DRF-限制不一致

Question

嗨，我在Django Rest框架中面临着节流机制的极端不一致。我有节气门10请求/sec的API端点，但是当我使用Apache Benchmark同时发送20个请求时，API应节气门10请求，而油门4，6>这是不一致的。有时，它甚至不会油门任何请求。

class StatusApiThrottle(CustomeRateThrottle):
    rate = '10/s'
    scope = 'status'

    def allow_request(self, request, view):  # independent throttle for GET request on view
        if request.method == "POST":
            return True
        return super().allow_request(request, view)

缓存配置

CACHES = {
"default": {
        "BACKEND": "django_redis.cache.RedisCache",
        "LOCATION": "redis://127.0.0.1:6379/1",
        "OPTIONS": {
            "CLIENT_CLASS": "django_redis.client.DefaultClient"
        },
        "KEY_PREFIX": "myapp"
    }
}

使用Gunicorn

gunicorn app --workers 2 --threads=2

使用Apache Benchmark进行测试

$ ab -n 20 -c 20 -v 1 http://127.0.0.1:8080/api/v1/access/842b1012-53ef-4e98-9a20-484e681c3789
