javascript - How to extract data from url fetch response -

i implemented fetch method using google script , returns me following log:

[16-06-10 14:06:03:942 eest] {   "accesstoken": "data",   "userid": 3096,   "created": "2016-06-10t05:06:03.799-06:00" } 

does know how can extract value accesstoken ?

here gs code:

  var url = "https://example.com"   var payload = {     'username' : "user",     'password' : "pass",   }   var options = {     'method' : 'post',     'payload': json.stringify(payload),   };   var urlresponse = urlfetchapp.fetch(url, options);   logger.log(urlresponse); //this returns me log shown above 

basically want add "data" value accesstoken variable getdata.

i think if variable urlresponse object return string value. should try that:

var data = json.parse(urlresponse.getcontenttext()); logger.log(data.accesstoken);
