帮帮忙解决一下网站自动登陆的问题

请各位帮忙看看下面这段代码哪有问题,我不怎么试,打开aa.html页面都是说输入的用户名、密码错误!  我已经看了好几天了但
就是找不到问题原因

use LWP 5.64;
  use URI;
  use CGI qw(:standard);
  use HTTP::Cookies;
  use strict;

open (ABC,">E:/aa.html");
my $ua = LWP::UserAgent->new;  
my   $cookie_jar = HTTP::Cookies->new;

my $header = HTTP::Headers->new(
      Date         => 'Sat, 19 Jul 2008 20:38:00 GMT',
      Content_Type => 'text/html; charset=UTF-8',
      Content_Base => 'http://192.168.240.105:8080/pebble/');
my $loginurl='http://192.168.240.105:8080/pebble/j_security_check';
my $loginconten="j_username=dianqiang.yang&j_password=780602,.";
my $request = HTTP::Request->new(POST=>$loginurl,$header,$loginconten);
$cookie_jar->add_cookie_header($request);  

my $response = $ua->request($request);
$cookie_jar->extract_cookies($response);
print ABC $response->content;
close (ABC)

这么长代码。。。
为啥不说说具体思路呢
1、先登陆网站http://192.168.240.105:8080/pebble/j_security_check,自动输入用户名及密码;
2、实现登陆后找到对应连接并把系统的log日志放在对应页面的form中;
3、完成;

放上来的代码只停留在第一步,我双击此脚本生成的aa.html文件,打开的页面总是提示用户名及密码错误
咋没人帮着看看呀,急死我了!
