如何使用Redis存储和检索字典

Question

# 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进行检索。例如，以下代码不起作用。

#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

您可以通过hmset（使用来设置多个键hmset）来做到这一点。

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'}
