JavaScript utilise deux méthodes pour analyser l'URL au format json.

function parseUrl(url){
  var a=document.createElement('a');
  a.href=url;
  return {
   protocol:a.protocol.replace(':',''),
   hostname:a.hostname,
   port:a.port,
   path:a.pathname,
   query:(()=>{
    var query=a.search.substr(1);
    var queryArr=query.split('&');
    var queryObj={};
    queryArr.forEach((item,index)=>{
      var item=item.split('=');
      var key=item[0];
      queryObj[key]=item[1];
    })
    return queryObj;
   })(),
    params:(()=>{
    var params=a.hash.substr(1);
    var paramsArr=params.split('#');
    return paramsArr;
    
   })(),

  }
}
var urlObj = parseUrl('http://www.baidu.com:90/search?name=liyajie&age=12#abc#bbb')
console.log(urlObj)

  'use strict';
   var url = require('url');
   console.log(url.parse('http://user:pass@host.com:8080/path/to/file?query=string#hash'));

Url {
 protocol: 'http:',
 slashes: true,
 auth: 'user:pass',
 host: 'host.com:8080',
 port: '8080',
 hostname: 'host.com',
 hash: '#hash',
 search: '?query=string',
 query: 'query=string',
 pathname: '/path/to/file',
 path: '/path/to/file?query=string',
 href: 'http://user:pass@host.com:8080/path/to/file?query=string#hash' }
