重定向 SF2 中的域和子域

Question

我遵循了 knpUniversity 的教程“如何在 symfony2 中处理动态子域”。路由子域有效，但是当我尝试访问 www.domain.com 时，我收到了如果子域不是则抛出的错误成立。如何解决这个问题？ 这是我的代码：

public function onKernelRequest(GetResponseEvent $getResponseEvent)
{
    $request = $getResponseEvent->getRequest();
    $host = $request->getHost();
    $base_host = $this->baseHost;
    $sub_domain = str_replace('.'.$base_host,'',$host);
    $site = $this->em->getRepository('AppBundle:Client')->findOneBy(['subDomain' => $sub_domain]);

    if(!$site){
        throw new NotFoundHttpException(sprintf(
            'Cannot find site for host "%s", subdomain "%s"  ',
            $host,
            $sub_domain
        ));
    }

    $siteManager = $this->siteManager;
    $siteManager->setCurrentSite($site);
}

Answer 1

我不知道这是否是最好的方法，但我已经成功了。

public function onKernelRequest(GetResponseEvent $getResponseEvent)
{
    $request = $getResponseEvent->getRequest();
    $host = $request->getHost();
    $base_host = $this->baseHost;
    $sub_domain = str_replace('.'.$base_host,'',$host);
    $site = $this->em->getRepository('AppBundle:Client')->findOneBy(['subDomain' => $sub_domain]);

    if(!$site && $base_host != $sub_domain){
        throw new NotFoundHttpException(sprintf(
            'Cannot find site for host "%s", subdomain "%s"  ',
            $host,
            $sub_domain
        ));
    }

    $siteManager = $this->siteManager;
    $siteManager->setCurrentSite($site);
}
