どのようにパッケージを使用せずにララベルのユーザーロールの独自のミドルウェアを作成するには?

~$ php artisan make:middleware RoleChecker

public function handle($request, Closure $next, $super_adminRole, $adminRole,  $sellerRole)
{
    $roles = Auth::check() ? Auth::user()->role->pluck('name')->toArray() : [];

    if (in_array($super_adminRole, $roles)) {
        return $next($request);
    } else if (in_array($adminRole, $roles)) {
        return $next($request);
    } else if (in_array($sellerRole, $roles)) {
        return $next($request);
    }

    return Redirect::route('home');
}

In the above code we assume that there are 4 types of users. Super Admin, Admin, Seller and Normal Auth User. We don't need to check the normal users in the middleware. So we are checking the remaining three Roles.

protected $routeMiddleware = [
    'roleChecker' => \App\Http\Middleware\RoleChecker::class,
];

Here we added the middleware

middleware(['roleChecker:super_admin,admin,seller']);
middleware(['roleChecker:super_admin,null,null']);
middleware(['roleChecker:null,admin,null']);
middleware(['roleChecker:null,null,seller']);

Use any of above code snippet to set middleware on any Route
