Django Middleware records all requests and request execution times

class Loggingmiddleware (object):     def process_request (self, request):         = time.time ()    def  process_response (self, request, response):        = Time.time ()- request.start_time         = Request.get_full_path ()        info_logger.info ('request%s execute_time%f' % (path, execute_time))        return response

middleware_classes = (    'django.middleware.common.CommonMiddleware',     ' Mobile.middlewares.LoggingMiddleware ' ,)

1 middleware ensures that the process_request and Process_response methods do not have multithreading concurrency, so the request in 2 methods must be the same request

2 methods do not refer to global variables or variables in the current class, otherwise there will be problems in multithreaded concurrency or co-processes

3 Process_request is executed sequentially from top to bottom, process_response in turn

4 If the end of your urlconf has a backslash/, when the link does not have a backslash, commonmiddleware redirects the request to a URL with a backslash

5 There is a pit here, when the request is directed from Commonmiddleware, the process_request of all middleware behind it will not be executed, but the process_response of all middleware will be executed in reverse.

In this case, the Loggingmiddleware Process_response method above will be reported as abnormal, because there is no request.start_time

6 workaround, change the two middleware position, but this will record a request without a backslash (without a backslash request does not exist), there is a link all the requests are added backslashes, but for historical reasons

May sometimes be added to the whole.
