Question

我正在遵循该插件的官方文档，但无法使该插件正常工作。

app.module.ts

providers: [
    Network,
    BatteryStatus,
    StatusBar,
    SplashScreen,
    {provide: ErrorHandler, useClass: IonicErrorHandler}
  ]

home.ts

export class HomePage {
  level:any
  conn:any
  constructor(
    public navCtrl: NavController,
    private network:Network,
    public battery:BatteryStatus
  ) {}

  subscribeConnections(){
    let connectSubscription = this.network.onConnect().subscribe(() => {
      console.log('network connected!');
      this.conn = this.network.type;
      setTimeout(() => {
        if (this.network.type === 'wifi') {
          console.log('we got a wifi connection, woohoo!');
        }
      }, 3000);
    });

    const subscription = this.battery.onChange().subscribe(status => {
      console.log(status.level, status.isPlugged);
      this.level = status.level;
   });
  }

  ionViewDidLoad(){
    console.log('end');
    this.subscribeConnections();
  }

}

home.html

<ion-header>
  <ion-navbar>
    <ion-title>
      Ionic Blank
    </ion-title>
  </ion-navbar>
</ion-header>

<ion-content padding>
  The world is your oyster.

  </p>
  <p>level: {{level}}</p>
  <p>type: {{conn}}</p>
</ion-content>

batteryStatus和Network在模拟器中运行时是正常的，这是正常的，因为它需要cordova才能工作，但是networkinformation我在浏览器中找不到任何结果，错误在哪里？

我执行以下代码

未找到：

ionic cordova run browser

未找到：

ionic serve -l

发现：

ionic cordova run android -l

在浏览器中找不到ionic 4.2.1网络信息
