在混合应用程序(Angular和Apache Cordova)中保持套接字在后台运行

import { Component, OnInit } from '@angular/core';
import { Socket } from 'socket.io-client';

@Component({
  selector: 'app-root',
  templateUrl: './app.component.html',
  styleUrls: ['./app.component.css']
})
export class AppComponent implements OnInit {
  private socket: Socket;

  ngOnInit() {
    document.addEventListener('deviceready', () => {
      cordova.plugins.backgroundMode.enable();

      this.socket = io('http://your-socket-server.com');

      this.socket.on('connect', () => {
        console.log('Connected to socket server');
      });

      this.socket.on('message', (data) => {
        console.log('Received message:', data);
      });

      // Handle background mode events
      document.addEventListener('pause', () => {
        console.log('App is in background');
      }, false);

      document.addEventListener('resume', () => {
        console.log('App is in foreground');
      }, false);
    });
  }
}
