假设URL为：http://localhost:8888/select?name=a&id=5
JavaScript代码
http.createServer(function(request,response){            var pathname = url.parse(request.url).pathname;  //pathname => select                        var arg = url.parse(request.url).query;          //arg => name=a&id=5            console.log("Request for " + arg );            var str = querystring.parse(arg);                //str=> {name:'a',id:'5'}                        var arg1 = url.parse(request.url, true).query;   //arg1 => {name:'a',id:'5'}            console.log("Request for " + arg1 );                        var name = querystring.parse(arg).name;         //name => a            console.log("name = "+name);                console.log("Request for " + pathname + " received.");        }).listen(8888);     
//querystring.parse(arg)   => { name: 'a', id: '5' }
var url = require('url');var a = url.parse('http://example.com:8080/one?a=index&t=article&m=default');console.log(a); //输出结果：{     protocol : 'http' ,    auth : null ,    host : 'example.com:8080' ,    port : '8080' ,    hostname : 'example.com' ,    hash : null ,    search : '?a=index&t=article&m=default',    query : 'a=index&t=article&m=default',    pathname : '/one',    path : '/one?a=index&t=article&m=default',    href : 'http://example.com:8080/one?a=index&t=article&m=default'}
