离子网络类型= null

Question

iam dev One App在离子V2 TS中。我的network.type等于null。有什么问题？

import { Network } from '@ionic-native/network';
@Component({
  selector: 'page-home',
  templateUrl: 'home.html',
  providers: [ProviderAccessApi]
})
export class HomePage {
  user : string;
  pass:string;
  constructor(public navCtrl: NavController, public providerAPI:ProviderAccessApi, private platform: Platform, public alertCtrl : AlertController, public network : Network) {
      console.log('HomePage carragada com sucesso')
      alert(network.type);
  }

首先，请注意，您应该将与网络相关的代码放置在this.platform.ready().then(() => {...});的内部，以在平台准备就绪时执行它。

import { Network } from '@ionic-native/network';
@Component({
  selector: 'page-home',
  templateUrl: 'home.html',
  providers: [ProviderAccessApi]
})
export class HomePage {
  user : string;
  pass:string;
  constructor(public navCtrl: NavController, 
              public providerAPI: ProviderAccessApi, 
              private platform: Platform, 
              public alertCtrl : AlertController, 
              public network : Network) {
      console.log('HomePage carragada com sucesso');
      this.platform.ready().then(() => {
          // Now all cordova plugins are ready!
          alert(network.type);
      });
  }
}
