无法使用Angular2进行重定向请求

Question

我正在尝试登录后端服务，该服务在使用表单数据登录后将其重定向到不同的URL。当我尝试使用REST客户端（Postman）登录时，请求是成功的，但是当我尝试使用Angular 2 Ionic尝试相同时。我不确定为什么它不起作用。

Postman的成功请求

使用离子2使用Angular 2

代码

 public login() {
    let headers = new Headers({ 'Content-Type': 'multipart/form-data' });
    let options = new RequestOptions({ headers: headers });

    var input = new FormData();
    input.append('email', '[e-mail]');
    input.append('password', 'test123456');
     this.http.post('http://127.0.0.1:9000/auth/login', input, headers)
     .map((res:Response) => {
       var location = res.headers.get('Location');
       console.log(res.headers.get('Location'));
      }).subscribe(data => {
       console.log(data);
     });
    }

响应

Answer 1

您是否尝试在标题后添加withCredentials: true？

这样：

return this.http. post(
   'http://127.0.0.1:9000/auth/login',
   {
     headers: this.headers,
     withCredentials: true
   },
)
