python3存入redis是bytes

在python3 中使用redis存储数据，存进去的是bytes

>>> import redis
>>> import time
>>> import json

>>> pool = redis.ConnectionPool(host=‘localhost‘, port=6379)
>>> redis_obj = redis.Redis(connection_pool=pool)

>>> redis_obj.set(‘key2‘,str_data)
True
>>> redis_obj.get(‘key2‘)
b‘hello‘
>>> redis_obj.rpush(‘my_test_list_key2‘,json.dumps([{‘k1‘:‘v1‘},time.time()]))
1
>>> get_data_from_redis_key = redis_obj.lrange(‘my_test_list_key2‘,-1,-1)[0]
>>> type(get_data_from_redis_key)
<class ‘bytes‘>
