WebAPI 응답 추적을 어떻게 활성화합니까?

Question

WebAPI 4.0에 기반한 서비스가 있지만 일부 클라이언트에서 XML 대신 JSON을 받는데 문제가 있습니다. 실제 서비스의 WebAPI 내부에서 어떤 일이 벌어지고 있는지 어떻게 볼 수 있습니까?

Answer 1

컴파일 및 배치 코드베이스가이 세트가 있는지 확인하십시오 : 로그 파일에이 물건을 볼 수

<configuration> 
    <system.diagnostics> 
    <trace autoflush="false" indentsize="4"> 
     <listeners> 
     <add name="myListener" 
      type="System.Diagnostics.TextWriterTraceListener" 
      initializeData="E:\CompressedLogs\Service1-WebApi-TraceOutput.log" /> 
     <remove name="Default" /> 
     </listeners> 
    </trace> 
    </system.diagnostics> 
</configuration> 

:

public static class WebApiConfig 
{ 
    public static void Register(HttpConfiguration config) 
    { 
     // etc. 

     config.EnableSystemDiagnosticsTracing(); 

     // etc. 
    } 
} 

이 그런 다음 Web.config 파일이 추가
