|
||
|
||
### `GET /health`
|
||
|
||
用途:
|
||
|
||
- 检查服务是否存活。
|
||
|
||
响应示例:
|
||
|
||
```json
|
||
{

"status": "ok"
|
||

## 2. 发送消息
|
||
|
||
### `POST /messages`
|
||
|
||
用途:
|
||
|
||
- 保存单聊消息。
|
||
- 服务端会根据 `sender_user_id` 和 `peer_user_id` 自动查找或创建会话。
|
||
- `client_msg_id` 用于幂等控制。
|
||
|
||
请求体:
|
||
|
||
```json
|
||
{
|
||
"sender_user_id": 1,
|
||
"peer_user_id": 2,
|
||
"client_msg_id": "msg-20260326-0001",
|
||
"content_type": 1,
|
||
"content_text": "hello"
|
||
}
|
||
```
|
||
|
||
字段规则:
|
||
|
||
- `sender_user_id`:`int > 0`
|
||
- `peer_user_id`:`int > 0`,且不能与 `sender_user_id` 相同
|
||
- `client_msg_id`:`string`,长度 `1-64`
|
||
- `content_type`:`1=text 2=audio 3=image 4=json`
|
||
- `content_text`:`content_type=1` 时必填
|
||
- `content_json`:`content_type=4` 时必填
|
||
- `media_file_key`:`content_type=2` 或 `3` 时必填
|
||
- `media_duration_ms`:媒体时长(可选,毫秒)
|
||
|
||
