@ firebase/database:用户回调抛出了异常.TypeError:无法读取未定义的属性"myID"

Question

一旦我将我的应用程序构建到生产到Firebase托管中,我就会遇到一些用户的错误:

@ firebase/database:FIREBASE警告:用户回调抛出了异常.TypeError:无法读取未定义的属性"myID"

在我的代码中,在任何地方都没有变量"myID" .一切都可以很好地用于开发,但是一旦它被构建并在生产中,错误就会出现在某些用户身上.

这是我的packages.json版本:

编辑 此问题仅在我使用以下内容将其部署到firebase后运行应用程序时发生:

ng build --prod
firebase deploy

当我点击1:789549抛出的异常时:

我可以从Chrome浏览器中将此代码看到源控制台:

(function(){var t={};return 
 t.id=this.myID,t.pw=this.myPW,t.ser=this.currentSerial,t}())

这是我的auth.service.ts.当我仅在生产中调用函数Login()时抛出异常.

import { UserService } from './user.service';
import { AppUser } from '../models/app-user';
import { AngularFireAuth } from 'angularfire2/auth';
import { Injectable } from '@angular/core';
import * as firebase from 'firebase';
import { Observable } from 'rxjs/Observable';
import { ActivatedRoute } from '@angular/router';
import 'rxjs/add/operator/switchMap';
import 'rxjs/add/observable/of';

@Injectable()
export class AuthService {
user$: Observable<firebase.User>;

constructor(
   private afAuth: AngularFireAuth, 
   private route: ActivatedRoute,
   private userService: UserService) {
   this.user$ = afAuth.authState;
 }

login(){
let returnUrl = this.route.snapshot.queryParamMap.get('returnUrl') || '/';
localStorage.setItem('returnUrl', returnUrl);

this.afAuth.auth.signInWithRedirect(new firebase.auth.GoogleAuthProvider());
}

logout(){
    this.afAuth.auth.signOut();
}

get appUser$(): Observable<AppUser>{
  return this.user$
  .switchMap(user => {
    if (user) return this.userService.get(user.uid).valueChanges();
    return Observable.of(null);
});
}
}

Answer 1

这是一个解决方法：

如果我使用以下方法修改我的 login() 方法：

this.afAuth.auth.signInWithPopup(new firebase.auth.GoogleAuthProvider());

代替 ：

 this.afAuth.auth.signInWithRedirect(new firebase.auth.GoogleAuthProvider());

我现在可以连接到生产环境了。这个问题的根源似乎在于重定向功能。
