nodejs實現獲取當前url地址及url各種參數值

   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
