CORS 에러?? 이게 뭐시단가...
CORS란? Cross Origin Resource Sharing의 약자이다. 다른 출처(또는 도메인)로 부터 스크립트를 이용한 json과 같은 데이터를 불러올 때 보안상의 이유로 제한하는 것을 뜻한다. https://domain-a.com => https://domain-b.com/data.json 을 요청하는 경우 아래와 같은 에러가 콘솔에 표시된다. 그래서 다른 출처에서 리소스를 불러올때 리소스를 주는 쪽 출처에서 다른 곳에서도 리소스를 읽을 수 있도록 response HTTP에 CORS 헤더를 붙여서 보내줘야한다. 해결방법 클라이언트에서 해결 먼저 클라이언트단에서는 프록시서버를 거치는 방법이 있다. 프록시서버를 요청헤더에 포함시키면 프록시서버가 중간에 가로채서 HTTP 응답
