Validation symfony2在配置中注入服务

validation symfony dependency-injection

Validation symfony2在配置中注入服务,validation,symfony,dependency-injection,Validation,Symfony,Dependency Injection,我需要根据特定的配置使用特定的验证器来验证JSON消息 我已经将验证器和约束定义为服务： services: validator.constraint.message.country_code: class: RenamedBundle\Validator\Constraints\CountryCode arguments: ... validator.constraint.message.price_comma: class:

我需要根据特定的配置使用特定的验证器来验证JSON消息

我已经将验证器和约束定义为服务：

services:
    validator.constraint.message.country_code:
        class: RenamedBundle\Validator\Constraints\CountryCode
        arguments: ...

    validator.constraint.message.price_comma:
        class: RenamedBundle\Validator\Constraints\PriceComma
        arguments: ...

    message.validator:
        class: RenamedBundle\Service\Validator\MessageValidatorService
        arguments: ['@validator']
        calls:
            - [addConstraint, ['@validator.constraint.message.country_code']]
            - [addConstraint, ['@validator.constraint.message.price_comma']]
在
DtoValidatorService
中，我使用约束列表调用
validate（）

问题。。。挑战在于，同一个JSON消息可能只需要验证列表中的几个验证器，这取决于消息属性，例如，对于波兰，我希望验证所有浮点值（在波兰，分隔符是“，”而不是“）。我试图通过
config.yml
来实现这一点


renamed:
    pritners:
        warehouse_wa:
            characteristic:
                country: 'pl'
                source: 'hq-pl'
            validators:
                - '@validator.constraint.message.country_code'
                - '@validator.constraint.message.price_comma'
        warehouse_ny:
            characteristic:
                country: 'us'
                source: 'hq-us'
            validators:
                - '@validator.constraint.message.country_code'


我添加了扩展：


class Configuration implements ConfigurationInterface
{
    /**
     * {@inheritDoc}
     *
     * @throws \RuntimeException
     */
    public function getConfigTreeBuilder()
    {
        $treeBuilder = new TreeBuilder();
        $rootNode = $treeBuilder->root('renamed');

        $rootNode
            ->children()
                ->arrayNode('printers')
                ->useAttributeAsKey('name')
                    ->prototype('array')
                        ->children()
                            ->arrayNode('characteristic')
                                    ->children()
                                        ->scalarNode('country')->end()
                                        ->scalarNode('source')->end()
                                    ->end()
                            ->end()
                        ->end()
                        ->children()
                            ->arrayNode('validators')
                                ->prototype('scalar')->end()
                            ->end()
                        ->end()
                    ->end()
                ->end()
            ->end();

        return $treeBuilder;
    }
}

class RenamedExtension extends Extension
{
    /**
     * {@inheritDoc}
     * @throws \Exception
     */
    public function load(array $configs, ContainerBuilder $container)
    {
        $configuration = new Configuration();
        $config = $this->processConfiguration($configuration, $configs);
        $container->setParameter('printers', $config['printers']);

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


此配置有效，但问题是当我将
'%printers%'
参数传递到服务中时，我收到了服务名称列表：


Array
(
    [0] => @validator.constraint.message.country_code
)


但当我通过约束时，我得到了对象


array(1) {
  [0] =>
  class RenamedBundle\Validator\Constraints\CountryCode#688 (5) {
    ...
  }
}


我现在死定了。如何参数化打印机配置并避免传递内联/硬代码验证程序类名。不允许在参数部分调用服务。在配置中调用它们为我提供了额外的控制和验证。
也许有人有更好的解决办法

编辑：
根据@Artur-Vesker的建议，我更改了扩展加载方法的实现


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

    $printers = [];
    foreach ($config['printers'] as $printerName => $printerConfig) {

        $constraints = [];
        foreach($printerConfig['valdiators'] as $constraintName) {
            $constraintName = ltrim($constraintName, '@');
            $constraints[] = new Reference($constraintName);
        }
        $printerConfig['valdiators'] = $constraints;

        $printers[$printerName] = $printerConfig;
    }

    $container->setParameter('printers', $printers);

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


正在尝试构建缓存，我得到：


Symfony\Component\DependencyInjection\Exception\InvalidArgumentException 
You cannot dump a container with parameters that contain references to other services 


在symfony world中，我的做法似乎是不允许的；]
 使用

仅在配置中设置ID：

并在您的扩展中使用引用创建参数


$validators = array_map(function($id) {
     return new Reference($id); 
}, $config['pritners.warehouse_wa.validators']);

$messageValidatorDefinition = new Definition('RenamedBundle\Service\Validator\MessageValidatorService', [new Reference('validator)]);

   foreach ($validators as $validator) {
      messageValidatorDefinition->addMethodCall('addConstraint', [$validator])
   } 



谢谢Artur Vesker，你的解决方案适合我。
我试图将
message.validator
保存在
services.yml
中（我希望有PHPStorm提示），并通过
$container->getDefinition（'message.validator'）
在扩展中获取它们，但这样
addMethodCall
就不起作用了。因此，任何尝试这种方式的人都不会成功，您必须按照Artur的建议创建服务动态性

我的完整代码：
-相同的
类配置实现了ConfigurationInterface

-相同的
config.yml

-从
services.yml

-在messageValidator中，我决定按打印机名称对约束进行分组

谢谢你的回复。现在我得到了
Symfony\Component\DependencyInjection\Exception\InvalidArgumentException您不能转储包含对其他服务引用的参数的容器
看起来不允许以这种方式传递服务。实际上，我必须创建单独的服务并在其中保留配置…哦，当然。我已经更新了我的答案。只需从services.yml中删除“message.validator”，它将在扩展中创建，并带有来自配置的约束。
