Hi All, I have written a custom Django middleware to do retries and catch exception if there is any connection related issues between two servers. Below is the code snippet. from requests.adapters import Retry, RetryError, HTTPAdapter, MaxRetryError, ConnectTimeoutError, ProtocolError, ResponseErrorfrom requests.sessions import Sessionfrom django.http import HttpResponseServerError
class RetryCal: def __init__(self, get_response): self.get_response = get_response @staticmethod def process_request(request): try: session = Session() retries = Retry(total=5, backoff_factor=2, status_forcelist=[500, 502, 503, 504]) session.mount('https://', HTTPAdapter(max_retries=retries)) request.retry_session = session except Exception as e: raise e def __call__(self, request): RetryCal.process_request(request) try: response = self.get_response(request) return response except (ProtocolError, OSError) as err: raise ConnectionError(err, request) except MaxRetryError as e: if isinstance(e.reson, ConnectTimeoutError): return HttpResponseServerError("Connection timeout error...") if isinstance(e.reson, ResponseError): raise RetryError(e, request=request) raise ConnectionError(e, request) Below is the placement of the custom middleware 'django.middleware.security.SecurityMiddleware','django.contrib.sessions.middleware.SessionMiddleware', # custom retry middleware.'integ.api_retry_custom_middleware.RetryCal', below this custom middleware I do have other default one's as well. The problem is I am not sure if this is working. I have an access token, In that I added some garbage characters and tried to hit my endpoint. I did see an exception as seen below Internal Server Error: /api/acct/[24/Jan/2024 14:23:39] "GET /api/acct/ HTTP/1.1" 500 5348 But I can see this error even if I comment out my custom middleware. My purpose is to create the custom middleware and if there is any API request from any Django App the request should go first through the custom middleware. That is my thought. But I am not sure if the middleware is working. Or maybe the placement if the custom middleware is not proper. I have been working with Django for a while now but written the custom middleware for the first time. Please suggest.
