Symfony2:根据域加载配置文件

Question

目前我们正在为德国经营一家网店.现在我们还希望在英国提供我们的产品,并拥有自己的域名.

根据域,它们是应加载的几个设置:

• Google Analytics ID
• 付款API秘密/密钥,......
• 货币
• 语言
• 管理员邮件
• 跟踪像素(FB)
• 和更多....

在之前的项目中,我们通过将此设置放在数据库的域表中来解决它.但我认为整个支付服务信息和密钥和和...它不是最好的解决方案.

您可以编写捆绑包Extension类来根据主机加载配置.

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的文件parameters_localhost.yml,它将自动加载.如果找不到该文件,parameters.yml将使用默认值.

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

希望这有帮助.
