+
+## 项目概述
+
+没事Music 是一个基于 Web 的音乐播放器应用,采用单文件 React 架构,支持多平台音乐搜索、播放和同步功能。
+
+## 架构设计
+
+### 前端架构 (index.html)
+
+**单文件应用模式**:
+- 所有前端代码集中在 `index.html` (~89KB)
+- 使用 Babel Standalone 在浏览器端编译 JSX
+- React 18 + Tailwind CSS + Font Awesome (均通过 CDN 引入)
+
+**核心组件结构**:
+```
+App (主容器)
+├── SideDrawer (侧边栏设置)
+├── MiniPlayer (迷你播放器)
+├── FullPlayer (全屏播放器)
+├── PlaylistDrawer (播放列表)
+└── TopListPage (排行榜页面)
+```
+
+**状态管理**:
+- 使用 React Hooks (useState, useEffect, useRef, useMemo, useCallback)
+- 数据持久化: localStorage (前缀 `th_`)
+- 关键状态: playlist, favorites, currentSong, syncToken, syncMode
+
+**数据规范化**:
+- `normalizeSongId()`: 全局强制歌曲 ID 为字符串类型
+- `normalizeSongList()`: 批量规范化歌曲列表
+- `getSongDurationSeconds()`: 统一处理不同来源的时长字段 (duration/dt/time/interval/length/playTime)
+
+### 后端架构 (sync-server/server.js)
+
+**KV 存储服务**:
+- 基于 Node.js 原生 HTTP 服务器
+- 文件系统存储: `data/{token}_{key}.json`
+- API 端点: `GET/POST /kv/:key?token=...`
+- Token 用于用户隔离
+
+**后台下载管理器**:
+- 自动检测歌曲列表数据并触发下载
+- 文件命名: `{歌手} - {歌名} [{平台}_{ID}]`
+- 文件名清理: Unicode 规范化 (NFC) + 非法字符替换
+- 存储路径: `MUSIC_DIR` (默认 `./music`)
+
+### 同步策略
+
+**两种同步模式**:
+1. **私有云同步** (`syncMode: 'server'`):
+   - 基于 Token 的 KV 存储
+   - 增量同步: 计算本地与上次同步的差异 (added/removed)
+   - 自动同步: 每 15 分钟执行一次
+
+2. **网易云歌单同步** (`syncMode: 'netease_playlist'`):
+   - 通过 TuneHub API 获取歌单
+   - 导入即替换逻辑
+   - 自动同步: 每 15 分钟执行一次
+
+**同步流程**:
+```
+拉取远程 → 计算差异 → 合并本地(非覆盖) → 推送至私有云
+```
+
+### 外部 API 集成
+
+**TuneHub API** (https://music-dl.sayqz.com):
+- 搜索: `/api/?type=search&keyword=...&source=...`
+- 歌词: `/api/?source=...&id=...&type=lrc`
+- 排行榜列表: `/api/?source=...&type=toplists`
+- 排行榜歌曲: `/api/?source=...&id=...&type=toplist`
+- 歌单详情: `/api/?type=playlist&id=...&source=...`
+
+**支持平台**: netease, kuwo, qq, kugou
+
+## 部署架构
+
+### Docker Compose
+
+```yaml
+services:
+  music-canvas:      # 前端静态网站
+    ports: 7481:3000
+
+  sync-service:      # 同步服务
+    ports: 7482:3001
+    volumes:
+      - ./data:/app/data      # KV 数据存储
+      - ./music:/app/music    # 音乐文件存储
+```
+
+### Nginx 配置
+
+- 前端: `/` → `http://127.0.0.1:7481`
+- 同步 API: `/api/` → `http://127.0.0.1:7482/` (去掉 `/api` 前缀)
+
+## 开发注意事项
+
+### 代码修改原则
+
+1. **ID 类型一致性**: 所有歌曲 ID 必须保持字符串类型,使用 `normalizeSongId()` 处理
+2. **文件名清理**: 使用 Unicode NFC 规范化 + 非法字符替换,避免跨平台问题
+3. **状态同步**: 修改 favorites/playlist 后,确保同步逻辑正确触发
+4. **API 调用**: 所有外部 API 调用通过 TuneHub API,不要直接调用各平台 API
+
+### 关键常量
+
+```javascript
+API_BASE = "https://music-dl.sayqz.com"
+SYNC_API_BASE = "/api"  // 相对路径,依赖 Nginx 代理
+SOURCES = ['netease', 'kuwo', 'qq', 'kugou']
+```
+
+### 本地开发
+
+前端无需构建,直接用浏览器打开 `index.html` 即可。如需测试同步功能:
+```bash
+cd sync-server
+node server.js  # 默认端口 3001
+```
+
+### 环境变量 (sync-server)
+
+- `DATA_DIR`: KV 数据存储目录 (默认 `./data`)
+- `MUSIC_DIR`: 音乐文件存储目录 (默认 `./music`)
+- `PORT`: 服务端口 (默认 `3001`)

+# Netease-sync 需求文档
+
+## 项目概述
+在当前目录下新建一个简单的 Node.js 项目，实现和 Navidrome 的联动，将网易云音乐歌单同步到 Navidrome。
+
+## 核心功能
+
+### 1. 歌单输入
+- 前台页面支持输入网易云音乐的歌单 ID 或分享链接
+- 支持从歌单 URL 中提取 ID（如 `https://music.163.com/#/playlist?id=123456` 提取 `123456`）
+- 只支持网易云音乐平台
+
+### 2. 歌单读取
+- 调用 TuneHub API 获取歌单详情
+- API: `GET /api/?source=netease&id={playlistId}&type=playlist`
+- 获取歌单名称、封面、描述、歌曲列表等元数据
+
+### 3. 歌曲下载
+- 调用现有的 sync-server 下载逻辑
+- 包括元数据写入（title, artist, album, cover）
+- **不创建歌单缓存 JSON 文件**，避免和主 app 混淆
+- 下载到 sync-server 的 music 目录（Navidrome 也读取此目录）
+- 如果下载失败，尝试换源（根据 api.md 支持的平台：netease, kuwo, qq）
+- **不重试**，失败则跳过
+
+### 4. Navidrome 歌单创建
+- 使用 Navidrome 的 Subsonic API
+- 在 Navidrome 中创建同名歌单
+- 将下载的歌曲加入歌单
+- 同步歌单的所有元数据（封面、描述等）
+
+### 5. 同步策略
+- **增量同步**：只新增歌曲，不删除已有歌曲
+- 通过网易云音乐歌曲 ID 判断，在本地维护一个映射表（netease_song_id -> navidrome_song_id）
+- **定时同步**：每 300 秒自动同步一次（可配置）
+- 支持手动立即同步
+
+### 6. 前端界面
+- 显示已添加的歌单列表
+- 显示每个歌单的同步状态（同步中/成功/失败）
+- 显示上次同步时间
+- 提供立即同步按钮
+- 支持添加/删除歌单
+
+## 配置项
+
+### Docker 环境变量
+- `NAVIDROME_URL`: Navidrome 服务器地址（如 `http://navidrome:4533`）
+- `NAVIDROME_USERNAME`: Navidrome 用户名
+- `NAVIDROME_PASSWORD`: Navidrome 密码
+- `SYNC_INTERVAL`: 同步间隔（秒），默认 300
+- `SYNC_SERVER_URL`: sync-server 地址（如 `http://sync-service:3001`）
+- `SYNC_SERVER_TOKEN`: sync-server 的 token（用于 KV API）
+- `TUNEHUB_API_URL`: TuneHub API 地址（如 `https://music-dl.sayqz.com`）
+
+## 技术架构
+
+### 后端
+- Node.js + Express
+- 调用 sync-server 的 KV API 传递歌曲列表
+- 调用 Navidrome Subsonic API 创建歌单
+- 定时任务：每 N 秒检查并同步歌单
+- 数据持久化：JSON 文件存储歌单列表和映射表
+
+### 前端
+- 简单的 HTML + JavaScript 页面
+- 实时显示同步状态（WebSocket 或轮询）
+- 添加/删除歌单功能
+
+## Subsonic API 集成
+
+### 认证
+所有 API 请求需要包含以下参数：
+- `u`: 用户名
+- `p`: 密码（明文或 hex 格式）
+- `v`: API 版本（如 `1.16.0`）
+- `c`: 客户端名称（如 `netease-sync`）
+
+### 主要端点
+1. **创建歌单**: `createPlaylist`
+   - 参数：`name`（歌单名称）、`songId`（歌曲 ID 列表，逗号分隔）
+   - 返回：创建的歌单 ID
+
+2. **更新歌单**: `updatePlaylist`
+   - 参数：`playlistId`（歌单 ID）、`songIdToAdd`（要添加的歌曲 ID）
+
+3. **获取歌单列表**: `getPlaylists`
+
+4. **搜索歌曲**: `search3`
+   - 参数：`query`（搜索关键词）
+   - 用于根据文件名查找 Navidrome 中的歌曲 ID
+
+## 歌曲匹配策略
+
+参考 sync-server 的去重逻辑，文件名格式为：`Artist - Name [source_id].ext`
+
+匹配步骤：
+1. 下载完成后，Navidrome 会自动扫描新歌曲
+2. 通过 `search3` 搜索文件名（如 `Artist - Name [netease_id]`）来获取 Navidrome 的歌曲 ID
+3. 将网易云音乐歌曲 ID 映射到 Navidrome 歌曲 ID
+
+## 数据结构
+
+### 歌单列表 (playlists.json)
+```json
+{
+  "playlists": [
+    {
+      "id": "netease_123456",
+      "neteaseId": "123456",
+      "name": "歌单名称",
+      "cover": "封面URL",
+      "description": "歌单描述",
+      "navidromePlaylistId": "navidrome_playlist_id",
+      "lastSyncTime": "2025-01-12T10:00:00Z",
+      "syncStatus": "success",
+      "songMapping": {
+        "netease_song_id_1": "navidrome_song_id_1",
+        "netease_song_id_2": "navidrome_song_id_2"
+      }
+    }
+  ]
+}
+```
+
+## 换源逻辑
+
+如果网易云音乐下载失败，尝试换源：
+- 优先级：kuwo -> qq
+- 每个平台只尝试一次，不重试
+
+## 错误处理
+
+- 某首歌下载失败，跳过继续下载其他歌曲
+- 不重试
+- 错误日志输出到 Docker 控制台，不存储
+
+## Navidrome 扫描延迟
+
+- Navidrome 扫描新歌曲很快，不处理延迟
+- 在添加到歌单时直接搜索歌曲 ID
