問題は、Web ページから PDF をダウンロードするために WWW::Mechanize が必要だということです。
編集:しばらくして、コードを作り直しました。WWWW::Mechanize の代わりに LWP::UserAgent を使用しています。MWE は次のとおりです。
#!/usr/bin/env perl
use strict;
use warnings;
use Carp;
use LWP::UserAgent;
use HTTP::Cookies;
use HTML::Form;
use HTTP::Request::Common;
use HTTP::Request::Form;
use Data::Printer;
my $login = 'https://www.wissenschaft-online.de/template/d_meinkonto_controller';
my $cookie_jar = HTTP::Cookies->new();
my $ua = LWP::UserAgent->new;
$ua->cookie_jar($cookie_jar);
push @{ $ua->requests_redirectable }, 'POST';
my $response = $ua->get($login);
my @forms = HTML::Form->parse($response);
$forms[1]->method( q{POST} );
$forms[1]->param(q{user},q{XXX-USER});
$forms[1]->param(q{pass},q{PASSWD});
my $request = $forms[1]->click;
$response = $ua->request($request);
p $response; # print 1
$cookie_jar->extract_cookies( $response );
print $cookie_jar->as_string; # print 2
$response = $ua->get('http://www.spektrum.de/alias/pdf/sdw-2013-5-ges-pdf/1190244', ':content_file' => 'SDW.pdf');
p $response; # print 3
したがって、1 - 資格情報の送信に対する応答を出力します。
