Angular firebase upload images












1















I am a beginner working with Angular 5 and firebase.
As practice I decided to create a blog.
My problem is that I can not upload my images in firestore. When I upload to Cloud storage and try to retrieve the download link, it does not register in firestore.



Take a look at my code and give me suggestions.






import { Component, OnInit } from '@angular/core';
import { AuthService } from 'src/app/shared/services/auth.service';
import { finalize } from 'rxjs/operators';
import { Observable } from 'rxjs';
import { AngularFireStorage } from '@angular/fire/storage';
import { PostsService } from 'src/app/shared/services/posts.service';
import { ToastrService } from 'ngx-toastr';
import { Router } from '@angular/router';



@Component({
selector: 'app-posts',
templateUrl: './posts.component.html',
styleUrls: ['./posts.component.scss']
})
export class PostsComponent implements OnInit {

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

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

constructor(private auth: AuthService,
private toast: ToastrService,
private postService: PostsService,
private store: AngularFireStorage,
private router: Router) { }

ngOnInit() {
}

createPost() {
// tslint:disable-next-line:prefer-const
let data = {
content: this.content,
image: this.image,
description: this.description,
publication: new Date(),
title: this.title
};
this.router.navigate(['/admin']);
this.postService.create(data);
this.title = '';
this.description = '';
this.content = '';
this.toast.success('Votre article a été publié');
}

uploadImage(event) {
// tslint:disable-next-line:prefer-const
let file = event.target.files[0];
// tslint:disable-next-line:prefer-const
let path = `posts/${file.name}`;
if (file.type.split('/')[0] !== 'image') {
return alert('Erreur, ce fichier n'est pas une image');
} else {
// tslint:disable-next-line:prefer-const
let ref = this.store.ref(path);
// tslint:disable-next-line:prefer-const
let task = this.store.upload(path, file);
this.uploadPercent = task.percentageChanges();
console.log('Image chargée avec succès');
task.snapshotChanges().pipe(
finalize(() => {
this.downloadURL = ref.getDownloadURL();
this.downloadURL.subscribe(url => {
console.log(url);
});
}
)
).subscribe();
}
}

    Thank you for your interest. By the way there is no mistake just that in Cloud storage, the upload is done perfectly but when recovering the download link to save it in firestore, in the console firebase it displays something like C: fakepath 72e39b1d336__CI_W28_S4_Jumia-Trust-2.jpg instead of the download link so that it can be displayed by the user.

Thank you for your interest. By the way there is no mistake just that in Cloud storage, the upload is done perfectly but when recovering the download link to save it in firestore, in the console firebase it displays something like C: fakepath 72e39b1d336__CI_W28_S4_Jumia-Trust-2.jpg instead of the download link so that it can be displayed by the user.
