Question

使用Angular 2 CLI，我有以下代码：

joinSubmit(){
    var self = this;
    firebase.auth().createUserWithEmailAndPassword(
        'test@test.com', 
        'testpassword'
        )
        .then(function(response){
            var userdetail = {};
            userdetail['/users/'+response.uid] = {
                username: 'test',
                useremail: 'test@test.com'
            };
            firebase.database().ref().update(userdetail);
        });
        this.router.navigate(['profile']);
}

不幸的是，当我运行它时，我收到No Firebase App [DEFAULT] has been created - call Firebase App.initializeApp()错误。

我的 app.module 看起来如此（显然填写了API密钥）：

import * as firebase from 'firebase';
import { BrowserModule } from '@angular/platform-browser';
import { NgModule } from '@angular/core';
import { FormsModule, ReactiveFormsModule } from '@angular/forms';
import { HttpModule } from '@angular/http';
import { AngularFireModule } from 'angularfire2';

import { AppComponent } from './app.component';
import { HomeComponent } from './home/home.component';
import { J2InvestRoutingModule } from './app-routing.module';
import { NavigationComponent } from './navigation/navigation.component';
import { JoinComponent } from './join/join.component';
import { SignComponent } from './sign/sign.component';
import { ProfileComponent } from './profile/profile.component';


  export const firebaseConfig = {
    apiKey: "",
    authDomain: "",
    databaseURL: "",
    storageBucket: "",
    messagingSenderId: ""
  };

@NgModule({
  declarations: [
    AppComponent,
    HomeComponent,
    NavigationComponent,
    JoinComponent,
    SignComponent,
    ProfileComponent
  ],
  imports: [
    BrowserModule,
    FormsModule,
    HttpModule,
    J2InvestRoutingModule,
    ReactiveFormsModule,
    AngularFireModule.initializeApp(firebaseConfig)
  ],
  providers: [],
  bootstrap: [AppComponent]
})
export class AppModule { }

同时我的 package.json 如下所示：

{
  "name": "j2-invest",
  "version": "0.0.0",
  "license": "MIT",
  "angular-cli": {},
  "scripts": {
    "start": "ng serve",

    "ts-node": "1.2.1",
    "tslint": "3.13.0",
    "typescript": "2.0.2"
  }
}

不知道如何解决此错误。请指教。感谢。

更新因此docs有一个脚本可用于初始化Firebase应用。

  // Intialize the "[DEFAULT]" App
  var mainApp = firebase.initializeApp({
    // ...
  });

如何将此功能合并到我的Firebase功能中？比方说，如果我有以下代码：

runner(){
    var mainApp = firebase.initializeApp({});
    firebase.auth().createUserWithEmailAndPassword('chase', 'myface');    
}

更新

所以来发现我的app.module初始化我的Firebase设置似乎存在某种问题。由于具有这样的功能可以解决问题：

    rest(){

    const firebaseConfig = {
    apiKey: "",
    authDomain: "",
    databaseURL: "",
    storageBucket: "",
    messagingSenderId: ""
};

    firebase.initializeApp();
        firebase.auth().createUserWithEmailAndPassword('chevy@chase.com', 'hispassword'); 
    }

虽然这有效，但每次拨打电话时都必须输入firebase.initializeApp()似乎并不理想。

Answer 1

我认为这会对你有所帮助。在主要组件中初始化应用程序。

AngularFireModule.initializeApp({
  apiKey: "*******************",
  authDomain: "**********.firebaseapp.com",
  databaseURL: "https://*********.firebaseio.com",
  storageBucket: ""
})

检查以下plunker

在Angular 2中没有创建Firebase应用程序'[DEFAULT]'
