네이버 쇼핑 api랑 서비스 연결하기

네이버 쇼핑 검색 클래스를 만든다 NaverShopSearch

package com.sparta.week04.utils;

import com.sparta.week04.models.ItemDto;
import org.json.JSONArray;
import org.json.JSONObject;
import org.springframework.http.*;
import org.springframework.stereotype.Component;
import org.springframework.web.client.RestTemplate;

import java.util.ArrayList;
import java.util.List;

@Component
public class NaverShopSearch {
    public String search(String query) {//이건 검색어받을때

        RestTemplate rest = new RestTemplate();
        HttpHeaders headers = new HttpHeaders();
        headers.add("X-Naver-Client-Id", "본인계정으로 받은 id");
        headers.add("X-Naver-Client-Secret", "본인계정으로 받은 시크릿 아이디 ~");
        String body = "";

        HttpEntity<String> requestEntity = new HttpEntity<String>(body, headers);
        ResponseEntity<String> responseEntity = rest.exchange("https://openapi.naver.com/v1/search/shop.json?query="+query, HttpMethod.GET, requestEntity, String.class);
        HttpStatus httpStatus = responseEntity.getStatusCode();
        int status = httpStatus.value();
        String response = responseEntity.getBody();
        System.out.println("Response status: " + status);
        System.out.println(response);


        return response;
    }

    public List<ItemDto> fromJSONtoItems(String result){
        JSONObject rjson = new JSONObject(result);
        System.out.println(rjson);
        JSONArray items = rjson.getJSONArray("items");
        List<ItemDto> itemDtoList= new ArrayList<>();
        for (int i=0; i<items.length(); i++) {
            JSONObject itemJson =  items.getJSONObject(i);
            ItemDto itemDto = new ItemDto(itemJson);
            itemDtoList.add(itemDto);
        }
        return itemDtoList;

    }


}

 

데이터를 들고다닐 클래스 ItemDto

package com.sparta.week04.models;

import lombok.Getter;
import org.json.JSONObject;

@Getter
public class ItemDto {
    private String title;
    private String link;
    private String image;
    private int lprice;

    public ItemDto(JSONObject itemJson) {
        this.title = itemJson.getString("title");
        this.link = itemJson.getString("link");
        this.image = itemJson.getString("image");
        this.lprice = itemJson.getInt("lprice");
    }
}

 

그리고 검색요청을 받을 컨트롤러 

package com.sparta.week04.controller;

import com.sparta.week04.models.ItemDto;
import com.sparta.week04.utils.NaverShopSearch;
import lombok.RequiredArgsConstructor;
import org.springframework.web.bind.annotation.GetMapping;
import org.springframework.web.bind.annotation.RequestParam;
import org.springframework.web.bind.annotation.RestController;

import java.util.List;

@RequiredArgsConstructor // final 로 선언된 클래스를 자동으로 생성합니다.
@RestController // JSON으로 응답함을 선언합니다.
public class SearchRequestController {

    private final NaverShopSearch naverShopSearch;

    @GetMapping("/api/search")
    public List<ItemDto> getItems(@RequestParam String query) {
        String resultString = naverShopSearch.search(query);
        return naverShopSearch.fromJSONtoItems(resultString);
    }
}
