자바 스크립에서 refreshToken을 받아 그 토큰으로 자바에서 accessToken을 재발급 받는 코드를 만들었습니다.
private String updateKakaoAccessToken(Member member, String refreshToken) {
String tokenUrl = “https://kauth.kakao.com/oauth/token”;
String restApiKey = myKey;
try {
// 토큰 갱신을 위한 요청 파라미터
String postParams = "grant_type=refresh_token"
+ "&client_id=" + restApiKey
+ "&refresh_token=" + refreshToken;
HttpHeaders headers = new HttpHeaders();
headers.setContentType(MediaType.APPLICATION_FORM_URLENCODED);
HttpEntity<String> entity = new HttpEntity<>(postParams, headers);
// RestTemplate을 사용하여 요청 전송
ResponseEntity<String> response = restTemplate.exchange(tokenUrl, HttpMethod.POST, entity, String.class);
if (response.getStatusCode() == HttpStatus.OK) {
JSONObject jsonResponse = new JSONObject(response.getBody());
String newAccessToken = jsonResponse.getString("access_token");
// 새로운 refresh token이 있으면 저장
if (jsonResponse.has("refresh_token")) {
String newRefreshToken = jsonResponse.getString("refresh_token");
member.updateKakaoRefreshToken(newRefreshToken);
}
memberRepository.save(member);
return newAccessToken;
} else {
log.error("액세스 토큰 갱신 실패. 응답 코드: {}", response.getStatusCode());
return null;
}
} catch (HttpClientErrorException e) {
// HTTP 오류 응답 처리
if (e.getStatusCode() == HttpStatus.FORBIDDEN) {
String errorResponse = e.getResponseBodyAsString();
JSONObject jsonResponse = new JSONObject(errorResponse);
// 오류 메시지와 상세 내용 로그 출력
log.error("권한 오류 발생: {}", errorResponse);
log.error("필요한 권한: {}", jsonResponse.optJSONArray("required_scopes"));
log.error("허용된 권한: {}", jsonResponse.optJSONArray("allowed_scopes"));
} else {
log.error("액세스 토큰 갱신 중 오류 발생: {}", e.getMessage(), e);
}
return null;
} catch (Exception e) {
log.error("액세스 토큰 갱신 중 알 수 없는 오류 발생: ", e);
return null;
}
}
이렇게 만들었습니다.
그런데 실행 하니까 “액세스 토큰 갱신 중 오류 발생: 401 Unauthorized: [no body]” 이렇게 뜨며
