我可以在编译器传递中访问语义配置吗？

Question

我有一个bundle的语义配置,需要在编译器传递期间为同一个bundle解释.

是否可以在不将其存储在中间容器变量中的情况下访问它？

Answer 1

是的,有点:

<?php

namespace Acme\DemoBundle\DependencyInjection;

use Symfony\Component\DependencyInjection\Compiler\CompilerPassInterface;
use Symfony\Component\DependencyInjection\ContainerBuilder;

class CompilerPass implements CompilerPassInterface
{
    public function process(ContainerBuilder $container)
    {
        $configs = $container->getExtensionConfig('acme_demo');
    }
}

从我可以看到的$configs是一组未合并的配置和默认值不包括(由配置TreeBuilder定义的值).

看到这里和这里

Answer 2

只是为了完整性@ Peter的答案:getExtensionConfig返回一个数组数组,应该使用相应的处理Configuration来访问默认值.

<?php

namespace Acme\DemoBundle\DependencyInjection;

use Symfony\Component\Config\Definition\ConfigurationInterface;
use Symfony\Component\Config\Definition\Processor;
use Symfony\Component\DependencyInjection\ContainerBuilder;
use Symfony\Component\DependencyInjection\Compiler\CompilerPassInterface;

class CompilerPass implements CompilerPassInterface
{
    public function process(ContainerBuilder $container)
    {
        $configs = $container->getExtensionConfig('acme_demo');
        $configuration = new Configuration();
        $config = $this->processConfiguration($configuration, $configs);

        /// You can safely work with $config now
    }

    private function processConfiguration(ConfigurationInterface $configuration, array $configs)
    {
        $processor = new Processor();

        return $processor->processConfiguration($configuration, $configs);
    }
}
