我的线路有问题

this.downloadURL = task.downloadURL()

使用AngularFireUploadTask,即使我导入它.

    import { Component, OnInit } from '@angular/core';
    import { AuthService } from '../../core/auth.service';
    import { AngularFireStorage, AngularFireStorageReference, AngularFireUploadTask } from 'angularfire2/storage';

    import { PostService } from '../post.service';
    import { Observable } from 'rxjs/Observable';



    @Component({
      selector: 'app-post-dashboard',
      templateUrl: './post-dashboard.component.html',
      styleUrls: ['./post-dashboard.component.css']
    })
    export class PostDashboardComponent implements OnInit {

      title: string;
      image: string = null;
      content: string;

      buttonText: string = "Create Post"

      uploadPercent: Observable<number>
      downloadURL: Observable<string>

      constructor(
        private auth: AuthService,
        private postService: PostService, 
        private storage: AngularFireStorage
      ) …
