django+redis实现底层的缓存api

Posted 2021-01-11 是张不是章啊

1.设置缓存

 这里使用redis作为缓存的数据库

CACHES = {

    "default": {
        "BACKEND": "django_redis.cache.RedisCache",
        "LOCATION": "redis://192.168.10.97:6379/1",
        "OPTIONS": {
            "CLIENT_CLASS": "django_redis.client.DefaultClient",
        }
    },
}

将数据库查询到到的queryset对象序列化后保存

....

print pickle.dumps(results)
cache.set(key,pickle.dumps(results),60*2)
.....

获取缓存到redis中的数据,将数据序列化输出
...
ai_news_list = cache.get("ai_news_%s" % username,None)
refersh_ai_news = pickle.loads(ai_news_list)[nums:nums+20]
...
