.NET용 AWS SDK를 사용하여 Cross-Origin 리소스 공유(CORS) 활성화

버킷에 대한 cross-origin 리소스 공유(CORS)를 관리하려면 .NET용 AWS SDK를 사용하면 됩니다. CORS에 대한 자세한 내용은 CORS(Cross-Origin Resource Sharing) 단원을 참조하십시오.

다음 C# 코드는:

  • CORS 구성을 만들고 버킷에 구성 설정

  • 구성을 검색하고 규칙을 추가하여 구성 수정

  • 버킷에 수정된 구성 추가

  • 구성 삭제

실제 예제를 작성하여 테스트하는 방법에 대한 자세한 내용은Amazon S3 .NET 코드 예시 실행 단원을 참조하십시오.
