如何让Symfony 6动态路由匹配含问号的URL？

我正在把旧网站迁移到Symfony框架，要求保留原有URL地址，因此将这些URL存入数据库并编写了自定义动态路由加载器DynamicRouteLoader。但部分URL包含问号，Symfony会将问号后的内容视为参数而忽略，导致路由匹配失败。例如访问http://web.local/page.asp?lang=sk时，会出现错误提示：No route found for "GET http://web.local/page.asp"。我目前想到的解决办法是通过.htaccess将问号替换为下划线。

以下是当前DynamicRouteLoader的代码：

namespace App\RouteLoader;

use Doctrine\ORM\EntityManagerInterface;
use RuntimeException;
use Symfony\Component\Config\Loader\Loader;
use Symfony\Component\Routing\Route;
use Symfony\Component\Routing\RouteCollection;
use App\Entity\Route as CustomRoute;

class DynamicRouteLoader extends Loader
{
    private EntityManagerInterface $entityManager;
    private bool $loaded = false;

    public function __construct(EntityManagerInterface $entityManager)
    {
        parent::__construct();
        $this->entityManager = $entityManager;
    }

    public function load($resource, $type = null): RouteCollection
    {
        if ($this->loaded) {
            throw new RuntimeException('Dynamic routes are already loaded.');
        }

        $routesCollection = new RouteCollection;

        /** @var CustomRoute[] $routes */
        $routes = $this->entityManager->getRepository(CustomRoute::class)->findAll();

        foreach ($routes as $route) {
            foreach (['cs', 'sk', 'en', 'de', 'ru'] as $lang) {
                $path = $route->getUrl($lang);
                $defaults = [
                    '_controller' => 'App\Controller\\' . $route->getController() . 'Controller::' . $route->getAction(),
                    '_locale' => $lang,
                ];
                $name = strtolower($route->getController()) . '_' . $route->getAction();
                if ($route->getParameters() !== null) {
                    $defaults['id'] = $route->getParameters();
                    $name .= '_' . $route->getParameters();
                }
                $name .= '_' . $lang;
                $routesCollection->add($name, new Route($path, $defaults));
            }
        }

        $this->loaded = true;

        return $routesCollection;
    }

    public function supports($resource, $type = null): bool
    {
        return $type === 'dynamic';
    }
}
