尝试将外部身份验证与Laravel的身份验证相结合，我似乎无法使其正常工作

阅读并尝试了我在stackoverflow Custom user authentication base on the response of an API call中找到的这篇文章，基于这篇文章，我已经成功地将外部认证的用户信息放到Laravel的Auth系统中。

我的问题是当我登录并使用该凭据登录外部API时（假设我们从API成功获取用户信息）并重定向到另一个页面，Auth::user()似乎无法正常工作总是返回null值，看起来会话没有持久...

我还尝试创建自定义会话以将来自API的返回数据放入ApiUserProvider中，以便稍后在其他路由中访问它，但会话会丢失....

我希望有人可以帮助我，谢谢

PS：我正在使用Laravel 5.4

配置/ auth.php

'providers' => [

我认为这是因为我在登录时使用的是api路由，这就是为什么它未在auth会话中存储在信息中的原因，

我尝试在api路由中添加startsession中间件，但它可以正常工作，但我认为这是不对的，因为api路由必须是无状态的。
