php - 当 slug 不在数据库中时，Laravel route /{slug} 错误
问题描述
我在 web.php 中有一条路线
Route::get('/{slug_category}', 'WelcomeController@cdetail')->name('cdetail');
Route::get('/{slug_category}/{slug}', 'WelcomeController@detail')->name('detail');
我在数据库中的类别 slug 是action, movie
当我访问 /action 或 /movie 时，它的显示效果很好。但是当我访问不在数据库中的 /test 或 /something slug 之类的东西时，它会显示这样的错误
当我访问 /test 时显示“404 Page not found”之类的错误而不是上图的错误时如何解决？
这是我的代码

解决方案
这不是因为您的数据库中有参数（电影/动作），而是因为您的资源/视图中有刀片文件。
当您尝试使用/testor/something时，它会在您的视图中查找刀片文件为test.blade.phporsomething.blade.php并且失败会显示错误404 not found。
