django-中间件

Posted 2020-10-15 forjie

1,首先要写上中间件的原始类.

class MiddlewareMixin(object):
    def __init__(self, get_response=None):
        self.get_response = get_response
        super(MiddlewareMixin, self).__init__()

    def __call__(self, request):
        response = None
        if hasattr(self, ‘process_request‘):
            response = self.process_request(request)
        if not response:
            response = self.get_response(request)
        if hasattr(self, ‘process_response‘):
            response = self.process_response(request, response)
        return response

2,继承原始类,增加自己所需要的功能

例如:让有session的对象可以跳过登录功能
