//引入http模块
var http=require('http');
var url=require('url');
var ejs=require('ejs');  //ejs模块(第三方模块)  用于视图模板解析
var querystring = require('querystring');  //querystring模块

http.createServer(function(req,res){
	res.writeHead(200,{"Content-Type":"text/html;charset='utf-8'"});
	//获取get 还是post请求
	var method=req.method.toLowerCase();
	//console.log(method);
	var pathname=url.parse(req.url,true).pathname;
	if(pathname=='/dologin' && method=='get'){  //get传值
        console.log(url.parse(req.url,true).query);  // true表示将get提交的数据转成Json格式 { username: '123', password: '456' }
        res.end('dologin');
	}else if(pathname=='/dologin' && method=='post'){  //post传值
		var postStr='';
		//该方式只能获取post提交的数据
		req.on('data',function(postData){
			postStr+=postData;  // username=123&password=456
            var postJson = querystring.parse(postStr);  //username=123&password=456 转成Json对象
			console.log(postJson);  //Json对象:{ username: '123', password: '456' }
			res.end("post的数据(username):"+postJson.username+"<br />post的数据(password):"+postJson.password);
		})
