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：
post提交
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");
