angular - 等待 Api 的响应 - Angular js 2

Question

我想在 cookie 中放入一个 token ，这是唯一的问题，而且 cookie 是在获得 API 响应之前创建的，我如何才能等待响应然后创建 cookie？

我的代码

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);
}
   }

在 data 而不是 () final function 中执行

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
     );
