const url = require("url");
var urlstr = "http://localhost:8888/bb";
var urlobj = url.parse(urlstr); 
console.log(urlobj);
/*
Url {
 protocol: 'http:',
 slashes: true,
 auth: null,
 host: 'localhost:8888',
 port: '8888',
 hostname: 'localhost',
 hash: null,
 search: '"htmlcode">

query: { name: ‘bigbear', memo: [ ‘helloworld', ‘helloC' ] },


例子如下：


const url = require("url");
var urlstr = "http://localhost:8888/bb";
console.log(
 url.parse(urlstr, true)
)
/*
Url {
 protocol: 'http:',
 slashes: true,
 auth: null,
 host: 'localhost:8888',
 port: '8888',
 hostname: 'localhost',
 hash: null,
 search: '"htmlcode">

const url = require("url");
var urlstr = "//foo/bar ";
console.log(
 url.parse(urlstr, true,true)
)
/*
 输出：Url {
 protocol: null,
 slashes: true,
 auth: null,
 host: 'foo',
 port: null,
 hostname: 'foo',
 hash: null,
 search: '',
 query: {},
 pathname: '/bar',
 path: '/bar',
 href: '//foo/bar' }
*/


const url = require("url");
var urlstr = "//foo/bar ";
console.log(
 url.parse(urlstr)
)
/*
输出：
Url {
 protocol: null,
 slashes: null,
 auth: null,
 host: null,
 port: null,
 hostname: null,
 hash: null,
 search: null,
 query: null,
 pathname: '//foo/bar',
 path: '//foo/bar',
 href: '//foo/bar' }
*/


url模块化
将一个url对象转换成一个url字符串，url对象中的属性为url.parse()产生的对象的属性。 


url.parse()和url.format()互为逆操作。
例子如下：


const url = require("url");
var Urlobj = {
 protocol: 'http:',
 slashes: true,
 auth: null,
 host: 'localhost:8888',
 port: '8888',
 hostname: 'localhost',
 hash: null,
 search: '"color: #ff0000">路径解析：url.resolve(from, to)

url.resolve()方法解决了目标URL相对于基本URL的方式类似于Web浏览器解决锚标记href。
官方手册例子：


url.resolve('/one/two/three', 'four');  
// '/one/two/four'

url.resolve('http://example.com/', '/one'); 
// 'http://example.com/one'

url.resolve('http://example.com/one', '/two'); 
// 'http://example.com/two'
