//需要使用的模块 http   url当前url   http://localhost:8888/select?aa=001&bb=002var http = require('http');var URL = require('url');http.createServer(function(req, res){   var arg = url.parse(req.url).query;  //方法一arg => aa=001&bb=002   var arg = url.parse(req.url, true).query;  //方法二arg => { aa: '001', bb: '002' }   console.log(arg.aa);//返回001   console.log(arg.bb);//返回002   //然后就可以根据所得到的数据处理了}).listen(8888);//建立服务器并监听端口

 

获取特定url参数值

var testUrl =  'http://localhost:8888/select?aa=001&bb=002';var p = URL.parse(testUrl); console.log(p.href); //取到的值是：http://localhost:8888/select?aa=001&bb=002console.log(p.protocol); //取到的值是：http: console.log( p.hostname);//取到的值是：locahostconsole.log(p.host);//取到的值是：localhost:8888console.log(p.port);//取到的值是：8888console.log(p.path);//取到的值是：/select?aa=001&bb=002console.log(p.hash);//取到的值是：null console.log(p.query);// 取到的值是：aa=001

 

在此值得注意的是当语句 是 var p = URL.parse(testUrl, true) 时,p.query则返回的是如：{aa:'001'}这样的对象， 直接打印p.query则返回 [object Object]，这时我们可以这样 写： console.log(

p.query.aa); //取到的值是：001

console.log( 

p.pathname);

//取到的值是：/select

下面附上js的获取方法：
