如何防止在config / services.yaml中为捆绑包定义别名？

Question

我有一个捆绑包，例如，我希望能够将其注入控制器中。 我希望用户要做的唯一一件事就是注册捆绑软件。 然后可以随意将服务注入到他们喜欢的任何地方：

namespace App\Bundles;

class MyService
{
    private $config;
    public function __construct(array $options)
    {
        $this->config= $options;
    }

    public function hello()
    {
        echo "Hello world";
    }
}

我试图在config / services.yaml中定义这一行：

App\Bundles\MyService: '@bundle_service'

这似乎可行，但是我不希望用户这样做。

这是我的配置类：

class Configuration implements ConfigurationInterface
{
    public function getConfigTreeBuilder()
    {
        $treeBuilder = new TreeBuilder("my_bundle");
        $treeBuilder->getRootNode()
            ->children()
                ->arrayNode('author')
                    ->children()
                        ->scalarNode("name")->end()
                    ->end()
                ->end()
            ->end();

        return $treeBuilder;
    }
}

还有my_bundle配置文件，到目前为止只是一个测试：

my_bundle:
  author:
    name: "Name"

我的捆绑扩展类：

class MyBundleExtension extends Extension
{
    public function load(array $configs, ContainerBuilder $container)
    {
        $loader = new YamlFileLoader(
            new FileLocator(__DIR__ .'/../Resources/config')
        );

        $loader->load('services.yaml');

       $configuration = new Configuration();
       $config = $this->processConfiguration($configuration, $configs);

        $container->setDefinition('bundle_service', new Definition(MyService::class, [$config]));
        $container->setAlias(MyService::class, 'bundle_service');
    }
}

我的捆绑课程：

class MyBundle extends Bundle
{
    public function getContainerExtension()
    {
        return new MyBundleExtension();
    }
}

我想念什么。 一切正常，除了我必须在config/services.yaml中定义这行App\\Bundles\\MyService: '@bundle_service' ，我不希望我的用户这样做。 在MyBundleExtension中，我提供了正确的定义：

        $container->setDefinition('bundle_service', new Definition(MyService::class, [$config]));
        $container->setAlias(MyService::class, 'bundle_service');

当我遗漏config/services.yaml代码时，出现此错误：

Cannot autowire service "App\Bundles\MyService": argument "$options" of method "__construct()" 

Answer 1

用变量创建服务

services:
    # ...

    App\Updates\SiteUpdateManager:
        arguments:
            $adminEmail: '%admin_email%'

要么

用以下方式构建您的服务

use Symfony\Component\DependencyInjection\ParameterBag\ParameterBagInterface;

class MessageGenerator
{
    private $params;

    public function __construct(ParameterBagInterface $params)
    {
        $this->params = $params;
    }

    public function someMethod()
    {
        $parameterValue = $this->params->get('my_bundle.author.name');
        // ...
    }
}

Answer 2

class MyBundleExtension extends Extension
{
        public function load(array $configs, ContainerBuilder $container)
        {
             $configuration = new Configuration();
             $config = $this->processConfiguration($configuration, $configs);

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

             $container->setParameter('my_bundle.author.name', $config['author']['name']);
        }
}

下一个

在config / services.yaml中声明服务

my_bundle.my_service.service:
    class: App\Bundles\MyService
    public: true
    arguments:
        - '%my_bundle.author.name%'
