[서버] 스프링 RestTemplate org.springframework.web.client.HttpClientErrorException: 401 Unauthorized

프로그래밍/서버2021. 3. 1. 20:58

스프링에서 RestTemplate를 이용해서 REST API 테스트 중인데 아래의 에러가 발생했습니다.

 

정확한 원인을 알려주면 좋을텐데 좀 애매하게 알려주네요.

Servlet.service() for servlet [dispatcherServlet] in context with path [] threw exception [Request processing failed; nested exception is org.springframework.web.client.HttpClientErrorException: 401 Unauthorized] with root cause

아래의 부분이 중요한 것 같습니다.

org.springframework.web.client.HttpClientErrorException: 401 Unauthorized

	at org.springframework.web.client.RestTemplate.exchange(RestTemplate.java:600) ~[spring-web-5.0.7.RELEASE.jar:5.0.7.RELEASE]

 

디버깅 로그를 좀 더 자세히 보려면 아래의 과정이 필요합니다.

application.properties 에 아래의 코드를 추가합니다.

logging.level.org.apache.http=DEBUG
logging.level.httpclient.wire=DEBUG

만약 yaml 파일을 쓴다면 아래와 같이 추가해주세요.

logging:
  level:
    org.apache.http: DEBUG
    httpclient.wire: DEBUG

 

그리고 RestTemplate를 만들 때 setRequestFactory를 설정합니다.

RestTemplate restTemplate = new RestTemplate();
restTemplate.setRequestFactory(new HttpComponentsClientHttpRequestFactory());

 

그러면 스프링 로그에서 추가 정보를 얻을 수 있습니다.

Request Header는 이상한 부분이 안보였습니다.

아래 로그는 Response 관련 로그입니다.

{"msg":"ip mismatched! callerIp=123.33.327.41. check out registered ips.","code":-401}

이 부분이 핵심입니다.

 

디벨로퍼에서 정보좀 찾아보니 아래와 같네요 ㅎㅎ;;

devtalk.kakao.com/t/rest-api-ip-mismatched/105585

 

Kakao DevTalk_

카카오 데브톡. 카카오 플랫폼 서비스 관련 질문 및 답변을 올리는 개발자 커뮤니티 사이트입니다.

devtalk.kakao.com

developers-sample앱은 카카오에서 제공하는 샘플앱으로,
디벨로퍼스 내부에서만 테스트 할 수 있도록 IP가 제한되어 있습니다.

 

카카오 디벨로퍼 사이트에서 제공되는 액세스 토큰을 사용해서 생긴 문제였습니다.

제 앱에서 발급받은 액세스 토큰을 사용하니 문제가 사라졌습니다. ㅎㅎ;;
