Question

我如何检查 Ionic 4 中每个页面的互联网连接。如果出现网络错误，我需要将应用程序重定向到错误页面。

您可以尝试官方的 Ionic Network 插件(文档 here)。

来自文档的用法示例:

import { Network } from '@ionic-native/network/ngx'; //ngx

constructor(private network: Network) { }

...

// watch network for a disconnect
let disconnectSubscription = this.network.onDisconnect().subscribe(() => {
  console.log('network was disconnected :-(');
});

// stop disconnect watch
disconnectSubscription.unsubscribe();


// watch network for a connection
let connectSubscription = this.network.onConnect().subscribe(() => {
  console.log('network connected!');
  // We just got a connection but we need to wait briefly
   // before we determine the connection type. Might need to wait.
  // prior to doing any api requests as well.
  setTimeout(() => {
    if (this.network.type === 'wifi') {
      console.log('we got a wifi connection, woohoo!');
    }
  }, 3000);
});

// stop connect watch
connectSubscription.unsubscribe();
