在Postman中调用API,直接返回一张图片,这种API在Angular8中如何调用？

Question

如题，使用Angular如下方法调用，报错如下：

getThumbnail(viewId: string):Observable<any> {
  const headersSite = new HttpHeaders().append('X-Tableau-Auth', storage.getItem('tokenQ'));
  const hdrSite = { headers: headersSite };
  return this.http.get(this.uri_tableau + 'api/3.9/sites/' + storage.getItem('siteIdCustomer') + '/views/' + viewId + '/image', hdrSite)
  .pipe(
    tap(v => console.log(v)),
    map(
    (viewsRes) => {
      return viewsRes;
    }
    ))

}

this.dataServe.getThumbnail(this.viewUrl).subscribe(v => console.log(v))  // 无法打印

这种情况，如何处理？

直接<img [src]="**"/>
