<p>httpie가 자체 서명된 인증서 신뢰를 거부합니다.</p>

나는 문제 #480에 대한 논의를 완전히 이해하지 못하지만 근본 원인은 이 문제에 대해 동일할 수 있다고 생각합니다. 자체 서명된 인증서를 신뢰하려면 httpie가 필요합니다. 기술적으로 자체 서명된 중간 인증 기관이지만 해당 기관의 실제 서버 인증서 중 하나를 사용하여 동일한 결과를 얻을 수 있습니다. 이 인증서는 curl을 포함하여 내 Mac(OS 10.12)의 다른 모든 응용 프로그램을 충족합니다. Httpie는 단순히 그것을 신뢰하지 않을 것입니다. 샘플 출력:

--verify=no 를 사용하면 연결이 허용됩니다. 인증서 파일을 변경 없이 PEM 대신 DER 형식으로 변환해 보았습니다.

Httpie는 자체 Python3을 종속성으로 설치한 Homebrew를 통해 설치되었습니다.
