  {reportProgress: true});

this.http.request(request).subscribe(value => {
  if (value.type === HttpEventType.DownloadProgress) {
    const newValue = value as HttpProgressEvent;
    const percent = Math.round(100 * newValue.loaded / newValue.total);
    console.log(percent);
  } else if (value.type === HttpEventType.Response) {
    console.log('File was completely downloaded!');
  }
