homer123 has asked for the wisdom of the Perl Monks concerning the following question:

Hi I am a newbie wrt javascript/perl. I am trying to use perl to login to the playboy website :-) where I have a *legal* paid subscription. It uses a javascript based login and I am using WWW::Mechanize The code I am using is as follows *********************************** 
use LWP::UserAgent;
use HTTP::Cookies;
use WWW::Mechanize;


my $start_page = 'https://secure2.playboy.com/security/loginStart.do?s
+c_target=cyber.playboy.com';
my $mech = WWW::Mechanize->new();

my $mech = WWW::Mechanize->new( cookie_jar =>  "lwpcookies.txt");
my $mech = WWW::Mechanize->new( agent=>"Mozilla/5.0 (X11; U; Linux i68
+6; en-US; rv:1.7) Gecko/20040918 Firefox/0.9.3 " );


$mech->get( $start_page );

if ($mech->success()==1) {
        print "Success \n";
        }

$mech->submit_form(
        form_name => 'loginForm',
        fields    => {
                username  => 'xxxx',
                password  => 'xxxx',
                savedPWAction => 'on',
                submitButton => 'ENTER THE CLUB'
        }
);
#$mech->click_button(name => 'submitButton');
#$button='submitButton';

$mech->click;

$result = $mech->success();

if ($result == 1){
        print "Success";
        }
else {
        print "Fail";
        }

    Hi
    • When you're new, 
      use strict;
use warnings;
use diagnostics;

      [download]
    • There is no javascript, there is only HTTP
    • use LWP::Debug qw(+);

    MJD says "you can't just make shit up and expect the computer to know what you mean, retardo!"
    I run a Win32 PPM repository for perl 5.6.x and 5.8.x -- I take requests (README).

      Hi PodMaster, Thanks for the swift kick in the butt. :-) I have added strict, warning and diagnostics. I have cleaned up the really stupid mistakes that I had. I can now see it using the cookies unlike before. I was able to successfully fill in the form and retrieve the content i.e my submit_form() method returns a sucess. The content is as follows. 
      <META HTTP-EQUIV="Refresh" CONTENT="0;URL=https://secure2.playboy.com/
+security/cookieGenerator.do">

<html>
<body bgcolor="#000000" >
</body>
</html>

      [download]

      This is the content I get when I use a regular browser also. So I think the code works until this point. In the regular browser it then goes to the next page which is also a https page. The link for the page is in the variable $member_gateway. I tried downloading that next but when I try that I get the same login page again.
      I did read your README. I use linux. so I wont be able to use your repository.
      Thank you for your original comments
      Here is my new code 
      #!/usr/bin/perl

use HTTP::Cookies;
use WWW::Mechanize;
use strict;
use warnings;
use diagnostics;
use LWP::Debug qw(+);  #Shows the transaction taking place

my $start_page = 'https://secure2.playboy.com/security/loginStart.do?s
+c_target=cyber.playboy.com';
my $mech = WWW::Mechanize->new( agent=>"Mozilla/5.0 (X11; U; Linux i68
+6; en-US; rv:1.7) Gecko/20040918 Firefox/0.9.3 " );

my $cookie_jar = HTTP::Cookies->new(file => './lwp_cookies.dat', autos
+ave => 1,);  #Creating a cookie jar

$mech->cookie_jar($cookie_jar); #Attaching cookie jar to the user agen
+t i.e $mech
$mech->get( $start_page );

if ($mech->success()==1) {
        print "Success \n";
        }

$mech->submit_form(
        form_name => 'loginForm',
        fields    => {
                username  => 'xxxx',
                password  => 'xxxx',
                savedPWAction => 'on',
        }
);

if ($mech->success()==1) {
        print "Success \n";
        }
print $mech->content();

my $member_gateway='https://secure2.playboy.com/gateway/gateway.do ';
$mech->get($member_gateway);

print $mech->content();

      Do you have any suggestions for downloading the next page ?

        A few comments...

        If the META refresh is directing you to 'https://secure2.playboy.com/security/cookieGenerator.do', why are you get()ing 'https://secure2.playboy.com/gateway/gateway.do '?

        If you meant after hitting 'cookieGenerator.do' you are then redirected to 'gateway.do ', are you sure that trailing space is supposed to be there?

        Have you looked at HTTP::Recorder (alt.)? It could make your life a whole lot easier. :-)

    Psssst.. this is a monastery. We will not help you indulge in your sins of the flesh, although Randal's swimsuit pic collector is acceptable.

      With the help of the perl monks I was successfully able to get a script that will help me download pics from pb website
      Here is the final script. It works for me and it comes with no guarantee it will work for you.
      A VERY SPECIAL THANKS to perl monk "kanji" for guiding this newbie.
