采用python实现简单QQ单用户机器人的方法

采用python实现简单QQ单用户机器人的方法如下：

一、首先我们查看一下关于3GQQ的相关协议：
对此，打开一个支持WAP的浏览器，可以使用Firefox的wmlbrowser插件，打开FF后，访问地址 https://addons.mozilla.org/zh-CN/firefox/search/?q=wmlbrowser&cat;=all&x;=17&y;=11

二、进入3GQQ的进行协议分析
3GQQ的地址是：http://pt.3g.qq.com/s?aid=nLogin3gqq 用安装了wmlbrowser插件的FF打开页面后，启用firebug，即可实现监视提交的数据。

三、源代码部分：

    #coding:utf-8
    #基于python2.6版本开发
    import httplib,urllib,os,threading,re
    import sys
    reload(sys)
    sys.setdefaultencoding('utf8')

        try:
          _urld = httplib.urlsplit(url)
          conn = httplib.HTTPConnection(_urld.netloc,80,True,3)
          conn.connect()
          data = urllib.urlencode(data)
          if method=='get':
            conn.putrequest("GET", url, None)
            conn.putheader("Content-Length",'0')
          elif method=='post':

            conn.putheader("Content-Type", "application/x-www-form-urlencoded")

          conn.putheader("Connection", "close")
          conn.endheaders()

          if len(data)>0:
            conn.send(data)
          f = conn.getresponse()
          self.httpBody = f.read().encode('utf8')
          f.close()
          conn.close()
