Symfony服务,tagged_locator可以在yaml中使用配置,但不能在php中使用
我在服务配置中使用带标签的定位器 一切都与yaml配置一起工作。 但是当我在php中进行配置时,它就不再工作了。 “我的服务”的参数未填充 (0提供的服务) 配置YamlSymfony服务,tagged_locator可以在yaml中使用配置,但不能在php中使用,php,symfony,dependency-injection,symfony5,Php,Symfony,Dependency Injection,Symfony5,我在服务配置中使用带标签的定位器 一切都与yaml配置一起工作。 但是当我在php中进行配置时,它就不再工作了。 “我的服务”的参数未填充 (0提供的服务) 配置Yaml services: # default configuration for services in *this* file _defaults: autowire: true # Automatically injects dependencies in your services.

我的服务
$Criterian包含实现Criterioninterface的服务列表
class PostVoter extends Voter
{
private $criteria;
public function __construct(ServiceLocator $criteria)
{
$this->criteria = $criteria;
}
protected function supports(string $attribute, $subject)
{
dump($this->criteria->getProvidedServices()); //empty array in php config
return $subject instanceof Entry && $this->criteria->has($attribute);
}
}
class CanEdit implements CriterionInterface
{
public function handle(Entry $post, User $user): bool
{
return $user === $post->getOwner();
}
}
转储($this->criterias->getProviderServices())//php配置中的空数组
示例类使用此接口
class CanEdit implements CriterionInterface
{
public function handle(Entry $post, User $user): bool
{
return $user === $post->getOwner();
}
}
我的内核类,这是创建新sf应用程序时的原始类
class Kernel extends BaseKernel
{
use MicroKernelTrait;
protected function configureContainer(ContainerConfigurator $container): void
{
$container->import('../config/{packages}/*.yaml');
$container->import('../config/{packages}/'.$this->environment.'/*.yaml');
if (is_file(\dirname(__DIR__).'/config/services.yaml')) {
$container->import('../config/{services}.yaml');
$container->import('../config/{services}_'.$this->environment.'.yaml');
} elseif (is_file($path = \dirname(__DIR__).'/config/services.php')) {
(require $path)($container->withPath($path), $this);
}
}
protected function configureRoutes(RoutingConfigurator $routes): void
{
$routes->import('../config/{routes}/'.$this->environment.'/*.yaml');
$routes->import('../config/{routes}/*.yaml');
if (is_file(\dirname(__DIR__).'/config/routes.yaml')) {
$routes->import('../config/{routes}.yaml');
} elseif (is_file($path = \dirname(__DIR__).'/config/routes.php')) {
(require $path)($routes->withPath($path), $this);
}
}
}
感谢您的帮助感谢尼古拉斯·格雷卡斯纠正了我的错误: 配置程序是不可变的:您需要存储并使用调用defaults()和instanceof()的返回值:
必须在基于路径的服务发现(首次调用load())之前配置Instanceof conditionalsNo I remove services.yaml。当我切换文件时,使用的是yaml而不是php文件
