我正在使用Channels Redis进行websocket操作。但是,我想确切地查看它在Redis中节省了多少。怎么办?
这是我到目前为止所拥有的:
>>> import redis
>>> r = redis.Redis()
>>> r.keys()
['asgi::group:chat_hello', 'asgi::group:chat_lobby', 'asgi::group:chat_hi', 'iTunes+1068285837']
>>> r.get('asgi::group:chat_hello')
redis.exceptions.ResponseError: WRONGTYPE Operation against a key holding the wrong kind of value
答案 0 :(得分:1)
首先,检查相关密钥的类型:
>>> r.type('asgi::group:chat_hello')
'zset'
它是zet类型,或redis中的sorted set。要查看排序集的内容,可以执行以下操作:
# r.zrange(key, 0, -1) -- 0, 1 specifies the starting and ending index,
-- where 0 is the start and -1 is the end
>>> r.zrange('asgi::group:chat_newplace', 0, -1)
['specific.AUWRSlpx!NjGkQvODgPHx']
