在Redis執行後Django會話停止工作

Question

我已經使用此link實現了redis，並且在此會話之後必須存儲在redis instaed db中。配置完成後，重新啓動我的應用程序我正在爲我的會話收到嗨錯誤。

例如， 讓我們說IN函數A我聲明瞭一個會話，並且當我從瀏覽器訪問另一個鏈接並嘗試在視圖中獲取同一會話時，會話不在其中。甚至不存在會話密鑰。 request.session.keys（）爲空。

這裏是我的Redis的配置：

緩存服務器設置

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 

任何想法，爲什麼我收到鍵錯誤Django的會話。

似乎你只是簡單地啓用緩存會話做得非常好。除了django-redis之外，你爲什麼還使用django-redis-sessions，django-cachalot？

讓我們用最小的配置進行簡化，這對我很有用，僅使用django-redis。我下面their guide和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' 

就是這樣，通過請求查看和檢查request.session或測試，如果你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}
