토큰 받기
API 요청을 테스트하기 위한 액세스 토큰을 생성하려는 경우 이샘플 앱을 사용할 수있습니다.
토큰은 Brightcove OAuth API에서 얻습니다. 액세스 토큰을 얻으려면 먼저 액세스하려는 API 및 작업과 관련된 클라이언트 자격 증명 (클라이언트 ID 및 클라이언트 암호)을 얻어야합니다. 클라이언트 자격 증명을 가져오려면 API 자격 증명관리를 참조하십시오 .
자격 증명이 있으면 다음을POST요청하여 액세스 토큰을 얻을 수 있습니다.
https://oauth.brightcove.com/v4/access_token
이 호출과 함께 다음 헤더를 전달해야합니다.
Content-Type: application/x-www-form-urlencodedAuthorization: Basic {client_id}:{client_secret}
전체{client_id}:{client_secret}문자열은 Base64로 인코딩되어야 합니다. --user자격 증명으로 전달하면 curl은 문자열을 자동으로 Base64로 인코딩합니다. 다른 언어에서는 Base64 인코딩을 직접 처리해야 합니다.
또한 다음 키/값 쌍을 요청 본문 또는 URL 매개 변수로 보내야 합니다.
grant_type=client_credentials
응답은 다음과 같습니다 (가독성을 위해 여기에 인쇄되어 있습니다).
{
"access_token": "ANB7xKhiUZmwltVd3f1odcHHM9VAwg02kwmLwtZwHv3SxGCOWLUf5W4G7X22PRjmR9StvFUqzpVZ1suOfyfOigdi-rnohxyEaSSuZceeLw_9OBW7fXldOG05HEgkeK3N-DBZZZyilodmjA1JWZHbgI3IU7Rmz5IPGyi-sDxHN3KlOr1BDZlLZpXPdFPwEyb6idq-z8AL-blKTSMtNI3_fz3oNBisfrHGUv5tXHoQT4B7FYcvdrap16gTOO7_wNt1zmgLJiUHvyxZgsgBchm_AhohVL-AYgcfCbCR0v7d2hgI4ag35pnZNeujDiBLfnCFcVMlqQGq8UEVZrmU9a8y4pVAGih_EImmghqmSrkxLPYZ800-vIWX-lw",
"token_type": "Bearer",
"expires_in": 300
}
access_token값은 다음과 같은 형식으로 API 호출과 함께Authorization헤더에 전달해야 하는 값입니다.
Authorization: Bearer {access_token}
expires_in값은 액세스 토큰이 유효한 시간 (초) 입니다.
구현 전략
앱이 브라이트코브 API를 간헐적으로 호출하는 경우expires_in파라미터를 무시하고 호출할 때마다 새 액세스 토큰을 가져오는 것이 좋습니다. 이 경우 처리 순서는 다음과 같습니다.
반면, 앱이 긴 보고서 생성과 같은 여러 API 호출을 빠르게 연속해서 자주 수행한다는 것을 알고 있다면 필요할 때만 액세스 토큰을 가져오는 것이 더 효율적일 것입니다. 이를 수행하는 두 가지 기본 방법이 있습니다.
- 계속해서 API 호출을 시도하고 이에 대한 응답으로
UNAUTHORIZED오류가 발생하면 새 토큰을 가져와서 API 호출을 다시 실행하세요. 이 경우 처리 순서는 다음과 같습니다.
호출 실패 확인과 함께 토큰 가져 오기 - 또 다른 접근 방식은 토큰을 가져올 때마다 현재 시간 (Epoch 초) 에
expires_in값을 추가한 다음 이후 API 호출 시 만료 시간을 현재 시간과 비교하여 새 토큰을 가져와야 하는지 확인하는 것입니다. 이 경우 처리 순서는 다음과 같습니다.
만료 확인과 함께 토큰 가져 오기
우편 배달부와 불면증
REST API에 대한 몇 가지 유용한 테스트 도구는 Brightcove OAuth 시스템과 함께 작동하여 액세스 토큰을 얻도록 설정할 수 있습니다. 가장 널리 사용되는 두 가지 크로스 플랫폼 도구에 대해이 작업을 수행하는 단계가 포함 된 가이드가 있습니다.
코드 샘플
다음은 시작하는 데 도움이되는 몇 가지 코드 샘플입니다.
쉘 스크립트 예
첫 번째 예는 위의 첫 번째 구현 논리를 구현하는 셸 스크립트입니다. 사용자로부터 입력을 받고 항상 새 토큰을 가져온 다음 API를 호출합니다. 스크립트는 모든 Brightcove API에서 작동하며 앱을 빌드 할 때 API 호출을 테스트하는 데 유용 할 수 있습니다.
