singIn() {
    var headers = new Headers();
    headers.append("Accept", 'application/json');
    headers.append('Content-Type', 'application/json' );
    const requestOptions = new RequestOptions({ headers: headers });

    let postData = {
          "Email": this.username,
          "Password": this.password,
    }

    this.http.post("http://mydomainname/api/user", JSON.stringify(postData))
      .subscribe(data => {
        console.log(data.status);
       }, error => {
