+}
+```
+
+### 3. HomePage 拆分
+
+#### useHomeState Hook
+```typescript
+// hooks/useHomeState.ts
+interface HomeState {
+  searchKeyword: string
+  selectedCategory: string
+  selectedScene: string
+  selectedMaterialType: string
+  selectedPlatform: string
+  selectedProductCategory: string
+  selectedMonth: string
+  sortBy: string
+  sortOrder: 'asc' | 'desc'
+  isFilterCollapsed: boolean
+}
+
+export function useHomeState(): {
+  state: HomeState
+  actions: HomeStateActions
+}
+```
+
+#### useMaterials Hook
+```typescript
+// hooks/useMaterials.ts
+interface UseMaterialsOptions {
+  searchKeyword: string
+  selectedCategory: string
+  selectedScene: string
+  selectedMaterialType: string
+  selectedPlatform: string
+  selectedProductCategory: string
+  selectedMonth: string

+  sortOrder: 'asc' | 'desc'
+}
+
+export function useMaterials(options: UseMaterialsOptions): {
+  materials: Material[]
+  loading: boolean
+  hasMore: boolean
+  totalCount: number
+  loadMore: () => Promise<void>
+  refresh: () => Promise<void>
+}
+```
+
+#### Home Components
+```typescript
+// components/home/FilterPanel.tsx
+interface FilterPanelProps {
+  categories: Category[]
+  scenes: Scene[]
+  platforms: Platform[]
+  productCategories: ProductCategory[]
+  materialTypes: MaterialType[]
+  months: Month[]
+  selectedCategory: string
+  selectedScene: string
+  selectedMaterialType: string
+  selectedPlatform: string
+  selectedProductCategory: string
+  selectedMonth: string
+  sortBy: string
+  sortOrder: 'asc' | 'desc'
+  isCollapsed: boolean
+  onCategoryChange: (value: string) => void
+  onSceneChange: (value: string) => void
+  onMaterialTypeChange: (value: string) => void
+  onPlatformChange: (value: string) => void
+  onProductCategoryChange: (value: string) => void
+  onMonthChange: (value: string) => void
+  onSortByChange: (value: string) => void
+  onSortOrderChange: (value: 'asc' | 'desc') => void
+  onToggleCollapse: () => void
+}
+
+// components/home/MaterialGrid.tsx
+interface MaterialGridProps {
+  materials: Material[]
+  loading: boolean
+  onMaterialClick: (material: Material) => void
+  onDownload: (material: Material) => void
+  onLike: (material: Material) => void
+  onFavorite: (material: Material) => void
+  onShare: (material: Material) => void
+}
+
+// components/home/SearchBar.tsx
+interface SearchBarProps {
+  value: string
+  onChange: (value: string) => void
+  placeholder?: string
+}
+
+// components/home/Pagination.tsx
+interface PaginationProps {
+  hasMore: boolean
+  isLoading: boolean
+  onLoadMore: () => void
+}
+```
+
+## Data Models
+
+数据模型保持不变，继续使用现有的 Prisma 模型和 TypeScript 接口。
+
+## Correctness Properties
+
+*A property is a characteristic or behavior that should hold true across all valid executions of a system-essentially, a formal statement about what the system should do. Properties serve as the bridge between human-readable specifications and machine-verifiable correctness guarantees.*
+
+由于本次重构主要是代码组织优化，不涉及业务逻辑变更，因此主要通过以下方式验证正确性：
+
+1. **构建验证**: 重构后代码能够成功通过 TypeScript 编译和 Next.js 构建
+2. **行数验证**: 主文件行数符合目标要求
+3. **功能验证**: 通过手动测试确保所有功能正常工作
+
+## Error Handling
+
+- 拆分后的 Hooks 和组件应保持原有的错误处理逻辑
+- 新增的 Hooks 应提供统一的错误状态和错误处理回调
+- 组件间通过 props 传递错误信息，保持错误边界清晰
+
+## Testing Strategy
+
+### 验证方式
+
+1. **TypeScript 类型检查**: 运行 `npx tsc --noEmit` 确保无类型错误
+2. **ESLint 检查**: 运行 `npm run lint` 确保代码风格一致
+3. **构建测试**: 运行 `npm run build` 确保能够成功构建
+4. **手动功能测试**: 
+   - 测试上传弹窗的所有上传类型
+   - 测试管理后台的所有功能标签页
+   - 测试首页的筛选、搜索、分页功能
+
+### 回归测试清单
+
+- [ ] 单个文件上传（各种素材类型）
+- [ ] 批量文件上传（音乐、视频、3D场景等）
+- [ ] 拖拽上传
+- [ ] 分类/场景/平台筛选
+- [ ] 搜索功能
+- [ ] 分页加载
+- [ ] 用户管理
+- [ ] 素材管理（删除、恢复）
+- [ ] 分类管理（增删改）

+
+### UploadModal 拆分说明
+UploadModal 目标行数 < 500 行未达成，原因：
+1. **复杂的业务逻辑**: 支持 15+ 种素材类型，每种类型有不同的上传流程
+2. **多种上传模式**: 单文件、批量文件、特殊类型批量（音乐/视频/买家秀等）
+3. **状态耦合**: 上传进度、拖拽状态、表单验证等状态紧密关联
+4. **风险考量**: 进一步拆分可能引入回归问题，当前代码已稳定运行
+
+已完成的优化：
+- 删除 260 行死代码
+- 提取 UI 组件（UploadForm、SpecialBatchUploadUI、BatchFileList 等）
+- 提取数据获取逻辑（useCategoryData）
+- 创建备用 hooks 供未来使用
+
+### 首页拆分说明
+首页目标行数 < 300 行未达成，原因：
+- 首页包含大量业务逻辑（转码轮询、音频播放、分类数据获取等）
+- 这些逻辑与 UI 紧密耦合，进一步拆分需要更大的重构工作
+- 当前重构已显著提升代码可维护性

+## 用户偏好
+
+- 能用中文就用中文（文档、注释）
+- 不写不重要的文档
+- 不喜欢垃圾文件、残留文件
+- **修复原则**: 优先找到问题根源彻底解决，不要打补丁（除非不得已）
+

+
+Next.js 14 + React 18 + TypeScript + TailwindCSS + Prisma + PostgreSQL + MinIO S3 + NextAuth + 钉钉登录
+
+处理库：FFmpeg（视频）、Sharp（图片）、music-metadata（音频）、ag-psd（PSD）
+

+## ⚠️ 新老素材存储（核心）
+
+**分界点：2025-10-27**
+
+| 项目 | 老素材 | 新素材 |
+|------|--------|--------|
+| S3 | `s3.1080p.hk/jsxiangche` | `s3.yydd.ai/gongxiangpan/由壹点AI/` |
+| 识别 | `previewUrl`不含`由壹点AI/` | `previewUrl`含`由壹点AI/` |
+
+**原则**: 不改老素材 | 视频/音频存本地（MinIO机械盘慢）| 下载兼容新老路径
+
+---
+
+## 关键文件
+
+- 上传: `components/UploadModal.tsx`、`components/upload/`
+- API: `app/api/materials/upload/`（含init/chunk/complete）、`download/`、`transcode/`
+- Lib: `lib/s3.ts`、`lib/video-processor.ts`、`lib/url-rewrite.ts`
+
+---
+
+## 文件命名
+
+- 视频: `video-{ts}-{hash}.mp4`（不是video-source）
+- 音频: `audio-source-{id}-{ts}.mp3`
+- 其他: `material-{ts}-{hash}.zip`
+
+---
+
+## 要点
+
+- **分片上传**: >5MB自动启用，IndexedDB断点续传
+- **视频转码**: 自动触发，720P预览+10秒片段+封面，状态`pending→processing→done/failed`
+- **图片**: 预览图压缩800×2000，展示图>1500px自动切片
+- **数据库**: 所有查询必须 `deletedAt: null`
+
+---
+
+## 操作规范
+
+1. 数据库修改前必须备份
+2. 部署默认正式系统，明确要求才部署影子
+3. uploads目录不可删除
+
+**部署**: `.\deploy-local-build.ps1`（影子加 `-Target shadow`）
+
+---
+
+## 忽略目录
+
+`flnxi_sucai/`、`gongxiangp2/`（子目录）- 仅参考，不要使用

+- 应用可能响应太慢导致超时
+
+---
+
+## 🛠️ 建议的检查步骤
+
+### 步骤 1: 检查穿透服务器上的 nginx 配置
+```bash
+# 需要 SSH 到 180.97.221.140
+ssh root@180.97.221.140
+
+# 检查 nginx 状态
+systemctl status nginx
+
+# 检查 nginx 配置
+nginx -t
+cat /etc/nginx/sites-enabled/* | grep -A 20 "youyidian\|2320"
+
+# 检查 nginx 错误日志
+tail -50 /var/log/nginx/error.log
+```
+
+### 步骤 2: 检查 frps 服务状态
+```bash
+# 在穿透服务器上
+systemctl status frps
+ps aux | grep frps
+netstat -tlnp | grep 2320
+```
+
+### 步骤 3: 测试 frp 隧道连接
+```bash
+# 在正式环境服务器上测试
+curl -v http://127.0.0.1:4320/api/health
+
+# 检查 frpc 日志中是否有 youyidian-3d 相关的错误
+grep "youyidian-3d" /root/frp/frpc.log
+```
+
+### 步骤 4: 检查防火墙规则
+```bash
+# 在穿透服务器上
+iptables -L -n | grep 2320
+firewall-cmd --list-all  # 如果使用 firewalld
+```
+
+---
+
+## 🚀 快速修复建议
+
+### 方案 1: 重启 nginx（如果 nginx 配置正确）
+```bash
+ssh root@180.97.221.140
+systemctl restart nginx
+systemctl status nginx
+```
+
+### 方案 2: 重启 frps 服务
+```bash
+ssh root@180.97.221.140
+systemctl restart frps
+systemctl status frps
+```
+
+### 方案 3: 重启 frpc 客户端
+```bash
+ssh root@192.168.58.20
+systemctl restart frpc  # 如果有 systemd 服务
+# 或者
+pkill frpc
+# 然后重新启动 frpc
+```
+
+### 方案 4: 检查并修复 nginx 配置
+如果 nginx 配置有问题，需要：
+1. 确认 nginx 配置中 upstream 指向 `127.0.0.1:2320`
+2. 确认 server_name 配置正确
+3. 确认 proxy_pass 配置正确

+## 🔴 问题根本原因（已确认）
+
+### ✅ 重要澄清：两个 FRPC 进程各司其职
+
+**发现**：有两个 frpc 进程，但它们有不同的用途，不会冲突！
+
+**进程 1: PID 4747** (Systemd 管理)
+- 用途: 3D素材系统 (youyidian-3d)
+- 配置文件: `/etc/frp/frpc.toml`
+- FRPS 服务器: `180.97.221.140:7000`
+- 连接状态: ✅ 已建立连接
+
+**进程 2: PID 9990** (Docker 容器 `frpc-minio`)
+- 用途: MinIO 服务
+- 配置文件: `/mnt/tank/apps/frp-minio/frpc.toml` (挂载到容器内)
+- FRPS 服务器: `103.118.245.6:7001` (不同的服务器！)
+- 连接状态: ✅ 已建立连接
+
+**结论**: 两个进程配置正确，连接到不同的服务器，**不会冲突**。
+
+### 🔴 核心问题：FRP 工作连接超时
+
+从 frps 日志中发现关键错误：
+```
+[W] [server/control.go:289] timeout trying to get work connection
+[W] [proxy/proxy.go:128] [youyidian-3d] failed to get work connection: timeout trying to get work connection
+```
+
+**问题分析**：
+1. ✅ FRP 控制连接已建立（frpc ↔ frps 端口 7000）
+2. ✅ FRP 代理配置正确（youyidian-3d: 127.0.0.1:4320 → 2320）
+3. ✅ 端口 2320 正在监听
+4. ❌ **FRP 工作连接无法建立**（由于进程冲突导致）
+
+### 错误链条
+
+1. **用户请求** → nginx (443端口)
+2. **nginx** → frps (127.0.0.1:2320)
+3. **frps** 尝试建立工作连接到 **frpc**
+4. **frpc 无法响应工作连接请求** → 超时
+5. **nginx 收到连接重置** → 502 Bad Gateway
+
+### 从日志证据
+
+**frps 日志** (`/var/log/frps.log`):
+- 频繁出现 `timeout trying to get work connection`
+- `[youyidian-3d] failed to get work connection`
+
+**nginx 错误日志**:
+- `recv() failed (104: Connection reset by peer) while reading response header from upstream`
+- 所有请求都指向 `http://127.0.0.1:2320/api/rankings`
+
+---
+
+## 🛠️ 解决方案
+
+### 方案 1: 重启 frpc 客户端（推荐，最简单）
+
+**注意**: 两个 frpc 进程都有各自的用途，不需要停止任何一个。
+
+在正式环境服务器 (192.168.58.20) 上执行：
+
+```bash
+# 1. 重启 3D素材系统的 frpc (PID 4747)
+systemctl restart frpc
+
+# 2. 验证进程重启成功
+systemctl status frpc
+ps aux | grep frpc
+
+# 3. 等待几秒后，检查连接是否恢复
+netstat -an | grep 180.97.221.140:7000
+```
+
+### 方案 2: 检查 frpc 客户端配置
+
+确认 `/etc/frp/frpc.toml` 配置正确：
+- ✅ serverAddr = "180.97.221.140"
+- ✅ serverPort = 7000
+- ✅ auth.token 正确
+- ✅ youyidian-3d 代理配置正确
+
+### 方案 3: 检查网络连接
+
+在正式环境服务器上检查：
+```bash
+# 检查到 frps 的连接
+netstat -an | grep 180.97.221.140:7000
+
+# 检查本地应用是否正常
+curl -v http://127.0.0.1:4320/api/health
+```
+
+### 方案 4: 检查 frpc 日志
+
+查看 frpc 客户端日志，寻找错误信息：
+```bash
+tail -100 /root/frp/frpc.log | grep -i "error\|fail\|timeout\|youyidian"
+```
+
+---
+

+ssh root@180.97.221.140 "tail -20 /var/log/frps.log | grep youyidian"
+
+# 5. 测试网站是否可以访问
+curl -I https://3d.yydd.ai
+```
+
+**修复后，502 错误应该会消失。**
+
+---
+
+## ✅ 问题已解决（2025-12-29 15:45）
+
+### 执行的操作
+1. ✅ **重启 frpc 服务**: `systemctl restart frpc`
+   - 旧进程 PID: 3940107 (运行了5小时43分钟)
+   - 新进程 PID: 4159802 (重启后立即建立连接)
+
+2. ✅ **验证连接状态**:
+   - FRP 控制连接: ✅ 已建立 (192.168.58.20:41002 → 180.97.221.140:7000)
+   - 本地应用健康检查: ✅ HTTP 200 正常
+   - frpc 日志: ✅ 无错误信息

+# FRP 稳定性问题分析报告
+
+**检查时间**: 2025-12-29  
+**问题**: FRP穿透服务在短短几天内崩溃3次  
+**FRP版本**: 0.52.3
+
+---
+
+## 🔴 发现的问题
+
+### 1. Systemd 重启策略不够积极 ⚠️
+
+**当前配置**:
+```ini
+Restart=on-failure
+RestartSec=5s
+```
+
+**问题**:
+- `on-failure` 只在进程异常退出时重启
+- 如果FRP工作连接失败但进程未退出，systemd不会重启
+- 工作连接超时不会触发进程退出，导致服务"假死"
+
+**影响**: 服务看起来在运行，但实际无法建立工作连接
+
+---
+
+### 2. 连接池配置可能不足 ⚠️
+
+**当前配置**:
+```toml
+transport.poolCount = 5
+transport.heartbeatInterval = 30
+transport.heartbeatTimeout = 90
+```
+
+**问题**:
+- `poolCount = 5` 可能在高并发时不够
+- 工作连接池耗尽后，新请求会超时
+- 没有自动清理失效连接的机制
+
+**影响**: 高负载时工作连接池耗尽，导致502错误
+
+---
+
+### 3. 文件描述符限制过低 🔴
+
+**当前限制**: `ulimit -n = 1024`
+
+**问题**:
+- 网络服务需要大量文件描述符（每个连接一个）
+- 1024的限制可能导致连接数达到上限后无法建立新连接
+- FRP需要维护多个连接（控制连接 + 工作连接池）
+
+**影响**: 连接数达到上限后，新连接无法建立
+
+---
+
+### 4. CPU消耗异常高 ⚠️
+
+**观察数据**:
+- 运行约5小时43分钟，消耗CPU时间17分30秒
+- 运行更长时间后，消耗CPU时间40分27秒
+- CPU使用率14.4%（仅运行2分43秒）
+
+**问题**:
+- CPU消耗过高，可能是连接重试循环或资源泄漏
+- 高CPU使用可能导致响应变慢，触发超时
+
+**影响**: 性能下降，可能导致连接超时
+
+---
+
+### 5. 缺少监控和自动恢复机制 ⚠️
+
+**当前状态**:
+- 没有健康检查机制
+- 没有自动检测工作连接失败的机制
+- 依赖手动重启
+
+**影响**: 问题发现不及时，需要人工干预
+
+---
+
+## 📊 崩溃时间线
+
+根据日志分析：
+
+1. **第一次崩溃**: 约在 12月29日 10:01:33 之前
+   - 运行时间: 未知（可能是几天）
+   - CPU消耗: 40分27秒
+   - 手动重启
+
+2. **第二次崩溃**: 12月29日 15:45:33
+   - 运行时间: 约5小时43分钟
+   - CPU消耗: 17分30秒
+   - 手动重启
+
+3. **第三次崩溃**: 今天（用户报告）
+   - 运行时间: 约2小时
+   - CPU消耗: 23.649秒（仅2分43秒运行时间）
+
+**模式**: 崩溃间隔越来越短，说明问题在恶化
+
+---
+
+## 🛠️ 解决方案
+
+### 方案 1: 优化 Systemd 服务配置（立即执行）
+
+**修改 `/etc/systemd/system/frpc.service`**:
+
+```ini
+[Unit]
+Description=Frp Client Service
+After=network.target
+
+[Service]
+Type=simple
+# 改为 always，即使正常退出也重启（防止假死）
+Restart=always
+RestartSec=10s
+# 增加启动超时
+TimeoutStartSec=30s
+# 增加文件描述符限制
+LimitNOFILE=4096
+# 内存限制（防止内存泄漏）
+MemoryLimit=512M
+# CPU限制（防止CPU占用过高）
+CPUQuota=50%
+
+ExecStart=/root/gongxiangp2/frp_0.52.3_linux_amd64/frpc -c /etc/frp/frpc.toml
+StandardOutput=append:/root/frp/frpc.log
+StandardError=append:/root/frp/frpc.log
+
+[Install]
+WantedBy=multi-user.target
+```
+
+**关键改进**:
+- `Restart=always`: 即使正常退出也重启，防止假死
+- `LimitNOFILE=4096`: 增加文件描述符限制
+- `MemoryLimit=512M`: 防止内存泄漏
+- `CPUQuota=50%`: 限制CPU使用，防止占用过高
+
+---
+
+### 方案 2: 优化 FRP 客户端配置
+
+**修改 `/etc/frp/frpc.toml`**:
+
+```toml
+serverAddr = "180.97.221.140"
+serverPort = 7000
+
+auth.method = "token"
+auth.token = "LiuYunKu_NAS_2024_SecureToken"
+

+transport.tcpMux = true
+# 增加连接池大小（从5增加到10）

+# 增加健康检查
+healthCheck.type = "tcp"
+healthCheck.intervalSeconds = 10
+healthCheck.maxFailed = 3
+healthCheck.timeoutSeconds = 3
+```
+
+**关键改进**:
+- `poolCount = 10`: 增加连接池大小
+- `tcpKeepAlive = true`: 启用TCP保活
+- 添加健康检查配置（如果FRP版本支持）
+
+---
+
+### 方案 3: 添加健康检查和自动恢复脚本
+
+**创建健康检查脚本 `/root/frp/check-frpc-health.sh`**:
+
+```bash
+#!/bin/bash
+
+# FRP健康检查脚本
+# 检查工作连接是否正常
+
+FRPC_LOG="/root/frp/frpc.log"
+FRPC_SERVICE="frpc.service"
+CHECK_INTERVAL=60  # 每60秒检查一次
+MAX_FAILURES=3     # 连续失败3次后重启
+
+failure_count=0
+
+while true; do
+    # 检查frpc进程是否运行
+    if ! systemctl is-active --quiet $FRPC_SERVICE; then
+        echo "$(date): FRPC服务未运行，重启中..."
+        systemctl restart $FRPC_SERVICE
+        failure_count=0
+        sleep 10
+        continue
+    fi
+    
+    # 检查是否有工作连接超时错误（最近5分钟）
+    recent_errors=$(tail -100 "$FRPC_LOG" | grep -c "timeout trying to get work connection" || true)
+    
+    if [ "$recent_errors" -gt 5 ]; then
+        failure_count=$((failure_count + 1))
+        echo "$(date): 检测到工作连接超时错误 ($recent_errors次)，失败计数: $failure_count"
+        
+        if [ "$failure_count" -ge "$MAX_FAILURES" ]; then
+            echo "$(date): 连续失败达到上限，重启FRPC服务..."
+            systemctl restart $FRPC_SERVICE
+            failure_count=0
+        fi
+    else
+        failure_count=0
+    fi
+    
+    sleep $CHECK_INTERVAL
+done
+```
+
+**创建systemd定时器 `/etc/systemd/system/frpc-health-check.service`**:
+
+```ini
+[Unit]
+Description=FRPC Health Check Service
+After=network.target
+
+[Service]
+Type=simple
+ExecStart=/root/frp/check-frpc-health.sh
+Restart=always
+RestartSec=10s
+
+[Install]
+WantedBy=multi-user.target
+```
+
+---
+
+### 方案 4: 检查并优化系统资源
+
+**增加系统文件描述符限制**:
+
+```bash
+# 编辑 /etc/security/limits.conf
+echo "* soft nofile 4096" >> /etc/security/limits.conf
+echo "* hard nofile 8192" >> /etc/security/limits.conf
+
+# 编辑 /etc/systemd/system.conf
+# 取消注释并修改:
+# DefaultLimitNOFILE=4096:8192
+```
+
+---
+
+## 🎯 立即执行的操作
+
+### 步骤 1: 优化 Systemd 配置
+
+```bash
+ssh root@192.168.58.20
+
+# 备份当前配置
+cp /etc/systemd/system/frpc.service /etc/systemd/system/frpc.service.bak
+
+# 创建新配置（使用上面的优化配置）
+# ... (编辑文件)
+
+# 重新加载systemd配置
+systemctl daemon-reload
+
+# 重启服务
+systemctl restart frpc
+
+# 检查状态
+systemctl status frpc
+```
+
+### 步骤 2: 优化 FRP 配置
+
+```bash
+# 备份当前配置
+cp /etc/frp/frpc.toml /etc/frp/frpc.toml.bak
+
+# 修改配置（增加poolCount等）
+# ... (编辑文件)
+
+# 重启服务
+systemctl restart frpc
+```
+
+### 步骤 3: 增加文件描述符限制
+
+```bash
+# 临时增加（立即生效）
+ulimit -n 4096
+
+# 永久增加（需要编辑配置文件）
+# ... (编辑 /etc/security/limits.conf)
+```
+
+---
+
+## 📈 预期效果
+
+1. **稳定性提升**: `Restart=always` 确保服务始终运行
+2. **性能提升**: 增加连接池和文件描述符限制，支持更多并发
+3. **自动恢复**: 健康检查脚本自动检测并恢复问题
+4. **资源控制**: CPU和内存限制防止资源耗尽
+
+---
+
+## 🔍 后续监控
+
+建议监控以下指标：
+
+1. **服务运行时间**: `systemctl status frpc | grep Active`
+2. **CPU使用率**: `top -p $(pgrep frpc)`
+3. **内存使用**: `ps aux | grep frpc`
+4. **连接数**: `netstat -an | grep 180.97.221.140:7000 | wc -l`
+5. **错误日志**: `tail -f /root/frp/frpc.log | grep -E 'error|fail|timeout'`
+
+---
+
+## 📝 总结
+
+**根本原因**:
+1. Systemd重启策略不够积极（`on-failure` vs `always`）
+2. 连接池配置不足（`poolCount=5`）
+3. 文件描述符限制过低（1024）
+4. 缺少自动恢复机制
+
+**解决方案优先级**:
+1. 🔴 **高优先级**: 优化Systemd配置（`Restart=always` + 资源限制）
+2. 🟡 **中优先级**: 优化FRP配置（增加连接池）
+3. 🟢 **低优先级**: 添加健康检查脚本（可选，但推荐）
+
+**预计修复后稳定性**: 从几天崩溃一次 → 稳定运行数周/数月
+

+# 组织架构与用户管理设计方案
+
+## 📋 设计目标
+
+1. **清晰的层级结构**：支持多级部门、灵活的权限继承
+2. **完善的权限体系**：基于角色的访问控制（RBAC）
+3. **用户生命周期管理**：从注册到离职的完整流程
+4. **可扩展性**：支持未来组织架构变化
+5. **安全性**：权限审计、操作日志、数据隔离
+
+---
+
+## 🏗️ 一、组织架构设计
+
+### 1.1 组织架构层级模型
+
+```
+公司
+  └── 一级部门（如：设计部、市场部）
+      └── 二级部门（如：设计部-3D组、设计部-平面组）
+          └── 三级部门（可选，如：3D组-场景组）
+```
+
+**设计要点：**
+- **扁平化优先**：建议最多3级，避免过度复杂
+- **部门编码**：每个部门有唯一编码（如：`DEPT-001`），便于引用和迁移
+- **部门状态**：启用/禁用/归档（历史部门保留数据但不可用）
+- **部门负责人**：每个部门可设置1个负责人（部门管理员）
+
+### 1.2 数据模型设计
+
+```prisma
+model Department {
+  id          String   @id @default(uuid())
+  code        String   @unique // 部门编码，如：DEPT-001
+  name        String   // 部门名称
+  parentId    String?  // 父部门ID（支持层级结构）
+  parent      Department? @relation("DepartmentHierarchy", fields: [parentId], references: [id])
+  children    Department[] @relation("DepartmentHierarchy")
+  
+  level       Int      @default(1) // 层级：1=一级部门，2=二级部门，3=三级部门
+  managerId   String?  // 部门负责人ID
+  manager     User?    @relation("DepartmentManager", fields: [managerId], references: [id])
+  
+  status      String   @default("active") // active/disabled/archived
+  description String?  // 部门描述
+  sortOrder   Int      @default(0) // 排序
+  
+  createdAt   DateTime @default(now())
+  updatedAt   DateTime @updatedAt
+  
+  users       User[]
+  permissions DepartmentMaterialPermission[]
+  
+  @@index([parentId])
+  @@index([status])
+  @@map("departments")
+}
+```
+
+**关键设计决策：**
+- ✅ **自关联表**：使用 `parentId` 实现树形结构，查询灵活
+- ✅ **部门编码**：唯一标识，即使部门改名也不影响关联
+- ✅ **层级字段**：冗余存储层级，避免递归查询
+- ✅ **状态管理**：支持禁用和归档，保留历史数据
+
+---
+
+## 👥 二、用户角色权限体系（RBAC）
+
+### 2.1 角色体系设计
+
+```
+角色层级（权限从高到低）：
+1. 超级管理员（Super Admin）
+   - 所有权限
+   - 系统配置管理
+   - 用户和部门管理
+   - 最多4个（安全限制）
+
+2. 系统管理员（System Admin）
+   - 用户管理（本部门及下级部门）
+   - 部门权限配置
+   - 素材审核和管理
+   - 系统监控
+
+3. 部门管理员（Department Admin）
+   - 本部门用户管理
+   - 本部门权限配置
+   - 本部门素材审核
+
+4. 普通用户（User）
+   - 素材上传
+   - 素材查看/下载（受权限控制）
+   - 个人资料管理
+```
+
+### 2.2 权限矩阵
+
+| 功能 | 超级管理员 | 系统管理员 | 部门管理员 | 普通用户 |
+|------|----------|----------|----------|---------|
+| 系统设置 | ✅ | ❌ | ❌ | ❌ |
+| 用户管理（全部） | ✅ | ✅ | ❌ | ❌ |
+| 用户管理（本部门） | ✅ | ✅ | ✅ | ❌ |
+| 部门管理 | ✅ | ✅ | ❌ | ❌ |
+| 部门权限配置 | ✅ | ✅ | ✅（本部门） | ❌ |
+| 素材审核 | ✅ | ✅ | ✅（本部门） | ❌ |
+| 素材上传 | ✅ | ✅ | ✅ | ✅ |
+| 素材查看/下载 | ✅ | ✅（受权限） | ✅（受权限） | ✅（受权限） |
+| 素材编辑（他人） | ✅ | ✅ | ✅（本部门） | ❌ |
+| 素材删除 | ✅ | ✅ | ✅（本部门） | ❌（仅自己） |
+
+### 2.3 数据模型优化
+
+```prisma
+enum Role {
+  USER           // 普通用户
+  DEPT_ADMIN     // 部门管理员
+  SYSTEM_ADMIN   // 系统管理员
+  SUPER_ADMIN    // 超级管理员（保留 isSuperAdmin 字段作为额外标识）
+}
+
+model User {
+  id                String      @id @default(uuid())
+  email             String      @unique
+  username          String      @unique
+  password          String
+  realName          String?     // 真实姓名
+  phone             String?     @unique
+  avatar            String?
+  
+  // 组织架构
+  departmentId      String?     // 所属部门ID（外键关联）
+  department        Department? @relation(fields: [departmentId], references: [id])
+  
+  // 角色权限
+  role              Role        @default(USER)
+  isSuperAdmin      Boolean     @default(false) // 超级管理员标识（最多4个）
+  
+  // 用户状态
+  isActive          Boolean     @default(false) // 是否激活（默认未激活，需管理员激活）
+  canDownload      Boolean     @default(true)  // 是否允许下载（可单独控制）
+  status            String      @default("pending") // pending/active/suspended/archived
+  
+  // 钉钉集成
+  dingtalkUserId    String?     @unique
+  loginType         String      @default("normal") // normal/dingtalk
+  
+  // 审计字段
+  lastLoginAt       DateTime?
+  lastLoginIp       String?
+  loginCount        Int         @default(0)
+  createdAt         DateTime    @default(now())
+  updatedAt         DateTime    @updatedAt
+  archivedAt        DateTime?  // 归档时间（软删除）
+  
+  // 关联数据
+  materials         Material[]
+  likes             MaterialLike[]
+  favorites         MaterialFavorite[]
+  downloadLogs      MaterialDownloadLog[]
+  materialLogs      MaterialLog[]
+  operationLogs     UserOperationLog[] // 用户操作日志
+  
+  @@index([departmentId])
+  @@index([role])
+  @@index([status])
+  @@index([isActive])
+  @@map("users")
+}
+```
+
+**关键改进：**
+- ✅ **外键关联**：`departmentId` 替代字符串 `department`，数据一致性更好
+- ✅ **角色枚举**：明确的角色定义，避免字符串混乱
+- ✅ **状态管理**：`status` 字段管理用户生命周期
+- ✅ **审计字段**：记录登录信息，便于安全审计
+
+---
+
+## 🔐 三、权限管理设计
+
+### 3.1 权限继承机制
+
+```
+权限继承规则：
+1. 子部门默认继承父部门权限（可覆盖）
+2. 部门管理员可管理本部门及所有子部门
+3. 用户权限 = 个人权限 + 部门权限（取并集）
+```
+
+### 3.2 部门权限配置优化
+
+```prisma
+model DepartmentMaterialPermission {
+  id                 String    @id @default(uuid())
+  departmentId       String    // 部门ID（外键）
+  department         Department @relation(fields: [departmentId], references: [id])
+  materialType       String    // 素材类型
+  
+  // 权限配置
+  canView            Boolean   @default(false)
+  canDownload        Boolean   @default(false)
+  canShare           Boolean   @default(true)
+  canUpload          Boolean   @default(true) // 新增：是否允许上传
+  
+  // 权限继承
+  inheritFromParent  Boolean   @default(true) // 是否继承父部门权限
+  parentPermissionId String?   // 继承的父权限ID
+  
+  // 权限覆盖
+  isOverride         Boolean   @default(false) // 是否覆盖父部门权限
+  
+  createdAt          DateTime  @default(now())
+  updatedAt          DateTime  @updatedAt
+  
+  @@unique([departmentId, materialType])
+  @@index([departmentId])
+  @@index([materialType])
+  @@map("department_material_permissions")
+}
+```
+
+**设计要点：**
+- ✅ **外键关联**：使用 `departmentId` 替代字符串，支持级联删除
+- ✅ **权限继承**：`inheritFromParent` 控制是否继承父部门权限
+- ✅ **权限覆盖**：`isOverride` 允许子部门覆盖父部门权限
+- ✅ **上传权限**：新增 `canUpload`，控制部门上传权限
+
+---
+
+## 📊 四、用户生命周期管理
+
+### 4.1 用户状态流转
+
+```
+pending（待激活）
+  ↓ [管理员激活]
+active（正常）
+  ↓ [管理员暂停]
+suspended（暂停）
+  ↓ [管理员恢复]
+active（正常）
+  ↓ [离职/删除]
+archived（归档）
+```
+
+### 4.2 用户状态说明
+
+| 状态 | 说明 | 可登录 | 可操作 | 数据保留 |
+|------|------|--------|--------|----------|
+| `pending` | 新注册，待激活 | ❌ | ❌ | ✅ |
+| `active` | 正常使用 | ✅ | ✅ | ✅ |
+| `suspended` | 暂停使用 | ❌ | ❌ | ✅ |
+| `archived` | 已归档（离职） | ❌ | ❌ | ✅（只读） |
+
+### 4.3 用户管理流程
+
+**1. 新用户注册（钉钉登录）**
+```
+用户钉钉扫码登录
+  → 系统检查是否存在（通过 dingtalkUserId）
+  → 不存在：创建新用户（status=pending, isActive=false）
+  → 存在：检查 isActive
+    → false：提示"账号未激活，请联系管理员"
+    → true：正常登录
+```
+
+**2. 用户激活流程**
+```
+管理员在后台查看待激活用户列表
+  → 选择用户，设置部门、角色
+  → 激活账号（isActive=true, status=active）
+  → 系统自动创建该部门的默认权限配置
+  → 用户可正常登录使用
+```
+
+**3. 用户离职流程**
+```
+管理员标记用户为"已离职"
+  → status=archived, archivedAt=now()
+  → isActive=false
+  → 用户无法登录
+  → 用户上传的素材保留（标记原用户）
+  → 操作日志保留（审计需要）
+```
+
+---
+
+## 🔍 五、用户搜索与查询优化
+
+### 5.1 多维度搜索
+
+```typescript
+// 搜索字段
+- 用户名（username）
+- 真实姓名（realName）
+- 邮箱（email）
+- 手机号（phone）
+- 部门名称（通过 departmentId 关联查询）
+- 钉钉用户ID（dingtalkUserId）
+
+// 筛选条件
+- 角色（role）
+- 状态（status）
+- 是否激活（isActive）
+- 部门（departmentId）
+- 注册时间范围
+- 最后登录时间范围
+```
+
+### 5.2 用户列表展示优化
+
+**树形结构展示：**
+```
+部门A
+  ├── 管理员：张三
+  └── 用户
+      ├── 李四
+      └── 王五
+部门B
+  ├── 管理员：赵六
+  └── 用户
+      └── 孙七
+```
+
+**扁平列表展示：**
+- 支持按部门、角色、状态筛选
+- 支持多字段搜索
+- 支持排序（注册时间、最后登录时间、用户名）
+
+---
+
+## 📝 六、操作审计与日志
+
+### 6.1 用户操作日志
+
+```prisma
+model UserOperationLog {
+  id          String   @id @default(uuid())
+  userId      String   // 操作用户ID
+  user        User     @relation(fields: [userId], references: [id])
+  
+  action      String   // 操作类型：LOGIN/LOGOUT/CREATE_USER/UPDATE_USER/DELETE_USER/...
+  targetType  String?  // 目标类型：USER/MATERIAL/DEPARTMENT/...
+  targetId    String?  // 目标ID
+  
+  details     Json?    // 操作详情（JSON格式，记录变更前后数据）
+  ipAddress   String?  // IP地址
+  userAgent   String?  // 用户代理
+  
+  createdAt   DateTime @default(now())
+  
+  @@index([userId])
+  @@index([action])
+  @@index([targetType, targetId])
+  @@index([createdAt])
+  @@map("user_operation_logs")
+}
+```
+
+**关键操作记录：**
+- 用户登录/登出
+- 用户创建/更新/删除
+- 部门创建/更新/删除
+- 权限配置变更
+- 素材上传/删除
+- 敏感操作（如：删除用户、修改权限）
+
+---
+
+## 🚀 七、实施建议
+
+### 7.1 分阶段实施
+
+**第一阶段：基础优化（1-2周）**
+1. 优化用户表结构（添加 `departmentId` 外键）
+2. 完善用户状态管理（`status` 字段）
+3. 增强用户搜索功能（多字段搜索）
+4. 添加用户操作日志
+
+**第二阶段：组织架构升级（2-3周）**
+1. 部门表支持层级结构（`parentId`）
+2. 部门编码系统
+3. 权限继承机制
+4. 部门管理员功能
+
+**第三阶段：权限体系完善（2-3周）**
+1. 角色枚举优化
+2. 权限矩阵实现
+3. 权限审计功能
+4. 批量权限管理
+
+### 7.2 数据迁移策略
+
+**用户数据迁移：**
+```sql
+-- 1. 将字符串 department 转换为 departmentId
+-- 2. 创建部门记录（如果不存在）
+-- 3. 更新用户表的 departmentId
+-- 4. 删除旧的 department 字段（可选）
+```
+
+**权限数据迁移：**
+```sql
+-- 1. 将字符串 department 转换为 departmentId
+-- 2. 更新权限表的 departmentId
+-- 3. 建立外键关联
+```
+
+### 7.3 兼容性考虑
+
+- **向后兼容**：保留 `department` 字符串字段一段时间，逐步迁移
+- **API兼容**：新旧API并存，逐步切换
+- **数据校验**：迁移过程中校验数据完整性
+
+---
+
+## 🎯 八、最佳实践建议
+
+### 8.1 组织架构管理
+
+1. **部门命名规范**
+   - 使用统一的命名格式（如：`设计部-3D组`）
+   - 避免重名，使用编码区分
+
+2. **部门层级控制**
+   - 建议最多3级，避免过度复杂
+   - 定期审查部门结构，合并冗余部门
+
+3. **部门负责人管理**
+   - 每个部门设置1个负责人
+   - 负责人自动获得部门管理员权限
+
+### 8.2 用户管理
+
+1. **新用户激活流程**
+   - 钉钉登录后自动创建账号（待激活状态）
+   - 管理员审核后激活，设置部门和角色
+   - 系统自动创建部门默认权限
+
+2. **用户离职处理**
+   - 使用软删除（`archived` 状态）
+   - 保留用户数据和操作日志（审计需要）
+   - 转移用户素材到其他用户（可选）
+
+3. **权限管理原则**
+   - **最小权限原则**：默认最小权限，按需授予
+   - **定期审查**：定期审查用户权限，及时回收
+   - **权限审计**：记录所有权限变更操作
+
+### 8.3 安全性
+
+1. **账号安全**
+   - 强制密码复杂度要求
+   - 支持双因素认证（2FA，未来扩展）
+   - 登录失败锁定机制
+
+2. **权限安全**
+   - 所有权限变更记录日志
+   - 敏感操作需要二次确认
+   - 定期权限审计报告
+
+3. **数据安全**
+   - 用户数据加密存储（敏感字段）
+   - 操作日志不可删除（只读）
+   - 定期数据备份
+
+---
+
+## 📈 九、未来扩展方向
+
+1. **组织架构同步**
+   - 与钉钉组织架构同步
+   - 自动创建/更新部门
+   - 自动同步用户信息
+
+2. **权限模板**
+   - 预设权限模板（如：设计师模板、市场人员模板）
+   - 批量应用权限模板
+
+3. **审批流程**
+   - 权限申请审批流程
+   - 部门创建审批流程
+   - 用户激活审批流程
+
+4. **数据分析**
+   - 用户活跃度分析
+   - 权限使用情况统计
+   - 部门素材贡献分析
+
+---
+
+## ✅ 总结
+
+这个设计方案的核心优势：
+
+1. **清晰的层级结构**：支持多级部门，灵活扩展
+2. **完善的权限体系**：RBAC模型，权限继承和覆盖
+3. **完整的生命周期**：从注册到离职的全流程管理
+4. **强大的审计能力**：操作日志、权限审计
+5. **良好的扩展性**：支持未来功能扩展
+
+**建议优先实施：**
+- 用户状态管理优化
+- 用户搜索功能增强
+- 部门外键关联
+- 操作日志系统
+
+这些改进可以立即提升系统的可用性和可维护性。

+# FRPC 配置检查报告
+
+**检查时间**: 2025-12-29  
+**服务器**: 192.168.58.20 (正式环境)
+
+---
+
+## ✅ 配置正确性检查
+
+### 1. 基本配置 ✅
+
+```toml
+serverAddr = "180.97.221.140"  ✅ 正确
+serverPort = 7000              ✅ 正确
+auth.method = "token"          ✅ 正确
+auth.token = "LiuYunKu_NAS_2024_SecureToken"  ✅ 正确
+```
+
+### 2. 与 FRPS 服务器匹配 ✅
+
+| 配置项 | FRPC | FRPS | 状态 |
+|--------|------|------|------|
+| 服务器地址 | 180.97.221.140 | 180.97.221.140 | ✅ 匹配 |
+| 控制端口 | 7000 | 7000 | ✅ 匹配 |
+| Token | LiuYunKu_NAS_2024_SecureToken | LiuYunKu_NAS_2024_SecureToken | ✅ 匹配 |
+| 认证方式 | token | token | ✅ 匹配 |
+
+### 3. youyidian-3d 代理配置 ✅
+
+```toml
+[[proxies]]
+name = "youyidian-3d"
+type = "tcp"                    ✅ 正确
+localIP = "127.0.0.1"           ✅ 正确（本地应用）
+localPort = 4320                ✅ 正确（应用端口）
+remotePort = 2320               ✅ 正确（frps允许的端口）
+transport.useCompression = true ✅ 正确
+```
+
+### 4. 端口权限 ✅
+
+- **remotePort = 2320** 在 frps 的 `allow_ports` 范围内（2320-2400）✅
+- **localPort = 4320** 应用正在监听 ✅
+
+---
+
+## ⚠️ 发现的问题
+
+### 🔴 问题 1: 重复的 FRPC 进程
+
+**发现**：有两个 frpc 进程同时运行！
+
+```
+PID 4747: /root/gongxiangp2/frp_0.52.3_linux_amd64/frpc -c /etc/frp/frpc.toml
+PID 9990: /usr/bin/frpc -c /etc/frp/frpc.toml
+```
+
+**影响**：
+- 两个进程都尝试连接到同一个 frps 服务器
+- 都使用相同的配置文件和相同的代理名称
+- 可能导致资源竞争和连接冲突
+- **这很可能是导致工作连接失败的根本原因！**
+
+**建议**：
+- 只保留一个 frpc 进程
+- 检查是否有 systemd 服务管理 frpc
+- 如果两个都是手动启动的，需要停止其中一个
+
+### ⚠️ 问题 2: 其他代理的错误（不影响 youyidian-3d）
+
+日志中显示 `nas_netbios` 和 `nas_smb` 有 "port not allowed" 错误，但这些不影响 youyidian-3d 的功能。
+
+---
+
+## 📊 配置验证结果
+
+| 检查项 | 状态 | 说明 |
+|--------|------|------|
+| 配置文件语法 | ✅ 正确 | TOML 格式正确 |
+| 服务器地址 | ✅ 正确 | 指向正确的 frps |
+| 端口配置 | ✅ 正确 | 控制端口和应用端口都正确 |
+| Token 认证 | ✅ 正确 | 与 frps 匹配 |
+| 代理配置 | ✅ 正确 | youyidian-3d 配置完整 |
+| 端口权限 | ✅ 正确 | 2320 在允许范围内 |
+| **进程数量** | ❌ **异常** | **两个进程同时运行** |
+
+---
+
+## 🎯 结论
+
+### 配置本身是正确的 ✅
+
+frpc 的配置文件 `/etc/frp/frpc.toml` **配置完全正确**：
+- ✅ 所有参数都正确
+- ✅ 与 frps 服务器配置匹配
+- ✅ youyidian-3d 代理配置正确
+- ✅ 端口权限正确
+
+### 但存在进程冲突问题 ❌
+
+**两个 frpc 进程同时运行**，这可能导致：
+1. 资源竞争
+2. 连接冲突
+3. 工作连接建立失败（这正好解释了 502 错误）
+
+---
+
+## 🛠️ 建议的修复步骤
+
+### 步骤 1: 检查是否有 systemd 服务
+
+```bash
+systemctl status frpc
+systemctl list-units | grep frpc
+```
+
+### 步骤 2: 确定保留哪个进程
+
+建议保留：
+- **PID 4747** (`/root/gongxiangp2/frp_0.52.3_linux_amd64/frpc`) - 如果这是您手动启动的
+- 或者
+- **PID 9990** (`/usr/bin/frpc`) - 如果这是通过 systemd 管理的
+
+### 步骤 3: 停止多余的进程
+
+```bash
+# 如果保留 PID 4747，停止 PID 9990
+kill 9990
+
+# 如果保留 PID 9990，停止 PID 4747
+kill 4747
+
+# 或者如果 PID 9990 是 systemd 管理的
+systemctl stop frpc
+```
+
+### 步骤 4: 验证修复
+
+```bash
+# 检查进程
+ps aux | grep frpc
+
+# 检查连接
+netstat -an | grep 180.97.221.140:7000
+
+# 等待几秒后，检查 frps 日志
+ssh root@180.97.221.140 "tail -20 /var/log/frps.log | grep youyidian"
+```
+
+---
+
+## 📝 总结
+
+**配置是正确的，但需要解决进程冲突问题。**
+
+修复进程冲突后，502 错误应该会消失。

+
+## 🔍 两个 FRPC 进程的用途分析
+
+### 进程 1: PID 4747 (Systemd 管理) ✅
+
+**用途**: 代理 3D素材系统和其他NAS服务
+
+**详细信息**:
+- **进程**: `/root/gongxiangp2/frp_0.52.3_linux_amd64/frpc -c /etc/frp/frpc.toml`
+- **管理方式**: Systemd 服务 (`frpc.service`)
+- **配置文件**: `/etc/frp/frpc.toml`
+- **FRPS 服务器**: `180.97.221.140:7000`
+- **Token**: `LiuYunKu_NAS_2024_SecureToken`
+- **日志文件**: `/root/frp/frpc.log`
+
+**代理的服务**:
+1. **youyidian-3d** (TCP)
+   - 本地: `127.0.0.1:4320`
+   - 远程: `2320`
+   - **这是导致502错误的服务！**
+
+2. **nas_smb** (TCP)
+   - 本地: `192.168.58.20:445`
+   - 远程: `445`
+   - 状态: ❌ port not allowed (frps配置问题)
+
+3. **nas_netbios** (TCP)
+   - 本地: `192.168.58.20:139`
+   - 远程: `139`
+   - 状态: ❌ port not allowed (frps配置问题)
+
+**连接状态**: ✅ 已建立连接
+```
+192.168.58.20:48772 → 180.97.221.140:7000 ESTABLISHED
+```
+
+---
+
+### 进程 2: PID 9990 ⚠️ **配置错误**
+
+**预期用途**: 代理 MinIO 服务
+
+**详细信息**:
+- **进程**: `/usr/bin/frpc -c /etc/frp/frpc.toml`
+- **管理方式**: 未知（可能是手动启动或另一个服务）
+- **配置文件**: `/etc/frp/frpc.toml` ❌ **错误！应该使用 `/mnt/tank/apps/frp-minio/frpc.toml`**
+- **FRPS 服务器**: 应该连接到 `103.118.245.6:7001`，但实际使用了错误的配置
+- **Token**: 应该使用 `MinIO_FRP_2025_SecureToken_For_Storage`，但实际使用了错误的token
+
+**应该代理的服务** (根据 `/mnt/tank/apps/frp-minio/frpc.toml`):
+1. **minio-api** (HTTP)
+   - 本地: `172.17.0.1:9000`
+   - 域名: `s3.yydd.ai`
+   - **用于 MinIO API 访问**
+
+2. **minio-console** (TCP)
+   - 本地: `172.17.0.1:9001`
+   - 远程: `2901`
+   - **用于 MinIO 控制台访问**
+
+**连接状态**: ❌ **没有建立连接**
+- 应该连接到 `103.118.245.6:7001`，但没有连接
+- 因为使用了错误的配置文件，尝试连接到 `180.97.221.140:7000`（与进程1冲突）
+
+---
+
+## 🔴 问题分析
+
+### 问题 1: PID 9990 使用了错误的配置文件
+
+**当前状态**:
+- PID 9990 使用: `/etc/frp/frpc.toml` (3D素材系统的配置)
+- 应该使用: `/mnt/tank/apps/frp-minio/frpc.toml` (MinIO的配置)
+
+**影响**:
+1. ❌ PID 9990 尝试连接到错误的 frps 服务器 (`180.97.221.140:7000`)
+2. ❌ 与 PID 4747 使用相同的配置，导致资源竞争
+3. ❌ MinIO 服务无法通过 frp 访问
+4. ❌ 可能影响 youyidian-3d 的工作连接建立
+
+### 问题 2: 两个进程的冲突
+
+虽然两个进程有不同的用途，但它们都使用了 `/etc/frp/frpc.toml`，导致：
+- 都尝试连接到同一个 frps 服务器
+- 都尝试使用相同的代理名称（如果有冲突）
+- 资源竞争可能导致工作连接失败
+
+---
+
+## ✅ 正确的配置应该是
+
+### 进程 1 (PID 4747) - 3D素材系统
+- ✅ 配置文件: `/etc/frp/frpc.toml`
+- ✅ FRPS: `180.97.221.140:7000`
+- ✅ 代理: youyidian-3d (4320 → 2320)
+
+### 进程 2 (PID 9990) - MinIO
+- ❌ **当前**: `/etc/frp/frpc.toml` (错误)
+- ✅ **应该**: `/mnt/tank/apps/frp-minio/frpc.toml`
+- ❌ **当前**: FRPS `180.97.221.140:7000` (错误)
+- ✅ **应该**: FRPS `103.118.245.6:7001`
+- ✅ 代理: minio-api (9000 → s3.yydd.ai), minio-console (9001 → 2901)
+
+---
+
+## 🛠️ 解决方案
+
+### 方案 1: 修复 PID 9990 的配置（推荐）
+
+**步骤**:
+
+1. **停止当前的 PID 9990 进程**:
+```bash
+kill 9990
+```
+
+2. **使用正确的配置文件启动 MinIO FRPC**:
+```bash
+# 方法1: 使用启动脚本（推荐）
+cd /mnt/tank/apps/frp-minio
+./start-frpc.sh
+
+# 方法2: 手动启动（如果脚本不可用）
+/usr/bin/frpc -c /mnt/tank/apps/frp-minio/frpc.toml
+```
+
+3. **或者使用 Docker 容器**（根据启动脚本）:
+```bash
+docker run -d --name frpc-minio --restart=always \
+  -v /mnt/tank/apps/frp-minio/frpc.toml:/etc/frp/frpc.toml \
+  snowdreamtech/frpc:latest
+```
+
+### 方案 2: 检查是否有 systemd 服务管理 MinIO FRPC
+
+```bash
+systemctl list-units | grep -i minio
+systemctl list-units | grep -i frpc
+```
+
+如果有服务，检查并修复服务配置。
+

+
+## 📊 当前状态总结
+
+| 进程 | 用途 | 配置文件 | FRPS服务器 | 连接状态 | 状态 |
+|------|------|----------|------------|----------|------|
+| PID 4747 | 3D素材系统 | `/etc/frp/frpc.toml` ✅ | `180.97.221.140:7000` ✅ | ✅ 已连接 | ✅ 正常 |
+| PID 9990 | MinIO | `/etc/frp/frpc.toml` ❌ | `180.97.221.140:7000` ❌ | ❌ 未连接 | ❌ **配置错误** |
+
+---
+
+## ✅ 重要发现
+
+### PID 9990 实际上是 Docker 容器内的进程！
+
+**详细信息**:
+- **容器名称**: `frpc-minio`
+- **容器PID**: 9990 (在宿主机上的PID)
+- **配置文件**: 容器内 `/etc/frp/frpc.toml` = 宿主机 `/mnt/tank/apps/frp-minio/frpc.toml` ✅
+- **配置内容**: ✅ 正确（MinIO配置，连接到 `103.118.245.6:7001`）
+
+**结论**: PID 9990 的配置实际上是**正确的**！它使用的是 MinIO 的配置文件，连接到不同的 frps 服务器。
+
+---
+
+## 🎯 最终结论
+
+1. ✅ **PID 4747 配置正确**，用于 3D素材系统，连接到 `180.97.221.140:7000`
+2. ✅ **PID 9990 (Docker容器) 配置正确**，用于 MinIO，连接到 `103.118.245.6:7001`
+3. ✅ **两个进程使用不同的配置文件和不同的 frps 服务器，不会冲突**
+
+### 那么问题在哪里？
+
+既然两个进程配置都正确，且连接到不同的服务器，那么 502 错误的原因可能是：
+
+1. **PID 4747 的工作连接问题**（之前分析的 frps 日志中的超时）
+2. **网络问题**导致工作连接无法建立
+3. **frps 服务器端的配置或资源问题**
+
+**建议**: 继续排查 PID 4747 的工作连接问题，两个进程本身没有冲突。

+# 批量上传流程完整检查报告
+
+**检查时间**: 2025-12-29  
+**检查范围**: 批量上传功能的完整流程链路
+
+---
+
+## 📋 检查清单
+
+- [x] 批量上传功能触发
+- [x] 批量上传的追加/减少素材数量逻辑
+- [x] 源文件存放
+- [x] 预览图压缩处理
+- [x] 预览图存放
+- [x] 素材卡片的正确展示
+- [x] 预览图展示
+- [x] 源文件下载
+
+---
+
+## 1. 批量上传功能触发 ✅
+
+### 1.1 触发方式
+
+**位置**: `components/UploadModal.tsx`
+
+**触发条件**:
+1. **通用批量上传**: 选择多个文件（>1个）时自动进入批量模式
+   - 文件选择处理: `handleFileSelection` (`components/upload/file-input-handlers.ts`)
+   - 自动创建批量项: `createBatchFileItems` (`components/upload/file-handlers.ts`)
+   - 设置批量模式: `setIsBatchMode(true)`
+
+2. **特殊类型批量上传**: 特定素材类型有专门的批量上传入口
+   - 音乐: `batchMusicFiles` (最多100个)
+   - 种草视频: `batchVideoFiles` (最多8个)
+   - 3D场景: `batch3DFiles` (最多5个，每个需要预览图)
+   - 品牌VI: `batchBrandVIFiles` (最多50个PDF)
+   - 买家秀: `batchBuyerShowFiles` (每批至少8张图)
+   - 小红书: `batchXiaohongshuFiles` (支持批量)
+
+### 1.2 文件验证
+
+**位置**: `components/upload/file-handlers.ts` → `validateAndFilterFiles`
+
+**验证逻辑**:
+- ✅ 使用 `isValidMainFileType` 验证文件类型
+- ✅ 过滤无效文件，只保留有效文件
+- ✅ 返回 `{ valid, invalid }` 结果
+
+### 1.3 状态管理
+
+**位置**: `components/UploadModal.tsx`
+
+**状态变量**:
+```typescript
+const [batchFiles, setBatchFiles] = useState<BatchFileItem[]>([])
+const [isBatchMode, setIsBatchMode] = useState(false)
+```
+
+**结论**: ✅ **触发逻辑正常**
+
+---
+
+## 2. 批量上传的追加/减少素材数量逻辑 ✅
+
+### 2.1 追加文件
+
+**位置**: `components/upload/file-input-handlers.ts` → `handleFileSelection`
+
+**追加逻辑**:
+```typescript
+// 通用批量上传
+const newItems = createBatchFileItems(files, ...)
+setBatchFiles(prev => [...prev, ...newItems])
+
+// 特殊类型批量上传
+setBatchMusicFiles(prev => [...prev, ...newFiles])
+setBatchVideoFiles(prev => [...prev, ...newFiles])
+// ... 其他类型类似
+```
+
+**限制检查**:
+- ✅ 检查批量限制 (`BATCH_LIMITS`)
+- ✅ 音乐: 最多100个
+- ✅ 种草视频: 最多8个
+- ✅ 3D场景: 最多5个
+- ✅ 品牌VI: 最多50个
+
+### 2.2 删除文件
+
+**位置**: `components/upload/BatchFileList.tsx` → `onDelete`
+
+**删除逻辑**:
+```typescript
+onDelete={(index) => {
+  setBatchFiles(batchFiles.filter((_, i) => i !== index))
+  if (batchFiles.length === 1) {
+    setIsBatchMode(false) // 只剩一个时退出批量模式
+  }
+}}
+```
+
+**特殊处理**:
+- ✅ 删除时自动释放预览图URL (`URL.revokeObjectURL`)
+- ✅ 删除最后一个文件时自动退出批量模式
+
+### 2.3 更新文件信息
+
+**位置**: `components/upload/BatchFileList.tsx`
+
+**支持的操作**:
+- ✅ 更新SPU型号: `onUpdateProductModel`
+- ✅ 更新预览图: `onUpdatePreviewImage` / `onRemovePreviewImage`
+- ✅ 更新分类信息: `onUpdateCategory`, `onUpdateScene`, `onUpdatePlatform`, `onUpdateProductCategory`
+- ✅ 更新渲染器: `onUpdateRenderer` (3D场景)
+
+**结论**: ✅ **追加/减少逻辑正常**
+
+---
+
+## 3. 源文件存放 ✅
+
+### 3.1 上传路径
+
+**位置**: `app/api/materials/upload/route.ts`
+
+**存放逻辑**:
+```typescript
+// 主文件一律本地化存储到 uploads 目录
+const uploadDir = process.env.UPLOAD_DIR || './uploads'
+await fs.mkdir(uploadDir, { recursive: true })
+
+// 根据类型决定文件名前缀
+const basePrefix = isVideoOrAudio
+  ? materialType === '音乐'
+    ? 'audio-source'  // 音频: audio-source-*.mp3
+    : 'video'         // 视频: video-*.mp4
+  : 'material'       // 其他: material-*.zip
+
+zipFileName = generateUniqueFilename(basePrefix, ext)
+zipFilePath = path.join(uploadDir, zipFileName)
+```
+
+### 3.2 分片上传处理
+
+**位置**: `app/api/materials/upload/complete/route.ts`
+
+**处理流程**:
+1. ✅ 接收分片并合并
+2. ✅ 合并后文件移动到最终位置: `fs.rename(sourcePath, zipFilePath)`
+3. ✅ 避免重复读写大文件
+
+### 3.3 文件命名规则
+
+**位置**: `app/api/materials/upload/route.ts` → `generateUniqueFilename`
+
+**命名格式**:
+- 视频: `video-{timestamp}-{hash}.mp4`
+- 音频: `audio-source-{materialId}-{timestamp}.mp3`
+- 其他: `material-{timestamp}-{hash}.zip`
+
+**结论**: ✅ **源文件存放逻辑正常**
+
+---
+
+## 4. 预览图压缩处理 ✅
+
+### 4.1 压缩函数
+
+**位置**: `components/upload/image-processor.ts` → `compressPreviewImage`
+
+**压缩逻辑**:
+```typescript
+export async function compressPreviewImage(file: File): Promise<File> {
+  const img = await loadImage(file)
+  const maxWidth = 800
+  const maxHeight = 2000
+  const ratio = Math.min(maxWidth / width, maxHeight / height, 1)
+  // 使用 Canvas 压缩，质量 0.85
+  return await canvasToFile(canvas, file, 0.85)
+}
+```
+
+**压缩参数**:
+- ✅ 最大宽度: 800px
+- ✅ 最大高度: 2000px
+- ✅ 质量: 0.85
+- ✅ 格式: JPEG
+
+### 4.2 批量上传中的压缩
+
+**位置**: `components/upload/batch-upload-handlers.ts` → `uploadBatchFile`
+
+**处理流程**:
+```typescript
+// 处理预览图（如果需要）- 先压缩再转换为base64
+const needsPreview = !PREVIEW_OPTIONAL_TYPES.includes(materialType) && materialType !== '详情页'
+if (needsPreview && item.previewImage) {
+  compressedPreview = await compressPreviewImage(item.previewImage)
+  metadata.previewImage = await fileToBase64String(compressedPreview)
+}
+```
+
+**处理时机**:
+- ✅ 大文件（分片上传）: 压缩后转为base64，在 `completeBatchUpload` 时使用
+- ✅ 小文件（直接上传）: 压缩后直接添加到 FormData
+
+### 4.3 展示图切片
+
+**位置**: `components/upload/image-processor.ts` → `compressAndSliceDisplayImage`
+
+**切片逻辑**:
+- ✅ 高度 > 1500px 时自动切片
+- ✅ 每片高度: 1500px
+- ✅ 用于详情页展示（长图自动切片）
+
+**结论**: ✅ **预览图压缩处理逻辑正常**
+
+---
+
+## 5. 预览图存放 ✅
+
+### 5.1 上传到S3
+
+**位置**: `app/api/materials/upload/route.ts`
+
+**上传逻辑**:
+```typescript
+// 处理预览图（第一张作为主预览图）
+if (previewImage && !['详情页', '模特'].includes(materialType)) {
+  const buffer = Buffer.from(await previewImage.arrayBuffer())
+  const filename = generateUniqueFilename('preview', path.extname(previewImage.name))
+  previewUrl = await uploadToS3(buffer, filename, previewImage.type)
+}
+
+// 处理其他预览图（作为展示图）- 并行处理
+if (previewImages.length > 0) {
+  const uploadPromises = previewImages.map(async (image, index) => {
+    const buffer = Buffer.from(await image.arrayBuffer())
+    const filename = generateUniqueFilename(`preview-${index + 2}`, path.extname(image.name))
+    const url = await uploadToS3(buffer, filename, image.type)
+    return url
+  })
+  const urls = await Promise.all(uploadPromises)
+  displayImages.push(...urls)
+}
+```
+
+### 5.2 S3配置
+
+**位置**: `lib/s3.ts`
+
+**配置信息**:
+- ✅ Endpoint: `s3.yydd.ai` (新素材)
+- ✅ Bucket: `gongxiangpan`
+- ✅ 路径前缀: `由壹点AI/`
+- ✅ URL格式: `https://s3.yydd.ai/gongxiangpan/由壹点AI/preview-{timestamp}-{hash}.jpg`
+
+### 5.3 数据库存储
+
+**位置**: `app/api/materials/upload/route.ts`
+
+**存储字段**:
+- ✅ `previewUrl`: 主预览图URL（第一张）
+- ✅ `displayImages`: 展示图URLs数组（其他预览图）
+
+**结论**: ✅ **预览图存放逻辑正常**
+
+---
+
+## 6. 素材卡片的正确展示 ✅
+
+### 6.1 素材列表API
+
+**位置**: `app/api/materials/route.ts`
+
+**返回数据**:
+- ✅ 包含 `previewUrl` (主预览图)
+- ✅ 包含 `displayImages` (展示图数组)
+- ✅ 包含所有素材信息（SPU、分类、类型等）
+- ✅ URL重写: `rewriteMaterialStorageUrlsForClient` (`lib/url-rewrite.ts`)
+
+### 6.2 素材卡片组件
+
+**位置**: `components/home/MaterialCard.tsx`
+
+**展示逻辑**:
+```typescript
+// 视频类型
+{isVideoType && videoPreviewUrl ? (
+  <video src={videoPreviewUrl} poster={posterUrl} ... />
+) : material.previewUrl ? (
+  <Image src={material.previewUrl} ... />
+) : (
+  <div>暂无预览图</div>
+)}
+```
+
+**展示内容**:
+- ✅ SPU标签（左上角）
+- ✅ 素材类型角标（右上角）
+- ✅ 视频时长角标（视频类型）
+- ✅ 转码进度显示（转码中）
+
+### 6.3 素材网格布局
+
+**位置**: `components/home/MaterialGrid.tsx`
+
+**布局逻辑**:
+- ✅ 响应式网格布局
+- ✅ 支持无限滚动加载
+- ✅ 卡片悬停效果
+
+**结论**: ✅ **素材卡片展示逻辑正常**
+
+---
+
+## 7. 预览图展示 ✅
+
+### 7.1 列表页预览
+
+**位置**: `components/home/MaterialCard.tsx`
+
+**预览逻辑**:
+- ✅ 视频类型: 显示视频预览（`videoPreviewClipUrl` 或 `videoPreview540Url`）
+- ✅ 图片类型: 显示 `previewUrl`
+- ✅ 音频类型: 显示占位符或音频封面
+- ✅ 无预览图: 显示"暂无预览图"占位符
+
+### 7.2 详情页预览
+
+**位置**: `app/share/[id]/page.tsx`
+
+**预览逻辑**:
+- ✅ 主预览图: `material.previewUrl`
+- ✅ 展示图: `material.displayImages` 数组
+- ✅ 支持图片放大查看
+- ✅ 长图自动切片展示
+
+### 7.3 URL重写
+
+**位置**: `lib/url-rewrite.ts`
+
+**重写逻辑**:
+- ✅ 将内网URL (`http://localhost:9000/...`) 替换为公网地址
+- ✅ 优先使用 `S3_PUBLIC_DOMAIN`
+- ✅ 相对路径保持不变
+
+**结论**: ✅ **预览图展示逻辑正常**
+
+---
+
+## 8. 源文件下载 ✅
+
+### 8.1 下载API
+
+**位置**: `app/api/materials/download/route.ts`
+
+**下载逻辑**:
+```typescript
+// 1. 权限检查
+- 登录检查

+- 部门权限检查
+
+// 2. 文件路径处理
+const isOldMaterial = material.zipFilePath.includes('103.118.245.6') || material.zipFilePath.startsWith('http')
+if (!isOldMaterial) {
+  // 新素材: 相对路径转绝对路径
+  filePath = path.join(process.cwd(), filePath)
+}
+
+// 3. 文件读取和流式返回
+const fileStream = createReadStream(filePath)
+// 支持 Range 请求（断点续传）
+```
+
+### 8.2 下载路径兼容
+
+**兼容逻辑**:
+- ✅ 新素材: `uploads/video-*.mp4` 或 `uploads/material-*.zip`
+- ✅ 老素材: HTTP URL 或外网服务器路径
+- ✅ 动态打包: 无源文件时，从 `displayImages` 动态打包ZIP
+
+### 8.3 下载文件名

+
+## 🔧 实现方案
+
+### 1. 修改详情页布局 (`app/share/[id]/page.tsx`)
+
+**变更点：**
+- 移除左侧下方的SKU列表（line 519-528）
+- 在右侧卡片内添加SKU列表（标准模型类型时）
+- 条件渲染右侧卡片内容：标准模型类型时只显示标题、标签、SKU列表和操作按钮
+
+**代码结构：**
+```tsx
+{/* 右侧：素材信息（固定） */}
+<div className="w-80 flex-shrink-0">
+  <div className="sticky top-24 bg-white dark:bg-gray-800 rounded-2xl shadow-lg p-8 space-y-6">
+    {/* 标题和标签 */}
+    <div>
+      <h1>{material.productModel}</h1>
+      <div className="flex flex-wrap gap-2">
+        {/* 标签 */}
+      </div>
+    </div>
+
+    {/* 标准模型：显示SKU列表 */}
+    {material.materialType === '标准模型' ? (
+      <SkuList
+        materialId={materialId}
+        canEdit={canEdit}
+        onEditClick={() => setShowSkuEditModal(true)}
+      />
+    ) : (
+      /* 其他类型：显示素材信息 */
+      <div className="space-y-4">
+        {/* 作者、文件大小、下载次数等 */}
+      </div>
+    )}
+
+    {/* 操作按钮 */}
+    <div className="space-y-3 pt-2">
+      {/* 下载按钮、返回按钮 */}
+    </div>
+  </div>
+</div>
+```
+
+### 2. 优化SkuList组件 (`components/SkuList.tsx`)
+
+**变更点：**
+- 调整样式以适应右侧卡片布局
+- 优化列表项显示（更紧凑）
+- 保持全选/多选/单选的下载功能
+
+**样式调整：**
+- 移除固定高度限制，使用flex布局自适应
+- 优化间距和字体大小
+- 确保在320px宽度内正常显示
+
+### 3. 改进SkuEditModal组件 (`components/SkuEditModal.tsx`)
+
+**核心改进：文件选择后立即显示，显示上传进度**
+
+**实现思路：**
+1. 添加"待上传SKU"状态管理
+2. 文件选择后立即添加到待上传列表
+3. 显示上传进度（类似BatchFileList）
+4. 上传完成后从待上传列表移除，添加到正式列表
+
+**状态结构：**
+```typescript
+interface PendingSku {
+  id: string // 临时ID
+  skuName: string
+  previewFile: File | null
+  previewUrl: string | null // 上传后的URL
+  zipFile: File | null
+  zipFileInfo: { fileName: string; filePath: string; fileSize: number } | null
+  previewUploadProgress: number // 0-100
+  zipUploadProgress: number // 0-100
+  status: 'pending' | 'uploading-preview' | 'uploading-zip' | 'saving' | 'done' | 'error'
+  error?: string
+}
+```
+
+**UI流程：**
+```
+用户点击"添加SKU"
+    ↓
+显示添加表单
+    ↓
+用户填写SKU名称
+    ↓
+用户选择预览图 → 立即显示在列表中，状态：上传中预览图
+    ↓
+预览图上传完成 → 更新状态：预览图完成
+    ↓
+用户选择压缩包 → 立即显示在列表中，状态：上传中压缩包
+    ↓
+压缩包上传完成 → 更新状态：压缩包完成
+    ↓
+用户点击"添加"按钮 → 状态：保存中
+    ↓
+保存完成 → 从待上传列表移除，添加到正式列表
+```
+
+**参考实现：**
+- 参考 `components/upload/BatchFileList.tsx` 的文件列表展示
+- 参考 `components/upload/UploadProgress.tsx` 的进度显示
+- 参考 `hooks/useBatchFilesUpload.ts` 的上传状态管理
+
+---

+# 标准模型素材类型逻辑梳理报告
+
+## 📋 概述
+
+标准模型是一种特殊的素材类型，用于以产品型号（SPU）为基准创建模型合集。上传时只需填写SPU和预览图，创建后可以在详情页添加各个SKU的模型文件。
+

+
+## 🗂️ 数据库结构
+
+### Material 表（标准模型相关字段）
+
+```prisma

+
+**⚠️ 发现的问题：**
+- MaterialSku表**缺少`previewUrl`字段**，但前端组件（SkuList、SkuEditModal）都在使用该字段
+- 前端上传预览图到S3后，在创建SKU时传递了`previewUrl`，但后端API未接收和存储
+

+| `productCategoryName` | ✅ 必填 | 品类分类 |
+| `previewImages` | ✅ 必填 | 预览图（至少1张） |
+| `categoryName` | ❌ 自动填充 | 自动填充为"通用" |
+| `sceneName` | ❌ 自动填充 | 自动填充为"通用" |
+| `zipFile` | ❌ 可选 | 主文件可选（与模特类型相同） |
+
+### SKU添加时必填字段
+
+| 字段 | 是否必填 | 说明 |
+|------|---------|------|
+| `skuName` | ✅ 必填 | SKU名称 |

+## 🎨 前端组件
+
+### 1. UploadModal（上传弹窗）
+
+**文件位置：** `components/UploadModal.tsx`
+
+**标准模型相关逻辑：**
+- 选择"标准模型"类型时，隐藏店铺和场景字段
+- 显示品类选择字段（必填）
+- 显示标准模型说明提示框
+- 验证：SPU、品类、预览图必填，主文件可选
+
+**关键代码：**
+```typescript
+// 验证品类（line 1292-1295）
+if (requiresProductCategoryName(materialType) && !productCategoryName) {
+  setError('标准模型类型必须选择品类')
+  return
+}
+
+// 验证主文件（line 1302-1306）
+if (materialType !== '模特' && materialType !== '标准模型' && !zipFile) {
+  setError('请上传素材文件')
+  return
+}
+
+// 验证预览图（line 1326-1329）
+if (materialType === '标准模型' && previewImages.length === 0) {
+  setError('标准模型必须上传预览图')
+  return
+}
+```
+
+### 2. UploadForm（上传表单字段）
+
+**文件位置：** `components/upload/UploadForm.tsx`
+
+**标准模型相关逻辑：**
+- 标准模型不显示店铺和场景字段（line 144-210, 212-278）
+- 标准模型显示品类字段（必填）（line 280-300）
+- 标准模型不显示平台字段（line 302-322）
+- 显示标准模型说明提示（line 343-356）
+
+### 3. SkuList（SKU列表组件）
+
+**文件位置：** `components/SkuList.tsx`
+
+**功能：**
+- 显示SKU列表（按sortOrder排序）
+- 支持全选/单选SKU
+- 支持单个/批量下载SKU
+- 支持预览图点击放大
+- 显示SKU名称、文件大小
+
+**⚠️ 问题：**
+- 使用`sku.previewUrl`字段（line 231），但数据库中没有该字段
+- API返回的SKU数据中没有`previewUrl`
+
+### 4. SkuEditModal（SKU编辑弹窗）
+
+**文件位置：** `components/SkuEditModal.tsx`
+
+**功能：**
+- 显示SKU列表
+- 添加新SKU（名称、预览图、压缩包）
+- 删除SKU
+- 调整SKU排序（上移/下移）
+- 支持拖拽上传预览图和压缩包
+
+**⚠️ 问题：**
+- 上传预览图到S3后，在创建SKU时传递了`previewUrl`（line 186）
+- 但后端API未接收和存储`previewUrl`字段
+
+---
+
+## ⚠️ 发现的问题
+
+### 1. MaterialSku表缺少previewUrl字段
+
+**问题描述：**
+- 前端组件（SkuList、SkuEditModal）都在使用`sku.previewUrl`字段
+- 但MaterialSku表结构中没有`previewUrl`字段
+- 前端上传预览图后，在创建SKU时传递了`previewUrl`，但后端未接收和存储
+
+**影响：**
+- SKU列表无法显示预览图
+- SKU编辑弹窗中无法显示已上传的预览图
+
+**解决方案：**
+1. 在MaterialSku表中添加`previewUrl`字段
+2. 修改后端API接收和存储`previewUrl`
+3. 更新Prisma schema并执行迁移
+
+### 2. SKU上传API的字段不一致
+
+**问题描述：**
+- `SkuEditModal`中上传压缩包后，调用`POST /api/materials/{id}/skus`时传递了：
+  - `skuName`
+  - `previewUrl`
+  - `zipFileName`
+  - `zipFilePath`
+  - `zipFileSize`
+- 但后端API只接收了：
+  - `skuName`
+  - `filePath`（对应前端的`zipFilePath`）
+  - `fileSize`（对应前端的`zipFileSize`）
+- 缺少`previewUrl`和`zipFileName`的接收
+
+**解决方案：**
+1. 修改后端API接收`previewUrl`和`zipFileName`
+2. 在MaterialSku表中添加`previewUrl`和`zipFileName`字段（如果需要）
+
+### 3. SKU文件路径存储方式不一致
+
+**问题描述：**
+- `POST /api/materials/{id}/skus/upload`保存文件到`uploads/skus/{materialId}/`，返回相对路径`skus/{materialId}/{fileName}`
+- `POST /api/materials/{id}/skus`接收`filePath`，直接存储到数据库
+- 但前端传递的是`zipFilePath`，需要确认字段名是否一致
+
+**解决方案：**
+- 统一字段命名：使用`filePath`存储相对路径，使用`zipFileName`存储文件名
+
+---
+
+## 📂 文件存储结构
+
+### 标准模型主文件（可选）
+```
+uploads/
+  {timestamp}-{random}.zip  # 如果上传了主文件
+```
+
+### SKU文件
+```
+uploads/
+  skus/
+    {materialId}/
+      {skuName}_{timestamp}.zip
+      {skuName}_{timestamp}.zip
+      ...
+```
+
+### 预览图（S3存储）
+- Material预览图：`s3://bucket/preview-{timestamp}-{random}.{ext}`
+- SKU预览图：`s3://bucket/preview-{timestamp}-{random}.{ext}`（如果添加了previewUrl字段）
+

+
+## 🔍 验证逻辑代码位置
+
+### 前端验证
+
+**文件：** `lib/material-validation.ts`
+
+```typescript
+// 标准模型不需要店铺和场景
+export function requiresCategoryAndScene(materialType: string): boolean {
+  return !AUTO_GENERAL_TYPES.includes(materialType) && materialType !== '标准模型';
+}
+
+// 标准模型需要品类
+export function requiresProductCategoryName(materialType: string): boolean {
+  return materialType === '标准模型';
+}
+
+// 标准模型自动填充"通用"
+export function shouldAutoFillGeneral(materialType: string): boolean {
+  return AUTO_GENERAL_TYPES.includes(materialType) || materialType === '标准模型';
+}
+```
+
+### 后端验证
+
+**文件：** `app/api/materials/upload/route.ts`
+
+```typescript
+// 验证主文件（line 94-102）
+const requiresMainFile = !['模特', '标准模型', '买家秀图片', '小红书种草'].includes(materialType);
+const hasMainFile = !!zipFile || !!existingFilePath;
+if (requiresMainFile && !hasMainFile) {
+  return NextResponse.json({ error: '请上传素材文件' }, { status: 400 });
+}
+```
