3 redis与python交互

1、连接redis

import redis
sr = redis.StrictRedis(host="localhost", port=6379, db=0)
# 缩写
sr = redis.StrictRedis()

2、利用StrictRedis操作redis中string

import redis

sr = redis.StrictRedis(host="localhost", port=6379, db=0)
# 缩写
sr = redis.StrictRedis()

# 添加一个key = name, value = itheima
res = sr.set("name", "itheima")
print(res)  # True

# 获取key = name 的 value 值
res = sr.get("name")
print(res)  # b'itheima'

# 删除name对应的值 delect可以删除多个键值
res = sr.delete("name")
print(res)  # 1 返回值1表示删除成功1个

# 获取数据库中所有的键
res = sr.keys()
print(res)  # [b'timu', b'class']

3、利用redis存储session django存储session

利用redis存储session:
安装包：pip install django-redis-sessions
