var url = require("url");  //要先加载url模块
var wo=url.parse('https://sdeno.com:8080/zp/js/23.php?123=456&789=999#hhh');
console.log(wo.protocol); // http:
console.log(wo.host); // www.xgllseo.com:8080
console.log(wo.port);// 8080
console.log(wo.hostname);// www.xgllseo.com
console.log(wo.hash);// #hhh
console.log(wo.search);// ?123=456&789=999
console.log(wo.query);// 123=456&789=999
console.log(wo.pathname);// /zp/js/23.php
console.log(wo.path);// /zp/js/23.php?123=456&789=999
console.log(wo.href);// https://sdeno.com:8080/zp/js/23.php?123=456&789=999#hhh

var hh=url.format({
 protocol: 'http:',
 host: 'www.example.com',

console.log(url.parse(hh).href);//http://www.example.com/p/a/t/h?query=string
