Message API reference

    Overview

    Samsung Cloud Platform 에서 제공하는 Queue Service는 메시지를 보내고 받고 그리고 삭제할 수 있습니다.
    본 가이드에서는 Queue Service의 API에 대한 설명 및 호출하는 방법을 제공합니다.

    Queue Service 호출 절차

    Queue Service API URL주소는 운영환경과 Region에 따라 변경되어야 합니다. 아래의 표에서 해당 운영환경과 Region 정보를 확인하십시오.

    API 호출하기

    AUTH PARAMS

    Header Description
    Scp-Accesskey      : 삼성 클라우드 플랫폼 포털에서 발급받은 Access Key
Scp-Signature      : 호출 API 요청을 Access Key와 매핑되는 Access Secret Key로 암호화한 서명. HMAC 암호화 알고리즘은 HmacSHA256 사용
Scp-Target         : Queue Service에 요청하는 행위. ScpQS.SendMessage, ScpQS.SendMessageBatch, ScpQS.ReceiveMessage, ScpQS.DeleteMessage, ScpQS.DeleteMessageBatch 중 하나
Scp-Timestamp      : 1970년 1월 1일 00:00:00 협정 세계시(UTC)부터의 경과 시간을 밀리초(Millisecond)로 정의합니다.
Scp-ClientType     : user-api 명시

    Signature 생성하기

    • 요청으로부터 서명할 문자열을 생성하고 Access, Secret Key로 HmacSHA256 알고리즘으로 암호화 후 Base64로 인코딩합니다.
    • 이 값을 Scp-Signature로 사용합니다.
    • 생성된 Signature는 15분간 유효합니다.1. 모든 서비스 > Application > Queue Service 메뉴를 클릭하세요. Queue Service의 Service Home 페이지로 이동합니다.
    Signature 생성 Sample Code (Java)
    public static String makeHmacSignature(String method,
                                       String url,
                                       String timestamp,
                                       String accessKey,
                                       String accessSecretKey,
                                       String clientType) {
 
    String body = method + url + timestamp + accessKey + clientType;

        mac.init(secretKeySpec);
        byte[] hmacSha256 = mac.doFinal(message);
        encodeBase64Str = Base64.getEncoder().encodeToString(hmacSha256);
    } catch (Exception e) {
        throw new RuntimeException("Failed to calculate hmac-sha256", e);
    }
