Redang实施后，Django会话停止工作

我已经使用此link实现了redis，并且在此会话之后必须存储在db的redis instaed中 . 配置后重新启动我的应用程序 . 我的会话收到了嘿错误 .

例如，让我说IN函数 A 我宣布了一个会话，当我从浏览器访问另一个链接并尝试获取相同的会话时，会话已经消失了 . 甚至没有会话密钥存在 . request.session.keys（）是空白的 .

这是我的redis配置：

缓存服务器设置

REDIS_PROT = "redis://"
REDIS_HOST = "127.0.0.1"
REDIS_PORT = 6379
REDIS_DB = 0

REDIS_CACHE_SERVER = REDIS_PROT + REDIS_HOST + ":" + str(REDIS_PORT) + "/" + str(REDIS_DB)
REDIS_CACHEALOT_SERVER = REDIS_PROT + REDIS_HOST + ":" + str(REDIS_PORT) + "/" + str(REDIS_DB + 3)

DJANGO_REDIS_IGNORE_EXCEPTIONS = True

CACHES = {
    "default": {
        "BACKEND": "django_redis.cache.RedisCache",
        "LOCATION": REDIS_CACHE_SERVER,
        "OPTIONS": {
            "PARSER_CLASS": "redis.connection.HiredisParser",
            "CLIENT_CLASS": "django_redis.client.DefaultClient",
            "COMPRESS_MIN_LEN": 10,
            "SOCKET_CONNECT_TIMEOUT": 5,  # in seconds
            "SOCKET_TIMEOUT": 5,  # in seconds
        }
    },
    "cachealot": {
        "BACKEND": "django_redis.cache.RedisCache",
        "LOCATION": REDIS_CACHEALOT_SERVER,
        "OPTIONS": {
            "PARSER_CLASS": "redis.connection.HiredisParser",
            "CLIENT_CLASS": "django_redis.client.DefaultClient",
            "COMPRESS_MIN_LEN": 10,
            "SOCKET_CONNECT_TIMEOUT": 5,  # in seconds
            "SOCKET_TIMEOUT": 5,  # in seconds
        }
    }
}

# CacheALot service settings 

CACHALOT_ENABLED = True
CACHALOT_CACHE   = 'cachealot'

# Django Redis Session App Configuration 

SESSION_REDIS_HOST = REDIS_HOST
SESSION_REDIS_PORT = REDIS_PORT
SESSION_REDIS_DB = REDIS_DB + 4
#SESSION_REDIS_PASSWORD = 'password'
SESSION_REDIS_PREFIX = 'session'

SESSION_ENGINE = 'redis_sessions.session'
# If you prefer domain socket connection, you can just add this line instead of SESSION_REDIS_HOST and SESSION_REDIS_PORT.
#SESSION_REDIS_UNIX_DOMAIN_SOCKET_PATH = '/var/run/redis/redis.sock'

# Celery Configurations
REDIS_CELERY_BROKER_SERVER =  REDIS_PROT + REDIS_HOST + ":" + str(REDIS_PORT) + "/" + str(REDIS_DB + 1)
REDIS_CELERY_RESULT_SERVER = REDIS_PROT + REDIS_HOST + ":" + str(REDIS_PORT) + "/" + str(REDIS_DB + 2)

BROKER_URL = REDIS_CELERY_BROKER_SERVER
CELERY_RESULT_BACKEND = REDIS_CELERY_RESULT_SERVER
CELERY_ALWAYS_EAGER=False

知道我为什么会得到django会话的关键错误 .

python django session redis

    对于简单地启用缓存会话，您似乎做得非常多 . 除了django-redis之外，你为什么还使用django-redis-sessions，django-cachalot？

    让我们使用最小配置进行简化，这对我来说很有用，仅使用django-redis . 我正在关注their guide，Django's documentation on setting up sessions和using cached sessions：

    CACHES = {
    "default": {
        "BACKEND": "django_redis.cache.RedisCache",
        "LOCATION": "redis://127.0.0.1:6379/1",
        "OPTIONS": {
            "CLIENT_CLASS": "django_redis.client.DefaultClient",
        }
    }
}
SESSION_ENGINE = 'django.contrib.sessions.backends.cache'

    就是这样，通过请求视图并检查 request.session 来测试它，或者，如果你是outside of request, using your session store：

    >>> from django.contrib.sessions.backends.cache import SessionStore
>>> s = SessionStore(session_key='ff882814010ccbc3c870523934fee5a2')
>>> s.save()
>>> s.session_key
'ff882814010ccbc3c870523934fee5a2'
>>> s.session_data
'KGRwMQpTJ19hdXRoX3VzZXJfaWQnCnAyCkkxCnMuMTExY2ZjODI2Yj...'
>>> s.get_decoded()
{'user_id': 42}
