记录下来，慢慢学习：
要先获取token，然后再登录

u'http://www.baidu.com/';#https://passport.baidu.com/v2/api/?getapi&class=login&tpl=mn&tangram=true
也可以用这个URL_BAIDU_TOKEN

，测试是否登陆成功，由于cookie自动管理，这里处理起来方便很多#http://tieba.baidu.com/home/main?un=XXXX&fr=index
这个是贴吧个人主页，各项信息都可以在此找到链接teibaUrl

urllib2.urlopen(teibaUrl).read();content
