How to get raw data from Web Service Request?

I want to check raw data string (raw xml) received by my web service methods (for logging and debugging purposes).

I saw recommendations: to handle 'BeginRequest' event in HttpApplication. But I don't see which field of '开发者_高级运维Request' object contains this POST data?

- Have you seen this answer using tracing? or this one using a SoapExtension

I made following changes in web.cofig to get SOAP(Request/Response) Envelope. It makes trace.log file where all the required information are present

<system.diagnostics>
<trace autoflush="true"/>
<sources>
  <source name="System.Net" maxdatasize="1024">
    <listeners>
      <add name="TraceFile"/>
    </listeners>
  </source>
  <source name="System.Net.Sockets" maxdatasize="1024">
    <listeners>
      <add name="TraceFile"/>
    </listeners>
  </source>
</sources>
<sharedListeners>
  <add name="TraceFile" type="System.Diagnostics.TextWriterTraceListener" initializeData="trace.log"/>
</sharedListeners>
<switches>
  <add name="System.Net" value="Verbose"/>
  <add name="System.Net.Sockets" value="Verbose"/>
</switches>

It would not make sense to keep all the request post data in the request object since it could contain uploaded file and be very big.

I have two solutions for you:

1) Use Fiddler on the server and browse locally the website (using server name and not localhost since Fiddler cannot show localhost request/responses)

2) Use System.Net tracing: http://support.microsoft.com/kb/947285

You can also use WireShark to look at the packets but this will not keep the request response context.
