import { Component } from '@angular/core';
declare var firebase : any;

@Component({
  template: '<img [src]="image">'

  constructor() {
    const storageRef = firebase.storage().ref().child('images/image.png');
    storageRef.getDownloadURL().then(url => this.image = url);
  }
}

我在浏览器控制台中收到以下错误:

EXCEPTION: Error: Uncaught (in promise): EXCEPTION: Error in ./bstorageComponent class FBStorageComponent_Host - inline template:0:0
ORIGINAL EXCEPTION: Error: No Firebase App '[DEFAULT]' has been created - call Firebase App.initializeApp().
ORIGINAL STACKTRACE:
Error: No Firebase App '[DEFAULT]' …

如何使用角火2从Fire基地存储中获取图像2.非常感谢!

constructor(public af: AngularFire) {
