uri::url
URI::URL(3) User Contributed Perl Documentation URI::URL(3)NAME
URI::URL - Uniform Resource Locators
SYNOPSIS
$u1 = URI::URL->new($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" class that used to
be distributed with the libwww-perl library.
The following differences compared to the "URI" class interface exist:
o The URI::URL module exports the url() function as an alternate constructor interface.
o The constructor takes an optional $base argument. The "URI::URL" class is a subclasses of "URI::WithBase".
o The URI::URL->newlocal class method is the same as URI::file->new_abs
o URI::URL::strict(1)
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.
o $url->abs and $url->rel have an optional $base argument. See URI::WithBase.
o $url->frag; same as $uri->fragment
o $url->keywords; same as $uri->query_keywords;
o $url->localpath with friends map to $uri->file
o $url->address and $url->encoded822addr; same as $uri->to for mailto URI.
o $url->groupart method for news URI.
o $url->article; same as $uri->message
