Hello, I'm brand new to using the WWW::Facebook::API and am trying to write a simple program to access my friends list. I'm not even trying to build a web interface at this point - I'm trying to do everything from the command line. I have already registered my application on the Facebook developers website and have my API key and secret key. Here is the code I have so far:

#!/usr/bin/perl -w
use strict;
use WWW::Facebook::API;
use Data::Dumper;

my $api_key = '###############';
my $secret = '################################';

my $client = WWW::Facebook::API->new(
    desktop => 0,
    api_key => $api_key,
    secret => $secret,
);

$client->auth->get_session( $client->auth->create_token);
my $friends_perl = $client->friends->get;
print Dumper $friends_perl;

Running the above generates the following:

Error during REST auth.getSession call:
params = 
        api_key:593556437357708
        auth_token:ff943e34a13a09db5183759758c1114e
        call_id:1379735054.13075
        format:JSON
        method:facebook.auth.getSession

response =

+acebook.auth.getSession"},{"key":"v","value":"1.0"},{"key":"sig","val
+ue":"413ab39f44795539e74abd4de1be79ed"}]}

I'm not even sure where to start on this one. I know the WWW::Facebook::API has several other input parameters. Do I need to specify session_key, session_expires, session_uid? Does the fact that I'm only interested in using this app from the command line for now make a difference? Also I'm only interested in accessing my own data. Can I hard code my login info into the script somehow?
