我正在关注5.2上的Laravel教程，而我正在使用Laravel 5.6.29。我有两种类型的用户，一种是Admin，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。并在导航栏上显示用户名。但是在某些页面（例如主页，博客页面）上，它仍然在导航栏中显示“登录和注册”链接，在某些页面上，例如在帖子创建，编辑等中，它仍显示登录用户的名称。如何解决此问题，以便@auth在所有页面上都能正常工作？以下是我的文件：

当我以管理员身份登录时，“登录和注册”链接被替换为视图（视图> auth> {filesForLoggedInUsers}）的auth文件夹中文件中的名称，但在所有其他视图（包括“欢迎”，“博客等。请帮助我所缺少的内容。
答案 0 :(得分：0)
您设置了什么默认config / auth.php
您尝试过@auth('admin')吗？
您可以检查docs

指定管理员身份验证保护程序以显式检查管理员用户的身份验证。
@auth('admin')
