django - Cache.get() 不返回任何内容

Question

我的缓存设置，

CACHES = {
"default": {
    "BACKEND": "util.redis.ExtendedCache",
    "LOCATION": "redis://%s:%i/1" % (REDIS_HOST, REDIS_PORT),
    "TIMEOUT": 7 * 24 * 60 * 60,  # One week in seconds
    "OPTIONS": {
        "SOCKET_TIMEOUT": 1,
        "CLIENT_CLASS": "util.redis.ExtendedClient",
        "CONNECTION_POOL_KWARGS": {"max_connections": 1},
        "SERIALIZER": "util.redis.FailsafePickleSerializer",
    },
},

}

当我在视图函数中执行以下操作时，

from django.core.cache import cache
cache.set(key, value)

当我在 shell 中查询相同的内容时，它没有返回任何内容，

cache.get(key) # returns nothing!
