WWW::Mechanize to access secure website

Question

I have a script I am trying to log into an Oracle EBS page with and I believe I am one line away, (I could be wrong) from doing this. Below is my script and attached is the section of from data I think the answer is there some where.

I think its the submit and submit form line where I think I am failing. But if anyone sees other discrepancies, please let me know. I do see where the username in the script is in the form but not the password. I do believe the script has the right entry, but correct me if I am wrong.

Thanks in advance!

use strict;
use warnings;
use WWW::Mechanize;
use HTTP::Cookies;
my $outfile = "test";
my $url = "http ://url_address:portnumber /OA_HTML/Login";
my $username = 'johndoe';
my $password = 'johndoe123';
my $mech = WWW::Mechanize->new();
$mech->cookie_jar(HTTP::Cookies->new());
$mech->get($url);
$mech->form_id('DefaultFormName');
$mech->field("usernameField", $username);
$mech->field("passwordField", $password);
$mech->submit_form(

form_id => "DefaultFormName",
fields => {
    usernameField => $username,
    passwordField => $password,
    '_FORM_SUBMIT_BUTTON' => "SubmitButtonofEPmL1A",
},
);
my $output_page = $mech->content();
print $output_page;
open(OUTFILE, ">$outfile");
binmode(OUTFILE, ":utf8");`enter code here`
print OUTFILE "$output_page";
close(OUTFILE); 

Form snipet:

Answer 1

WWW::Mechanize does not handle JavaScript. If JavaScript is involved (and it seems so, onclick="submitForm... ), use some other module (eg WWW::Mechanize::Firefox ).

Answer 2

You don't need this lines ( WWW::Mechanize will work with cookies for you automatically):

use HTTP::Cookies;
$mech->cookie_jar(HTTP::Cookies->new());

Next... Are you sure your link have this text : submitForm ? May be you need:

$mech->follow_link( url_regex => qr/submitForm/ );

I recommend to try this code instead (for submit part):

$mech->submit_form(

    form_id => "DefaultFormName",
    fields => {
        usernameField => $username,
        passwordField => $password,
        '_FORM_SUBMIT_BUTTON' => "SubmitButtonofEPmL1A",
    },
};

Update: Another way: you need to use tool like Firefox's HTTPFox add-on and find what data is send to the target site after each request. Next you simply send same data with $mech .
