為方便以後的學習查詢，記載下來，嘻嘻。。

首先保證python已安裝redis

python -m pip install redis

redis共享資料步驟：

1. 匯入redis庫

2. 定義connection引數，包括server IP, redis埠號 ，redis passward

3. 示例化redis connection物件

4. 使用connection obj向redis server上傳message

5. 使用connection obj從redis server拉取message

redis使用示例：

# step 1: import the redis-py client package
import redis

# step 2: define our connection information for Redis
# Replaces with your configuration information
redis_host = "localhost"  #redis_host should be the server IP
redis_port = 6379
redis_password = ""


def hello_redis():
    """Example Hello Redis Program"""
    
    # step 3: create the Redis Connection object
    try:
    
        # The decode_repsonses flag here directs the client to convert the responses from Redis into Python strings
        # using the default encoding utf-8.  This is client specific.
        r = redis.StrictRedis(host=redis_host, port=redis_port, password=redis_password, decode_responses=True)
    
        # step 4: Set the hello message in Redis 
        r.set("msg:hello", "Hello Redis!!!")

        # step 5: Retrieve the hello message from Redis
        msg = r.get("msg:hello")
        print(msg)        
    
    except Exception as e:
        print(e)


if __name__ == '__main__':
    hello_redis()
 

python redis很好用有木有！！超讚！
