javascript将url解析为json格式的两种方法

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' }
