401 Ionic 2中POST请求的未授权错误？

我有一个验证用户的问题。如果凭证（电子邮件和密码）出现问题，我会显示一条包含敬酒的错误消息。但从今天上午开始，我出现了401未经授权的错误，因此吐司不再显示错误消息。我不明白它来自哪里。401 Ionic 2中POST请求的未授权错误？

控制台的错误

POST UrlAPI 401 (Unauthorized) 
EXCEPTION: Response with status: 401 Unauthorized for URL: UrlAPI

这是我的POST请求

return this.http.post(link, data, options) 
    .map((res: Response) => res.json()) 
    .subscribe((response) => { 
      console.log("RESPONSE: ", response); 
      if (response.status === 'ok'){ 
       this.UserData.setSessionId(response.session_id); 
       console.log("SESS_ID SAVED", this.UserData.getSessionId()); 
       this.nav.setRoot(TabsPage); 
      } 
      else { 
       let toast = this.toastCtrl.create({ 
        message: response.errors, 
        duration: 3000, 
        position: 'top' 
       }); 
      toast.present(); 
      } 
     });

的问题是，当比2xx的状态码从服务器，或者从服务器返回的时间的角度HTTP服务引发错误。

这是通过将.MAP和.subscribe之间可观察到的捕获，或通过添加一个第二参数的订阅，这是一种错误处理程序处理。

溶液1

.map(...) 
.catch(/* handle error here */) 
.subscribe(...)

溶液2

.map(...) 
.subscribe( 
    (response) => { ... }, 
    (error) => { /*handle error here */ } 
)
