Angular 5 net :: ERR_UNKNOWN_URL_SCHEME用于来自快递服务器的图像

Question

我在显示来自我的node.js（快速服务器）localhost：3000 / assets / images / uploads的图像时遇到了一些麻烦。当我在浏览器中输入此URL时，此方法工作正常，浏览器显示图像，但是当我将其分配给Angular 5应用中的变量并使用绑定到时，我得到

无法加载资源：net :: ERR_UNKNOWN_URL_SCHEME。

我附上下面的代码。请检查一下。

export class ProfileComponent implements OnInit {

  user: any;
  url: "";
  path: SafeUrl;
  public uploader:FileUploader = new FileUploader({url: URL, itemAlias: 'photo'});
  
  constructor(private authService: AuthServiceService,
              private userService: UsersService,
              private http: Http,
              private el: ElementRef,
              private _DomSanitizationService: DomSanitizer) {

      
    
    
    
   }


  ngOnInit() {
    this.user = this.authService.user;
    console.log(this.user);
    this.path = this._DomSanitizationService.bypassSecurityTrustUrl(this.user.img);

<input type="file" name="photo" ng2FileSelect [uploader]="uploader" />
<!-- button to trigger the file upload when submitted -->
<button type="button" class="btn btn-success btn-s" (click)="uploader.uploadAll()" [disabled]="!uploader.getNotUploadedItems().length">
      Upload with ng-2 file uploader
</button>

解！

对于有此问题的任何人，请确保在image source属性中提供的地址后面加上“ http：//”，因为在我的情况下，我没有附加它。这为我解决了问题，现在它就像一个魅力！

你url必须有点像这样的： “ HTTP：//本地主机：3000 /资产/图像/上传/ c91a3649fc432040e54b9179a72539ad1530343409773.png ”

令人困惑的部分实际上是，当您在浏览器的url中编写它（没有http：//）时，它会自动附加它而不通知我们，但是Angular并非如此，您必须显式编写它。编码愉快。我希望这对某人有帮助，因为我花了14个小时才弄清楚。
