Perl 在GeoServer上使用WWW:：Mechanize时，会话过期

我尝试使用WWW：：Mechanize来自动化与GeoServer的会话

GeoServer附带了一个restapi，可以与curl一起使用。但目前，不可能使用RESTAPI为ImageMosacJDBC创建数据存储，因此我想使用Perl脚本添加新的光栅数据源。它基于WWW：：Mechanize

但它失败了，有这样一条信息：

your session has expired.

脚本就在下面

#!/usr/bin/perl

use strict;
use warnings;

use WWW::Mechanize;
use HTML::TreeBuilder;
use HTML::Tree;
use Getopt::Long;
use HTTP::Cookies;

my %CONF = (
    username     => 'admin',
    password     => 'geoserver',
);

GetOptions( \%CONF, "username=s", "password=s" ) or die "Bad options";

my $netloc   = "193.55.67.151:8080";
my $url      = "http://$netloc/geoserver/web/?wicket:bookmarkablePage=:org.geoserver.web.GeoServerLoginPage";

my $cookie_jar = HTTP::Cookies->new;
my $agent      = WWW::Mechanize->new( cookie_jar => $cookie_jar );
$agent->agent('User-Agent=Mozilla/5.0 (X11; Ubuntu; Linux x86_64; rv:44.0) Gecko/20100101 Firefox/44.0');

# auth
$agent->get($url);
die $agent->res->status_line unless $agent->success;
$agent->set_fields(%CONF);
$agent->submit;
die $agent->res->status_line unless $agent->success;

# adding data store
$url = "http://$netloc/geoserver/web?wicket:bookmarkablePage=:org.geoserver.web.data.store.NewDataPage";
my $content = $agent->get($url);
die $agent->res->status_line unless $agent->success;
my $tree    = HTML::Tree->new();
$tree->parse($content);
print $agent->content;

# storeform
$url = "http://$netloc/geoserver/web/?wicket:interface=:5:storeForm::IFormSubmitListener::";
my $content = $agent->post($url);
die $agent->res->status_line unless $agent->success;
my $tree    = HTML::Tree->new();
$tree->parse($content);
print $agent->content;

# newdatapage
$url = "http://$netloc/geoserver/web/?wicket:interface=:6::::";
my $ref = "http://$netloc/geoserver/web/?wicket:bookmarkablePage=:org.geoserver.web.data.store.NewDataPage";
my $content = $agent->get( $url, referer => $ref);
die $agent->res->status_line unless $agent->success;
my $tree    = HTML::Tree->new();
$tree->parse($content);
print $agent->content;

我看不出问题出在哪里。。。特别是，我使用WireShark检查HTTP交换，但对我来说一切都很好。例如，JSESSIONID cookie被正确解救。

尝试设置超时参数，同时声明$agent

在程序的哪个步骤？
