// note: demo at http://stevenlevithan.com/demo/parseuri/js/assets/parseuri.js
|
|
// note: Does not replace invalid characters with '_' as in PHP, nor does it return false with
|
|
// note: a seriously malformed URL.
|
|
// note: Besides function name, is essentially the same as parseUri as well as our allowing
|
|
// note: an extra slash after the scheme/protocol (to allow file:/// as in PHP)
|
|
// example 1: parse_url('http://username:password@hostname/path?arg=value#anchor');
|
|
// returns 1: {scheme: 'http', host: 'hostname', user: 'username', pass: 'password', path: '/path', query: 'arg=value', fragment: 'anchor'}
|
|
// example 2: parse_url('http://en.wikipedia.org/wiki/%22@%22_%28album%29');
|
|
// returns 2: {scheme: 'http', host: 'en.wikipedia.org', path: '/wiki/%22@%22_%28album%29'}
|
|
// example 3: parse_url('https://host.domain.tld/a@b.c/folder')
|
|
// returns 3: {scheme: 'https', host: 'host.domain.tld', path: '/a@b.c/folder'}
|
|
// example 4: parse_url('https://gooduser:secretpassword@www.example.com/a@b.c/folder?foo=bar');
|
|
// returns 4: { scheme: 'https', host: 'www.example.com', path: '/a@b.c/folder', query: 'foo=bar', user: 'gooduser', pass: 'secretpassword' }
