django-rest-framework - 身份验证失败过多后如何锁定 IP 地址？

Question

在太多身份验证失败后，是否有锁定 IP 地址的常用方法？我不知道内置的节流将如何实现这一点，因为节流仅在身份验证和权限成功后才会启动。

Answer 1

谢谢汤姆。我使用以下代码对身份验证进行了子类化:

def authenticate(self, request):

    #
    # first check to see that IP address is not locked out
    # due to too many failed authentication requests.
    #
    auth_failure_key = 'LOGIN_FAILURES_AT_%s' % request.META.get('REMOTE_ADDR')

    auth_failures = cache.get(auth_failure_key) or 0

    # allow up to 3 failures per hour
    if auth_failures >= 3:
        raise exceptions.AuthenticationFailed('Locked out: too many authentication failures')

    try:
        return super(TokenAuthentication, self).authenticate(request)
    except exceptions.AuthenticationFailed as e:

        # update cache
        cache.set(auth_failure_key, auth_failures + 1, 3600)

        raise e
