django 中间件process_exception 如果程序有异常就执行

def get(self, request, *args,**kwargs):    int(sss)    return  HttpResponse(‘login‘)

注意只要有捕获到异常就直接repon。好处可以直接返回500

class M1(MiddlewareMixin):    def process_request(self, request):        print(‘m1.process_request‘)

def process_view(self, request, callback, callback_args, callback_kwargs):        """        如果有返回值，则不在继续执行，直接到最后一个中间件的response        """        print(‘m1.process_view‘, callback)        # return HttpResponse(‘Process View返回值‘)    def process_response(self,request, response):        print(‘m1.prcess_response‘)        return response

def process_exception(self,request,exception):        print(‘m1.process_exception‘)

class M2(MiddlewareMixin):    def process_request(self, request):        print(‘m2.process_request‘)

def process_view(self, request, callback, callback_args, callback_kwargs):        """        如果有返回值，则不在继续执行，直接到最后一个中间件的response        """        print(‘m2.process_view‘, callback)        # return HttpResponse(‘Process View返回值‘)

def process_response(self,request, response):        print(‘m2.prcess_response‘)        return response

def process_exception(self,request,exception):        print(‘m2.process_exception‘)        return HttpResponse(‘500错误‘)

注意如果此时process_view有return  就直接到了reponse不会捕获错误
