php – Symfony2：根据域加载配置文件

捆绑扩展：

// src/AcmeBundle/DependencyInjection/AcmeExtension.php

<?php

namespace AcmeBundleDependencyInjection;

use SymfonyComponentConfigFileLocator;
use SymfonyComponentDependencyInjectionContainerBuilder;
use SymfonyComponentDependencyInjectionLoader;
use SymfonyComponentHttpKernelDependencyInjectionExtension;

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

        // Load parameters depending on current host
        $paramLoader = new LoaderYamlFileLoader($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 AcmeBundleDependencyInjection;

use SymfonyComponentConfigDefinitionBuilderTreeBuilder;
use SymfonyComponentConfigDefinitionConfigurationInterface;

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.
