HTTP POST 호출이 반환됩니다. HTTP 메소드가 OPTIONS로 설정되어 있기 때문에 Mule에서 허용되지 않는 오류가 발생했습니다.

Question

HTTP POST 요청을 받아들이고 각도로 작성된 UI 응용 프로그램에서 호출되는 mule 3.7.3 워크 플로우가 있습니다.

HTTP POST 호출이 Mule에 수행되면 http 메소드가 OPTIONS로 설정된 상태로 메시지가 전송되므로 허용되지 않는 메소드로 실패합니다. 응용 프로그램/json으로 설정된 콘텐츠 형식을 가진 XHR 형식 메시지를 보내는 응용 프로그램의 예상 동작이며 이러한 상황에서는 POST 요청을 보내기 전에 UI 응용 프로그램이 미리 작성된 OPTIONS 요청을 보내 게됩니다.

내 질문은 :

1. UI를에만 POST 요청을 전송하는 것이 가능 그것?
2. Mule이 이것을 처리하는 가장 좋은 방법은 무엇입니까? OPTIONS 호출을 모든 POST 메서드와 함께 RAML 파일에 추가하고 워크 플로를 추가로 만들어야합니까?

CORS 문제가있어

Answer 1

는 OPTIONS 요청은 비행 전 요청입니다.

xmlns:core="http://www.mulesoft.org/schema/mule/core" 

및

http://www.mulesoft.org/schema/mule/cors http://www.mulesoft.org/schema/mule/cors/current/mule-cors.xsd 

는하지만 팔레트에서 드래그하면

<cors:config name="corsConfig" /> 

<flow name="rest-api-main" doc:name="rest-api-main"> 
     <http:listener path="api/${api.version}/*" config-ref="restAPIMainHttpConfig" /> 

     <cors:validate config-ref="corsConfig" publicResource="true" /> 
</flow> 

업데이트 :

는 대중을 모두받을 수있는 옵션을 허용하는 CORS 모듈을 사용하거나 만들 스튜디오에서는 자동으로 추가됩니다.
