# 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 } ```
