The equivalent of Fiddler SOAP request/response stored in database - wcf

Question

I write a lot of WCF services to other services. I have had trouble with getting Fiddler to log the SOAP messages before but now I have that working. But my boss wants something without Fiddler at all where I can take the SOAP message going out and the one coming in logged to the database. I have looked a lot at WCF Logging and Diagnostics and extending it with Database Source Listener but I cant find an implementation of a Database Source Listener to use.
I don't think that's what he even wants. He wants the equivalent of Fiddler's SOAP request/response displays written to the database. Can anyone help me please?

Answer 1

You have two possibilities:
Write custom WCF Trace Listener, calling database procedure to store logging data:
public class AsyncMSMQTraceListener : TraceListener
{
public override void TraceData(TraceEventCache eventCache, string source,
TraceEventType eventType, int id, object data)
{
// eventType like for example TraceEventType.Information
var message = data.ToString();
// Here call datbase save log with message
}
public override void Write(string message)
{
}
public override void WriteLine(string message)
{
}
}
but in this way you'll get trace messages, where request/response is only a part of it.
Write custom Message Inspector class:
public class ConsoleOutputMessageInspector : IDispatchMessageInspector
{
public object AfterReceiveRequest(ref Message request, IClientChannel channel, InstanceContext instanceContext)
{
MessageBuffer buffer = request.CreateBufferedCopy(Int32.MaxValue);
request = buffer.CreateMessage();
// Here you can use buffer.CreateMessage().ToString()
return null;
}
public void BeforeSendReply(ref Message reply, object correlationState)
{
MessageBuffer buffer = reply.CreateBufferedCopy(Int32.MaxValue);
reply = buffer.CreateMessage();
// here you can use buffer.CreateMessage().ToString()
}
}
Note: Regardless which method you choose, I would suggest to make some kind of an asynchronous call to the database to not block normal service flow.
