您可以编写捆绑软件 Extension class以根据主机加载配置.

捆绑扩展：

// src/AcmeBundle/DePEndencyInjection/AcmeExtension.PHP

<?PHP

namespace AcmeBundle\DependencyInjection;

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

class AcmeExtension extends Extension
{
    public function load(array $configs,ContainerBuilder $container)
    {
        $configuration = new Configuration();
        $config = $this->PRocessConfiguration($configuration,$configs);
        $rootdir = $container->getParameter('kernel.root_dir');

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

        // Load parameters depending on current host
        $paramLoader = new Loader\YamlFileLoader($container,new FileLocator($rootdir.'/config')); // Access the root config directory
        $parameters = sprintf('parameters_%s.yml',$container->getParameter('router.request_context.host'));

        if (!file_exists($rootdir.'/config/'.$parameters)) {
            $parameters = 'parameters.yml'; // Default
        }

        $paramLoader->load($parameters); 
    }
}

相应的捆绑配置：

// src/AcmeBundle/DependencyInjection/Configuration.PHP

<?PHP

namespace AcmeBundle\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('acme');

        return $treeBuilder;
    }
}

像这样,您可以创建一个名为parameters_localhost.yml的文件,它将自动加载.
如果找不到该文件,将使用默认的parameters.yml.

你可以根据你想要的每个参数应用这个逻辑(比如_locale用于你的翻译,我猜).

希望这有帮助.
