Python 与 redis 交互取出数据类型是 bytes 时,如何直接取出 str 数据类型

运行代码:(存 str 类型,得 bytes 类型,这是由于 Python3 与 redis 交互的驱动的问题,Python2 取出来的就是 str 类型的)

>>> from redis import *
>>> sr = StrictRedis(host='localhost', port=6379, db=0)
>>> sr
StrictRedis<ConnectionPool<Connection<host=localhost,port=6379,db=0>>>
>>> res = sr.set("name", "python")
>>> print(res)
True
>>> res1 = sr.get("name")
>>> print(res1)
b'python'

修改连接配置参数即可直接得到 str :(增加 decode_responses=True)

>>> sr1 = StrictRedis(host='localhost', port=6379, db=0, decode_responses=True)
>>> sr1
StrictRedis<ConnectionPool<Connection<host=localhost,port=6379,db=0>>>
>>> res2 = sr1.set("name3","python3")
>>> print(res2)
True
>>> res3 = sr1.get("name3")
>>> print(res3)
python3
>>>
