我正在尝试按照此处提供的文档在我的应用程序中导入 yaml 配置文件http://symfony.com/doc/current/bundles/extension.html但我总是收到错误消息:
没有扩展能够加载“app”的配置
我的文件位于此处:config/packages/app.yaml并具有以下结构:
app:
list:
model1:
prop1: value1
prop2: value2
model2:
...
由于这是一个简单的应用程序,所有文件都在src/
. 所以我有src/DependencyInjection/AppExtension.php
<?php
namespace App\DependencyInjection;
use Symfony\Component\DependencyInjection\ContainerBuilder;
use Symfony\Component\Config\FileLocator;
use Symfony\Component\HttpKernel\DependencyInjection\Extension;
use Symfony\Component\DependencyInjection\Loader;
class AppExtension extends Extension
{
public function load(array $configs, ContainerBuilder $container)
{
$configuration = new Configuration();
$config = $this->processConfiguration($configuration, $configs);
}
}
和src/DependencyInjection/Configuration.php
<?php
namespace App\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('app');
// Node definition
$rootNode
->children()
->arrayNode('list')
->useAttributeAsKey('name')
->requiresAtLeastOneElement()
->prototype('array')
->children()
->requiresAtLeastOneElement()
->prototype('scalar')
->end()
->end()
->end()
->end()
->end();
return $treeBuilder;
}
}
我无法访问我的参数:(
知道吗?
