由于需要登录后访问页面，所以这里需要使用cookie进行session跟踪
'''

cookie = cookielib.CookieJar()                        #获取一个cookie对象
handler = urllib2.HTTPCookieProcessor(cookie)        #利用urllib2库的HTTPCookieProcessor对象来创建cookie处理器
opener = urllib2.build_opener(handler)                #装载cookie,通过handler来构建opener

'''
opener:当你获取一个URL你使用一个opener(一个urllib2.OpenerDirector的实例)。平时使用的默认opener就是urlopen,他是一个特殊的opener,
可以理解成opener的一个特殊实例，传入的参数仅仅是url，data，timeout。

然后丢到服务器上，因为v2ex每天早上8点签到时间重置，所以把crontab设置到八点十分。然后就等着收金币吧。O(∩_∩)O~~
