1.Node.js 中 moudle.exprots 的用法：
如果暴露一个类， 就用module.exprots 。
1 /** 2 * Created by aytsoft on 2016/4/25. 3 */ 4 /*如果是暴露一个类 就用moudle.exprots = 类名*/ 5 function Pepole(name, age){ 6 this.name = name; 7 this.age = age; 8 9 } 10 Pepole.prototype = { 11 constructor:Pepole, 12 getMsg :function(){ 13 console.log(this.name + " "+ this.age); 14 } 15 } 16 module.exports = Pepole;
2. querystring 的简单用法：

1 /** 2 * Created by aytsoft on 2016/4/25. 3 */ 4 var http = require("http"); 5 var queryString = require("querystring"); 6 7 8 var server = http.createServer(function(req, res){ 9 if(req.url =="/favicon.ico"){ 10 return; 11 } 12 if(req.url=="/userData" && req.method.toLowerCase()=="post"){ 13 var maindata; 14 req.addListener("data", function(chunk){ 15 maindata += chunk; 16 console.log(chunk); 17 }); 18 req.addListener("end", function(){ 19 var obj = queryString.parse(maindata) 20 console.log(obj); 21 console.log(obj.name); 22 console.log(obj.sex); 23 res.end("hello"); 24 25 }); 26 27 } 28 }).listen(3000,"127.0.0.1");
