[http] CORS Access-Control-Allow-Headers 와일드 카드가 무시됩니까?

해당 CORS 헤더는 *값으로 지원하지 않으며 유일한 방법은 다음으로 바꾸는 것 *입니다.

자주하는 질문:

• 왜 Access-Control-Allow-Headers, Access-Control-Expose-Headers, Access-Control-Allow-Methods값은 매우 긴?

  그것들은 *구문을 지원하지 않으므로 웹에서 가장 일반적인 (그리고 이국적인) 헤더를 다양한 형식으로 수집했습니다. # 1 # 2 # 3 _{(그리고 때때로 목록을 업데이트 할 것입니다)}

• Header unset ______구문 을 사용하는 이유는 무엇 입니까?

  GoDaddy 서버 (내 웹 사이트가 호스팅됩니다 ..)에는 헤더가 이미 설정되어있는 경우 이전 값이 기존 값과 결합되는 이상한 버그가 있습니다.이 방식으로 기존 값을 “사전 정리”합니다. _{(정말로 빠른 && 더러운 솔루션)}

• ‘있는 그대로’사용하는 것이 안전한가요?

  글쎄 .. 다음 “폴더”위치에서 제공되는 스크립트 (PHP, HTML, …) 및 리소스 (.JPG, .JS, .CSS)에 대한 헤더를 제한하기 때문에 대부분 대답은 YES.htaccess 입니다. 선택적으로 Access-Control-Allow-Methods라인 을 제거 할 수 있습니다. _{또한 Connection, Time-Zone, Keep-Alive와 DNT, Accept-Ranges, Vary, X-UA-Compatible, X-Frame-Options, X-Content-Type-Options그리고 X-Xss-Protection내 온라인 서비스를 사용하고 단지 제안입니다 .. 너무 사람들을 제거 주시기 …}
