我正在创建一个简单的示例auth应用程序,Ionic 2和angularfire 2作为后端,当我尝试创建新用户时,它说:

EXCEPTION:错误:未捕获(在承诺中):错误:未为此Firebase启用指定的身份验证提供程序.

但是我已经在firebase控制台中启用了firebase身份验证:

app.ts

import {App, Platform} from 'ionic-angular';
import {StatusBar} from 'ionic-native';
import {HomePage} from './pages/home/home';
import { FIREBASE_PROVIDERS, defaultFirebase, firebaseAuthConfig, AuthProviders, AuthMethods } from 'angularfire2';

@App({
  template: '<ion-nav [root]="rootPage"></ion-nav>',
  providers: [
    FIREBASE_PROVIDERS,
    defaultFirebase('https://samplequizapp-50eb5.firebaseio.com'),
    firebaseAuthConfig({
      provider: AuthProviders.Password,
      method: AuthMethods.Password
    })
  ],
  config: {} // http://ionicframework.com/docs/v2/api/config/Config/
})
export class MyApp {
  rootPage: any = HomePage;

  constructor(platform: Platform) {
    platform.ready().then(() => {
      // Okay, so the platform is ready and our plugins are available.
      // Here you can do …

我有一个情况,我必须把嵌套ng-repeat,当我试图得到的$id第一个ng-repeat我没有任何问题,但当我试图获得$id第二个ng-repeat(下图中标记为红色)我got undefined.

我的Firebase结构如下

这是items对象

HTML代码和控制器在这里

angular
  .module('starter')
  .controller('feedController', function($scope, $firebaseRef, $firebaseArray) {

    $scope.allRequests = $firebaseArray($firebaseRef.requests);

    $scope.allRequests.$loaded(function() {
      console.log(arguments);
    })

  })

<script src="https://ajax.googleapis.com/ajax/libs/angularjs/1.2.23/angular.min.js"></script>
<span ng-repeat="items in allRequests">   
    <!-- this works fine -->
      {{items.$id}}
      
      <div ng-repeat="item in items">
        
       <!-- getting undefined here... -->
      {{item.$id}}
      
    </div>
 </span>

我需要$id第二ng-repeat,任何帮助将不胜感激.
