## 1. EventsGateway 实现
```typescript
@WebSocketGateway({ cors: { origin: "*" } })
export class EventsGateway {
@WebSocketServer()
server: Server;
@SubscribeMessage("joinRoom")
handleJoinRoom(@MessageBody() room: string, @ConnectedSocket() client: Socket) {
client.join(room);
this.server.to(room).emit("userJoined", { id: client.id });
}
}
