登录后获取更新的XSRF令牌和Cookie：Angular 4

我有一个用户登录的应用程序，并向nodeJs后端发送一些请求 . 在我的应用程序中，我首先发送一个虚拟请求然后我得到一个_csrf和XSRF-token我将它们设置为 Headers 并发送登录详细信息 . 在登录响应中，我在cookie中获得了一个新的XSRF令牌 . 我需要将其添加到登录后我执行的帖子请求的 Headers 中 .

这是我的auth.service.ts

export class AuthService {

  authToken: any;
  user: any;

  constructor(private http: Http) { }

  registerUser(user) {
    let headers = new Headers();
    headers.append('Content-Type', 'application/json');
    return this.http.post('users/register', user, { headers: headers })
      .map(res => res.json());
  }

  authenticateUser(user) {
    let headers = new Headers();
    headers.append('Content-Type', 'application/json');
    return this.http.post('users/authenticate', user, { headers: headers })
      .map(res => res.json());
  }

  getProfile() {
    let headers = new Headers();
    this.loadToken();
    headers.append('Authorization', this.authToken);
    headers.append('Content-Type', 'application/json');
    return this.http.get('users/profile', { headers: headers })
      .map(res => res.json());
  }

  storeUserData(token, user) {
    localStorage.setItem('id_token', token);
    localStorage.setItem('user', JSON.stringify(user));
    this.authToken = token;
    this.user = user;
  }

  loadToken() {
    const token = localStorage.getItem('id_token');
    this.authToken = token;
  }

  loggedIn() {
    return tokenNotExpired('id_token');
  }

  logout() {
    this.authToken = null;
    this.user = null;
    localStorage.clear();
  }
}

我在登录后发送邮件请求的组件

export class DashboardComponent implements OnInit {

  form: FormGroup;
  authToken: any;

  public data:any[];
  constructor(private http:HttpClient) { }

  ngOnInit() {
  }

@ViewChild('f') tslForm: NgForm;
 onTslSubmit(f){
        var tslDetails={investingAmount:f.value.investingAmount,tradeStartAmount:f.value.tradeStartAmou$

this.add(tslDetails).subscribe(data =>{
        console.log(data,"response of send request");
    },error =>{
        console.log(error,"error");
  });
   this.tslForm.reset();
  }

 add(data: any){
  console.log(data,"before submit data");

  const token = localStorage.getItem('id_token');
  this.authToken = token;
   console.log("authToken: "+this.authToken);
 const httpOptions = {
   headers: new HttpHeaders({
   'Authorization':this.authToken,
   })
  }

  return this.http.post("http://0.0.0.0:3000/dummyurl", data, httpOptions).map((res: Response)=>$
 }

}

我需要发送一个帖子请求，其中包含已更新的XSRF令牌和cookie作为邮寄员的此帖子请求 .
