[PYTHON] I tried saving the DRF API request history with django-request

It's a story of using django-request in DRF.

What you can do

--Save API request history --Items that can be saved --Status code --Method --Path --Request date and time --Whether SSL --Whether it is ajax communication --IP address (** problem, see below **) --Referer --User agent --Language

Things impossible

--History of the contents of the request body such as POST parameters ――Since there is also a security point of view, saving POST parameters is risky, isn't it?

procedure

1 Install with pip etc.

pip install django-request

2 Add request to ʻINSTALLED_APPS`

3 Add request.middleware.RequestMiddleware to MIDDLEWARE

4 Migration execution

manage.py migrate

The API request is now stored in the request_request table.

Customize

Exclusion path

Even the request of django-admin will be saved, so I think it is better to exclude it I made it like this (health is a pass for health check)

REQUEST_IGNORE_PATHS = (
    r'^admin/', r'^docs/', r'^health$', r'\.ico$', r'^static/'
)

About IP address

Since the IP address uses REMOTE_ADDR, it cannot be obtained correctly if there is a load balancer. I made it like this with a bittersweet measure (Please tell me if there is a better way)

from request.middleware import RequestMiddleware

class XRequestMiddleware(RequestMiddleware):
    def process_response(self, request, response):
        # django-REMOTE in request_I have saved ADDR as IP, so I'm forced to HTTP_X_FORWARDED_Change to FOR
        http_x_forwarded_for_ip = request.META.get('HTTP_X_FORWARDED_FOR')
        remote_addr_ip = request.META.get('REMOTE_ADDR')
        if http_x_forwarded_for_ip:
            request.META['REMOTE_ADDR'] = http_x_forwarded_for_ip

        response = super().process_response(request, response)

        if http_x_forwarded_for_ip:
            request.META['REMOTE_ADDR'] = remote_addr_ip

        return response

By the way, in HTTP_X_FORWARDED_FOR, IP addresses may be entered separated by commas, so if you use REQUEST_IGNORE_IP, you should do as follows.

http_x_forwarded_for_ip = request.META.get('HTTP_X_FORWARDED_FOR').split(',')[0]

Impressions

It's easy to incorporate, and it's essential for data-driven. Another issue is backup when data is accumulated. However, I want you to update the IP address ...
