네이버 지역검색 API를 활용한 맛집 List 제작 - (2)

<순서>

1. application.yml에 naver key 등록

2. 지역검색, 응답 & 이미지검색, 응답 클래스 작성

3. naver client 정보를 이요하여 검색 기능 구현

4. 검색 기능 테스트

 

*application.yml

application.yml에 아래의 코드를 등록한다. 보통 key값이나 개인정보가 있는 경우에 따로 관리한다.

naver:
 url:
  search:
   local: ...
   image: ...
 client:
  id: ...
  secret: ...

 

*SearchLocalReq.java / SearchLocalRes.java

지역검색 요청과 응답에 대한 dto를 따로 만든다.

@Data
@NoArgsConstructor
@AllArgsConstructor
public class SearchLocalReq {
 private String query = "";
 
 private int delay = 1;
 
 private int start = 1;
 
 private String sort = "sim";
 
 public MultiValueMap<String, String> toMultiValueMap() {
  var map = new LinkedultiValueMap<String, String>();
  
  map.add("query", query);
  map.add("display", String.valueOf(display));
  map.add("satrt", String.valueOf(start));
  map.add("sort", sort);
  return map;
 }
}

================================

@Data
@NoArgsConstructor
@AllArgsConstructor
public class SearchLocalRes {
 private String lastBuildDate;
 
 private int total;
 
 private int start;
 
 private int display;
 
 private String category;
 
 private List<SerachLocalItem> items;
 
 @Data
 @NoArgsConstructor
 @AllArgsConstructor
 public static class SearchLocalItem {
  private String title;
  private String link;
  private String description;
  private String telehpone;
  private String address;
  private String readAddress;
  private int mapx;
  private int mapy;
 }
}

 

* SearchImageReq.java / SearchImageRes.java

이미지검색 요청과 응답에 대한 dto를 따로 만든다.

@Data
@NoArgsConstructor
@AllArgsConstructor
public class SearchImageReq {
 private String query = "";
 
 private int delay = 1;
 
 private int start = 1;
 
 private String sort = "random";
 
 private String filter = "all";
 
 public MultiValueMap<String, String> toMultiValueMap() {
  var map = new LinkedultiValueMap<String, String>();
  
  map.add("query", query);
  map.add("display", String.valueOf(display));
  map.add("satrt", String.valueOf(start));
  map.add("sort", sort);
  map.add("filter", filter);
  return map;
 }
}

================================

@Data
@NoArgsConstructor
@AllArgsConstructor
public class SearchImageRes {
 private String lastBuildDate;
 
 private int total;
 
 private int start;
 
 private int display;
 
 private List<SerachImageItem> items;
 
 @Data
 @NoArgsConstructor

 public static class SearchImageItem {
  private String title;
  private String link;
  private String thumnail;
  private String sizeheight;
  private String sizewidth;
 }
}

 

 

*NaverClient.java

application.yml에 저장한 계정정보를 @Component로 등록한다.

@Component
public class NaverClinet {
 @Value("${naver.client.id}");
 private String naverClinetId;
 
 @Value("${naver.client.secret}");
 private Stirng naverClinetSecret;
 
 @Value("${naver.client.local}");
 private Sting naverLocalSearchUrl;
 
 @Value("${naver.client.image}");
 private String naverImageSearchUrl;
 
 public SearchLocalRes localSearch(SearchLocalReq searchLocalReq) {
   var uri = UriComponentsBuilder.fromUriString(naverLocalSearchUrl)
            .queryParams(serachLocalReq.toMultiValueMap())
            .build()
            .encode()
            .toUri();
            
   var headers = new HttpHeaders();
   headers.set("X-Naver-Client-Id", naverClientId);
   headers.set("X-NAVER-Client-Secret", naverClinetSecret);
   headers.setContentType(MediaType.APPLICATION_JSON);
   
   var httpEntity = new HttpEntity<>(headers);
   var responseType = new ParameterTypeReference<SearchImageRes>(){};
   
   var responseEntity = new RestTemplate().exchange(
    uri, HttpMethod.GET, httpEntity, responseType
   );
   
   return responseEntity.getBody();
 }
 
 public SearchImageRes imageSearch(SearchImageReq searchImageReq) {
   var uri = UriComponentsBuilder.fromUriString(naverImageSearchUrl)
            .queryParams(serachImageReq.toMultiValueMap())
            .build()
            .encode()
            .toUri();
            
   var headers = new HttpHeaders();
   headers.set("X-Naver-Client-Id", naverClientId);
   headers.set("X-NAVER-Client-Secret", naverClinetSecret);
   headers.setContentType(MediaType.APPLICATION_JSON);
   
   var httpEntity = new HttpEntity<>(headers);
   var responseType = new ParameterTypeReference<SearchImageRes>(){};
   
   var responseEntity = new RestTemplate().exchange(
    uri, HttpMethod.GET, httpEntity, responseType
   );
   
   return responseEntity.getBody();
 }
}

 

*NaverClientTest.java

NaverClient의 검색 메서드를 테스트하는데, query만 설정해주면 된다.

@SpringBootTest
public class NaverClientTest {
 @Autowired
 private NaverClient naverClient;
 
 @Test
 public void searchLocalTest() {
  var search = new SearchLocalReq();
  search.setQuery("갈비집");
  
  var result = naverClient.searchLocal(search);
  System.out.println(result);
 }
 
 @Test
 public void searchImageTest() {
  var search = new SearchImageReq();
  search.setQuery("갈비집");
  
  var result = naverClient.searchImage(search);
  System.out.println(result);
 }
}
