robot script that logs me in and fills forms automatically

Can someone please tell me how to make a script in php or maybe any other lang. that can log me into any website and fill up a form.
Please post any links or whatever solution that anyone might be having. The form is in .aspx format.
Like suppose I have to submit question to LQ so I will login using this php script and fill up the form
Such a script is what I am looking for.

I recommend writing it in java.

I made once such a program. You just have to analyze the traffic that is being send and received from the webserver.

After that you can open a socket and generate these packets yourself.

I did this in C recently.

The site used the HTTP post method for logging in and used cookies for user/password authentication.

I did what the gent above said.
I used a packet sniffer to see what was going on and then emulated it in my code.

Can someone please throw somelight on as to how should I analyze this traffic. And also how to handle the cookies and other session data
Thank you.

Perl has routines to do stuff like that in the WWW::Mechanize module

I dont know too much about perl.
Can you help me with this WWW::Mechanize module

I dont know perl. Can you help me with WWW::Mechanize module

If you don't know Perl, you might struggle a bit ;-), or of course you can learn it....
It's a very good lang... anyway, here's a short example to get you started

Code:

#!/usr/bin/perl -w



use WWW::Mechanize;    # Automate website interactions

use strict;            # Enforce declarations



    my (

        $mech,      # www::mechanize obj

        $error_msg  # generic msg holder

        );



    # Create Mech Obj

    $mech = WWW::Mechanize->new() or

                        exit_with_error("Mech Obj create failed: $@");



    # Get login screen

    $mech->get($cfg::params{'TGT_URL'}) or

                exit_with_error("Get URL $cfg::params{'TGT_URL'} failed: $@");



#DEBUG

#$error_msg = $mech->uri();

#print "URI: $error_msg\n";



    # Fill in Login credentials and submit form to website

    $mech->submit_form( fields =>

                                {

                                    username => $cfg::params{'USER'},

                                    password => $cfg::params{'PASSWD'}

                                }

                        );

    if( !$mech->success() )

    {

        exit_with_error("Submit Login form failed: $@");

    }



#DEBUG

#$error_msg = $mech->uri();

#print "URI: $error_msg\n";



    # Should have received Phone/Msg form, so

    # fill in nums(s), msg and submit form to website

    $mech->submit_form( fields =>

                                {

                                    numbers => $cfg::params{'PHONE_NUM'},

                                    message => $cfg::params{'MESSAGE'}

                                }

                        );

    if( !$mech->success() )

    {

        exit_with_error("Submit Message form failed: $@");

    }



#DEBUG

#$error_msg = $mech->uri();

#print "URI: $error_msg\n";



    # Should have got "Confirmation" screen: click Continue button

    $mech->click_button(number => 1);

    if( !$mech->success() )

    {

        exit_with_error("Submit Confirmation form failed: $@");

    }

RE: robot script that logs me in and fills forms automatically

I find that http://search.cpan.org is very helpful with function documentation of the modules. The page is here for WWW:Mechanize.
For perl syntax I found this site good (even though it is for windows)
And here is the perl.net.au wiki tutorial
That should give you a reasonably good background to it all
And of course I am glad to help you where I can (I am still learning Perl as well :study: )

OK, Thank you very much. I will try this but can someone tell me something about curl which you find in php
Thanks

tons of info on their website
