javascript - Angular 2 - 异常 : Error: unsafe value used in a resource URL context

Question

我收到以下错误:

Angular 2 - EXCEPTION: Error: unsafe value used in a resource URL context

这可能与启动时没有立即显示媒体项有关吗？还是与 URL 不安全有关？我正在尝试对其进行 sanitizer 。

export class HomeComponent {

  sanitizer: DomSanitizationService;
  errorMessage: string;
  activeMedia: MediaItem = new MediaItem(0, '', '', '', '', '', '');

  constructor(
    private mediaStorage: MediaStorageService, 
    private harvesterService: HarvesterService, 
    sanitizer: DomSanitizationService) {

    this.sanitizer = sanitizer;
    // Initial call - 
    harvesterService.getMediaItems(10, 'type', 'category');
    let subscription = harvesterService.initialMediaHarvestedEvent.subscribe(() => {
      this.activeMedia = mediaStorage.mediaList[0];
      let newURL = this.activeMedia.URL + '?rel=0&autoplay=1';
      newURL = newURL.replace('watch?v=', 'v/');
      this.activeMedia.URL = newURL; //sanitizer.bypassSecurityTrustUrl(newURL);
      console.log(newURL);
    });
  }

  cleanURL(oldURL: string): SafeResourceUrl {
    return this.sanitizer.bypassSecurityTrustUrl(oldURL);
  }
}

模板代码为:

<div class="row" >
    <iframe 
      id="video"  
      class="video" 
      src="{{ cleanURL(activeMedia.URL) }}" 
      frameborder="0" 
      allowfullscreen>
    </iframe>
</div>

Answer 1

更新:更改后

 src="{{cleanURL(activeMedia.URL)}}"

到:

 [src]="cleanURL(activeMedia.URL)"

我得到:原始异常:错误:需要一个安全的 ResourceURL，得到一个 URL

通过将 cleanURL 方法中的代码更改为:

 return this.sanitizer.bypassSecurityTrustResourceUrl(oldURL);

代替:

 return this.sanitizer.bypassSecurityTrustUrl(oldURL);
