我的node.js代码是：
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);
有谁可以帮我解决这个问题？

在Node.js代码中，您应该使用request.query。这将返回查询字符串的对象作为键值对。

作为替代方案，您可以使用Mobile Cloud SDK向Bluemix上的节点服务器发送REST请求。
Android SDK的设计使每个API都返回一个Bolts任务。这将帮助您更轻松地理解您的节点响应。
