Ionic 3 Firebase Google Auth重定向到本地主机而不是应用程序

Question

我在Ionic 3项目中使用AngularFire2。我已经实现了Facebook和Google Login，它们以前都可以运行，但是以某种方式停止了运行（也许是因为Firebase SDK或Google发生了变化？）。

我现在面临的问题是，一旦用户通过带有重定向的google登录，他就可以登录，但无法在我的应用中重新获得重定向。相反，谷歌只是在重定向上显示此页面：

这是用于登录的代码：

private oauthSignIn(provider: AuthProv) {
      if (!(<any>window).cordova) {
        return this.afAuth.auth.signInWithPopup(provider).then((user) => {
          this.user = user.user;
        });
      } else {
        return this.afAuth.auth.signInWithRedirect(provider)
          .then(() => {
            return this.afAuth.auth.getRedirectResult().then(result => {
              this.user = result.user;
            });
          });
      }
    }

此代码来自AngularFire2文档本身，因此我找不到任何错误。

这是我的package.json：

}，

我已经尝试过this Solution并添加：

<preference name="CordovaWebViewEngine" value="CDVUIWebViewEngine" />
<allow-navigation href="http://*" />

到我的config.xml也没有任何改变。

我也试图降级

"cordova-plugin-ionic-webview": "4.1.1",

也没有用。

我的Google WebClient拥有正确的ClientID，Secred和重定向URL，就像在Firebase控制台中一样。

那我该如何解决这个问题？
