-# WeFlow HTTP API 接口文档
+# WeFlow HTTP API / Push 文档
 
-WeFlow 提供 HTTP API 服务，支持通过 HTTP 接口查询消息数据，支持 [ChatLab](https://github.com/nichuanfang/chatlab-format) 标准化格式输出。
+WeFlow 提供本地 HTTP API（已支持GET 和 POST请求），便于外部脚本或工具读取聊天记录、会话、联系人、群成员和导出的媒体文件；也支持在检测到新消息后通过固定 SSE 地址主动推送消息事件。
 
-## 启用 API 服务
+## 启用方式
 
-在设置页面 → API 服务 → 点击「启动服务」按钮。
+在应用设置页启用 `API 服务`。
 
-默认端口：`5031`
+- 默认监听地址：`127.0.0.1`
+- 默认端口：`5031`
+- 基础地址：`http://127.0.0.1:5031`
+- 可选开启 `主动推送`，检测到新收到的消息后会通过 `GET /api/v1/push/messages` 推送给 SSE 订阅端
 
-## 基础地址
+**状态记忆**：API 服务和主动推送的状态及端口会自动保存，重启 WeFlow 后会自动恢复运行。

+## 鉴权规范
 
----
+**鉴权规范 (Access Token)** 除健康检查接口外，所有 `/api/v1/*` 接口均受 Token 保护。支持三种传参方式（任选其一）：
+
+1. **HTTP Header (推荐)**: `Authorization: Bearer <您的Token>`
+2. **Query 参数**: `?access_token=<您的Token>`（SSE 长连接推荐此方式）
+3. **JSON Body**: `{"access_token": "<您的Token>"}`（仅限 POST 请求）

-## 使用示例
+## 7. 朋友圈接口
+
+### 7.1 获取朋友圈时间线
+
+```http
+GET /api/v1/sns/timeline
+```
+
+参数：
+
+| 参数 | 类型 | 必填 | 说明 |
+| --- | --- | --- | --- |
+| `limit` | number | 否 | 返回数量，默认 20，范围 `1~200` |
+| `offset` | number | 否 | 偏移量，默认 0 |
+| `usernames` | string | 否 | 发布者过滤，逗号分隔，如 `wxid_a,wxid_b` |
+| `keyword` | string | 否 | 关键词过滤（正文） |
+| `start` | string | 否 | 开始时间，支持 `YYYYMMDD` 或秒/毫秒时间戳 |
+| `end` | string | 否 | 结束时间，支持 `YYYYMMDD` 或秒/毫秒时间戳 |
+| `media` | number | 否 | 是否返回可直接访问的媒体地址，默认 `1` |
+| `replace` | number | 否 | `media=1` 时，是否用解析地址覆盖 `media.url/thumb`，默认 `1` |
+| `inline` | number | 否 | `media=1` 时，是否内联返回 `data:` URL，默认 `0` |
+
+示例：
+
+```bash
+curl "http://127.0.0.1:5031/api/v1/sns/timeline?limit=5"
+curl "http://127.0.0.1:5031/api/v1/sns/timeline?usernames=wxid_a,wxid_b&keyword=旅行"
+curl "http://127.0.0.1:5031/api/v1/sns/timeline?limit=3&media=1&replace=1"
+curl "http://127.0.0.1:5031/api/v1/sns/timeline?limit=3&media=1&inline=1"
+```
+
+媒体字段说明（`media=1`）：
+
+- `media[].url/thumb`：你应该优先直接使用的字段。
+- `replace=1`（默认）时，`media[].url/thumb` 会直接被替换成可访问地址，等价于 `resolvedUrl/resolvedThumbUrl`。
+- `replace=0` 时，`media[].url/thumb` 仍保留微信原始地址；这时再结合下面的 `raw/proxy/resolved` 字段自己决定用哪一个。
+- `media[].rawUrl/rawThumb`：原始朋友圈地址
+- `media[].proxyUrl/proxyThumbUrl`：可直接访问的代理地址
+- `media[].resolvedUrl/resolvedThumbUrl`：最终可用地址（`inline=1` 时可能是 `data:` URL）
+- `media[].token/key/encIdx`：微信源数据里的访问/解密参数。通常不需要你自己处理；如果你手动调用 `/api/v1/sns/media/proxy`，把当前条目的 `url` 和 `key` 原样传回即可。
+- `media[].livePhoto`：实况图的视频部分。外层 `media[].url/thumb` 仍是封面图，`livePhoto` 内部会再提供一组自己的 `url/thumb/raw*/proxy*/resolved*` 字段。
+- `media=0` 时，不会补充 `raw*/proxy*/resolved*`，接口只返回原始 `url/thumb` 以及源字段（如 `key/token/encIdx`）。

-## 注意事项
+## 10. 注意事项
 
-1. API 仅监听本地地址 `127.0.0.1`，不对外网开放
-2. 需要先连接数据库才能查询数据
-3. 时间参数格式为 `YYYYMMDD`（如 20260205）
-4. 支持 CORS，可从浏览器前端直接调用
+1. API 仅监听本机 `127.0.0.1`，不对外网开放。
+2. 使用前需要先在 WeFlow 中完成数据库连接。
+3. `start` 和 `end` 支持 `YYYYMMDD` 与时间戳；纯 `YYYYMMDD` 的 `end` 会扩展到当天 `23:59:59`。
+4. 群成员的 `groupNickname` 依赖微信源数据；源数据缺失时不会自动补出。
+5. 媒体访问链接只有在对应消息已经通过 `media=1` 导出后才可访问。
