django中间件

中间件可以控制浏览器发送request请求到达view视图之前和response到达浏览器之前动作

from django.http import HttpResponse

EXCLUDE_IPS = [‘127.0.0.2‘]
def process_view(get_response):
    def middleware(request):
        ip = request.META[‘REMOTE_ADDR‘]
        if ip in EXCLUDE_IPS:
            return HttpResponse(‘拒绝访问‘)
        ‘‘‘request到view之前的动作‘‘‘
        response = get_response(request) #以response为分界线
        ‘‘‘response到达浏览器之前的动作‘‘‘
        return response
    return middleware
