Question

我想这样更改登录数据：$username = trim(strtolower($username));

为此，我创建了LoginSubscriber。登录前会调用onKernelRequest方法，但是如何在其中修改数据？也许还有其他方法可以做到？

class LoginSubscriber implements EventSubscriberInterface
{

    /**
     * @param \Symfony\Component\HttpKernel\Event\GetResponseEvent $event
     */
    public function onKernelRequest(GetResponseEvent $event)
    {
        dd($event->getRequest()->request->get('username'));
    }

    public static function getSubscribedEvents()
    {
        return [
            KernelEvents::REQUEST => ['onKernelRequest', 9]
        ];
    }
}

尝试更新您的LoginSubscriber：

class LoginSubscriber implements EventSubscriberInterface
{

    /**
     * @param \Symfony\Component\HttpKernel\Event\GetResponseEvent $event
     */
    public function onKernelRequest(GetResponseEvent $event)
    {
        $request = $event->getRequest();

        if ($request->request->has('username')) {
             $username = trim(strtolower($request->request->get('username')));
             // Update the username request value
             $request->request->set('username', $username);
        }
    }

    public static function getSubscribedEvents()
    {
        return [
            KernelEvents::REQUEST => ['onKernelRequest', 9]
        ];
    }
}

您是否尝试在services.yml配置文件中为列出的请求侦听器设置更高的优先级priority: 200？尝试执行bin /控制台debug：event-dispatcher命令以查看执行队列
