NODEJS, as follows: 

var http = require(&#39;http&#39;);
var querystring = require(&#39;querystring&#39;);
var server = http.createServer(function (req,res) {
  //如果你的访问地址是这个，并且请求类型是post
  if(req.url == &#39;/dopost&#39; && req.method.toLowerCase() == &#39;post&#39;){
    var allData = &#39;&#39;;

    //接受了一小段，可能就给别人去服务了。防止一个过大的表单阻塞了整个进程
    req.addListener(&#39;data&#39;,function (chunk) {
      allData += chunk;
      console.log(&#39;数据：&#39;+allData);
    });
    //全部传输完毕
    req.addListener(&#39;end&#39;,function () {
      var oData = allData.toString();
      var iDa = querystring.parse(oData);
      res.end(&#39;success&#39;);
      console.log(iDa);
      console.log(iDa.like);
      console.log(iDa.name);
      console.log(iDa.sex);
    });
  }
