"서비스 계정"승인 액세스를 사용하여 Google API를 호출하려고합니다. Google API 콘솔의 서비스 탭에서 ".pk2"파일을 다운로드하고 "URL Shortener API"를 활성화했습니다. 언제든지 API (URL 단축키 또는 애드 센스)를 호출하려고합니다. 나는 다음과 같은 예외를 가지고 -Google API에 액세스 할 때 보조금이 잘못되었습니다.

아래는 코드입니다 - 모든 "서비스 계정"의
HttpTransport HTTP_TRANSPORT = new NetHttpTransport();
JsonFactory JSON_FACTORY = new JacksonFactory();
File privateKey = new File(ReportAdsense.class.getResource("mykey.p12").toURI());
GoogleCredential credential = new GoogleCredential.Builder().setTransport(HTTP_TRANSPORT)
.setJsonFactory(JSON_FACTORY)
.setServiceAccountId("[email protected]")
.setServiceAccountScopes(UrlshortenerScopes.URLSHORTENER)
.setServiceAccountPrivateKeyFromP12File(privateKey)
.build();
Urlshortener service = new Urlshortener.Builder(new NetHttpTransport(), JSON_FACTORY, null).setHttpRequestInitializer(credential).build();
UrlHistory history = service.url().list().execute();
