我正在遵循 5.2 上的 Laravel 教程，我正在使用 Laravel5.6.29。我做了两种类型的用户，一种是管理员，另一种是用户。我面临的问题是，当我以管理员身份登录时，它会将我重定向到它的仪表板。在导航栏上，它显示了用户名。但是在某些页面上，例如主页，博客页面，它仍然在导航栏中显示登录和注册链接，在某些页面上，例如帖子创建，编辑等，它显示登录用户的名称。如何解决此问题，以便@auth在所有页面上工作？以下是我的文件：

当我以管理员身份登录时，"登录和注册"链接将替换为视图(views>auth>{filesForLoggedInUsers}(中auth文件夹中文件中的我的姓名，但它在所有其他视图(包括欢迎，博客等(上显示登录和注册。请帮助我所缺少的。
你设置了什么默认配置/身份验证.php 你试过@auth('admin')吗？
您可以查看文档
指定管理员身份验证保护以显式检查管理员用户的身份验证。
