Vis*_*nna 1 api validation symfony api-platform.com
我在 api 平台中使用带有自定义控制器的自定义端点作为用户实例。
class PayingMembershipForOthersController
{
private ValidatorInterface $validator;
public function __construct(ValidatorInterface $validator)
{
$this->validator = $validator;
}
public function __invoke(User $data)
{
$this->validator->validate($data);
try {
$paymentService->paymentMembership($data);
} catch(\Exception $e) {
throw $e
}
return $data;
}
}

如果找不到用户,我的 $userService 会抛出自定义异常,如下所示。
class XXXException extends \Exception
{
public function __construct(
$message = "user.notfound.message", // Translation file key.
$code = 0,
Throwable $previous = null
) {
parent::__construct($message, $code, $previous);
}
}

提前致谢..!!!

API 平台有两个有用的工具可以处理Exception:
第一个允许您从代码的任何位置引发异常。API 平台会捕获它,然后将其转换为漂亮的Response:
# config/packages/api_platform.yaml
api_platform:
# ...
exception_to_status:
App\Exception\MyException: 400
App\Exception\AnotherException: 500

下一个允许捕获抛出的异常并处理它。在您的情况下,有效负载是将异常消息翻译为适当的语言。在此示例中,我使用Symfony 翻译服务:
namespace App\EventSubscriber;
use Symfony\Component\EventDispatcher\EventSubscriberInterface;
use Symfony\Component\HttpKernel\Event\ExceptionEvent;
use Symfony\Component\HttpKernel\KernelEvents;
use Symfony\Contracts\Translation\TranslatorInterface;
class ExceptionSubscriber implements EventSubscriberInterface
{
private TranslatorInterface $translator;
public function __construct(TranslatorInterface $translator)
{
$this->translator = $translator;
}
public static function getSubscribedEvents()
{
return [
KernelEvents::EXCEPTION => ['translateException'],
];
}
public function translateException(ExceptionEvent $event): void
{
$currentException = $event->getThrowable();
$currentMessage = $currentException->getMessage();
$translatedMessage = $this->translator->trans($currentMessage);
$exceptionClass = get_class($currentException);
$translatedException = new $exceptionClass($translatedMessage);
$event->setThrowable($translatedException);
}
}

这样,每个未捕获的异常都将被转换,然后转换为 HTTP 错误响应。
