我想问个问题，我如何在angular使用websocket的同时使用路由代理

这是我service的代码

import { Injectable } from '@angular/core';

@Injectable({
  providedIn: 'root'
})
export class WebsocketService {

  public ws: WebSocket;//定义websocket

  connectWs(websocket: string) {
    if (this.ws != null) { this.ws.close() };
    this.ws = new WebSocket(websocket);
    let that  = this;
    this.ws.onopen = function (event) {
            //socket 开启后执行，可以向后端传递信息
            setTimeout(()=> {
              that.ws.send('sonmething');
            },10000);
    }
    this.ws.onmessage = function (event) {
            //socket 获取后端传递到前端的信息
            //接收到消息会打开
            let indexButton: HTMLElement = document.querySelector('.open') as HTMLElement;
            indexButton.click();
    }
    this.ws.onerror = function (event) {
            //socket error信息


    }
    this.ws.onclose = function (event) {
            //socket 关闭后执行

    }
  }
}
