Flask 谷歌表单认证每隔几个小时左右就会过期一次

我目前正在使用在web服务器上连续访问Google Sheets文档

它托管在Flask web服务器（ApacheWSGi）上，因此与Google的连接必须是连续的、持续的身份验证

我遇到了一个问题，几个小时后，我需要重新生成book对象（重新验证），否则我会遇到这个问题（请参见下文）

下面是我为解决这个问题所做的努力，但我仍然遇到同样的问题，我想知道你是否有任何想法

共有5-6个不同的工作表，我正在创建一个类，该类使用不同的方法来访问每个工作表（都是从Access继承的）

几小时后（4-24小时之间的任何时间），我将得到以下错误：

Traceback (most recent call last):

     "status": "UNAUTHENTICATED"
   }
 }

几乎每次只要重新启动服务器就可以解决这个问题

重新生成book对象似乎无法解决问题，我已检查过该书的

id

是否每40分钟更改一次。

如果我理解正确，在我的使用中，我会按住

gc

并调用

book=gc。需要数据时按键打开（SHEET\u key）

基本上，不是将

book

保存为全局变量，而是保存

gc

，以便保留先前经过身份验证的会话并用于进一步的请求
