角4饼干问题

Question

我在响应标头中收到了Cookie，但我无法将它们存储在浏览器Cookie中，因为浏览器没有自动保存它。有人可以帮我这个吗？

注意：我已尝试withCredentials:true和crossDomain:true以及所有其他可用选项。

this.headers.set("Content-Type","application/x-www-form-urlencoded; charset=UTF-8");
  this.headers.set("dataType","json");
  this.headers.set('crossDomain','true');
  this.headers.set('Access-Control-Allow-Origin','*');
  this.headers.set("Access-Control-Allow-Credentials","true");
  this.headers.set("Access-Control-Allow-Headers","*");

 let options = new RequestOptions({headers:this.headers,withCredentials: true,params:data});

  this.http.post(this.API_URL+this.BASE_URL+'auth/login/',options).subscribe(data => {
    console.log(document.cookie);
      this.router.navigate(['/dashboard']);
  }, error => {
    var display=error.json();
    this.error='* '+display.message;
  });
