如何使用redis存储和检索字典 [英] How to store and retrieve a dictionary with redis

问题描述

# I have the dictionary my_dict
my_dict = {
    'var1' : 5
    'var2' : 9
}
r = redis.StrictRedis()

我将如何存储 my_dict 并使用 redis 检索它.例如，以下代码不起作用.

How would I store my_dict and retrieve it with redis. For example, the following code does not work.

#Code that doesn't work
r.set('this_dict', my_dict)  # to store my_dict in this_dict
r.get('this_dict')  # to retrieve my_dict

推荐答案

可以通过hmset来实现(使用hmset可以设置多个键).

You can do it by hmset (multiple keys can be set using hmset).

hmset("RedisKey", dictionaryToSet)

import redis
conn = redis.Redis('localhost')

user = {"Name":"Pradeep", "Company":"SCTL", "Address":"Mumbai", "Location":"RCP"}

conn.hmset("pythonDict", user)

conn.hgetall("pythonDict")

{'Company': 'SCTL', 'Address': 'Mumbai', 'Location': 'RCP', 'Name': 'Pradeep'}
