Angular 8 Websocket用户使用rxjs键入事件

npm install rxjs

import { Component, OnInit } from '@angular/core';
import { WebSocketSubject } from 'rxjs/webSocket';
import { filter, map } from 'rxjs/operators';

@Component({
  selector: 'app-websocket-example',
  templateUrl: './websocket-example.component.html',
  styleUrls: ['./websocket-example.component.css']
})
export class WebsocketExampleComponent implements OnInit {
  private socket$: WebSocketSubject<any>;

  ngOnInit() {
    // 创建Websocket连接
    this.socket$ = new WebSocketSubject('ws://example.com/socket');

    // 使用rxjs操作符处理接收到的数据
    this.socket$.pipe(
      filter((data: any) => data.type === 'event'),
      map((data: any) => data.payload)
    ).subscribe((payload: any) => {
      // 处理接收到的数据
      console.log(payload);
    });
  }

  // 发送数据到Websocket服务器
  send(data: any) {
    this.socket$.next(data);
  }
}
