Throttling is a technique used to limit the number of requests a user can make to an API within a given time period. It is used to protect the API from being overloaded with requests, and to ensure that all users get a fair share of the resources. In this tutorial, we will learn how to implement throttling in Django REST framework.
Throttling is a technique used to limit the number of requests a user can make to an API within a given time period. It is used to protect the API from being overloaded with requests, and to ensure that all users get a fair share of the resources. Throttling is usually implemented by setting a limit on the number of requests a user can make in a given time period. If the user exceeds the limit, their requests will be blocked until the time period has elapsed.
Throttling is an important tool for protecting APIs from being overloaded with requests. It helps to ensure that all users get a fair share of the resources, and that the API is not overwhelmed by a single user making too many requests. Throttling also helps to prevent malicious users from making too many requests in an attempt to overwhelm the API.
Django REST framework provides a built-in throttling mechanism that can be used to limit the number of requests a user can make in a given time period. The throttling mechanism is implemented using the throttle decorator, which can be applied to any view or viewset.
In this example, we will limit the number of requests a user can make to the /api/v1/users endpoint to 10 requests per minute. To do this, we will use the throttle decorator and set the throttle_scope to user and the throttle_rate to 10/m.
from rest_framework.throttling import UserRateThrottle@api_view(['GET'])@throttle_scope('user')@throttle_rate('10/m')def get_users(request): # ...The throttle_scope parameter specifies the scope of the throttling. In this case, we are using the user scope, which means that the throttling will be applied to each individual user. The throttle_rate parameter specifies the rate at which the throttling will be applied. In this case, we are using the 10/m rate, which means that the user will be limited to 10 requests per minute.
In this tutorial, we have learned how to implement throttling in Django REST framework. We have seen how to use the throttle decorator to limit the number of requests a user can make in a given time period. Throttling is an important tool for protecting APIs from being overloaded with requests, and for ensuring that all users get a fair share of the resources.
