안녕하세요 ㅜ
본론부터 말씀드리면 '한국도로공사' 공공 DB를 가져다 구글맵에 전국에있는 휴게소를 마커로 보여주는것(진행중)
자신의 위치 기준 가까운 휴게소 검색기능(구현 예정)
여기서 구글맵에 전국에있는 휴게소를 띄워줘야 하거든요 ㅜ ..
하지만 계속 세계지도만뜨네요 ㅜ..
요청변수 필수 항목인 serviceKey와 type 넣어준 상태입니다
도대체 이유가 뭔지 .. 모르겠네요 ....
소스첨부 합니다 도와주십시오 ㅜ ..

}API키는 소스 상엔 없지만 10자리 숫자로 이루어진 API키를 넣은 상태입니다
그리고 소스상 요청 URL 주소를 웹브라우저에 그대로 처보면 XML로 잘나옵니다 ㅠ
