依赖：

    port=6379)                           #服务器端口

app.config['SESSION_USE_SIGNER'] = True   #是否强制加盐，混淆session
app.config['SECRET_KEY'] = os.urandom(24)  #如果加盐，那么必须设置的安全码，盐
app.config['SESSION_PERMANENT'] = False  #sessons是否长期有效，false，则关闭浏览器，session失效
app.config['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。
