=head1 NAME
WWW::Shorten::Metamark - Perl interface to metamark.net
=head1 SYNOPSIS
use WWW::Shorten::Metamark;
use WWW::Shorten 'Metamark';
$short_url = makeashorterlink($long_url);
$long_url = makealongerlink($short_url);
=head1 DESCRIPTION
A Perl interface to the web site metamark.net. Metamark simply maintains
a database of long URLs, each of which has a unique identifier.
=cut
package WWW::Shorten::Metamark;
use 5.006;
use strict;
use warnings;
use base qw( WWW::Shorten::generic Exporter );
our @EXPORT = qw(makeashorterlink makealongerlink);
our $VERSION = '1.91';
use Carp;
=head1 Functions
=head2 makeashorterlink
The function C<makeashorterlink> will call the Metamark web site passing it
your long URL and will return the shorter Metamark version.
=cut
sub makeashorterlink ($)
{
my $url = shift or croak 'No URL passed to makeashorterlink';
my $ua = __PACKAGE__->ua();
my $resp = $ua->post( 'http://metamark.net/api/rest/simple', [
long_url => $url,
] );
return unless $resp->is_success;
return if $resp->content =~ /^ERROR:/;
# I love REST. It's so simple when done properly.
return $resp->content;
}
=head2 makealongerlink
The function C<makealongerlink> does the reverse. C<makealongerlink>
will accept as an argument either the full Metamark URL or just the
Metamark identifier.
If anything goes wrong, then either function will return C<undef>.
=cut
sub makealongerlink ($)
{
my $short_url = shift
or croak 'No Metamark key / URL passed to makealongerlink';
my $ua = __PACKAGE__->ua();
my $resp = $ua->post( 'http://metamark.net/api/rest/simple', [
short_url => $short_url,
] );
return unless $resp->is_success;
return if $resp->content =~ /^ERROR:/;
# I love REST. It's so simple when done properly.
return $resp->content;
}
