// Get、Post 超文本传输协议（HTTP）的设计目的是保证客户端机器与服务器之间的通信。 在客户端和服务器之间进行请求-响应时，两种最常被用到的方法是：GET 和 POST。 GET - 从指定的资源请求数据。（一般用于获取数据） POST - 向指定的资源提交要被处理的数据。（一般用于提交数据
// 获取 GET 传值
// var urlinfo=url.parse(req.url,true);
// urlinfo.query;
// //获取 POST 传值：
// // var postData = '';
// // 数据块接收中
// req.on('data', function (postDataChunk) {
// postData += postDataChunk;
// });
// // 数据接收完毕，执行回调函数
// req.on('end', function () {
// try {
// postData = JSON.parse(postData);
// } catch (e) {
// }
// req.query = postData;
// console.log(querystring.parse(postData));
