Token-Based Authentication Implementation for API Security

from rest_framework.authtoken.models import Token
from rest_framework.decorators import api_view, authentication_classes, permission_classes
from rest_framework.authentication import TokenAuthentication
from rest_framework.permissions import IsAuthenticated

@api_view(['GET'])
@authentication_classes([TokenAuthentication])
@permission_classes([IsAuthenticated])
def protected_endpoint(request):
    return Response({'message': 'Success'})

  1. TokenAuthentication requires the token to be sent in the request body

  2. The decorators specify that the endpoint requires a valid token in the Authorization header and the user must be authenticated

  3. TokenAuthentication is less secure than session-based authentication for APIs

  4. The endpoint can be accessed by any user without authentication if they know the URL

Show answer & explanation

Correct answer

The decorators specify that the endpoint requires a valid token in the Authorization header and the user must be authenticated

Explanation

TokenAuthentication uses tokens stored in the database to authenticate API requests. The @authentication_classes decorator specifies which authentication method to use, and @permission_classes ensures only authenticated users can access the endpoint.
