Php Symfony 2-命令容器的配置

我在app/config.yml示例中定义了：

module_my_module
   key: value1
   key2: value2

以及一个带有DependecyInjection Configuration.php的捆绑包：

<?php

namespace Modules\Bundle\MyModuleBundle\DependencyInjection;

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

class Configuration implements ConfigurationInterface
{
    public function getConfigTreeBuilder()
    {
        $treeBuilder = new TreeBuilder();
        $rootNode = $treeBuilder->root('module_configuration');
        $rootNode->children()
                ->scalarNode('key')->defaultValue('')->end()
                ->scalarNode('key2')->defaultValue('')->end()
            ->end()
            ;

        return $treeBuilder;
    }
}

Config.yml：

module_configuration
     key:  val

必须将参数注入

扩展

捆绑类定义中的容器中

在您的情况下，您必须具有类似于：

<?php

namespace Modules\Bundle\MyModuleBundle\DependencyInjection;


class MyModuleExtension 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('...');

        $container->setParameter('my_first_key', $config['key']);
        $container->setParameter('my_second_key', $config['key2']);

    }
}

---

希望此帮助

在

containerWareCommand

中，您可以通过

$this->getContainer（）->getParameter（“param_name”）

<?php

namespace Modules\Bundle\MyModuleBundle\DependencyInjection;


class MyModuleExtension 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('...');

        $container->setParameter('my_first_key', $config['key']);
        $container->setParameter('my_second_key', $config['key2']);

    }
}

class MyCommand extends ContainerAwareCommand
{

    protected function execute(InputInterface $input, OutputInterface $output)
    {
    $this->getContainer()->getParameter("my_first_key");
    }

}
