python与redis交互方法

1. 通过python向redis数据库中插入string类型的键

from redis import StrictRedis

#创建redis连接对象
sr = StrictRedis(host="localhost", port=6379, db=0)

#插入一个键为name，对应值为Bob
r = sr.set(name="name", value="Bob")

2. 通过python查询redis数据库中的某个string类型的键值

from redis import StrictRedis

#创建redis连接对象
sr = StrictRedis(host="localhost", port=6379, db=0)

#查询键为name的值
r = sr.get(name="name")

3 . 通过python删除redis数据库中的string类型的键

from redis import StrictRedis

#创建redis连接对象
sr = StrictRedis(host="localhost", port=6379, db=0)

#删除键名为name的键
r = sr.delete(name="name")

4. 通过python查询数据库中的全部键名

from redis import StrictRedis

#创建redis连接对象
sr = StrictRedis(host="localhost", port=6379, db=0)

res = sr.keys()
