Question

因为我正在使用ionic3并且我无法理解问题所在并且当我尝试创建登录功能时它显示“JSON输入的意外结束”并且在响应端数据也是空白的。

或者它是API连接问题???

我无法解决，有人知道请教我，我会很感激〜

login.ts

login(){
  this.authService.postData(this.userData,'login').then((result) => {
   this.responseData = result;
   if(this.responseData.userData){
   console.log(this.responseData);
   localStorage.setItem('userData', JSON.stringify(this.responseData)|| "[]");
   this.navCtrl.push(IframePage);
   }
   else{ swal({
    title: "Invalid Username or Password",
    text: "Please Try Again",
    icon: "warning",

  }); }
 }, (err) => {
   // Error log
 });

AUTH-service.ts

  this.http.post(apiUrl + type, JSON.stringify(credentials),{headers:headers})
    .subscribe(res => {
      resolve(res.json());
    }, (err) => {
      reject(err);
    });
});

auth.service.ts

import 'rxjs/add/operator/map';

     return this.http.post(apiUrl + type, JSON.stringify(credentials),{headers:headers}).map(res => res.json())

订阅登录功能

   this.navCtrl.push(IframePage);
   }
   else{ swal({
