Python 使用 Redis

import redis
import warnings

warnings.filterwarnings('ignore')


# 默认连接到地址 127.0.0.1 端口 6379
# client = redis.StrictRedis()


# 显式指定需要连接的地址，可设置 password
client = redis.StrictRedis(host="127.0.0.1", port=6379, db=0)
print(client)


# 简单的 GET / SET
client.set("firstKey", "testString")
print(client.get("firstKey"))


# HSET 支持将字典作为参数存储，HGETALL 的返回值也是字典
client.hmset("testDict", {"name": "Tom", "species": "Cat"})
animal = client.hgetall("testDict")
print(animal)
print(animal[b"name"])


# 事务
transaction = client.pipeline()
transaction.set("testKey1", "aaa")
transaction.get("testKey1")
result = transaction.execute()
print(result)


# 管道，相比于事务只需要在创建时加上参数 transaction=False
pipeline = client.pipeline(transaction=False)
pipeline.set("testKey2", "bbb")
pipeline.get("testKey2")
result = pipeline.execute()
print(result)


# 事务和管道支持链式调用
result = client.pipeline(transaction=False).set("testKey3", "ccc").get("testKey3").execute()
print(result)
