                }
            }
            });
    }
}

and my node.js code is:

 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);

Can anyone help me in this issue?

Answer 1

In your Node.js code you should be using request.query. This will return an object of your query string as a key value pair.

Answer 2

As an alternative, you can use the Mobile Cloud SDK to send REST requests to your Node server on Bluemix.

The Android SDK was designed so that every API returns a Bolts task. This will help you understand your Node responses with much less hassle.
