Https POST sample code

Hmmm...

#!/usr/bin/perl

# requires crypt-ssleay installed
# OR ERR = 501 Protocol scheme 'https' is not supported
# SEE : http://www.linpro.no/lwp/
# windows: ppm install crypt-ssleay [ tested on win98, apache1.3.9, perl 5.60 ]
# Linux : Crypt-SSLeay-0.27.tar.gz -- read notes requires openssl... basically more required

print "Content-type: text/html\n\n";

use HTTP::Request::Common qw(POST GET);
use HTTP::Headers;
use LWP::UserAgent;

# this is the info we are POST-ing to the script
$A = "Hello";
$B = "World";
$C = "I am";
$D = "Here";

# set up the stuff
my $ua = LWP::UserAgent->new();

# Set our own user-agent string!
$ua->agent("PerlZilla/v1.01 RHLinux");

my $url = "https://www.YourTarget.com/cgi-bin/file.cgi";
# file.cgi should just return the data sent for this test

# These seem to be like <input type=text name=A value=$A > off a form...
my $req = POST $url, [
A => "$A",
B => "$B",
C => "$C",
D => "$D" # no comma here Eh !
];

# Fire the cannon now !
my $res = $ua->request($req);

# Get the error back from the server if any
my $err = $res->status_line;
# Get server body text, $_ used in regexp on next line
$_ = $res->as_string;

if (/Illegal Operation/ig || $err != 200) {
print "Server returned error: $err\n";
exit 1;
}

# Just print the whole wack of stuff
print "$_";
# RAW info back for debug -- contains header stuff

exit 0;

If you're in windows and want LWP and SSL, try this: http://johnbokma.com/perl/https.html
The kicker is the non-standard ppd at http://theoryx5.uwinnipeg.ca/ppms/Crypt-SSLeay.ppd. I guess it isn't included by default so ActiveState doesn't have to worry about encryption exportation laws?

After that's installed, LWP works transparently with SSL. The ppd copied a pair of DLL's down to perl's bin directory (in path). In my case, I needed to upload a file, a normal text parameter, and post over SSL with basic http authentication. First the html form, then the Perl code to post to it.

Code:

<form enctype="multipart/form-data" action="https://url.to/post/to" 
		method="post">
	File to process: <input name="FileParamName" type="file"><br>
	File to process: <input name="FileParamName" type="file"><br>
	File to process: <input name="FileParamName" type="file"><br>
	Other form input: 
	<input name="FileParamName" value="A simple form input value"><br>
	<input type="submit" value="Upload">
</form>

Code:

use LWP::UserAgent;
use HTTP::Request::Common;
my $ua = LWP::UserAgent->new;
my $req = POST(
      'https://url.to/post/to',
      Content_Type => 'form-data',
      Content      => [ NormalParamName => 'A simple form input value',
                        FileParamName   => ['file-to-upload.txt'],
                      ],
);
$req->authorization_basic('username', 'password');
print $ua->request($req)->as_string;

I just had to poke at this today and figured I'd share.
