i make following call facebook id

var request = new oauth2request ("get", new uri ("https://graph.facebook.com/me"), null, args.account);                 request.getresponseasync ().continuewith (t => {                     var obj = jsonvalue.parse (t.result.getresponsetext ());                     var id = obj ["id"];                 });
