Python小练习-自动登录人人发送消息并返回好友列表

主要是由urllib，urllib2，cookielib这三个模块。对这三个标准库不熟悉可以学习一下，我也不是很熟系，练习一下。

比如  urllib2 - The Missing Manual

         cookielib and ClientCookie 

主要就是模拟人人登录，通过httpfox抓包来对登录网站的过程进行分析，将密码和发送的消息post到服务器上就可以，用cookielib模块处理cookie，然后就是正则匹配的问题了。

60 users = Loginrenren('youremailaddress',"yourpassword")

61 users.login()

62 users.getfriendlist()

requestToken和_rtk不知道怎么求，查的。

其他不说了，代码不难，忘了谁说的了，代码可以自己解释自己 - -
