This article introduces two methods for javascript to parse URLs into json format. I would like to share them with you. The details are as follows:

Method 1: The simplest method is to use the a tag to The result obtained by implementing

function parseUrl(url){
  var a=document.createElement(&#39;a&#39;);
  a.href=url;
  return {
   protocol:a.protocol.replace(&#39;:&#39;,&#39;&#39;),
   hostname:a.hostname,
   port:a.port,
   path:a.pathname,
   query:(()=>{
    var query=a.search.substr(1);
    var queryArr=query.split(&#39;&&#39;);
    var queryObj={};
    queryArr.forEach((item,index)=>{
      var item=item.split(&#39;=&#39;);
      var key=item[0];
      queryObj[key]=item[1];
    })
    return queryObj;
   })(),
    params:(()=>{
    var params=a.hash.substr(1);
    var paramsArr=params.split(&#39;#&#39;);
    return paramsArr;
    
   })(),

  }
}
var urlObj = parseUrl(&#39;http://www.baidu.com:90/search?name=liyajie&age=12#abc#bbb&#39;)
console.log(urlObj)

Copy after login

Method 2: Through the url module of nodejs

Parsing URLs requires the use of the url module provided by Node.js. It is very simple to use. It uses parse() to parse a string into a Url object:

  &#39;use strict&#39;;
   var url = require(&#39;url&#39;);
   console.log(url.parse(&#39;http://user:pass@host.com:8080/path/to/file?query=string#hash&#39;));

Copy after login

Returned results:

Url {
 protocol: &#39;http:&#39;,
 slashes: true,
 auth: &#39;user:pass&#39;,
 host: &#39;host.com:8080&#39;,
 port: &#39;8080&#39;,
 hostname: &#39;host.com&#39;,
 hash: &#39;#hash&#39;,
 search: &#39;?query=string&#39;,
 query: &#39;query=string&#39;,
 pathname: &#39;/path/to/file&#39;,
 path: &#39;/path/to/file?query=string&#39;,
 href: &#39;http://user:pass@host.com:8080/path/to/file?query=string#hash&#39; }
