可以再settings.py中配置有效时间，具体查官方文档

使用redis

pip install django-redis

        "OPTIONS": {
            "CLIENT_CLASS": "django_redis.client.DefaultClient",
        }
    }
}

接口访问评率设置

REST_FRAMEWORK = {
    # 加入如下两条
    'DEFAULT_THROTTLE_CLASSES': (
        'rest_framework.throttling.AnonRateThrottle',
        'rest_framework.throttling.UserRateThrottle'
    ),
    'DEFAULT_THROTTLE_RATES': {
        'anon': '2/minute',
        'user': '3/minute'
    }
}

views中

from rest_framework.throttling import UserRateThrottle,AnonRateThrottle


class GoodsListViewSet(CacheResponseMixin, mixins.ListModelMixin, viewsets.GenericViewSet):
    """
    商品列表页
    """
    # 加入此条
    throttle_classes = (UserRateThrottle, AnonRateThrottle)  # 接口访问频率限制
