+# API 服务修改说明
+
+## 修改概述
+
+根据要求，仅首页的推荐和搜索功能使用 `back_jwlll` 服务，其他功能使用已有的其他后端服务。
+
+## 服务分工
+
+### JWLLL 服务 (端口 5000)
+**仅用于首页推荐和搜索功能**
+- 搜索内容 (`/search`)
+- 获取用户标签 (`/user_tags`)
+- 标签推荐 (`/recommend_tags`)
+- 协同过滤推荐 (`/user_based_recommend`)
+
+### WZY 服务 (端口 5714)
+**用于帖子相关功能**
+- 帖子详情查看 (`/posts/{id}`)
+- 帖子创建/更新/删除 (`/posts`)
+- 点赞功能 (`/posts/{id}/like`)
+- 评论功能 (`/posts/{id}/comments`)
+
+### LJC 服务 (端口 5715)
+**用于用户相关功能**
+- 用户信息管理 (`/api/user/{id}`)
+- 关注功能 (`/api/follow/{id}`)
+- 收藏功能 (`/api/user/{id}/favorites`)
+
+### TRM 服务 (端口 5713)
+**用于审核相关功能**
+- 帖子审核 (`/areview`)
+- 管理员功能 (`/apostlist`)
+
+## 修改的文件
+
+### 1. `/src/api/search_jwlll.js`
+- **修改内容**: 重构API调用，推荐搜索功能继续使用JWLLL服务，其他功能重定向到相应服务
+- **主要变更**:
+  - 搜索和推荐API仍使用 `http://127.0.0.1:5000`
+  - 帖子详情、点赞、评论、上传功能改用 WZY 服务 `http://10.126.59.25:5714`
+  - 添加数据格式适配逻辑
+
+### 2. `/src/api/posts_api.js` (新增)
+- **作用**: 提供统一的帖子相关API接口
+- **功能**: 整合不同后端服务的帖子和用户功能
+
+## 数据格式适配
+
+### 评论数据适配
+- **WZY服务返回**: `{id, user_id, content, created_at, replies}`
+- **前端期望**: `{id, user_name, content, create_time}`
+- **适配方案**: 在 `getComments` 方法中进行字段映射
+
+### 帖子上传适配
+- **前端数据**: `{title, content, tags, category, type, media_files}`
+- **WZY服务期望**: `{title, content, type, media_urls, status}`
+- **适配方案**: 在 `uploadPost` 方法中进行数据转换
+
+## 影响的组件
+
+### 自动适配的组件
+- `HomeFeed.jsx` - 推荐和搜索功能，继续使用JWLLL服务
+- `PostDetailJWLLL.jsx` - 帖子详情、点赞、评论功能，自动切换到WZY服务
+- `UploadPageJWLLL.jsx` - 帖子上传功能，自动切换到WZY服务
+
+### 使用新API的组件
+如需要，其他组件可以导入 `posts_api.js` 来使用统一的帖子和用户API。
+
+## 注意事项
+
+1. **标签功能限制**: WZY服务暂不完全支持标签功能，上传帖子时标签信息会被忽略
+2. **用户名显示**: 评论中的用户名使用 `用户{user_id}` 格式生成
+3. **服务兼容性**: 确保所有后端服务都正常运行且端口配置正确
+4. **错误处理**: 各服务的错误响应格式可能不同，前端已添加通用错误处理
+
+## 测试建议
+
+### 测试文件
+提供了 `test_api.js` 文件来验证API服务分工是否正确：
+
+```javascript
+import { runAllTests } from './test_api.js'
+
+// 运行所有测试
+runAllTests()
+```
+
+### 手动测试步骤
+1. **首页搜索测试**
+   - 在首页搜索框输入关键词
+   - 验证搜索结果来自 JWLLL 服务
+   - 测试推荐功能是否正常
+
+2. **帖子详情测试**
+   - 点击帖子进入详情页
+   - 验证帖子数据来自 WZY 服务
+   - 测试点赞、评论功能
+
+3. **帖子上传测试**
+   - 使用上传页面发布新帖子
+   - 验证上传请求发送到 WZY 服务
+   - 确认数据格式转换正确
+
+### 服务状态检查
+确保以下服务正常运行：
+- JWLLL 服务: `curl http://127.0.0.1:5000/word2vec_status`
+- WZY 服务: `curl http://10.126.59.25:5714/posts`
+- LJC 服务: `curl http://10.126.59.25:5715/api/current-user`
+- TRM 服务: `curl http://10.126.59.25:5713/health` (如果有)
