Laravel 5.5路线控制器[未找到页面]

尝试将“程序/类别”更改为程序.类别"

您要将“程序”前缀添加到类别资源路由。您可以按以下方式更改代码:

$router->resources([
    'programs'             => ProgramController::class,
]);



// to add programs prefix to categories routes
Route::group(['prefix' => 'programs'], function () use ($router) {
    $router->resource('categories', ProgramCategoryController::class);

    // here you can add more routes and all those routes will have 
    // "programs" prefix in there url
});

补充资源控制器

Route::resource; 否则 resource 方法可能无意中优先于您的补充路由:

Route::get('photos/popular', 'PhotoController@method');

Route::resource('photos', 'PhotoController');

$router->resources([
    'programs'             => ProgramController::class,
    'programs/categories'  => ProgramCategoryController::class,
]);

对此:

$router->resources([
    'programs/categories'  => ProgramCategoryController::class,
    'programs'             => ProgramController::class,
]);

crud 操作。
