WCF Service custom message inspector

问题

I built a WCF Service that uses custom username and password authentication and I am testing it from the client app with the following code:

using (ServiceReferenceClient.TestServiceClient tc = new ServiceReferenceClient.TestServiceClient())
{
    tc.ClientCredentials.ServiceCertificate.Authentication.CertificateValidationMode = X509CertificateValidationMode.None;
    tc.ClientCredentials.UserName.UserName = "User1";
    tc.ClientCredentials.UserName.Password = "Pwd1";
    tc.ServiceMethod(param1, param2, param3);
}

It works fine but I need to see the actual SOAP request sent to the WCF service and response. How can I do that from my client?

I know I might have to write my own custom message inspector and would like some pointers on how to build one

回答1:

The options mentioned in the comments above are good for testing. If you want something more robust that you can include in your code, then I think what you want to implement is a WCF Message Inspector.

More on how to do this on the client:

You can inspect or modify the incoming or outgoing messages across a WCF client by implementing a System.ServiceModel.Dispatcher.IClientMessageInspector and inserting it into the client runtime.
