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但我总是有错误消息:没有可以加载“app”配置的扩展名“
我的文件位于: 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 /”中。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);
}
}
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:(
任何的想法 ?感谢。
答案 0 :(得分:9)
如果要加载自定义配置文件以使用Extension类处理它的参数(类似于Symfony包扩展但不创建包),最终“创建”并添加一个或更多的是“容器”(在编译之前),您可以在configureContainer
文件中包含的Kernel.php
方法中手动注册Extension类:
protected function configureContainer(ContainerBuilder $container, LoaderInterface $loader)
{
# to avoid the same error you need to put this line at the top if your file is stored under "$this->getProjectDir().'/config'" directory
$container->registerExtension(new YourAppExtensionClass());
#----- rest of the code
}
然后你可以像往常一样使用你的参数registering a Compiler Pass。
希望这有帮助。
