예제

다음 TraceExtension SOAP 확장은 XML 웹 서비스 메서드에 적용될 때 지정된 파일에 SOAP 요청 및 SOAP 응답을 출력합니다. XML 웹 서비스를 사용하여 실행하려면 다음 SOAP 확장이 설치되어 있으면 ASPNET 사용자 계정에 로그 파일이 기록된 디렉터리에 쓸 수 있는 권한이 있어야 합니다.

설명

ASP.NET 확장성 메커니즘을 통해 SOAP 관련 인프라를 빌드할 수 있습니다. ASP.NET SOAP 확장 아키텍처는 클라이언트 또는 서버에서 메시지 처리의 특정 단계에서 메시지를 검사하거나 수정할 수 있는 확장을 중심으로 진행됩니다.

ASP.NET SOAP 확장은 SoapExtension 클래스에서 파생됩니다. 및 GetInitializer 메서드는 Initialize 성능을 향상시키기 위해 SOAP 확장을 초기화하기 위한 대체 메커니즘을 제공합니다. ProcessMessage 는 정의된 각 단계에서 SoapMessageStage메서드가 호출되므로 대부분의 SOAP 확장의 핵심이며 SOAP 확장이 특정 SOAP 확장의 원하는 동작을 수행할 수 있도록 합니다. SOAP 요청 또는 SOAP 응답을 ChainStream 수정해야 하는 SOAP 확장의 경우 유선으로 전송할 제안된 데이터를 수신할 수 있는 기회를 제공합니다.

생성자

Name Description
SoapExtension()

SoapExtension 클래스의 새 인스턴스를 초기화합니다.

메서드

Name Description
ChainStream(Stream)

파생 클래스에서 재정의되는 경우 SOAP 요청 또는 응답을 포함하는 메모리 버퍼에 대한 SOAP 확장 액세스를 허용합니다.
Equals(Object)

지정된 개체가 현재 개체와 같은지 여부를 확인합니다.

(다음에서 상속됨 Object)
GetHashCode()

기본 해시 함수로 사용됩니다.

(다음에서 상속됨 Object)
GetInitializer(LogicalMethodInfo, SoapExtensionAttribute)

파생 클래스에서 재정의된 경우 SOAP 확장에서 XML 웹 서비스 메서드에 적용된 특성을 사용하여 XML 웹 서비스 메서드와 관련된 데이터를 한 번에 성능 비용으로 초기화할 수 있습니다.
GetInitializer(Type)

파생 클래스에서 재정의되는 경우 SOAP 확장에서 한 번에 성능 비용으로 XML 웹 서비스를 구현하는 클래스와 관련된 데이터를 초기화할 수 있습니다.
GetType()

현재 인스턴스의 Type 가져옵니다.

(다음에서 상속됨 Object)
Initialize(Object)

파생 클래스에서 재정의되는 경우 SOAP 확장에서 메서드에 캐시된 GetInitializer(LogicalMethodInfo, SoapExtensionAttribute) 데이터를 사용하여 자신을 초기화할 수 있습니다.
MemberwiseClone()

현재 Object단순 복사본을 만듭니다.

(다음에서 상속됨 Object)
ProcessMessage(SoapMessage)

파생 클래스에서 재정의되는 경우 SOAP 확장이 각각SoapMessage에서 처리할 SoapMessageStage 수 있도록 허용합니다.
ToString()

현재 개체를 나타내는 문자열을 반환합니다.

(다음에서 상속됨 Object)
