我正在尝试从 Firebase 获取数据库。
我已经完成了这个tutorial。
运行ng serve
之后没有任何反应,我在控制台中出现此错误:
[2018-05-21T12:25:48.364Z] @ firebase / firestore:Firestore(5.0.3):无法访问Firestore后端。
environment.ts :
export const environment = {
production: false,
firebase: {
apiKey: "AIzaSyCip0O3rjU6AXHUKZg7Z26hpLZThTfStsA",
authDomain: "clientpanel-c4a89.firebaseapp.com",
databaseURL: "https://clientpanel-c4a89.firebaseio.com",
projectId: "clientpanel-c4a89",
storageBucket: "clientpanel-c4a89.appspot.com",
messagingSenderId: "894070096713"
}
};
app.module.ts :
import { BrowserModule } from '@angular/platform-browser';
import { NgModule } from '@angular/core';
// FIREBASE / ANGULARFIER2
import { environment } from '../environments/environment';
import { AngularFireModule } from 'angularfire2';
import { AngularFirestoreModule } from 'angularfire2/firestore';
import { AngularFireStorageModule } from 'angularfire2/storage';
import { AngularFireAuthModule } from 'angularfire2/auth';
// COMPONENTS
import { AppComponent } from './app.component';
@NgModule({
declarations: [
AppComponent
],
imports: [
BrowserModule,
AngularFireModule.initializeApp(environment.firebase),
AngularFirestoreModule,
AngularFireStorageModule,
AngularFireAuthModule
],
providers: [],
bootstrap: [AppComponent]
})
export class AppModule { }
app.component.ts :
import { Component } from '@angular/core';
import { AngularFirestore } from 'angularfire2/firestore';
import { Observable } from 'rxjs';
@Component({
selector: 'app-root',
templateUrl: 'app.component.html',
styleUrls: ['app.component.css']
})
export class AppComponent {
items: Observable<any[]>;
constructor(db: AngularFirestore) {
this.items = db.collection('/client').valueChanges();
}
}
app.component.html :
<h2>The list</h2>
<ul>
<li class="text" *ngFor="let item of items | async">
{{item.email}}
</li>
</ul>
最后,这是My Firebase
答案 0 :(得分:0)
您的屏幕截图显示您正在使用firebase实时数据库,但您的代码使用了firebase Cloud Firestore。
将AngularFirestore
更改为AngularFireDatabase
。
您的数据库的工作示例:https://stackblitz.com/edit/so002
-OR -
将您的数据移至Cloud Firestore
