Seek help posting to www-form-urlencoded . . .

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

UPDATE:

Thank Mortiz and Ikegami. This issue is now resolved, this code works:

#!/usr/bin/perl
use strict;
use warnings;
use LWP::UserAgent;
use HTTP::Request::Common qw( POST );
use Data::Dumper;

my $ua = LWP::UserAgent->new();
my $url = 'http://lobitos.net/cgi-sys/cgiwrap/jlundell/stv-count.py';
my $ballot_file = '/home/hesco/foo/bar/ballot_file.txt';
my $response = $ua->request(POST $url,
    Content_Type => 'multipart/form-data',
         Content => [
           datafile => [ $ballot_file ],
             action => 'Count',
    ],
);

# print Dumper($response->{'_content'});
print Dumper($response->content());

. . . and my original question:

I'm working to upload a file to a webform with LWP. Following a pointer from Utilitarian, shared in the cb, I read this thread and am working to adapt code from there (although some of it looks like narley and required some work just to compile). Nonetheless it seems I'm on to something here.

And my question, what am I missing here?

My test script reads:

#!/usr/bin/perl
use strict;
use warnings;
use LWP::UserAgent;
use Data::Dumper;

my $ua = LWP::UserAgent->new();
my $url = 'http://lobitos.net/cgi-sys/cgiwrap/jlundell/stv-count.py';
my $ballot_file = '/home/hesco/foo/bar/ballot_file.txt';
my $request = (
#         POST => $url,
        action => 'Count',
          name => 'datafile',
  Content_Type => 'multipart/form-data',
       Content => [ 'file' => [ $ballot_file ]] );
my $response = $ua->post($url,$request);

print Dumper($response);

And the form I'm posting against reads:

<form action="/cgi-sys/cgiwrap/jlundell/stv-count.py" enctype="multipa
+rt/form-data" method="post">

<p>Specify an election file: <input type="file" name="datafile" size="
+40"><br>

then <input type="submit" name="action" value="Count"></p>

</form>

My output reads:
