一般的OOP没有的东西，是个加工车间，类定义不是定局，还要进入这个车间。类似装饰器。
type 是最基本的车间

你可以把它想象成一颗洋葱：每个中间件都是包裹视图的一层“皮”，而视图就是洋葱心。如果request通过洋葱的各层(每层通过调用get_response传递request到下一层)，传向中心的视图，response会原路返回穿过各层。
如果某一次决定短路直接返回response(不再调用get_response)，余下的各层和视图将不会见到任何request和response。

和计算机网络的分层是一种设计
'^'在MULTILINE模式下，将匹配任意一行的行尾。也就是说，普通模式下，foo.$去搜索'foo1nfoo2n'只会找到'foo2'。但是，在MULTILINE模式，还能找到'foo1'。用一个$去搜索'foon'的话，会找到两个空的匹配：一个是最后的换行符，一个是字符串的结尾，演示：
>>> re.findall('(foo.$)', 'foo1nfoo2n') ['foo2'] >>> re.findall('(foo.$)', 'foo1nfoo2n', re.MULTILINE) ['foo1', 'foo2'] >>> re.findall('($)', 'foon') ['', '']
