=head1 NAME
WWW::Shorten::TinyURL - Perl interface to tinyurl.com
=head1 SYNOPSIS
use WWW::Shorten::TinyURL;
use WWW::Shorten 'TinyURL';
$short_url = makeashorterlink($long_url);
$long_url = makealongerlink($short_url);
=head1 DESCRIPTION
A Perl interface to the web site tinyurl.com. TinyURL simply maintains
a database of long URLs, each of which has a unique identifier.
=cut
package WWW::Shorten::TinyURL;
use 5.006;
use strict;
use warnings;
use base qw( WWW::Shorten::generic Exporter );
our @EXPORT = qw( makeashorterlink makealongerlink );
our $VERSION = '1.90';
use Carp;
=head1 Functions
=head2 makeashorterlink
The function C<makeashorterlink> will call the TinyURL web site passing
it your long URL and will return the shorter TinyURL version.
=cut
sub makeashorterlink ($)
{
my $url = shift or croak 'No URL passed to makeashorterlink';
my $ua = __PACKAGE__->ua();
my $tinyurl = 'http://tinyurl.com/api-create.php';
my $resp = $ua->post($tinyurl, [
url => $url,
source => "PerlAPI-$VERSION",
]);
return undef unless $resp->is_success;
my $content = $resp->content;
return undef if $content =~ /Error/;
if ($resp->content =~ m!(\Qhttp://tinyurl.com/\E\w+)!x) {
return $1;
}
return;
}
=head2 makealongerlink
The function C<makealongerlink> does the reverse. C<makealongerlink>
will accept as an argument either the full TinyURL URL or just the
TinyURL identifier.
If anything goes wrong, then either function will return C<undef>.
=cut
sub makealongerlink ($)
{
my $tinyurl_url = shift
or croak 'No TinyURL key / URL passed to makealongerlink';
my $ua = __PACKAGE__->ua();
$tinyurl_url = "http://tinyurl.com/$tinyurl_url"
unless $tinyurl_url =~ m!^http://!i;
my $resp = $ua->get($tinyurl_url);
return undef unless $resp->is_redirect;
my $url = $resp->header('Location');
return $url;
}
1;
__END__
=head2 EXPORT
