  <pre><code>var headers = new Headers();
          headers.append('Content-Type': 'application/json;charset=UTF-8');
  
          this.http.get(urgentPostURL + encodeURIComponent(this.urgentpost.comment))

            this.result = data;
            console.log('UrgentPost Result : ' + this.result.Success);
  
            if (this.result.Success == true) {
                console.log("SUCESSS");
            } else {
                console.log("FAILED");
            }
  
          },err =&gt; console.error(err),() =&gt; console.log('done'));

  <p>What I'm doing wrong here?</p>
  
  <h2>Edited</h2>
  
  <p>After updated to the following code I'm still getting 401:</p>
  
  <pre><code>var headers = new Headers();
          headers.append('Content-Type': 'application/json;charset=UTF-8');
          headers.append('Authorization', 'Basic ' + btoa("123" + ':' + "123"));
          this.http.get(urgentPostURL + encodeURIComponent(this.urgentpost.comment), { headers: headers })
          .map((res:Response) =&gt; res.json())
          .subscribe(data =&gt; {
