The server responses with plain text and angular try to parse json. How do i turn of this behaviour in one component?

get(mrn: string): Observable<string> {
    let url: string;
    url = this.Url;
    url = url + '?mrn=' + mrn;
    return this.http.get<string>(url);
  }


download(testobject: Testobject): void {
    this.httpService.get(testobject.mrn)
      .subscribe(ccresult => {
        console.log('ccresult ist: ' + ccresult);
      });
  }

You can get HttpResponse object like this:

this.http.get<any>(url, { observe: 'response' }).map((res): HttpResponse) => ...);
