팀 여러분,
팀용 커뮤니티 앱에 discourse-zoom을 통합하려고 시도하고 있습니다. 서버 간(server-to-server) OAuth 앱을 생성하고 검증한 후 모든 것이 정상적으로 보였으며, Meetings SDK를 인증하는 데 필요한 ‘/auth/oauth2_basic/callback’ URL을 얻기 위해 ‘discourse-oauth2-basic’ 플러그인을 설치했습니다. SDK를 구성하고 브라우저에 생성된 URL을 붙여넣어 인증 플로우를 시작하려고 할 때, 다음과 같은 오류가 계속 발생하고 있습니다.
조사를 해본 결과, 저변의 OmniAuth 전략 코드에서 CSRF 예외가 발생한다는 것을 발견했습니다.
(oauth2_basic) Authentication failure! csrf_detected: OmniAuth::Strategies::OAuth2::CallbackError, csrf_detected | CSRF detected

인증 부분을 어떻게 진행해야 할지 올바른 방향으로 안내해 주실 수 있을까요? 보안상의 우려 때문에 'options.provider_ignores_state’를 조정하는 것은 좋은 생각이 아닌 것 같고, ‘callback’ URL만 접근하는 경우 'omniauth.state’가 초기화되는지 확신할 수도 없습니다. 또한 OmniAuth에 충분히 익숙하지 않아서 이 문제를 효과적으로 트러블슈팅하는 방법을 모르겠습니다.
discourse-zoom 설치/구성 가이드에는 'discourse-oauth2-basic’의 사용에 대해 명시적으로 언급되어 있지 않습니다. Meetings SDK를 인증하는 데 도움이 되는 더 나은 방법이나 더 호환성이 높은 플러그인이 있을까요?
감사합니다.
