1. Naver open api

https://developers.naver.com/docs/common/openapiguide/

01. talend api test 사용

-1. 예제를 활용한 검색

• Header에 발급받은 값을 입력
  
  
  

-2. query 값 직접 넣어보기

• utf-8 encoding을 해주어야 한다
  • %로 된 값 확인 후 입력
    
    
    
    

02. Spring boot로 구현

• talend api test랑 비교하면서 작성
  

-1. Server

• controller / ServerApiController.java

package com.example.server.contoller;
