• nodejs获取当前url和url参数值


    //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


    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
