                }
            }
            });
    }
}

и мой код node.js:

 var express    = require('express');
app         = express();



var http = require('http');
var url = require('url');

  var PORT = (process.env.VCAP_APP_PORT || 8000);
 var HOST = (process.env.VCAP_APP_HOST || 'localhost');

 var queryData = null;

  http.createServer(function(request, response) {
  queryData = url.parse(request.url, true).query;
   console.log("Hai3");
  //respond to the client
   response.write("Got the GET request");
   response.end();
   }).listen(PORT, HOST);

Может ли кто-нибудь помочь мне в этом вопросе?
