Django使用redis缓存服务器

为了能在Django中使用redis，还需要安装redis for Django的插件。然后在Django的settings中配置了。现在连接和配置都已经完成了，接下来是一个简单的例子： 

from django.conf import  settings

from django.core.cache import cache

#read cache user id

def read_from_cache(self, user_name):

    key = 'user_id_of_'+user_name

    value = cache.get(key)

    if value == None:

        data = None

    else:

        data = json.loads(value)

    return data

#write cache user id

def write_to_cache(self, user_name):

    key = 'user_id_of_'+user_name

    cache.set(key, json.dumps(user_name), settings.NEVER_REDIS_TIMEOUT)
