python - 如何在Redis中保存复杂的数据结构？

Question

我是Python新手。我在运行代码时遇到错误:

import redis

def redisSave(case, key, ob):
    dataBase = None
    if case == 'Product':
        dataBase = redis.Redis(db=0)
        dataBase.set(key, ob)
        dataBase.expire(key, time=600)
    else:
        pass

dictOb = {
    'price': '2000 $',
    'weight': '50 lb'
}
redisSave('Product', 'first', dictOb)

它说输入类型无效(redis.exceptions.DataError)

试试这个:

def redis_save(case, key, obj):
    data_base = None

    if case == 'Product':
        data_base = redis.Redis(db=0)

        if isinstance(obj, dict):
            data_base.hmset(key, obj)
            data_base.expire(key, time=600)

访问数据: data_base.hgetall('first')

结果:

{
    b'price': b'2000 $',
    b'weight': b'50 lb'
}
