이노비즈 API로 GPTs만들어 정부지원사업 검색하기

소개

이노비즈사이트의 API를 발급받아 정부지원사업 검색하는 GPTs 제작

진행 방법

1. GPTs에서 Action기능 사용

1)기본 구성화면

2) 스키마 넣기

이 스키마가 지난번엔 잘 되지 않았어요.
안되었던 이유는 잘 모르겠는데 이번에는 꽤 깔끔하게 잘 정리 되었어요.

3) 스키마 만들기

(1) 기업마당 접속

(2) API사이트

(3) 사용신청

(4) 정보입력

여기에서 입력항목 선택
1번방법 : IP주소 - 내 PC주소 넣어 발급받음
2번방법 : 시스템URL - bizinfo.com 넣음. ㅋㅋㅋㅋ
발급 받은 후에 메일로 메시지가 옵니다.

(5) API키 이거 쓰면 되구요

(6) 아랫쪽에 샘플코드와 응답예시가 있어요.

여기에서 샘플코드를 복사하세요.

4) 스키마 만들기

(1) 복사한 샘플로 이제 챗지피티에게 스키마를 만들어 달라고 합니다.

https://www.bizinfo.go.kr/uss/rss/bizinfoApi.do?crtfcKey=자신의API키

이렇게 넣고 엔터만 쳐도 스키마를 만들어줘요. 응답은 아래와 같아요.

        '400':
          description: Bad request. Typically occurs if required parameters are missing.
        '401':
          description: Unauthorized. The `crtfcKey` is missing or invalid.
        '500':
          description: Server error. An unexpected error occurred on the server side.

그런데 왜 API 샘플코드는 복사 했는가?
이렇게 하면 에러가 나요.
그래서 샘플 코드를 넣으면

/* Java 샘플 코드 */
import java.io.InputStreamReader;
import java.net.HttpURLConnection;
import java.net.URLEncoder;
import java.io.BufferedReader;
import java.net.URL;
import java.io.IOException;

public class ApiExplorer {
	public static void main(String[] args) throws IOException {
		StringBuilder urlBuilder = new StringBuilder("http://X.X.X.X:X/test?cftfcKey=XXXXX"); /*URL*/
		URL url = new URL(urlBuilder.toString());
		HttpURLConnection conn = (HttpURLConnection) url.openConnection();
		conn.setRequestMethod("GET");
		conn.setRequestProperty("Content-type", "application/json");
		System.out.println("Response code: " + conn.getResponseCode());
		BufferedReader rd;
		
		if (conn.getResponseCode()>=200 && conn.getResponseCode() <=300){
			rd = new BufferedReader(new InputStreamReader(conn.getInputStream()));
		} else {
			rd = new BufferedReader(new InputStreamReader(conn.getErrorStream()));
		}
		
		StringBuilder sb = new StringBuilder();
		String line;
		while ((line = rd.readLine()) != null) {
			sb.append(line);
		}
		rd.close();
		conn.disconnect();
		System.out.println(sb.toString());
	}
}

이걸로 스키마 만들어줘.
