等待Api的反應 - Angular js 2

Question

我想在cookie中放置一個標記唯一的問題，並且在獲取API的響應之前創建cookie，我該怎麼做才能等待作出迴應，然後創建cookie？

我的代碼

getlogin() 
{ 
this._symfonyservice.login(this.user,this.pass).subscribe(//call the post 
      data => this.results = data, // put the data returned from the server in our variable 
      error => console.log("Error HTTP Post Service"), // in case of failure show this message 
      () => console.log(this.results['token'])//run this code in all cases 
     ); 
if(this.results['token']!="") 
{ 
    let token = this.results['token']; 
    this.deleteCookie("Cookieteste"); 
    this.setCookie("Cookieteste",token, 1); 
} 
    } 

Answer 1

做到在data而不是() final function

getlogin() 
{ 
this._symfonyservice.login(this.user,this.pass).subscribe(//call the post 
data => { 
      this.results = data 
      if(this.results['token']!="") 
      { 
       let token = this.results['token']; 
       this.deleteCookie("Cookieteste"); 
       this.setCookie("Cookieteste",token, 1); 
      }  
     }, // put the data returned from the server in our variable 
       error => console.log("Error HTTP Post Service"), // in case of failure show this message 
       () => console.log('completed')//run this code in all cases 
    );
