유튜브 Service Account 인증방식으로 업로드 API 사용 질문
편현장
Google Data API 3.0 을 이용해서 유튜브에 동영상을 올리려고 합니다.
인증방식은 Service Account 방식으로 하려고 하는데 인증이 필요한 API 를 콜하면 401 Unauthorized 오류가 나더란 말입니다.
{
"code" : 401,
"errors" : [ {
"domain" : "youtube.header",
"location" : "Authorization",
"locationType" : "header",
"message" : "Unauthorized",
"reason" : "youtubeSignupRequired"
} ],
"message" : "Unauthorized"
}
그런데 https://developers.google.com/youtube/v3/docs/errors?hl=ko 에 에러 코드 정의된 페이지를 보니깐
This error is commonly seen if you try to use the OAuth 2.0 Service Account flow. YouTube does not support Service Accounts, and if you attempt to authenticate using a Service Account, you will get this error.
라고 "지원안합니다." 라고 명백히 되어있더군요. 그러면 도대체 API 는 왜 있는걸까? 의구심이 들어서 자애스런 자바님들께 다음과 같은 케이스로 사용 경험이 있는지, 아니면 어떻게 해결하셨는지 여쭤봅니다.
- Google Data API 3.0
- Service Account 인증
- 인증이 필요한 API 호출 (playlist, insert, ... )
다음은 작성해놓은 소스입니다.
