symfony - 没有扩展能够加载 “facebookbundle” symfony2的配置

我创建了自己的FacebookBundle，

我收到此错误:



该错误消息表示我在config.yml中获得了“facebookbundle”条目，该条目未被任何扩展名使用？

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']);
        }
    }
}

是错误吗？

最佳答案

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

src / FacebookBundle / DependencyInjection / 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;
    }
}
?>
