컬렉션 설명

모음을 설명하려면(SDK)

1. 아직 설정하지 않았다면 다음과 같이 하세요.

   1. AmazonRekognitionFullAccess 권한이 있는 사용자를 생성하거나 업데이트합니다. 자세한 정보는 1단계: AWS 계정 설정 및 사용자 생성을 참조하세요.

   2. 및 AWS SDK를 설치 AWS CLI 및 구성합니다. 자세한 정보는 2단계: AWS CLI 및 AWS SDK 설정을 참조하세요.

2. 다음 예제를 사용하여 DescribeCollection 작업을 호출합니다.

   Java

   이 예제는 모음을 설명합니다.

   collectionId의 값을 원하는 모음의 ID로 변경합니다.

   AWS CLI

   이 AWS CLI 명령은 describe-collection CLI 작업에 대한 JSON 출력을 표시합니다. collection-id의 값을 원하는 모음의 ID로 변경합니다. Rekognition 세션을 생성하는 라인에서 profile_name의 값을 개발자 프로필의 이름으로 대체합니다.

   aws rekognition describe-collection --collection-id collection-name --profile profile-name
