Android에서 .NET 서버로 HTTPS Post 요청을하는 방법은 무엇입니까?

나는 안드로이드 애플 리케이션에서 일하고 있으며, 친구는 훨씬 복잡한 .NET 서버 코드로 서비스를하고있다. 지금 내가 POST로 전송 한 JSON 데이터와 그로부터받은 JSON 데이터가 HTTPS를 초과해야한다는 사실을 알게되었습니다. 내가 찾은 모든 자습서는 표준 HTTP 용이거나 보안 연결을 처리하기위한 여러 클래스 작성이 필요합니다. 나는 안드로이드 개발에 처음이기 때문에 이상적이지는 않을 것이다. 현재 코드가 보안 연결없이 서버에서 데이터를 가져올 지 확신 할 수 없습니다.Android에서 .NET 서버로 HTTPS Post 요청을하는 방법은 무엇입니까?

어디서부터 시작해야합니까? 어떤 변화가 필요합니까?

필자는 필요에 따라 추가 정보를 제공해 드리겠습니다. 저는이 코드를 1 주일 이상 사로 잡았습니다. 정보를 요청할 때 가능한 한 서술 적으로 작성하십시오.

글쎄, 나는 그것이 "가치"를 가지고 있다고 생각하지만, 나는 내용 부분을 파고 보면 내용 길이가 0이다. 그리고 contentType은 null이다. – mattcoker

'response.getStatusLine(). getStatusCode()'의 값은 무엇입니까? – trebron
