当重定向到不同页面时，Flask 登录为所有属性返回 False

如何解决当重定向到不同页面时，Flask 登录为所有属性返回 False

我在使用 Flask Login 时遇到问题，因为每次我导航到不同的页面时，flask login 似乎都没有跟踪会话。例如，在我登录的“/login”路径中，current_user_is_authenticated 返回 true 及其 id。但是，当我导航到“/reminders”路径以添加与用户关联的提醒时，我得到 current_user_is_authenticated False。我还尝试测试以查看 current_user_is_anonymous/is_active 是否仍然得到 False。如果我在“/reminders”和“/logout”路由中为 current_user_is 匿名、current_user_is_authenticated 和 current_user_is_active 设置为 false，我不知道问题是什么。
