nodejs实现获取当前url地址及url各种参数值

复制代码 代码如下:

//需要使用的模块 http   url
当前url   http://localhost:8888/select?aa=001&bb=002
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

复制代码 代码如下:

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

复制代码 代码如下:

http://mj_0203.0fees.net/index.php?aa=001&bb=002
document.location:        http://mj_0203.0fees.net/index.php?aa=001&bb=002
