URI::[URL(3pm)](https://www.chedong.com/phpMan.php/man/URL/3pm/markdown)         User Contributed Perl Documentation        URI::[URL(3pm)](https://www.chedong.com/phpMan.php/man/URL/3pm/markdown)

NAME
       [URI::URL](https://www.chedong.com/phpMan.php/perldoc/URI%3A%3AURL/markdown) - Uniform Resource Locators

SYNOPSIS
        $u1 = [URI::URL](https://www.chedong.com/phpMan.php/perldoc/URI%3A%3AURL/markdown)->new($str, $base);
        $u2 = $u1->abs;

DESCRIPTION
       This module is provided for backwards compatibility with modules that
       depend on the interface provided by the "[URI::URL](https://www.chedong.com/phpMan.php/perldoc/URI%3A%3AURL/markdown)" class that used to
       be distributed with the libwww-perl library.

       The following differences exist compared to the "URI" class interface:

       o  The [URI::URL](https://www.chedong.com/phpMan.php/perldoc/URI%3A%3AURL/markdown) module exports the url() function as an alternate
          constructor interface.

       o  The constructor takes an optional $base argument.  The "[URI::URL](https://www.chedong.com/phpMan.php/perldoc/URI%3A%3AURL/markdown)"
          class is a subclass of "[URI::WithBase](https://www.chedong.com/phpMan.php/perldoc/URI%3A%3AWithBase/markdown)".

       o  The [URI::URL](https://www.chedong.com/phpMan.php/perldoc/URI%3A%3AURL/markdown)->newlocal class method is the same as
          [URI::file](https://www.chedong.com/phpMan.php/perldoc/URI%3A%3Afile/markdown)->new_abs.

       o  [URI::URL](https://www.chedong.com/phpMan.php/perldoc/URI%3A%3AURL/markdown)::[strict(1)](https://www.chedong.com/phpMan.php/man/strict/1/markdown)

       o  $url->print_on method

       o  $url->crack method

       o  $url->full_path: same as ($uri->abs_path || "/")

       o  $url->netloc: same as $uri->authority

       o  $url->epath, $url->equery: same as $uri->path, $uri->query

       o  $url->path and $url->query pass unescaped strings.

       o  $url->path_components: same as $uri->path_segments (if you don't
          consider path segment parameters)

       o  $url->params and $url->eparams methods

       o  $url->base method.  See [URI::WithBase](https://www.chedong.com/phpMan.php/perldoc/URI%3A%3AWithBase/markdown).

       o  $url->abs and $url->rel have an optional $base argument.  See
          [URI::WithBase](https://www.chedong.com/phpMan.php/perldoc/URI%3A%3AWithBase/markdown).

       o  $url->frag: same as $uri->fragment

       o  $url->keywords: same as $uri->query_keywords

       o  $url->localpath and friends map to $uri->file.

       o  $url->address and $url->encoded822addr: same as $uri->to for mailto
          URI
