nodejs獲取當前url和url參數值

//需要使用的模塊 http

url
當前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
//然后就可以根據所得到的數據處理了

}).listen(8888);//建立服務器並監聽端口

獲取特定url參數值

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
在此值得注意的是當語句是 var p = URL.parse(testUrl, true) 時,p.query則返回的是如：{aa:'001'}這樣的對象，直接打印p.query則返回 [object Object]，這時我們可以這樣寫： 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的獲取方法：
當前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
