用Python发送和接收HTTP请求，同时需要发送会话cookie

Question

我正在测试我服务器上的登录功能（在失败尝试超过一定次数后会自动封禁IP）。我找到了一段简单的Python脚本，可以发送HTTP请求，代码如下：

import urllib, urllib2, re, os, sys, cookielib

def main():
    host = 'http://192.168.1.133/intro.php'
    user_agent = 'Mozilla/5.0 (Windows; U; Windows NT 6.1; ru; rv:1.9.2.3) Gecko/20100401 Firefox/4.0 (.NET CLR 3.5.30729)'
    headers = {'User-Agent': user_agent}
    username = 'admin'
    error =  '<p class="highlight">Login failed. Please try again.</p>'
    word_file = 'pass.txt'
    word_pos = 1

    file = open(word_file, 'r')
    word_list = file.read().split('\n')
    file.close

    for word in word_list:
        form = {'username': username, 'password': word}

        print 'Tring password: %s (%d/%d)' % (word, word_pos, len(word_list))
        word_pos = word_pos + 1

        data = urllib.urlencode(form)
        request = urllib2.Request(host, data, headers)
        response = urllib2.urlopen(request)

        size = response.headers.get("content-length")

        #print 'response %s' % (response.read())
        #print 'size: %s' % (size)

        if not re.search(error, response.read()):
            print 'Login Combination: [%s:%s]' % (username, word)
            save_combo = open('login comination.txt', 'w')
            save_combo.write(username + ':' + word)
            save_combo.close
            break

if __name__ == '__main__':
    main()

但是我的intro.php文件是这样的：

$a = session_id();
if ($a == '') session_start();

我需要发送会话cookie。这是一个典型的登录请求：

POST /intro.php HTTP/1.1
Host: 192.168.1.133
User-Agent: Mozilla/5.0 (Windows; U; Windows NT 6.1; en-GB; rv:1.9.2.13) Gecko/20101203 AlexaToolbar/alxf-2.01 Firefox/3.6.13

我想创建cookie变量，这样我就可以在每次请求中发送cookie，而不仅仅是现在发送的POST、Host和User-Agent。我刚安装了Python，所以不太确定怎么使用cookielib。
