ありがとうとなりまし

var headers = new Headers(); 
headers.append('Accept', 'application/json'); 
headers.append('Content-Type', 'application/json'); 
//headers.append('Authorization' , 'Basic '+ btoa(tok)); 
let options = new RequestOptions({ headers: headers }); 

let postParams = { 
    username: this.uyelik['username'], 
    email:this.uyelik['email'], 
    password:this.uyelik['password'] 
} 

this.http.post("https://deneme.com/api/v1.0/users/", postParams, options) 
    .subscribe(data => { 
    console.log(data['_body']); 
    this.veri = data['_body']; 
    this.veri = JSON.parse(this.veri); 
    console.log(this.veri['token']); 
    }, error => { 
    console.log(error);// Error getting the data 
    });

this-

var a = '{\"msg_ok\": \"Uye olusturuldu\", \"user_id\": 181, \"token\": \"8650bfe987a3d619445f3d4905e1ae863e4be85f\"}'; 
 
a.replace(/\//g, ""); 
 
var token = JSON.parse(a).token; 
 
console.log(token)
