Question

我创建了自己的FacebookBundle和

我收到了这个错误：

没有可以加载配置的扩展程序 “facebookbundle”（在/facebookx/app/config/config_dev.yml中）。找了命名空间“facebookbundle”，找到“框架”，“安全”，“树枝”， “monolog”，“swiftmailer”，“assetic”，“doctrine”， “sensio_framework_extra”，“jms_aop”，“jms_di_extra”， “jms_security_extra”，“d_facebook”，“d_user”，“d_security”， “web_profiler”，“sensio_distribution”

错误消息表示我在我的config.yml中有一个条目“facebookbundle”，任何扩展都没有使用它？

我的config.yml

facebookbundle:
    file:   %kernel.root_dir%/../src/FacebookBundle/Facebook/FacebookInit.php
    alias:  facebook
    app_id: xxx
    secret: xxx
    cookie: true
    permissions: [email, user_birthday, user_location, user_about_me]

我的DFacebookExtension

<?php

namespace D\FacebookBundle\DependencyInjection;

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

/**
 * This is the class that loads and manages your bundle configuration
 *
 * To learn more see {@link http://symfony.com/doc/current/cookbook/bundles/extension.html}
 */
class DFacebookExtension extends Extension
{
    /**
     * {@inheritDoc}
     */
    public function load(array $configs, ContainerBuilder $container)
    {
        $configuration = new Configuration();
        $config = $this->processConfiguration($configuration, $configs);

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

        foreach (array('app_id', 'secret', 'cookie', 'permissions') as $attribute) {
            $container->setParameter('facebookbundle.'.$attribute, $config[$attribute]);
        }

        if (isset($config['file']) && $container->hasDefinition('acebookbundle.api')) {
            $facebookApi = $container->getDefinition('facebookbundle.api');
            $facebookApi->setFile($config['file']);
        }
    }
}

是错误的？

Answer 1

另外，请记住配置文件的根密钥必须是Bundle名称的标准化形式。

这是我曾经多次遇到的事情，如果你不了解它，那就很难解决。

示例：如果调用bundle MyFirstAwesomeBundle，则文件中的根密钥必须为my_first_awesome。所以camel-case被转换为snake-case，“bundle”这个词被忽略或被删除。

因此，只需让文件中的根密钥与Configuration::getConfigTreeBuilder()中指定的值完全匹配即可。

如果您不遵守此规则，则会收到There is no extension able to load the configuration错误。

我希望这将有助于下一个绝望的灵魂谁最终在这个页面...

为了接受自定义配置参数，您必须使用捆绑包中的Configuration.php类来定义捆绑包配置。

<强>的src / FacebookBundle / DependencyInjection /的configuration.php：

<?php
namespace FacebookBundle\DependencyInjection;

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

/**
 * This is the class that validates and merges configuration from your app/config files
 *
 * To learn more see {@link http://symfony.com/doc/current/cookbook/bundles/extension.html#cookbook-bundles-extension-config-class}
 */
class Configuration implements ConfigurationInterface
{
    public function getConfigTreeBuilder()
    {
        $treeBuilder = new TreeBuilder();
        $rootNode = $treeBuilder->root('facebookbundle');

        $rootNode
            ->children()
                ->scalarNode('file')->defaultValue('')->end()
                ->scalarNode('alias')->defaultValue('')->end()
                ->scalarNode('app_id')->defaultValue('')->end()
                ->scalarNode('secret')->defaultValue('')->end()
                ->booleanNode('cookie')->defaultTrue()->end()
                ->arrayNode('permissions')
                    ->canBeUnset()->prototype('scalar')->end()->end()
            ->end()
            ;

        return $treeBuilder;
    }
}
?>

当您忘记在app / AppKernel.php中启动捆绑包时会发生这种情况：

<?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\DoctrineBundle\DoctrineBundle(),
              new Symfony\Bundle\AsseticBundle\AsseticBundle(),
              new Sensio\Bundle\FrameworkExtraBundle\SensioFrameworkExtraBundle(),
              new JMS\SecurityExtraBundle\JMSSecurityExtraBundle(),
              //...
              new D\FacebookBundle\DFacebookBundle(),
              //...
      );

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

      return $bundles;
   }

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

}

此错误也可能是由配置根目录中缺少或无效的services密钥引起的。看起来应该是这样的：

services:
    foo_bar.baz:
        class: Foo\BarBundle\Service\BazService

没有扩展程序可以加载“facebookbundle”symfony2的配置
