# WebSocket Service — 实现细节
|
||||
|
||||
> 主流程见 SKILL.md,本文档为服务端配置、连接管理器、Controller、推送服务、前端客户端的完整代码。
|
||||
|
||||
## 服务端配置
|
||||
|
||||
```php
|
||||
// config/autoload/server.php
|
||||
[
|
||||
'name' => 'ws',
|
||||
'type' => Server::SERVER_WEBSOCKET,
|
||||
'host' => '0.0.0.0',
|
||||
'port' => (int) env('WEBSOCKET_PORT', 9502),
|
||||
'callbacks' => [
|
||||
Event::ON_HAND_SHAKE => [Hyperf\WebSocketServer\Server::class, 'onHandShake'],
|
||||
Event::ON_MESSAGE => [...],
|
||||
Event::ON_CLOSE => [...],
|
||||
],
|
||||
]
|
||||
```
|
||||
|
||||
## 连接管理器
|
||||
|
||||
WebSocketConnectionManager:Redis HASH `ws:conn:{fd}` 存 user_id/server_id/connected_at。Redis SET `ws:user:{userId}` 存 `{serverId}:{fd}`(支持多连接)。addConnection、removeConnection、getUserConnections、getUserIdByFd、isOnline。
|
||||
|
||||
## WebSocket Controller
|
||||
|
||||
OnOpenInterface:从 query token 验证 JWT,无效则 close。addConnection。push connected 消息。OnMessageInterface:解析 type,ping→pong。OnCloseInterface:removeConnection。validateToken 返回 userId。
|
||||
|
||||
## 消息推送服务
|
||||
|
||||
WebSocketPushService:pushToUser(userId, type, data) 遍历 getUserConnections,Sender->push。pushToUsers 循环 pushToUser。broadcast 用 Redis publish 跨服务器。
|
||||
|
||||
## 前端 WebSocketClient
|
||||
|
||||
```typescript
|
||||
class WebSocketClient {
|
||||
constructor(url, token) {}
|
||||
connect() { this.ws = new WebSocket(`${url}?token=${token}`) }
|
||||
onmessage → emit(type, data)
|
||||
on(type, callback) → 返回 unsubscribe
|
||||
startHeartbeat() 30s ping
|
||||
onclose → scheduleReconnect 指数退避
|
||||
}
|
||||
```
