Question

我是angular2框架的新手。我使用angular2-websocket插件在我的项目中使用websockets。我的方案是，如果一旦套接字连接关闭，它就不会在服务器端打开套接字时重新连接。我怎么能用angular2-websocket做到这一点？如何在打开套接字时重新连接到套接字？

这是我的app.component.ts代码段

import { Component, OnInit } from '@angular/core';
import { $WebSocket, WebSocketSendMode } from 'angular2-websocket/angular2-websocket';
import { WebsocketService } from '../../../services/websocket.service';

@Component({
  selector: 'app-init',
  templateUrl: './app.component.html',
  styleUrls: ['./app.component.scss']
})
export class AppComponent implements OnInit {

  constructor(private websocket:WebsocketService) { }
  ngOnInit() {
      this.fnGraphInit("ws://10.1.40.117:5555");
  }


fnGraphInit(url){

let ws = new $WebSocket(url);
    ws.getDataStream().subscribe(
      (msg) => { 
        console.log(msg.data);

      (msg) => {
        console.log("error", msg);

      },
      () => {
        console.log("complete");

      }
    );
}

}
}

请帮我解决这个问题。

尝试使用WebSocketConfig：

const webSocketConfig = { reconnectIfNotNormalClose: true } as WebSocketConfig;

this.ws                  = new $WebSocket(url, null, webSocketConfig);

如何在Angular2应用程序中使用angular2-websocket关闭websocket连接？
