configuration - 如何使用symfony2访问 Controller 中的语义配置？

Question

我正在关注symfony 2的“如何公开捆绑软件的语义配置”官方手册。

我有我的configuration.php

namespace w9\UserBundle\DependencyInjection;

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

class Configuration implements ConfigurationInterface
{
    /**
     * {@inheritDoc}
     */
    public function getConfigTreeBuilder()
    {
        $treeBuilder = new TreeBuilder();
        $rootNode = $treeBuilder->root('w9_user');

        $rootNode
            ->children()
                ->scalarNode('logintext')->defaultValue('Zareejstruj się')->end()
            ->end()
        ;        

        return $treeBuilder;
    }
}

和w9UserExtension.php:

namespace w9\UserBundle\DependencyInjection;

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

class w9UserExtension 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');
    }
}

听起来很傻，但是我找不到方法，如何在 Controller 中访问logintext参数？

$logintext = $this->container->getParameter("w9_user.logintext");

不起作用。

我做错了什么？

Answer 1

在w9UserExtension.php行之后的processConfiguration中，只需添加

$container->setParameter('w9_user.logintext', $config['logintext']);
