python3读取Redis 报错WRONGTYPE Operation against a key holding the wrong kind of value

Redis 出现 WRONGTYPE Operation against a key holding the wrong kind of value

查询了网上很多资料，都说开启decode_responses=True就可解决，

from redis import StrictRedis,ConnectionPool

pool=ConnectionPool(host='192.168.1.214',port=6379,password='123456',db=0)
rs=StrictRedis(connection_pool=pool,decode_responses=True)

但我这里即使开启了读取到的依旧是字节类型。
所以干脆不用，直接在读到的字节后面加 decode()

ks=rs.keys()
for i in ks:
    ss=i.decode()
    print(ss)
