是否可以从我的ionic2应用程序重定向到外部应用程序？

ionic cordova plugin add cordova-plugin-inappbrowser
npm install @ionic-native/in-app-browser

import { InAppBrowser } from '@ionic-native/in-app-browser/ngx';

constructor(private iab: InAppBrowser) { }

const url = 'twitter://user?screen_name=ionicframework';
const browser = this.iab.create(url);

const url = 'twitter://user?screen_name=ionicframework';
const fallbackUrl = 'https://twitter.com/ionicframework';
const browser = this.iab.create(url);

browser.on('loadstart').subscribe(event => {
  if (event.url === url) {
    // External app opened successfully
    browser.close();
  } else if (event.url === fallbackUrl) {
    // External app not available, open fallback URL in browser
    browser.close();
    window.open(fallbackUrl, '_system');
  }
});
