flask 引入redis 替换原生session存储session（flask-session）

import uuid, os
from redis import Redis

class BasicConfig(object):
    # SECRET_KEY = os.urandom(24)
    SECRET_KEY = str(uuid.uuid4())

class DevConfig(BasicConfig):
    DEBUG = True
    # Mysql 配置
    SQLALCHEMY_DATABASE_URI = ‘mysql+pymysql://root:123456@127.0.0.1/anec‘
    SQLALCHEMY_TRACK_MODIFICATIONS = ‘False‘
    SQLALCHEMY_POOL_SIZE = 5
    SQLALCHEMY_POOL_TIMEOUT = 15

    # redis 与 flask-session 配置
    SESSION_TYPE = ‘redis‘  # session存储格式为redis
    SESSION_REDIS = Redis(host=‘192.168.0.118‘, port=6379)
    SESSION_USE_SIGNER = True  # 是否强制加盐，混淆session
    SESSION_PERMANENT = False  # sessons是否长期有效，false，则关闭浏览器，session失效
    PERMANENT_SESSION_LIFETIME = 3600  # session长期有效，则设定session生命周期，整数秒，默认大概不到3小时。
