HTTP 엔드 포인트로 뮬 파일 다운로드

플로우가 끝날 때 파일 다운로드를 담당하는 HTTP 엔드 포인트가 오류입니다. 전달 된 URL 대신 http://:80/과 계속 통신을 시도합니다. 여기서 내가 뭘 잘못하고 있니? --- 다윗HTTP 엔드 포인트로 뮬 파일 다운로드

큰 감사를

: "페이로드는"? –

URL에서 'http : //'를 뺀 – Thaneofife

: 이것은 내 마지막 솔루션입니다 귀하의 흐름이 교대 시간에 몹시 신경을 쓰는 수있는 http:outbound-endpoint를 사용하여, 그래서 (나는 아래에서 자세히거야 문제는 제외) 좋아 보인다, http:rest-service-component을 사용할 수 있습니다.

다음 문제는 파일 끝점의 outputPattern에 있습니다.이 시점에서 message.payload은 (부분) URL이 아닌 HTTP 끝점의 응답이됩니다. 파일 이름을 미리 계산하여 플로우 변수에 저장 한 다음 사용해야합니다.

굉장한 솔루션이지만 rest-service-component가 followRedirects를 수행하지 않습니까? 나는 .pdf로 끝나지 않는 것을 걸러 내기 위해 노력할 것입니다. pdf 로의 리다이렉트이기 때문에 3 번째 결과로 죽어 가고있다. – Thaneofife

오, 문제 없어요.'rest-service-component'는 기본적으로 20x가 아닌 것을 거부하도록 구성되어 있습니다. 리디렉션을 따르도록 config를 찾을 수 있는지 보도록하겠습니다. –

확인 확인 리디렉션에 대한 내 대답을 검토했습니다. 참고 문법을 좀 더 밝게하기 위해 MEL에'org.mule.util.StringUtils'을 전역 적으로 가져 왔습니다. –
