this is my header response

The problem is that you map your response to its json content. Headers can be reached from the response itself. So you need to remove the map operator:

this.http.post(this.loginUrl,        JSON.stringify({ "username": value.username, "password": value.password }),        { headers: headers })         /*.map((res: Response) =>  // <--------------                 res.json())*/        .subscribe((res) => {          var payload = res.json();          var headers = res.headers;           var setCookieHeader = headers.get('Set-Cookie')          (...)        }); 

Be careful with CORS with accessing the response headers. See this question:
