Python 之操作redis

一、示例代码

import redis

pool = redis.ConnectionPool(host='127.0.0.1', port=6379, password="", max_connections=10)
redis_obj = redis.Redis(connection_pool=pool, decode_responses=True)

# 操作字符串
redis_obj.set(name="password", value="123456", ex=6)
print(redis_obj.get("password"))

redis_obj.setex("username", 5, "Yang")
print(redis_obj.get("username"))

# 操作列表
redis_obj.delete("database")
redis_obj.lpush("database", "sql", "mysql", "mygodb")
redis_obj.linsert("database", "before", "mysql", "redis")

print(redis_obj.lrange("database", 0, -1))

# 操作hash散列值
redis_obj.hset("user", "username", "Yang")
print(redis_obj.hget("user", "username"))

# 一次设置多个
user = {
    "username": "Yang",
    "password": "123456",
}
redis_obj.hmset("user", user)
# 获取所有，返回字典
print(redis_obj.hgetall("user"))

#操作集合
redis_obj.sadd("color", "red", "blue", "yellow")
print(redis_obj.smembers("color"))

# 删除red
redis_obj.srem("color", "red")
print(redis_obj.smembers("color"))
