+# WeFlow HTTP API / Push 文档
+
+WeFlow 提供本地 HTTP API，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。
+
+## 启用方式
+
+在应用设置页启用 `API 服务`。
+
+- 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
+
+## 接口列表
+
+- `GET /health`
+- `GET /api/v1/health`
+- `GET /api/v1/push/messages`
+- `GET /api/v1/messages`
+- `GET /api/v1/messages/new`
+- `GET /api/v1/sessions`
+- `GET /api/v1/contacts`
+- `GET /api/v1/group-members`
+- `GET /api/v1/media/*`
+
+---
+
+## 1. 健康检查
+
+**请求**
+
+```http
+GET /health
+```
+
+或
+
+```http
+GET /api/v1/health
+```
+
+**响应**
+
+```json
+{
+  "status": "ok"
+}
+```
+
+---
+
+## 2. 主动推送
+
+通过 SSE 长连接接收新消息事件，端口与 HTTP API 共用。
+
+**请求**
+
+```http
+GET /api/v1/push/messages
+```
+
+### 说明
+
+- 需要先在设置页开启 `HTTP API 服务`
+- 同时需要开启 `主动推送`
+- 响应类型为 `text/event-stream`
+- 新消息事件名固定为 `message.new`
+- 建议接收端按 `messageKey` 去重
+
+### 事件字段
+
+- `event`
+- `sessionId`
+- `messageKey`
+- `avatarUrl`
+- `sourceName`
+- `groupName`（仅群聊）
+- `content`
+
+### 示例
+
+```bash
+curl -N "http://127.0.0.1:5031/api/v1/push/messages"
+```
+
+示例事件：
+
+```text
+event: message.new
+data: {"event":"message.new","sessionId":"xxx@chatroom","messageKey":"server:123456:1760000123:1760000123000:321:wxid_member:1","avatarUrl":"https://example.com/group.jpg","sourceName":"李四","groupName":"项目群","content":"[图片]"}
+```
+
+---
+
+## 3. 获取消息

+## 7. 访问导出媒体
+
+通过消息接口启用 `media=1` 后，接口会先把图片、语音、视频、表情导出到本地缓存目录，再返回可访问的 HTTP 地址。
+
+**请求**
+
+```http
+GET /api/v1/media/{relativePath}
+```
+
+### 示例
+
+```bash
+curl "http://127.0.0.1:5031/api/v1/media/xxx@chatroom/images/abc123.jpg"
+curl "http://127.0.0.1:5031/api/v1/media/xxx@chatroom/voices/voice_100.wav"
+curl "http://127.0.0.1:5031/api/v1/media/xxx@chatroom/videos/video_200.mp4"
+curl "http://127.0.0.1:5031/api/v1/media/xxx@chatroom/emojis/emoji_300.gif"
+```
+
+### 支持的 Content-Type
+
+| 扩展名 | Content-Type |
+| --- | --- |
+| `.png` | `image/png` |
+| `.jpg` / `.jpeg` | `image/jpeg` |
+| `.gif` | `image/gif` |
+| `.webp` | `image/webp` |
+| `.wav` | `audio/wav` |
+| `.mp3` | `audio/mpeg` |
+| `.mp4` | `video/mp4` |
+
+常见错误响应：
+
+```json
+{
+  "error": "Media not found"
+}
+```
+
+---
+
+## 8. 使用示例
+
+### PowerShell
+
+```powershell
+Invoke-RestMethod http://127.0.0.1:5031/health
+Invoke-RestMethod http://127.0.0.1:5031/api/v1/sessions
+Invoke-RestMethod "http://127.0.0.1:5031/api/v1/messages?talker=wxid_xxx&limit=10"
+Invoke-RestMethod "http://127.0.0.1:5031/api/v1/group-members?chatroomId=xxx@chatroom&includeMessageCounts=1"
+```
+
+### cURL
+
+```bash
+curl http://127.0.0.1:5031/health
+curl "http://127.0.0.1:5031/api/v1/messages?talker=wxid_xxx&chatlab=1"

+curl "http://127.0.0.1:5031/api/v1/group-members?chatroomId=xxx@chatroom"
+```
+
+### Python
+
+```python
+import requests
+
+BASE_URL = "http://127.0.0.1:5031"
+
+messages = requests.get(
+    f"{BASE_URL}/api/v1/messages",
+    params={"talker": "xxx@chatroom", "limit": 50}
+).json()
+
+members = requests.get(
+    f"{BASE_URL}/api/v1/group-members",
+    params={"chatroomId": "xxx@chatroom", "includeMessageCounts": 1}
+).json()
+
+print(messages)
+print(members)
+```
+
+---
+
+## 9. 注意事项
+
+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。
