NEW!! 12시간 안에 끝내는 R 활용 데이터분석 / 시각화

안녕하세요 지금 텍스트데이터 시각화 질문중 마음처럼 불용어 제거가 되지 않아 질문드려요 현재 저는 부총리의 연설문을 바탕으로 시각화 하려고 실습중입니다. 알려주신 방법과 같이 영어를 제거해주고 싶은데 제거가 안 되는데 뭐가 잘못됐을까요?

JdbcTemplate queryForMap 관련 질문이있습니다.

미해결

스프링 DB 2편 - 데이터 접근 활용 기술

공부를 하다보니 궁금한게 있어서 질문 드립니다. 만약 JdbcTemplate를 사용해서 sql = "select * from Table where id = :id"; sql로 특정 id의 값을 사용해 테이블 값을 가져오고 Map<String, Object> param = Map.of("id", id); 으로 정의하고 Map<String, Obeject> result = template.queryForMap(sql, param); 을 했을시에 Object에는 sql문을 사용해서 검색한 데이터들이 들어가는 걸로 이해를 했는데 그러면 String이라고 정해둔 key값에는 무엇이 들어가나요??

dio 패키지는 redirect 처리를 하기 어렵나요?

Node.js express 로 라우터를 설정해 다음과 같은 코드로 http 통신을 했습니다 /api/test1 주소의 post 라우터에서 /api/test2 주소의 post 라우터로 redirect 되는 통신을 테스트 해보았습니다 onPressed: () async { var res = await http.post(Uri.parse("$uri/api/test1"), headers: <String, String>{ 'Content-Type': 'application/json; charset=UTF-8', }, body: jsonEncode( { "key1": "1000", }, )); if (res.statusCode == 307) { var newURL = res.headers["location"]; print(res.body); res = await http.post(Uri.parse("$uri$newURL"), headers: <String, String>{ 'Content-Type': 'application/json; charset=UTF-8', }, body: jsonEncode( { "key1": "1000", }, )); print(res.body); } else { var data = res.body; print(data); } }, 테스트 결과 제가 데이터를 올바르게 전송할 수 있었습니다 그리고 이번에 선생님의 강의를 듣고 dio라는 패키지를 알게되어서 dio 패키지를 통해서 똑같은 통신 테스트를 해 보았습니다 onPressed: () async { final dio = Dio(BaseOptions( contentType: "application/json", followRedirects: false, maxRedirects: 5, )); final url = "$uri/api/test1"; final body = {'key1': '1000'}; final headers = {'Content-Type': 'application/json'}; try { Response res = await dio.post( url, data: body, ); if (res.statusCode == 307) { final redirectUrl = res.headers.value("location"); final redirectRes = await dio.post( redirectUrl!, data: body, options: Options( headers: headers, method: "POST", ), ); print(redirectRes.data); } else { final data = res.data; print(data); } } catch (e) { print("error 발생 $e"); } }, followRedirects 을 true 로 해도 307 코드를 해결하지는 못하는것 같습니다 flutter: error 발생 DioError [DioErrorType.response]: Http status error [307] 어떻게 dio 패키지로 redirect 를 처리 할 수 있을까요?

1 - I문제 return에 대해서

미해결

10주완성 C++ 코딩테스트 | 알고리즘 코딩테스트

안녕하세요 강사님. 포켓몬스터 이다솜 문제에 대한 강의와 답지에 나와있는 코드에는 return 0;이 없는데, return 0;을 넣어서 코드를 작성하면 틀리게 되는것인가요? return 0;이 없는 이유가 궁금합니다. 또한, cout << mp[s] << "\n"; 에서 '\n'으로 작성하여 제출해도 정답이라고 나오는데 "\n"과 '\n'의 차이가 무엇입니까? 추가적으로 cout << "DA\n"; 과 cout << "DA" << '\n'; 의 차이는 무엇인가요??

정렬 기능이랑 튀어나오는게 무슨 관계인가요?

해결됨

[코드캠프] 시작은 프리캠프

이게 정렬하지 않은 block요소(div)+기본값(row)상태로 body가 아래 튀어나와있고 이게 column값을 줘서 정렬된 상태로 튀어나온 부분이 사라졌습니다. div가 block요소이고 정렬이 안된 row상태이니 위처럼 튀어나오는건 이해할 수 있습니다. 그런데 column을 줘서 수직으로 정렬해도 튀어나오는건 그대로여야하지 않나요? 왜 튀어나온게 들어가는거죠?

강의 (3:38)에서 GridSearchCV 관련 질문

미해결

[개정판] 파이썬 머신러닝 완벽 가이드

안녕하세요 선생님. 먼저 좋은 강의 감사합니다. 다름이 아니라 제가 GridSearchCV를 통해 랜덤 포레스트 코드를 실행하였는데 제가 첨부한 사진과 같은 오류가 나왔습니다. 결과는 문제 없지 나왔지만 어떤 부분에 문제가 생겼는지 궁금하여 질문을 드립니다. 제가 예상하기로는 선생님의 get_human_dataset()에서 y_train이 데이터 프레임 형식으로 추출이 되는데, 여기서는 시리즈 형태 혹은 ndarray 형태로 넣어야 되는 건지 추측을 해봅니다. 감사합니다.

Principal 인터페이스와 User 클래스의 관계

해결됨

스프링 시큐리티

안녕하세요. 강의를 듣던 중 해결되지 않는 의문이 생겨 질문드립니다. 강의에서 Principal 은 인터페이스이며 UserDetailsService 에서 반환한 User 클래스가 구현체로 사용된다고 말씀해주셨는데 여기서 의문이 생겼습니다. 확인해보니 Principal 은 User 클래스의 인터페이스가 아닌 Authentication 의 구현체로 사용되는 UsernamePasswordAuthenticationToken 의 최상위 인터페이스였습니다. 하지만 Authentication에서 User 객체를 받아오는 메서드의 이름도 getPrincipal() 입니다. 그렇다면, 위 그림에서 나타난 Principal 인터페이스와 User 객체를 반환하는 getPrincipal() 의 principal 은 서로 다른 의미로 쓰이는 건가요? 디버깅을 해봐도 아래와 같이 Principal 인터페이스를 구현하는 XxxAuthenticaionToken 객체가 Authentication 타입으로 받아지고 User 객체는 그냥 Object 타입으로 받아져서 혼동이 되어 질문드립니다.

안녕하세요. 개발하다 궁금한 사항이 있어 질문드립니다. spring을 이용해 백엔드 서버를 구축하고 있는데 디바이스(안드로이드)와 http 통신, tcp/ip socket 통신 두가지를 모두 구현해야 합니다. 이럴 경우에는 java의 socket 관련 라이브러리를 사용해서 소켓 서버를 만들고 서블릿을 이용한 웹서버도 만들어 두 개를 동시에 실행시켜야 하는지 아니면 다른 방식으로 구현해야 하는지 문의드립니다.

재귀호출 질문입니다

미해결

홍정모의 따라하며 배우는 C언어

n=4가 되었을 때 이처럼 함수가 중첩된 상태라고 저는 이해했고, n=4가 되어 if문에 들어가지 않게 되자 원래 myfunc함수에서 if(n < 4)//stop condition my_func(n + 1); printf("Level %d, address of variable n = %p\n", n, &n); 이 부분에 있는 myfunc때문에 이 밑에 있는 printf("Level %d, address of variable n = %p\n", n, &n); 가 4번 실행 못한 상태가 되었기 때문에 지금 기준 20, 21번 줄을 반복하면서(처음에 중첩되면서 못 돈 부분들을 돌고 있음) myfunc함수가 myfunc안에 없었다면 이런일도 없었겠지만 안에 있는 myfunc함수 때문에 출력이 못된 부분들이 마지막에 순차적으로 나오는 것이라고 이해하면 될까요?
