从外部链接返回后，Ionic inappbrowser 无法正常工作

Question

我有一个带有 ios、android 和浏览器的离子项目。 The problem is in IOS and Android: from tab1.page.html, after opening a login page (which in an external server) in the iOS browser without any problem, that external page has a link back to the ionic project(to map. component.html) 可以正常打开，但是页面中应该再次打开浏览器的按钮将不起作用，没有错误，没有什么，只是没有任何动作。

如果我直接从离子项目内部打开 map.component.html 按钮工作正常并且浏览器打开。 只有当按钮什么都不做时，我才从外部页面返回。

任何帮助将不胜感激，这几天我的头撞墙了......

tab1.page.html

<div>
<a href="#" routerLink="/login" routerDirection="root"><ion-ripple-effect></ion-ripple-effect><img src="../../assets/images/top-btn-reserve.png" class="drop-shadow" alt="login"></a>
</div>

登录页面.ts

private  loginUrl = 'https://test.blabla.reservation/index';
    constructor(
        private inAppBrowser: InAppBrowser
    ) {
    }

    ngOnInit() {
        const browser = this.inAppBrowser.create(this.loginUrl, '_self', {location: 'no', zoom: 'no', toolbar: 'no'});
    }

应用程序路由模块

{ path: 'guidance', loadChildren: './guidance/tab2.module#Tab2PageModule',pathMatch: 'full'},

map.component.ts

openMapApp() {
        console.log("In openMAPPPP");
        const browser = this.inAppBrowser.create('https://www.google.com', '_system', {location: 'yes', zoom: 'no', toolbar: 'no'});
}

map.component.html

<ion-button  id="navigation_icon" class="navigation_icon" shape="round" size="default" color="light" (click)="openMapApp()">GoogleMapsで見る</ion-button>

在外部浏览器中打开后回调 url。

例如 this.iabRef = this.iab.create("https://stackoverflow.com/", "_blank", "beforeload=yes,location=no");

this.iab.create(event.url, "_system"); this.iabRef._loadAfterBeforeload(event.url);
