                    {
                        e.printStackTrace();
                        }
                }
            }
            });
    }
}

和我的node.js code是：

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);

谁能帮我在这个问题？

Can anyone help me in this issue?

推荐答案

在您的Node.js code，你应该使用 request.query 。这将返回您的查询字符串的对象作为键值对。

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.
