SOAP(Simple Object Access Protocol)은 일반적으로 널리 알려진 HTTP, HTTPS, SMTP 등을 통해 XML 기반의 메시지를 네트워크상에서 교환하는 프로토콜이다.

원격 프로시져 호출(Remote Procedure Call:RPC) 패턴으로, 네트워크 노드(클라이언트)에서 다른 쪽 노드(서버)쪽으로 메시지를 요청 하고, 서버는 메시지를 즉시 응답하게 된다.
KDSoap은 Qt를 사용하는 C++응용 프로그램에서 SOAP 가능하도록 하는 3rd party 오픈소스 컴포넌트이다. 웹서비스 용 클라이언트 응용프로그램을 만드는데 사용될 수 있으며 전용 웹 서버와 같은 추가구성요소 없이 웹서비스를 생성할 수 있는 수단을 제공한다.

Ok, now run nmake (for Visual Studio) or mingw32-make (for mingw) to build the framework.
빌드 및 설치:
mingw32-make
mingw32-make install
예제:
KDSoap\examples\helloworld_client
KDSoap\examples\helloworld_server
예제 프로젝트 폴더에서 다음과 같이 프로토콜을 정의한 xml 형식 파일이 있다. 컴파일 시 kdwsdl2cpp 에 의해 필요한 소스코드를 생성한다.
helloworld.wsdl

예제를 빌드해서 서버를 실행 하고

클라이언트를 실행하여 메세지를 보내본다.

로컬(localhost)에서 서버와 클라이언트 프로세스간 통신하는데도 사용할 수 있다.
