Hi all,

I'm attempting to write a Perl script that can upload a file to a web server based on the following very simple file upload form (URL redacted):
<form enctype="multipart/form-data" action="http://example.com" method +="post"> <input type="file" size="50" name="file_0"/><br /><br /> <input type="submit" value="Attach File(s)" name="confirm"/> </form>

And here's my Perl code (URL, username, and password redacted):
use strict; use warnings; use LWP::UserAgent; use HTTP::Request::Common; my $userAgent = LWP::UserAgent->new(); my $request = HTTP::Request->new(POST 'http://example.com', Content_Ty +pe => 'multipart/form-data', Content => [file_0 => ['options2.txt']]) +; $request->authorization_basic('username', 'password'); my $response = $userAgent->request($request); print $response->error_as_HTML . "\n" if $response->is_error;

This gives me a 400 "URL missing" error from the web server. Quite frankly, I have no idea what I'm doing wrong. I'm not a Perl noob, but I've never had occasion to use LWP::UserAgent or HTTP::Request, so I'm a noob in that sense.

Any ideas what I'm doing wrong or how I can debug?
