    $router->resource('users', UserController::class);
    ...
    
});

// User has permission `edit-post`、`create-post` and `delete-post` can access routes under group.
Route::group([
    'middleware' => 'admin.permission:check,edit-post,create-post,delete-post',

```php
use Encore\Admin\Auth\Permission;

class PostController extends Controller
{
    public function create()
    {
        // check permission, only the roles with permission `create-post` can visit this action
