[asp.net-mvc] ASP.NET MVC 및 IIS7에서 원시 HTTP 요청 / 응답 로깅

를 사용 IHttpModule하고 BeginRequestand EndRequest이벤트를 구현하십시오 .

은 “원시”모든 데이터는 사이에 존재 HttpRequest하고 HttpResponse그것은 단지 하나의 원시 형식이 아닙니다. Fiddler 스타일 덤프를 작성하는 데 필요한 부분은 다음과 같습니다 (원시 HTTP와 비슷).

request.HttpMethod + " " + request.RawUrl + " " + request.ServerVariables["SERVER_PROTOCOL"]
request.Headers // loop through these "key: value"
request.InputStream // make sure to reset the Position after reading or later reads may fail

답변 :

"HTTP/1.1 " + response.Status
response.Headers // loop through these "key: value"

참고 당신은 응답 스트림을 읽을 수 없습니다 당신이 출력 스트림에 필터를 추가하고 사본을 캡처 할 수 있도록.

당신의에서 BeginRequest, 당신은 응답 필터를 추가해야합니다 :

HttpResponse response = HttpContext.Current.Response;
OutputFilterStream filter = new OutputFilterStream(response.Filter);
response.Filter = filter;

핸들러 filter에 도달 할 수있는 위치를 저장 하십시오 EndRequest. 에 제안 HttpContext.Items합니다. 그런 다음에 전체 응답 데이터를 얻을 수 있습니다 filter.ReadStream().

그런 다음 OutputFilterStreamDecorator 패턴을 스트림 주위의 래퍼로 사용하여 구현 하십시오.
