Answer 1

你必须异步调用你的PHP后台通过AJAX：

return $http.get("https://yourbackend.com/api/your_call") 
    .then(function(response){ 
     /* Here you can process the backend response */ 
    });

当我打电话PHP服务器，服务器使用JSON数据对象回应我，我需要导航如果状态为真，则转到页面。

login(){ 

let headers = new Headers(); 
    headers.append('Content-Type', 'application/json'); 

let alert = this.alert.create({ 
      title: 'Warning', 
      subTitle: 'Wrong Username or Password! Please Try Again !', 
      buttons: ['OK'] 
      }); 
let loader = this.loading.create({ 
      content: "Checking ! Please wait...", 
      duration: 1000 
     }); 

let email = this.data.email; 

let password = this.data.password; 
let data = JSON.stringify({email, password}); 
let link = "http://"link""; 


    this.http.post(link, data, {headers: headers}) 
     .subscribe(res => { 
     this.navCtrl.setRoot(Page1); 
     loader.present(); 
     console.log(res.json()); 
     }, (err) => { 
     console.log(err); 
     alert.present(); 
     }); 

}}
