안녕하세요.

AccessToken을 이용하여 아래 소스처럼 로그인 고객 정보를 얻을려고 하는데 아래와 같은 에러가 발생합니다.

허용 IP는 아무것도 없이 사용중입니다.

확인 부탁 드립니다.
감사합니다.

앱ID: 886997

에러내역은 이렇습니다.

[tim.l]

허용IP를 등록하지 않아서 에러 발생하는 것으로 보입니다.
에러 응답 Body 내역을 확인하시면 자세한 에러 메시지 확인하실 수 있습니다.

확인 부탁드려요.

허용 IP는 아무것도 없이 사용중입니다.

허용IP 에 IP 하나가 등록되어 있는 것으로 보이는데요. 886997 디벨로퍼스앱 설정이 맞는지 확인 부탁드려요.

[mingg]

설정을 확인해보니, 제가 글 작성 이후에 ip를 등록해서 확인해보느라, 등록이 되어있는게 맞았습니다…

제가 답글에 남겨드린 에러가 제 개인ip주소를 등록했던 상태였는데,
허용 ip를 등록하지 않아서 발생하는 에러라면 어떤 ip주소를 등록해야 할까요?
로컬 ip주소를 등록해도 동일한 에러가 발생합니다.

[mingg]

지금은 내어플리케이션에 허용ip는 127.0.0.1로 등록을 해두었고,
redirect url도 잘 맞게 등록해두었습니다.

컨트롤러에서 어디서 에러가 발생하는지 확인을 위해 출력상태를 찍어봤습니다.
