nodejs获取当前url和url参数值

var 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=002
console.log(p.protocol); //取到的值是：http: 
console.log( p.hostname);//取到的值是：locahost
console.log(p.host);//取到的值是：localhost:8888
console.log(p.port);//取到的值是：8888
console.log(p.path);//取到的值是：/select?aa=001&bb=002
console.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： 当前URL http://mj_0203.0fees.net/index.php?aa=001&bb=002

document.location:       http://mj_0203.0fees.net/index.php?aa=001&bb=002
document.URL:            http://mj_0203.0fees.net/index.php?aa=001&bb=002
document.location.href:  http://mj_0203.0fees.net/index.php?aa=001&bb=002
self.location.href:      http://mj_0203.0fees.net/index.php?aa=001&bb=002
top.location.href:       http://mj_0203.0fees.net/index.php?aa=001&bb=002
parent.document.location: http://mj_0203.0fees.net/index.php?aa=001&bb=002
top.location.hostname:   mj_0203.0fees.net
location.hostname:       mj_0203.0fees.net
