Vazifa: Foydalanuvchilardan voqealar kelib tushadi, har biri tashqi manbada tekshirilishi kerak, ammo u darhol javob bermaydi.
VerificationService ni amalga oshiring:
- Foydalanuvchilardan voqealarni qabul qiladi
- Har birini tashqi xizmat bilan bog'lanib tekshiradi
- Agar javob PENDING bo'lsa, bu voqeani 5 soniyadan oldin qayta yubormaydi
- Maksimal 3 urinish, so'ngra voqea IDsi stdout ga FAILED holati bilan chiqariladi
- Muvaffaqiyatli ishlov berilgan voqealar stdout ga VERIFIED holati bilan chiqariladi
Tashqi bog'liqliklarning shablonlari va stub'lari allaqachon amalga oshirilgan:
1. VerificationStatus
2. Event
3. VerificationResult
4. IExternalSource
public enum VerificationStatus { OK, Pending, Error }
public record Event(string Id, string Payload);
public record VerificationResult(VerificationStatus Status, string? Message = null);
public interface IExternalSource
{
VerificationResult Verify(string eventId);
}
public class VerificationService
{
private readonly IExternalSource _externalSource;
private const int MaxAttempts = 3;
private static readonly TimeSpan RetryDelay = TimeSpan.FromSeconds(5);
public VerificationService(IExternalSource externalSource)
{
_externalSource = externalSource;
