+SESSION_SECRET=your_session_secret_key_here
+
+# Node环境
+NODE_ENV=production
+```
+
+---
+
+## 七、依赖包
+
+需要安装以下npm包：
+
+```json
+{
+  "dependencies": {
+    "express": "^4.21.2",
+    "axios": "^1.8.4",
+    "jsonwebtoken": "^9.0.2",
+    "bcrypt": "^6.0.0",
+    "mongoose": "^6.13.8",
+    "cookie-parser": "^1.4.7",
+    "express-session": "^1.18.1",
+    "dotenv": "^16.4.7"
+  }
+}
+```
+
+安装命令：
+```bash
+npm install express axios jsonwebtoken bcrypt mongoose cookie-parser express-session dotenv
+```
+
+---
+
+## 八、完整登录流程
+
+### 8.1 Web扫码登录流程
+
+```mermaid
+sequenceDiagram
+    participant User as 用户
+    participant Web as Web页面
+    participant DT as 钉钉服务器
+    participant Backend as 后端服务器
+    participant DB as 数据库
+
+    User->>Web: 点击钉钉登录按钮
+    Web->>DT: 跳转到钉钉授权页面
+    User->>DT: 扫码授权
+    DT->>Web: 返回授权码(code)
+    Web->>Backend: POST /api/dingtalk/login {code, state}
+    Backend->>DT: 用授权码换取用户token
+    DT->>Backend: 返回access_token
+    Backend->>DT: 用token获取unionId
+    DT->>Backend: 返回unionId
+    Backend->>DT: 用unionId获取userId
+    DT->>Backend: 返回userId
+    Backend->>DT: 用userId获取用户详细信息
+    DT->>Backend: 返回用户信息
+    Backend->>DB: 查找或创建用户
+    DB->>Backend: 返回用户数据
+    Backend->>Web: 返回JWT token和用户信息
+    Web->>User: 登录成功，跳转首页
+```
+
+### 8.2 钉钉内免密登录流程
+
+```mermaid
+sequenceDiagram
+    participant User as 用户
+    participant DTClient as 钉钉客户端
+    participant Web as Web页面
+    participant Backend as 后端服务器
+    participant DB as 数据库
+
+    User->>DTClient: 在钉钉中打开应用
+    DTClient->>Web: 加载页面
+    Web->>DTClient: 调用dd.runtime.permission.requestAuthCode
+    DTClient->>Web: 返回免登授权码
+    Web->>Backend: POST /api/dingtalk/autologin {code, state}
+    Backend->>DTClient: 用免登码获取userId
+    Backend->>DTClient: 获取用户详细信息
+    Backend->>DB: 查找或创建用户
+    Backend->>Web: 返回JWT token
+    Web->>User: 自动登录成功
+```
+
+---
+
+## 九、关键代码说明
+
+### 9.1 用户创建逻辑
+
+当钉钉用户首次登录时，系统会自动创建账户：
+
+```javascript
+// 首先通过钉钉userid查找用户
+let user = await User.findOne({ dingtalk_userid: userId });
+
+if (!user) {
+    // 创建新用户
+    const randomPassword = generateRandomPassword(10);
+    const hashedPassword = await bcrypt.hash(randomPassword, 10);
+    
+    user = new User({
+        username: userInfo.job_number || userInfo.name,
+        email: userInfo.email || generateRandomEmail(),
+        password: hashedPassword,
+        realName: userInfo.name,
+        avatar: userInfo.avatar,
+        phone: userInfo.mobile || null,
+        role: 'user',
+        status: 'active',
+        isEmailVerified: true, // 钉钉用户默认已验证
+        loginType: 'dingtalk',
+        dingtalk_userid: userId
+    });
+    
+    await user.save();
+}
+```
+
+### 9.2 JWT Token生成
+
+```javascript
+// 生成JWT令牌
+const token = jwt.sign(
+    {
+        userId: user._id,
+        username: user.username,
+        role: user.role
+    },
+    process.env.JWT_SECRET || 'your-secret-key',
+    { expiresIn: '7d' }
+);
+
+// 设置cookie
+res.cookie('token', token, {
+    httpOnly: true,
+    secure: process.env.NODE_ENV === 'production',
+    maxAge: 7 * 24 * 60 * 60 * 1000 // 7天
+});
+```
+
+---
+
+## 十、安全建议
+
+### 10.1 配置安全
+- ✅ 将所有敏感配置（clientSecret等）移至环境变量
+- ✅ 不要将 `.env` 文件提交到版本控制
+- ✅ 使用强随机的JWT_SECRET
+
+### 10.2 传输安全
+- ✅ 生产环境使用HTTPS
+- ✅ 启用Cookie的secure标志
+- ✅ 使用httpOnly防止XSS攻击
+
+### 10.3 数据安全
+- ✅ 密码使用bcrypt加密
+- ✅ Token设置合理的过期时间
+- ✅ 定期清理过期的token
+

+
+## 十一、常见问题
+
+### Q1: 回调页面显示"授权失败：缺少授权码"
+**原因**：钉钉回调地址配置错误或未在钉钉开放平台配置
+**解决**：检查钉钉开放平台的回调地址配置
+
+### Q2: 登录后提示"获取用户信息失败"
+**原因**：应用权限不足
+**解决**：在钉钉开放平台检查是否已申请通讯录读取权限
+
+### Q3: 钉钉内免密登录失败
+**原因**：corpId配置错误
+**解决**：确认corpId是正确的企业ID
+
+### Q4: Token验证失败
+**原因**：JWT_SECRET配置不一致
+**解决**：确保所有服务使用相同的JWT_SECRET

+# 500 错误修复说明
+
+## 问题描述
+
+页面白屏，报错：
+```
+[Error] Failed to load resource: the server responded with a status of 500 (Internal Server Error) (guest, line 0)
+```
+
+## 根本原因
+
+数据库表 `User` 缺少新增的字段：
+- `role` (VARCHAR, 默认值: 'regular')
+- `isActive` (BOOLEAN, 默认值: true)
+- `createdAt` (TIMESTAMP, 默认值: NOW())
+- `updatedAt` (TIMESTAMP, 默认值: NOW())
+
+代码在 `createGuestUser()` 和 `authorize()` 函数中尝试访问这些字段，但数据库表中不存在，导致查询失败。
+
+## 修复步骤
+
+### 1. 添加缺失的数据库字段
+
+```sql
+ALTER TABLE "User" ADD COLUMN IF NOT EXISTS role VARCHAR DEFAULT 'regular' NOT NULL;
+ALTER TABLE "User" ADD COLUMN IF NOT EXISTS "isActive" BOOLEAN DEFAULT true NOT NULL;
+ALTER TABLE "User" ADD COLUMN IF NOT EXISTS "createdAt" TIMESTAMP DEFAULT NOW() NOT NULL;
+ALTER TABLE "User" ADD COLUMN IF NOT EXISTS "updatedAt" TIMESTAMP DEFAULT NOW() NOT NULL;
+```
+
+### 2. 运行数据库迁移
+
+```bash
+cd /var/www/ai-chatbot
+pnpm db:migrate
+```
+
+### 3. 重启应用
+
+```bash
+pm2 restart ai-chatbot
+```
+
+## 验证结果
+
+- ✅ 数据库字段已添加
+- ✅ 应用已重启
+- ✅ Guest 路由正常响应（返回重定向，这是预期行为）
+
+## 当前状态
+
+应用现在应该可以正常访问：
+- **本地访问**: `http://localhost:3001` ✅
+- **穿透访问**: `http://156.225.27.52:5245` ✅
+
+## 注意事项
+
+1. 所有现有用户需要更新，为它们设置默认的 `role` 和 `isActive` 值
+2. 如果还有其他数据库迁移未执行，需要运行 `pnpm db:migrate`
+
+## 后续建议
+
+1. 检查是否有其他数据库迁移未执行
+2. 为现有用户更新 `role` 和 `isActive` 字段
+3. 确保所有数据库迁移都已正确执行
+
