交响乐2。没有能够加载配置的扩展。自定义配置块

Question

我在 symfony 2 中开始我的第一个项目。我使用 Symfony 2.6.6

我的AppKernel.php

<?php

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

class AppKernel extends Kernel
{
    public function registerBundles()
    {
        $bundles = array(
            new Symfony\Bundle\FrameworkBundle\FrameworkBundle(),
            new Symfony\Bundle\SecurityBundle\SecurityBundle(),
            new Symfony\Bundle\TwigBundle\TwigBundle(),
            new Symfony\Bundle\MonologBundle\MonologBundle(),
            new Symfony\Bundle\SwiftmailerBundle\SwiftmailerBundle(),
            new Symfony\Bundle\AsseticBundle\AsseticBundle(),
            new Doctrine\Bundle\DoctrineBundle\DoctrineBundle(),
            new Sensio\Bundle\FrameworkExtraBundle\SensioFrameworkExtraBundle(),
            new FOS\UserBundle\FOSUserBundle(),
            new AppBundle\AppBundle(),
        );

        if (in_array($this->getEnvironment(), array('dev', 'test'))) {
            $bundles[] = new Symfony\Bundle\DebugBundle\DebugBundle();
            $bundles[] = new Symfony\Bundle\WebProfilerBundle\WebProfilerBundle();
            $bundles[] = new Sensio\Bundle\DistributionBundle\SensioDistributionBundle();
            $bundles[] = new Doctrine\Bundle\FixturesBundle\DoctrineFixturesBundle();
            $bundles[] = new Sensio\Bundle\GeneratorBundle\SensioGeneratorBundle();
        }

        return $bundles;
    }

    public function registerContainerConfiguration(LoaderInterface $loader)
    {
        $loader->load($this->getRootDir().'/config/config_'.$this->getEnvironment().'.yml');
    }
}

还有我的src/AppBundle/DependencyInjection\AppExtension.php

<?php
namespace AppBundle\DependencyInjection;

use Symfony\Component\HttpKernel\DependencyInjection\Extension;
use Symfony\Component\DependencyInjection\ContainerBuilder;
use Symfony\Component\DependencyInjection\Loader\YamlFileLoader;
use Symfony\Component\Config\FileLocator;

class AppExtension extends Extension
{
    public function load(array $configs, ContainerBuilder $container)
    {
        $configuration = new Configuration();
        $config = $this->processConfiguration($configuration, $configs);

        $loader = new YamlFileLoader(
            $container,
            new FileLocator(__DIR__.'/../Resources/config')
        );
        $loader->load('services.yml');

    }
}

我的配置classsrc/AppBundle/DependencyInjection\Configuration.php

<?php

namespace AppBundle\DependencyInjection;

use Symfony\Component\Config\Definition\Builder\TreeBuilder;
use Symfony\Component\Config\Definition\Builder\ArrayNodeDefinition;
use Symfony\Component\Config\Definition\ConfigurationInterface;

class Configuration implements ConfigurationInterface
{
    /**
     * Generates the configuration tree.
     *
     * @return TreeBuilder
     */
    public function getConfigTreeBuilder()
    {
        $treeBuilder = new TreeBuilder();
        $rootNode = $treeBuilder->root('karmed');
        $rootNode->children()->scalarNode('var')->end();

        return $treeBuilder;
    }
}

和app/config/config.yml

的一部分

karmed:
  var: off

我不明白为什么我打电话给 app/console 时会收到这条消息？

  [Symfony\Component\Config\Exception\FileLoaderLoadException]    There is no extension able to load the configuration for "karmed" (in /home/vstas/data/work/karmed/app/config/config.yml). Looked for namespace "karmed", found "framework", "security", "twig", "monolog", "swiftmailer", "assetic", "doctrine", "sensio_framework_extra", "fos_user", "app", "debug", "web_profiler", "sensio_distribution" in /home/vstas/data/work/karmed/app/config/config.yml (which is being imported from "/home/vstas/data/work/karmed/app/config/config_dev.yml").

我尝试从目录 app/cache

中删除所有文件

我认为问题出在配置加载顺序上，因为当我尝试将 AppExtension 更改为

.....
class AppExtension extends Extension
{
    public function load(array $configs, ContainerBuilder $container)
    {
        print "exit";
        exit();
        $configuration = new Configuration();
.....

没有任何变化。但是当我从 config.yml 中删除我的部分变量时，我可以看到我的调试消息。

Answer 1

用于配置的不是根节点名称，而是扩展的 DI 别名。因为它是 AppExtension，所以它的别名是 app。使用 app: 配置它。

但是，AppBundle 并不意味着可以重复使用。它不应该使用自定义配置的东西。只需使用常量（最佳实践）或直接使用服务参数（推荐实践）。

Symfony2. There is no extension able to load the configuration. Custom configuration block
