1   安装django-redis

pip3 install django-redis

2、配置settings.py

CACHES={
    "default":{
        "BACKEND":"django_redis.cache.RedisCache",
        "LOCATION":"redis://"+redis_host+":"+redis_port,            #redis主机地址和端口,数据在local_settings中
        "OPTIONS":{
            "CLIENT_CLASS":"django_redis.client.DefaultClient",
            "CONNECTION_POOL_KWARGS":{
                "max_connections":1000,
                "encoding":"utf-8"
            },
            "PASSWORD":redis_password                                #redis密码,数据在local_settings中
        }
    }
}

3、连接redis

conn=get_redis_connection('default')                  #这个default就是上一步中定义的redis
conn.set(phoneNum,code,ex=30)                         #设置键值
print(conn.get(phoneNum).decode('utf-8'))             #读取键值
