# Voice Room Client API Flow
|
||
|
||
本文定义用户进入语音房后的客户端接口调用顺序、触发条件和服务边界。本文只描述 App 侧要调用的 gateway HTTP 接口、腾讯云 IM/RTC SDK 动作，以及不能由客户端直接调用的内部守卫接口。
|
||
|
||
## Scope
|
||
|
||
| Area | Owner | Rule |
|
||
| --- | --- | --- |
|
||
| HTTP 入口 | `gateway-service` | 鉴权、profile gate、协议转换、腾讯 IM/RTC token 签发 |
|
||
| 房间业务状态 | `room-service` | Room Cell、presence、麦位、房管、snapshot、outbox |
|
||
| 房间长连接和公屏 | 腾讯云 IM SDK | 客户端登录、房间群、公屏、系统消息接收 |
|
||
| 真实音频频道 | 腾讯云 RTC SDK | 进 RTC 房、切换 audience/anchor、发音频 |
|
||
| 用户主数据 | `user-service` | 登录、资料完成状态、用户区域、push token |
|
||
|
||
关键边界：
|
||
|
||
- 客户端进入语音房必须先 `JoinRoom` 写入 room-service 业务 presence，再进 IM 群和 RTC 房。
|
||
- `room-service` 不保存客户端 socket，也不保存腾讯云 RTC 连接态。
|
||
- 腾讯云 IM 群成员关系不是业务 presence；是否允许进群、发言、签 RTC token 仍以 room-service 守卫为准。
|
||
- gateway 只使用 access token 中的 `user_id` 作为 actor，客户端不能自报 `actor_user_id`、`owner_user_id`、`host_user_id`。
|
||
- 所有 `/api/v1` 业务响应使用 `{code,message,request_id,data}` envelope。
|
||
|
||
## Minimal Enter Room Flow

end
|

```
|
||
|
||
### Required Order
|
||
|
||
| Step | Interface | Required | Reason |
|
||
| --- | --- | --- | --- |
|
||
| 1 | `GET /api/v1/im/usersig` | yes | 用户级 IM 登录票据，可在 App 启动后预取并按 TTL 复用 |
|
||
| 2 | Tencent IM SDK `login` | yes | 客户端先建立 IM 身份，房间群仍等 JoinRoom 成功后再进 |
|
||
| 3 | `GET /api/v1/rooms/me` | yes for Mine top card | 直接读取 owner 房间权威元数据，不依赖发现页投影 |
|
||
| 4 | `GET /api/v1/rooms/feeds?tab=visited\|friend\|following` | yes for Mine lists | Mine 列表 tab；`visited` 由 JoinRoom 成功写入，`friend/following` 由 gateway 先查 user-service 关系，再让 room-service 返回这些关系用户的 active 房间卡片 |
|
||
| 5 | `POST /api/v1/rooms/join` | yes | 建立业务 presence，并返回首屏房间数据和内嵌 RTC token |
|
||
| 6 | Tencent IM SDK `joinGroup(im_group_id)` | yes | 必须在 JoinRoom 成功后执行，IM 回调守卫会校验 room-service presence |
|
||
| 7 | Tencent RTC SDK `enterRoom` | yes for voice room audio | 使用 JoinRoom 响应里的 `rtc.token` 进入真实音频频道旁听 |
|
||
| 8 | `POST /api/v1/rooms/heartbeat` | yes | 刷新业务 presence，避免 stale timeout |
|
||
| 9 | `GET /api/v1/rooms/{room_id}/detail` | optional after join/restore | 详情页聚合包；用于 JoinRoom 后补偿刷新、回前台、设计稿首屏重绘 |
|
||
| 10 | `GET /api/v1/rooms/{room_id}/gift-panel` | lazy on gift button | 打开礼物面板时再拉，不放进房间首屏 |
|
||
| 11 | `GET /api/v1/rooms/{room_id}/online-users` | lazy on online count | 点击右上角在线人数时分页拉取 |
|
||
|
||
如果 JoinRoom 响应里的 `rtc.available=false`，客户端可以先展示房间页并重试 `POST /api/v1/rtc/token`；RTC 失败不能回滚已经成功的业务 presence。
|
||
|
||
### Mine Feed Cache Boundary
|
||
|
||
当前 `friend/following` 不强制加 Redis。原因是关注、取关、同意好友和删除好友都要求列表立即反映关系事实；首版直接读 user-service MySQL 关系表，再查 room-service active 房间卡片，正确性更直接。
|
||
|
||
后续可以加 Redis 的位置：
|
||
|
||
- `hot/new` 公共列表：room-service 用 Redis ZSET 缓存排序 room_id，miss 后回源 `room_list_entries`。
|
||
- 房间卡片短 TTL 缓存：key 可按 `app_code + region_id + room_id`，但 MySQL `room_list_entries` 仍是事实来源。
|
||
- `friend/following` 关系 ID 短 TTL 缓存：只能放在 gateway 或 user-service 读优化层，`follow/unfollow/accept/delete` 成功后必须主动失效。
|
||
- `visited` room_id 列表缓存：可以由 JoinRoom 成功后刷新，Redis 写失败不能影响 JoinRoom。
|
||
|
||
不建议首版缓存 `friend/following` 完整房间卡片列表。这个列表同时依赖 user-service 关系事实、room-service 房间 active 状态、区域过滤和搜索条件，失效面较大；先保持同步查询，等 QPS 或延迟数据证明需要缓存再加。
|
||
|
||
## Core Interfaces
|
||
|
||
### Join Room
|
||
|
||
```http
|
||
POST /api/v1/rooms/join
|
||
Authorization: Bearer <access_token>
|
||
Content-Type: application/json

},
|

"server_time_ms": 1778000000000
|
||
}
|
||
```
|
||
|
||
Rules:
|
||
|
||
- `room_id` 必须来自房间列表、分享或恢复接口，不能由客户端拼业务含义。
|
||
- `command_id` 由客户端按用户动作生成，用于房间命令幂等；重试同一次进房必须复用同一个值。
|
||
- `role` 只作为展示默认值，不能通过自报 `admin/host/owner` 获得权限。
|
||
- `im.group_id` 当前等于 `room_id`，但客户端必须使用服务端返回值，不能硬编码映射规则。
|
||
- JoinRoom 成功后才能调用腾讯 IM SDK `joinGroup`；列表里的 `im_group_id` 只用于准备，不代表入群授权。
|
||
- JoinRoom 会尝试内嵌签发 RTC token；签发失败时返回 `rtc.available=false`，客户端可以继续展示房间并单独重试 `/api/v1/rtc/token`。
|
||
|
||
### Room Detail
|
||
|
||
```http
|
||
GET /api/v1/rooms/{room_id}/detail
|
||
Authorization: Bearer <access_token>
|
||
```
|
||
|
||
Response `data`:
|
||
|
||
```json
|
||
{
|
||
"room": {},
|
||
"viewer": {},
|
||
"seats": [],
|
||
"rank_top": [],
|
||
"online_count": 30,
|
||
"permissions": {},
|
||
"profiles": [],
|
||
"im": {},
|
||
"rtc": {}
|
||
}
|
||
```
|
||
|
||
Rules:
|
||
|
||
- `detail` 只读 Room Cell/snapshot，不刷新 heartbeat，不隐式进房。
|
||
- viewer 必须仍在 room-service presence 内；未进房、被踢或被 ban 返回 `PERMISSION_DENIED`。
|
||
- `permissions.can_close_room` 表示设计稿右上角电源按钮可用，但当前语义是“退出房间”，不是关闭房间生命周期。
|
||
- `profiles` 只返回首屏需要的 owner、host、viewer、麦位用户和榜单 top 用户。完整在线用户资料走在线用户分页或 `users/room-display-profiles:batch`。
|
||
|
||
### Online Users
|
||
|
||
```http
|
||
GET /api/v1/rooms/{room_id}/online-users?page=1&page_size=50
|
||
Authorization: Bearer <access_token>
|
||
```
|
||
|
||
Response `data`:
|
||
|
||
```json
|
||
{
|
||
"items": [
|
||
{
|
||
"user_id": "10002",
|
||
"role": "audience",
|
||
"last_seen_at_ms": 1778000000000,
|
||
"profile": {}
|
||
}
|
||
],
|
||
"total": 30,
|
||
"page": 1,
|
||
"page_size": 50,
|
||
"server_time_ms": 1778000000000
|
||
}
|
||
```
|
||
|
||
Rules:
|
||
|
||
- 该接口读 `room_user_presence` 分页投影，不拉完整 `RoomSnapshot` 做列表分页。
|
||
- `page_size` 默认 50，服务端最大 100。
|
||
- 用户展示资料失败不影响在线列表主数据，客户端可用 `GET /api/v1/users/room-display-profiles:batch` 补偿。
|
||
|
||
### Gift Panel
|
||
|
||
```http
|
||
GET /api/v1/rooms/{room_id}/gift-panel
|
||
Authorization: Bearer <access_token>
|
||
```
|
||
|
||
Response `data`:
|
||
|
||
```json
|
||
{
|
||
"coin_balance": 1123123,
|
||
"recipients": [],
|
||
"tabs": [],
|
||
"gifts": [],
|
||
"quantity_presets": [1, 9, 99, 999]
|
||
}
|
||
```
|
||
|
||
Rules:
|
||
|
||
- 打开礼物面板时再请求，不放进 `rooms/detail`，避免房间首屏每次都查钱包和礼物大列表。
|
||
- `gifts` 来自 wallet-service 礼物配置，按房间 `visible_region_id` 过滤。
|
||
- `recipients` 首版包含麦上用户；超过一个麦上用户时附带 `target_type=all_mic` 占位。
|
||
- `coin_balance` 只查 `COIN` 余额；余额不足时送礼接口仍以 wallet-service 扣费结果为准。
|
||
|
||
### Room Display Profiles
|
||
|
||
```http
|
||
GET /api/v1/users/room-display-profiles:batch?user_ids=10001,10002
|
||
Authorization: Bearer <access_token>
|
||
```
|
||
|
||
Response `data`:
|
||
|
||
```json
|
||
{
|
||
"profiles": [
|
||
{
|
||
"user_id": "10002",
|
||
"username": "Jack",
|
||
"avatar": "https://cdn.example/avatar.png",
|
||
"display_user_id": "123456",
|
||
"vip": {},
|
||
"level": {},
|
||
"badges": [],
|
||
"avatar_frame": {},
|
||
"vehicle": {},
|
||
"charm": 10
|
||
}
|
||
]
|
||
}
|
||
```
|
||
|
||
Rules:
|
||
|
||
- 该接口专门服务房间麦位、公屏和礼物动效展示；不要复用“我的页”或用户主页重接口。
|
||
- 当前已接入用户基础资料，`vip/level/badges/avatar_frame/vehicle/charm` 保持稳定字段，后续接入对应 read model 后填充。
|
||
|
||
### IM UserSig
|
||
|
||
```http
|
||
GET /api/v1/im/usersig
|
||
Authorization: Bearer <access_token>
|
||
```
|
||
|
||
Response `data`:
|
||
|
||
```json
|
||
{
|
||
"sdk_app_id": 20036101,
|
||
"user_id": "10001",
|
||
"user_sig": "xxx",
|
||
"expire_at_ms": 1778086400000,
|
||
"join_groups": [
|
||
{
|
||
"group_id": "hy_lalu_bc_g",
|
||
"type": "global_broadcast"
|
||
},
|
||
{
|
||
"group_id": "hy_lalu_bc_r_1001",
|
||
"type": "region_broadcast",
|
||
"region_id": 1001
|
||
}
|
||
]
|
||
}
|
||
```
|
||
|
||
Rules:
|
||
|
||
- 当前 gateway 路由是 `GET /api/v1/im/usersig`。
|
||
- `user_id` 是内部不可变长 `user_id` 的十进制字符串，必须直接作为腾讯云 IM identifier。
|
||
- UserSig 只用于腾讯云 IM SDK 登录，不用于本仓库鉴权。
|
||
- 未完成资料用户会被 profile gate 拒绝。
|
||
|
||
Client SDK action:
|
||
|
||
```text
|
||
Tencent IM SDK login(user_id, user_sig)
|
||
Tencent IM SDK joinGroup(join_response.im.group_id)
|
||
```
|
||
|
||
### RTC Token
|
||
|
||
`POST /api/v1/rtc/token` 是 JoinRoom 内嵌签发失败、token 过期或 RTC 重连时的补偿入口；首次进房应优先使用 JoinRoom 响应里的 `rtc.token`。
|
||
|
||
```http
|
||
POST /api/v1/rtc/token
|
||
Authorization: Bearer <access_token>
|
||
Content-Type: application/json
|
||
```
|
||
|
||
Request:
|
||
|
||
```json
|
||
{
|
||
"room_id": "lalu_xxx"
|
||
}
|
||
```
|
||
|
||
Response `data`:
|
||
|
||
```json
|
||
{
|
||
"sdk_app_id": 20036101,
|
||
"user_id": "10001",
|
||
"rtc_user_id": "10001",
|
||
"user_sig": "xxx",
|
||
"expire_at_ms": 1778007200000,
|
||
"room_id": "lalu_xxx",
|
||
"rtc_room_id": "lalu_xxx",
|
||
"rtc_room_id_type": "string",
|
||
"str_room_id": "lalu_xxx",
|
||
"app_scene": "voice_chat_room",
|
||
"role": "audience"
|
||
}
|
||
```
|
||
|
||
Rules:
|
||
|
||
- gateway 会先调用 room-service `VerifyRoomPresence`，用户不在房间、被踢、被 ban 时不会签发 RTC token。
|
||
- 当前只支持 TRTC `strRoomId`，客户端不能把 `room_id` 转为数字 `roomId`。
|
||
- 当前 token 返回 `role=audience`；上麦成功后由客户端切 `anchor` 并确认发流。
|
||
- token 过期时重新调用该接口，不使用 refresh token。
|
||
|
||
Client SDK action:
|
||
|
||
```text
|
||
Tencent RTC SDK enterRoom(strRoomId=resp.str_room_id, userId=resp.rtc_user_id, role=audience)
|
||
```
|
||
|
||
### Update Room Profile
|
||
|
||
房主在房间内修改房间资料和座位数时调用：
|
||
|
||
```http
|
||
POST /api/v1/rooms/profile/update
|
||
Authorization: Bearer <access_token>
|
||
Content-Type: application/json
|
||
```
|
||
|
||
Request:
|
||
|
||
```json
|
||
{
|
||
"room_id": "lalu_xxx",
|
||
"command_id": "cmd_profile_<room_id>_<user_id>_<nonce>",
|
||
"room_name": "Live Room",
|
||
"room_avatar": "https://cdn.example/room.png",
|
||
"room_description": "welcome",
|
||
"seat_count": 20
|
||
}
|
||
```
|
||
|
||
Rules:
|
||
|
||
- 只有当前在房间内的 owner 可以执行。
|
||
- `room_name`、`room_avatar`、`room_description`、`seat_count` 都是可选字段；客户端只传本次要修改的字段。
|
||
- `seat_count` 只能传后台已启用的 `10/15/20/25/30` 子集，当前默认配置全部启用。
|
||
- 创建房间可以省略 `seat_count` 使用后台默认值；修改资料时不能传 `0`。
|
||
- 缩小座位数时，被删除的高编号麦位必须全部空闲且未锁，否则返回 `conflict`，客户端需要先处理麦位再重试。
|
||
- 成功响应返回最新 `room` 和 `seats`，客户端直接刷新房间标题、头像、简介和麦位列表。
|
||
- 成功后房间系统消息事件名为 `room_profile_updated`。
|
||
|
||
### Heartbeat
|
||
|
||
```http
|
||
POST /api/v1/rooms/heartbeat
|
||
Authorization: Bearer <access_token>
|
||
Content-Type: application/json
|
||
```
|
||
|
||
Request:
|
||
|
||
```json
|
||
{
|
||
"room_id": "lalu_xxx",
|
||
"command_id": "cmd_heartbeat_<room_id>_<user_id>_<tick>"
|
||
}
|
||
```
|
||
|
||
Rules:
|
||
|
||
- 只刷新已经存在的业务 presence，不能替代 JoinRoom。
|
||
- 用户已经离房、被踢或房间关闭时，客户端应停止心跳并清理本地房间态。
|
||
- 心跳间隔由客户端配置控制，但必须小于 room-service 的 presence stale 窗口。
|
||
|
||
### Leave Room
|
||
|
||
```http
|
||
POST /api/v1/rooms/leave
|
||
Authorization: Bearer <access_token>
|
||
Content-Type: application/json
|

```
|
||
|

Request:
|
||
|

```json
|

"room_id": "lalu_xxx",
|
||
"command_id": "cmd_leave_<room_id>_<user_id>_<nonce>"
|

}
|
||
```
|
||
|
||
Rules:
|
||
|
||
- 主动关闭房间页、切换账号、被客户端确认退出时调用。
|
||
- 如果用户在麦上，LeaveRoom 会释放麦位。
|
||
- LeaveRoom 后客户端必须停止 heartbeat、退出 RTC 房、退出或忽略 IM 房间群消息。

|
||
## Mic Flow
|
||
|
||
### Mic Up
|
||
|
||
```http
|
||
POST /api/v1/rooms/mic/up
|
||
Authorization: Bearer <access_token>
|
||
Content-Type: application/json
|
||
```
|
||
|
||
Request:
|
||
|
||
```json
|
||
{
|
||
"room_id": "lalu_xxx",
|
||
"command_id": "cmd_mic_up_<room_id>_<user_id>_<nonce>",
|
||
"seat_no": 1
|
||
}
|
||
```
|
||
|
||
Response `data`:
|
||
|
||
```json
|
||
{
|
||
"result": {},
|
||
"seat_no": 1,
|
||
"mic_session_id": "mic_xxx",
|
||
"publish_deadline_ms": 1778000015000,
|
||
"room": {}
|
||
}
|
||
```
|
||
|
||
Client actions after success:
|
||
|
||
1. 保存 `mic_session_id`、`room.version` 和 `publish_deadline_ms`。
|
||
2. 确保已有 RTC token；没有或过期则调用 `POST /api/v1/rtc/token`。
|
||
3. RTC SDK 切换 `anchor`。
|
||
4. RTC SDK 调 `startLocalAudio`。
|
||
5. SDK 本地发流成功后调用 `POST /api/v1/rooms/mic/publishing/confirm`。
|
||
|
||
Rules:
|
||
|
||
- `MicUp` 成功只代表业务麦位占用成功，不代表 RTC 已经发布音频成功。
|
||
- 服务端状态先进入 `pending_publish`。
|
||
- 超过 `publish_deadline_ms` 未确认，room-service 会自动 MicDown，reason 为 `publish_timeout`。
|
||
|
||
### Confirm Mic Publishing
|
||
|
||
```http
|
||
POST /api/v1/rooms/mic/publishing/confirm
|
||
Authorization: Bearer <access_token>
|
||
Content-Type: application/json
|
||
```
|
||
|
||
Request:
|
||
|
||
```json
|
||
{
|
||
"room_id": "lalu_xxx",
|
||
"command_id": "cmd_confirm_publish_<room_id>_<user_id>_<nonce>",
|
||
"target_user_id": 0,
|
||
"mic_session_id": "mic_xxx",
|
||
"room_version": 12,
|
||
"event_time_ms": 1778000001000,
|
||
"source": "client"
|
||
}
|
||
```
|
||
|
||
Rules:
|
||
|
||
- `target_user_id=0` 表示确认当前 actor；RTC webhook 路径才需要显式 target。
|
||
- `mic_session_id` 必须等于当前麦位会话。
|
||
- `room_version` 和 `event_time_ms` 用于丢弃旧事件，避免旧 audience/leave 事件清理新会话。
|
||
- 成功后麦位 `publish_state=publishing`。
|
||
|
||
### Mic Down
|
||
|
||
```http
|
||
POST /api/v1/rooms/mic/down
|
||
Authorization: Bearer <access_token>
|
||
Content-Type: application/json
|
||
```
|
||
|
||
Request:
|
||
|
||
```json
|
||
{
|
||
"room_id": "lalu_xxx",
|
||
"command_id": "cmd_mic_down_<room_id>_<user_id>_<nonce>",
|
||
"target_user_id": 0,
|
||
"reason": "user_action"
|
||
}
|
||
```
|
||
|
||
Rules:
|
||
|
||
- 普通用户下自己麦时 `target_user_id` 可传 0 或自己 user_id。
|
||
- 房管下别人麦时传目标用户 `target_user_id`。
|
||
- 客户端收到成功响应或房间系统消息后必须停止本地音频并切回 `audience`。
|
||
|
||
### Change Mic Seat
|
||
|
||
```http
|
||
POST /api/v1/rooms/mic/change
|
||
Authorization: Bearer <access_token>
|
||
Content-Type: application/json
|
||
```
|
||
|
||
Request:
|
||
|
||
```json
|
||
{
|
||
"room_id": "lalu_xxx",
|
||
"command_id": "cmd_change_mic_<room_id>_<actor_user_id>_<nonce>",
|
||
"target_user_id": 10002,
|
||
"seat_no": 2
|
||
}
|
||
```
|
||
|
||
Rules:
|
||
|
||
- 换麦位只更新业务麦位和 UI，不需要重新进入 RTC。
|
||
- 如果 target 当前在发流，客户端继续保持 RTC 上行。
|
||
|
||
## Room Management APIs
|
||
|
||
这些接口只允许有权限的 owner/host/admin 调用；gateway 不判断权限，最终由 room-service Room Cell 判断。
|
||
|
||
| Interface | Body | Result |
|
||
| --- | --- | --- |
|
||
| `POST /api/v1/rooms/mic/lock` | `room_id, command_id, seat_no, locked` | 锁/解锁麦位 |
|
||
| `POST /api/v1/rooms/mic/mute` | `room_id, command_id, target_user_id, muted` | 修改麦克风静音状态；该状态会同步给房间其他用户 |
|
||
| `POST /api/v1/rooms/chat/enabled` | `room_id, command_id, enabled` | 开/关公屏，影响发言守卫 |
|
||
| `POST /api/v1/rooms/admin/set` | `room_id, command_id, target_user_id, is_admin` | 设置或取消房管 |
|
||
| `POST /api/v1/rooms/host/transfer` | `room_id, command_id, target_user_id` | 转移主持人 |
|
||
| `POST /api/v1/rooms/user/mute` | `room_id, command_id, target_user_id, muted, reason` | 禁言或解禁 |
|
||
| `POST /api/v1/rooms/user/kick` | `room_id, command_id, target_user_id, reason` | 踢人并 ban，释放 presence 和麦位 |
|
||
| `POST /api/v1/rooms/user/unban` | `room_id, command_id, target_user_id, reason` | 解除房间 ban |
|
||
| `POST /api/v1/rooms/close` | `room_id, command_id` | 设计稿电源按钮：当前用户退出房间，不关闭房间 |
|
||
|
||
Management event handling:
|
||
|
||
- 管理动作成功后，room-service 写 command log、snapshot 和 outbox。
|
||
- 客户端应通过腾讯云 IM 房间系统消息更新 UI。
|
||
- 如果本地 UI 状态和系统消息冲突，以最新 room snapshot 和 `room_version` 为准。
|
||
|
||
## Gift And Interaction
|
||
|
||
```http
|
||
POST /api/v1/rooms/gift/send
|
||
Authorization: Bearer <access_token>
|
||
Content-Type: application/json
|
||
```
|
||
|
||
Request:
|
||
|
||
```json
|
||
{
|
||
"room_id": "lalu_xxx",
|
||
"command_id": "cmd_send_gift_<room_id>_<user_id>_<nonce>",
|
||
"target_type": "user",
|
||
"target_user_ids": [10002],
|
||
"gift_id": "rose",
|
||
"gift_count": 1
|
||
}
|
||
```
|
||
|
||
Rules:
|
||
|
||
- `SendGift` 必须先由 wallet-service 扣费成功，再落房间表现。
|
||
- 旧客户端的 `target_user_id` 仍兼容；新客户端统一传 `target_type + target_user_ids`。
|
||
- 当前已支持 `target_type=user`；`all_mic/all_room/couple` 先保留协议字段，等账务拆单和房间表现策略补齐后开放。
|
||
- 房间表现、热度、本地榜通过 room snapshot 和房间系统消息同步。
|
||
- 公屏文本消息不走 gateway HTTP；客户端使用腾讯云 IM 群消息。
|
||
|
||
## Restore And Reconnect
|
||
|
||
### Current Room
|
||
|
||
```http
|
||
GET /api/v1/rooms/current
|
||
Authorization: Bearer <access_token>
|
||
```
|
||
|
||
Response `data`:
|
||
|
||
```json
|
||
{
|
||
"has_current_room": true,
|
||
"room_id": "lalu_xxx",
|
||
"room_version": 12,
|
||
"role": "audience",
|
||
"mic_session_id": "",
|
||
"publish_state": "",
|
||
"need_join_im_group": true,
|
||
"need_rtc_token": false,
|
||
"server_time_ms": 1778000000000
|
||
}
|
||
```
|
||
|
||
Client restore rules:
|
||
|
||
| Response | Client Action |
|
||
| --- | --- |
|
||
| `has_current_room=false` | 清理本地房间态，不展示恢复入口 |
|
||
| `need_join_im_group=true` | 调 `GET /api/v1/im/usersig`，重新登录 IM 并 join group |
|
||
| `need_rtc_token=true` | 调 `POST /api/v1/rtc/token`，重新进入 RTC |
|
||
| `publish_state=pending_publish` | 重新执行 SDK 发流并确认当前 `mic_session_id` |
|
||
| `publish_state=publishing` | 确认本地 RTC 上行是否仍存在；不确定时重新发流并确认 |
|
||
|
||
`rooms/current` 是只读恢复探测，不会隐式 JoinRoom，不刷新 heartbeat，也不改变 Room Cell。
|
||
|
||
### Reconnect Order
|
||
|
||
1. access token 有效时先调 `GET /api/v1/rooms/current`。
|
||
2. 如果 `has_current_room=false`，回房间列表或主界面。
|
||
3. 如果 `has_current_room=true`，先恢复 IM，再恢复 RTC。
|
||
4. 如果用户原本在麦上，必须使用返回的 `mic_session_id` 继续确认或等待服务端超时下麦。
|
||
5. 恢复成功后恢复 `POST /api/v1/rooms/heartbeat` 定时器。
|
||
|
||
## Server Callback Boundaries
|
||
|
||
客户端不要直接调用这些接口或内部 RPC：
|
||
|
||
| Interface | Caller | Purpose |
|
||
| --- | --- | --- |
|
||
| `POST /api/v1/tencent-im/callback` | Tencent IM | 入群、发言等服务端回调入口 |
|
||
| `POST /api/v1/tencent-rtc/callback` | Tencent RTC | RTC 音频事件回调入口 |
|
||
| `room-service.VerifyRoomPresence` | gateway / callback | 判断用户是否仍在房间、是否被 ban |
|
||
| `room-service.CheckSpeakPermission` | gateway / callback | 判断用户是否允许发公屏 |
|
||
|
||
客户端只消费这些回调产生的房间系统消息和最新 snapshot，不直接操作内部守卫。
|
||
|
||
## Error Handling
|
||
|
||
| Error | Meaning | Client Action |
|
||
| --- | --- | --- |
|
||
| `UNAUTHORIZED` / `AUTH_REQUIRED` | access token 无效 | refresh 成功后重试；refresh 失败回登录 |
|
||
| `PROFILE_REQUIRED` | 资料未完成 | 跳资料补全页，不能进入房间 |
|
||
| `NOT_FOUND` | 房间或用户事实不存在 | 清本地目标房间，回列表 |
|
||
| `ROOM_CLOSED` | 房间已关闭 | 清房间态，回列表 |
|
||
| `PERMISSION_DENIED` | 被踢、被 ban、无权限 | 停止对应操作，按系统消息更新 UI |
|
||
| `CONFLICT` | 麦位占用、命令冲突、状态冲突 | 拉最新 snapshot 或等待房间系统消息修正 |
|
||
| `UPSTREAM_ERROR` | 内部服务或腾讯云依赖异常 | 保留本地登录态，展示重试 |
|
||
|
||
不要因为普通网络失败或 5xx 清空登录态。只有 refresh 明确失败、session revoked 或用户主动 logout 才清 token。
|
||
|
||
## Room Snapshot Sync
|
||
|
||
当前客户端拿完整房间状态的来源：
|
||
|
||
- `JoinRoom` 响应里的 room snapshot。
|
||
- `GET /api/v1/rooms/{room_id}/detail` 的首屏聚合包。
|
||
- 房间命令响应里的 room snapshot。
|
||
- 腾讯云 IM 房间系统消息。
|
||
- `rooms/current` 的恢复摘要。
|
||
- `GET /api/v1/rooms/snapshot?room_id=<room_id>` 主动同步接口。
|
||
|
||
```http
|
||
GET /api/v1/rooms/snapshot?room_id=<room_id>
|
||
```
|
||
|
||
该接口只读 Room Cell/snapshot，不刷新 presence，不隐式 JoinRoom，不替代 heartbeat。gateway 使用 access token user_id 作为 viewer，room-service 要求 viewer 仍在该房间；未进房、被踢或被 ban 的用户不能读取完整在线用户和麦位快照。
