안녕하세요
스프링 부트로 플러터 앱에서 access 토큰을 가져와 https://kapi.kakao.com/v2/user/me 에 카카오정보를 요청했습니다.
굉장히 낮은 빈도로 성공하고 아니면 401 오류가 나오네요…
앱 ID :935812
안녕하세요.
해당앱의 3일간 로그상 /v2/user/me의 401 오류는 1건입니다. (만료된 토큰으로 요청)
여러번 에러 발생했다면, 앱을 특정하지 못하는 상황으로 request 데이터나 헤더가 훼손되었을 것 같습니다.
error response body에 어떤 메시지로 응답받았는지 기재 부탁드려요.
responseCode : 401

성공한 요청 도 없나요??
코드는 이렇습니다
Map<String, Object> userInfo = new HashMap<>();
String reqURL = “https://kapi.kakao.com/v2/user/me”;
try {
URL url = new URL(reqURL);
HttpURLConnection conn = (HttpURLConnection) url.openConnection();
conn.setRequestMethod(“GET”);
// 요청에 필요한 Header에 포함될 내용
conn.setRequestProperty("Authorization", "Bearer " + access_Token);
int responseCode = conn.getResponseCode();
log.debug("responseCode : " + responseCode);
System.out.println("responseCode : " + responseCode);
BufferedReader br = new BufferedReader(new InputStreamReader(conn.getInputStream()));
[rest api 예제] java (spring boot) - 카카오 로그인, 카카오 친구목록 조회, 나에게 메시지 발송
에러 trace 말고 카카오에서 전달한 에러 Response Body 확인 해주시겠어요?
InputStream stream = conn.getErrorStream();
if (stream != null) {
try (Scanner scanner = new Scanner(stream)) {
scanner.useDelimiter("\\Z");
response = scanner.next();
}
System.out.println("error response : " + response);
}
해당 디벨로퍼스 앱으로 조회되는 로그는 1건 빼고 모두 성공 응답입니다.
8월2일 3일 약 18건 가량
error response : {“msg”:“this access token does not exist”,“code”:-401}
이런식으로 나옵니다
제가 클라이언트 쪽에서 토큰을 서버로 보낸뒤 유저정보를 가져오는 로직을 짰는데
클라이언트 쪽에서 토큰을 서버로 전달하는 과정에서 문제가 생긴거겠죠?
동일한 로직으로 성공한 이력이 있으니 토큰이 전달과정에 인코딩 문제 같은게 발생했을 것 같네요.
참고로 클라이언트에서 서버단으로 액세스 토큰을 전달하는 것은 권장하지 않습니다.
플러터에 카카오와 교신을 일임하고
조회된 사용자 정보를 받아서 처리하고 JWT토큰 발행해 넘겨주는 방식을 추천합니다.
어 고민하던 부분이었는데 역시 토큰이 왔다갔다하는건 문제가 있는 로직이었군요!
감사합니다 좋은 하루 되시길…!
