인프런 커뮤니티 질문&답변

 안녕하세요 자유게시판을 어느정도 구현해서 netlify를 통해 배포해보려고 하니 cors 문제로 api가 작동하지 않습니다. 어떻게 해야 해결할 수 있을까요 ?

Access to fetch at 'https://backendonline.codebootcamp.co.kr/graphql' from origin 'https://brilliant-rabanadas-0c6769.netlify.app' has been blocked by CORS policy: Response to preflight request doesn't pass access control check: The 'Access-Control-Allow-Origin' header has a value 'http://localhost:3000' that is not equal to the supplied origin. Have the server send the header with a valid value, or, if an opaque response serves your needs, set the request's mode to 'no-cors' to fetch the resource with CORS disabled.
