Regex for a URL Connection String

Is there a known JavaScript regular expression to match an entire URL Connection String?

protocol://user:password@hostname:12345/segment1/segment2?p1=val1&p2         


        

Answer 1

Something like this ?

function url2obj(url) {
    var pattern = /^(?:([^:\/?#\s]+):\/{2})?(?:([^@\/?#\s]+)@)?([^\/?#\s]+)?(?:\/([^?#\s]*))?(?:[?]([^#\s]+))?\S*$/;
    var matches =  url.match(pattern);
    var params = {};
    if (matches[5] != undefined) { 
       matches[5].split('&').map(function(x){
         var a = x.split('=');
         params[a[0]]=a[1];
       });
    }

    return {
        protocol: matches[1],
        user: matches[2] != undefined ? matches[2].split(':')[0] : undefined,
        password: matches[2] != undefined ? matches[2].split(':')[1] : undefined,
        host: matches[3],
        hostname: matches[3] != undefined ? matches[3].split(/:(?=\d+$)/)[0] : undefined,
        port: matches[3] != undefined ? matches[3].split(/:(?=\d+$)/)[1] : undefined,
        segments : matches[4] != undefined ? matches[4].split('/') : undefined,
        params: params 
    };
}

console.log(url2obj("protocol://user:password@hostname:12345/segment1/segment2?p1=val1&p2=val2"));
console.log(url2obj("http://hostname"));
console.log(url2obj(":password@"));
console.log(url2obj("?p1=val1"));
console.log(url2obj("ftp://usr:pwd@[FFF::12]:345/testIP6"));
