Question

当我尝试使用Google+登录我的Ionic2 / Angular2应用程序时，当我“离子运行android”（模拟器或在区域设备上）时，我一直收到“空引用”错误。但是当我使用“离子发球”时，我没有得到那个错误。

“null引用”似乎表示在我作为Android运行时尝试使用Firebase之前未运行AngularFireModule.initializeApp(firebaseConfig)。

问题：

@NgModule声明的“导入”部分何时运行 Cordova vs作为网络浏览器观看时？
我的猜测是正确的 AngularFireModule.initializeApp(firebaseConfig)未运行在科尔多瓦？如果是这样，我该如何最好地确认？

app.module.ts

import { NgModule } from '@angular/core';
import { IonicApp, IonicModule } from 'ionic-angular';
import { MyApp } from './app.component';

import { FormsModule } from '@angular/forms';

// Pages
import { ForgotPasswordPage } from '../pages/auth/forgot-password/forgot-password';
import { AuthPage } from '../pages/auth/home/home';
import { LoginEmailPage } from '../pages/auth/login-email/login-email';
import { AboutPage } from '../pages/about/about';
import { ContactPage } from '../pages/contact/contact';
import { SignUpPage } from '../pages/auth/sign-up/sign-up';
import { HomePage } from '../pages/home/home';
import { TermsOfServicePage } from '../pages/terms-of-service/terms-of-service';
import { TabsPage } from '../pages/tabs/tabs';

import { AngularFireModule } from 'angularfire2';

// Providers
import { DataProvider } from '../providers/data';
import { AuthProvider } from '../providers/auth';

export const firebaseConfig = {
  apiKey: '****',
  authDomain: '****.firebaseapp.com',
  databaseURL: 'https://****.firebaseio.com/',
  storageBucket: '****.appspot.com',
};

@NgModule({
  declarations: [
    MyApp,
    ForgotPasswordPage,
    AuthPage,
    LoginEmailPage,
    SignUpPage,
    AboutPage,
    ContactPage,
    TermsOfServicePage,
    HomePage,
    TabsPage
  ],
  imports: [
    AngularFireModule.initializeApp(firebaseConfig),
    IonicModule.forRoot(MyApp),
    FormsModule
  ],
  bootstrap: [IonicApp],
  entryComponents: [
    MyApp,
    ForgotPasswordPage,
    AuthPage,
    LoginEmailPage,
    SignUpPage,
    AboutPage,
    ContactPage,
    HomePage,
    TabsPage,
    TermsOfServicePage
  ],
  providers: [
    DataProvider,
    AuthProvider
  ]
})
export class AppModule {}

Google登录auth.ts的一部分

loginWithGooglePlus() {
  return Observable.create(observer => {
    if (this.platform.is('cordova')) {
      GooglePlus.login(['public_profile', 'email']).then(googlePlusData => {
        let provider = firebase.auth.GoogleAuthProvider.credential(googlePlusData.authResponse.accessToken);
        firebase.auth().signInWithCredential(provider).then(firebaseData => {
          // process user data
          observer.next();
        });
      }, error => {
        observer.error(error);
      });
    } else {
      this.af.auth.login({
        provider: AuthProviders.Google,
        method: AuthMethods.Popup
      }).then((googlePlusData) => {
        // process user data
        observer.next();
      }).catch((error) => {
        console.info("error", error);
        observer.error(error);
      });
    }
  });
}

错误（如Android Studio中所示，使用“离子生成安卓”文件）

这是在config.xml文件中

<plugin name="cordova-plugin-googleplus" spec="~5.1.1">
    <variable name="REVERSED_CLIENT_ID" value="com.****.****" />
</plugin>

Answer 1

你在这里使用的是什么：

<plugin name="cordova-plugin-googleplus" spec="~5.1.1">
    <variable name="REVERSED_CLIENT_ID" value="com.****.****" />
</plugin>

我遇到了完全相同的问题，并意识到当您在Google Developers Console中实际传递反向网络ID时，我正在传递我的包ID com.javebratt.packagename，所以它类似于：{{1} }

然后它开始工作了一半时间并打破另一半，所以我决定将webId传递给com.googleusercontent.apps.<uniqueIdHere>函数，它开始工作没有任何问题。
