python 读取各种类型的redis值

本以为这是一件再简单不过的事情

>>> import redis
>>> r = redis.Redis(host='localhost', port=6379, db=0)
>>> r.set('foo', 'bar')
True
>>> r.get('foo')
'bar'

后来发现,这只能取到 String 类型 的值, 对于 list , set, zset, 以及 hash 类型需要采用各自的方法:

import redis
redis = redis.Redis(host='localhost', port=6379, db=0)
redis.set('foo', 'bar')
keys = redis.keys()

for key in keys:
    type = redis.type(key)
    if type == b'string':
        vals = redis.get(key)
    elif type == b'list':
        vals = redis.lrange(key, 0, -1)
        # print(vals)
    elif type == b'set':
        vals = redis.smembers(key);
    elif type == b'zset':
        vals = redis.zrange(key, 0, -1)
    elif type == b"hash":
        vals = redis.hgetall(key)
    else:
        print(type, key)
    print(vals)
