How can I implement a check for the number of requests in a certain amount of time in jango using middleware?

Question

Django

please tell me how to use middleware to return an error if there have been more than k requests from the same ip address in the last n seconds. ?

Answer 1

Yes, how - create middleware . In it, take the ip-address from the request header (for this, you first configure your web server so that it adds the desired header).
Next, execute code like this:

count = cache.get_or_set(f'ip:{ip_address}', 0, <нужное количество секунд>) 
count += 1
if count > <допустимое количество попыток>:
     raise Exception('Давай, - до свидания')
else:
     cache.set(f'ip:{ip_address}', count, <нужное количество секунд>)

Well, the most correct thing is to implement this logic on the side of the web server. He usually knows how to do it himself. And don't overload your middleware...
