Question

由于某些原因，我的symfony项目，屏幕底部出现的工具栏已经消失。我无法准确地回想起这发生的时间，或者我做了什么来触发它，但它出现并在一个阶段工作。它在我的config_dev.yml文件中启用为true。我的AppKernal.php文件看起来像这样

<?php

use Symfony\Component\DependencyInjection\ContainerBuilder;
use Symfony\Component\HttpKernel\Kernel;
use Symfony\Component\Config\Loader\LoaderInterface;

class AppKernel extends Kernel
{
public function registerBundles()
{
    $bundles = [
        new Symfony\Bundle\FrameworkBundle\FrameworkBundle(),
        new Symfony\Bundle\SecurityBundle\SecurityBundle(),
        new Symfony\Bundle\TwigBundle\TwigBundle(),
        new Symfony\Bundle\MonologBundle\MonologBundle(),
        new Symfony\Bundle\AsseticBundle\AsseticBundle(),
        new Symfony\Bundle\SwiftmailerBundle\SwiftmailerBundle(),
        new Doctrine\Bundle\DoctrineBundle\DoctrineBundle(),
        new Sensio\Bundle\FrameworkExtraBundle\SensioFrameworkExtraBundle(),
        new FOS\RestBundle\FOSRestBundle(),
        new FOS\CommentBundle\FOSCommentBundle(),
        new JMS\SerializerBundle\JMSSerializerBundle($this),
        new AppBundle\AppBundle(),
    ];

    if (in_array($this->getEnvironment(), ['dev', 'test'], true)) {
        $bundles[] = new Symfony\Bundle\DebugBundle\DebugBundle();
        $bundles[] = new Symfony\Bundle\WebProfilerBundle\WebProfilerBundle();
        $bundles[] = new Sensio\Bundle\DistributionBundle\SensioDistributionBundle();

        if ('dev' === $this->getEnvironment()) {
            $bundles[] = new Sensio\Bundle\GeneratorBundle\SensioGeneratorBundle();
            $bundles[] = new Symfony\Bundle\WebServerBundle\WebServerBundle();
        }
    }

    return $bundles;
}

public function getRootDir()
{
    return __DIR__;
}

public function getCacheDir()
{
    return dirname(__DIR__).'/var/cache/'.$this->getEnvironment();
}

public function getLogDir()
{
    return dirname(__DIR__).'/var/logs';
}

public function registerContainerConfiguration(LoaderInterface $loader)
{
    $loader->load(function (ContainerBuilder $container) {
        $container->setParameter('container.autowiring.strict_mode', true);
        $container->setParameter('container.dumper.inline_class_loader', true);

        $container->addObjectResource($this);
    });
    $loader->load($this->getRootDir().'/config/config_'.$this->getEnvironment().'.yml');
}
}

这是我的base.html.twig文件

        {% endfor %}
    </div>
{% endif %}
</nav>

当我检查页面源时，工具栏div id和class出现，当这是通过html验证器运行时它没有返回错误，所以我不知道问题可能是什么？如果您需要有关我的项目的更多信息以帮助回答我的问题，我很乐意提供帮助。谢谢

Answer 1

解决了它。我正在搞乱异常文件来创建我自己的个人404页面，在我这样做之后，页面必须摆脱工具栏。我解除了这些更改并发出了命令

 php bin/console cache:clear

瞧，酒吧又出现了：）

Answer 2

很多时候服务器localhost / vps配置设置不正确

添加

brainpopup.addEventListener("mouseover", function(){
  example.querySelector("img").style.display = "block";
})
brainpopup.addEventListener("click",function(){
example.querySelector("img").style.display="none";
})

Symfony工具栏没有显示？
