req.session 使用 express

我有一个应用程序使用 cookie 和 node 和 express，我需要一些帮助来让它工作。我有登录功能，想将我的用户数据设置为 req.session.user，但是当我在另一个端点使用 req.session.user 时出现问题，它返回未定义但当控制台在同一端点记录 req.session.user 时它的工作。

所以我用邮递员登录并成功创建了一个cookie，但是当我尝试在浏览器中登录时，应用程序> cookies中没有任何变化。

想法是我想将我的用户信息和 jwt 令牌发送到登录（获取端点）并将数据存储到前端的 redux 状态，但我不想将用户登录数据保存在本地存储或会话存储中。我需要一个粗略的例子。

感谢所有帮助！提前致谢。
