這篇文章主要介紹了nodejs實現獲取當前url地址及url各種參數值,本文直接給出代碼實例,需要的朋友可以參考下
代碼如下:
//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
//然後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
代碼如下:
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
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
代碼如下:
http://mj_0203.0fees.net/index.php?aa=001&bb=002
document.location: http://mj_0203.0fees.net/index.php?aa=001&bb=002
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
