Flask-session用法

app = Flask(__name__)
app.debug = True
app.secret_key = ‘xxxx‘

app.config[‘SESSION_TYPE‘] = ‘redis‘ # session类型为redis
app.config[‘SESSION_PERMANENT‘] = False # 如果设置为True，则关闭浏览器session就失效。
app.config[‘SESSION_USE_SIGNER‘] = False # 是否对发送到浏览器上session的cookie值进行加密
app.config[‘SESSION_KEY_PREFIX‘] = ‘session:‘ # 保存到session中的值的前缀
app.config[‘SESSION_REDIS‘] = redis.Redis(host=‘127.0.0.1‘, port=‘6379‘, password=‘123123‘) # 用于连接redis的配置
