获取url参数

// 访问http://localhost:3000/home?id=001&name=tom
var http = require(‘http‘);
var url = require(‘url‘);
http.createServer(function(req, res) {
    var arg = url.parse(req.url).query; //方法一arg => id=001&name=002
   var arg2 = url.parse(req.url, true).query; //方法二arg => { id: ‘001‘, name: ‘tom‘ }
    console.log(arg2); 
}).listen(3000); //建立服务器并监听端口

function getQueryString(name) { 
var reg = new RegExp("(^|&)" + name + "=([^&]*)(&|$)", "i"); 
var r = window.location.search.substr(1).match(reg); 
if (r != null) return unescape(r[2]); return null; 
} 

//获取url参数page
var page = getQueryString("page");
console.log(page);
