how to read content-disposition headers from server response angular 2

With new Angular Http, one can try the following in the Service code.

  downloadLink(): Observable<HttpResponse<Blob>> {
    return this.http.get<Blob>(this.someURL, {
      observe: 'response',
      responseType: 'blob' as 'json'
    });
  }

And use the above as

 this.someService
  .downloadLink()
  .subscribe(
    (resp: HttpResponse<Blob>) => {
      console.log(resp.headers.get('content-disposition'));
      data = resp.body
    });

Also, on the server side, one needs to set the following header in response. 'Access-Control-Expose-Headers': 'Content-Disposition'

Like in Java Spring Boot one can do the same using

    final HttpHeaders headers = new HttpHeaders();
    headers.add(HttpHeaders.CONTENT_DISPOSITION, "attachment; filename=1.xlsx");
    headers.add(HttpHeaders.ACCESS_CONTROL_EXPOSE_HEADERS, HttpHeaders.CONTENT_DISPOSITION);
