How to log http level stream from WCF SOAP client on .NET Core?












1















Background: I'm maintaining an integration platform that pulls data from various unreliable APIs. Some of those actions generate potentially high costs, so for diagnostic purposes, every outgoing and incoming message is logged to disk to a separate file. For REST-like APIs, I use a simple wrapper on the network stream that also saves data to a file. For .NET Classic SOAP client, I have a helper that dynamically wraps SoapHttpClientProtocol to use the same network stream logging mechanism.



With .NET Standard 2.0 and .NET Core, the only supported way to write SOAP clients is WCF. How do I programmatically configure WCF SOAP client to log the HTTP incoming/outgoing streams to separate files, preferrably with configurable names?



My current sample client code:



public abstract class ServiceCommunicatorBase<T>
where T : IClientChannel
{
private const int Timeout = 20000;

private static readonly ChannelFactory<T> ChannelFactory = new ChannelFactory<T>(
new BasicHttpBinding(),
new EndpointAddress(new Uri("http://target/endpoint")));

protected T1 ExecuteWithTimeoutBudget<T1>(
Func<T, Task<T1>> serviceCall,
[CallerMemberName] string callerName = "")
{
// TODO: fixme, setup logging
Console.WriteLine(callerName);

using (var service = this.CreateService(Timeout))
{
// this uses 2 threads and is less than ideal, but legacy app can't handle async yet
return Task.Run(() => serviceCall(service)).GetAwaiter().GetResult();
}
}

private T CreateService(int timeout)
{
var clientChannel = ChannelFactory.CreateChannel();
clientChannel.OperationTimeout = TimeSpan.FromMilliseconds(timeout);
return clientChannel;
}
}

public class ConcreteCommunicator
: ServiceCommunicatorBase<IWCFRemoteInterface>
{
public Response SomeRemoteAction(Request request)
{
return this.ExecuteWithTimeoutBudget(
s => s.SomeRemoteAction(request));
}
}

    I was working on the very same problem a week or two ago, there isn’t a lot of resources out there from what I could tell. Don’t have my computer with me, but I’ll be sure to post my solution whenever I get time!

  • Might’ve been a different problem I recall now but, I think I used: docs.microsoft.com/en-us/dotnet/api/… and then I sent along a message-header that way that I then filtered on the receiving end. Typing on my phone, sorry. I’ll elaborate more and post my solution on Monday! More info: docs.microsoft.com/en-us/dotnet/api/…

I've managed to log messages using IClientMessageInspector attached via a configurable behaviour. There's some documentation for Message Inspectors on MSDN but it's still vague (and somewhat out of date, netstandard-2.0 API surface is slightly different.



I had to move from using the ChannelFactory<T> to using the actual generated proxy class. Working code (cut for brevity):



var clientChannel = new GeneratedProxyClient(
new BasicHttpBinding { SendTimeout = TimeSpan.FromMilliseconds(timeout) },
new EndpointAddress(new Uri("http://actual-service-address"));

clientChannel.Endpoint.EndpointBehaviors.Add(new LoggingBehaviour());


Service classes:



// needed to bind the inspector to the client channel
// other methods are empty
internal class LoggingBehaviour : IEndpointBehavior
{
public void ApplyClientBehavior(ServiceEndpoint endpoint, ClientRuntime clientRuntime)
{
clientRuntime.ClientMessageInspectors.Add(new LoggingClientMessageInspector());
}
}

internal class LoggingClientMessageInspector : IClientMessageInspector
{
public object BeforeSendRequest(ref Message request, IClientChannel channel)
{
var correlationId = Guid.NewGuid();
this.SaveLog(ref request, correlationId, "RQ");

return correlationId;
}

public void AfterReceiveReply(ref Message reply, object correlationState)
{
var correlationId = (Guid)correlationState;
this.SaveLog(ref reply, correlationId, "RS");
}

private void SaveLog(ref Message request, Guid correlationId, string suffix)
{
var outputPath = GetSavePath(suffix, correlationId, someOtherData);
using (var buffer = request.CreateBufferedCopy(int.MaxValue))
{
var directoryName = Path.GetDirectoryName(outputPath);
if (directoryName != null)
{
Directory.CreateDirectory(directoryName);
}

using (var stream = File.OpenWrite(outputPath))
{
using (var message = buffer.CreateMessage())
{
using (var writer = XmlWriter.Create(stream))
{
message.WriteMessage(writer);
}
}
}

request = buffer.CreateMessage();
}
