Wcf get raw request from operation

Question

I've searched a lot for a good answer but got a lot of answers that didn't satisfy me.

We have a service with the usual operations. Inside each operation we call a different project to handle te operation and store some info of the operation inside a database.

We've got a new requirement: Store the soap message of the operation in the database too. Is it possible to receive the soap (xml) from the wcf operation? Or are event really needed?

Answer 1

I was unable to use OperationContext.Current.RequestContext.RequestMessage.ToString() because it translates the request into Xml. When the request is JSON, I'd prefer it stay that way. I also found that, by the time an endpoint's method is invoked, Request.InputStream is empty---even when I have <add key="wcf:serviceHostingEnvironment:useClassicReadEntityBodyMode" value="true" /> in web.config (FYI: the app is running .Net 4.5.2).

So, what I did was to implement Application_BeginRequest in Global.asax.cs. I extract the contents of Request.InputStream there, and save that request body to Context.Items. Later, in IErrorHandler's ProvideFault(...), I transfer the saved string over to the Exception's Data property so that the logging will later capture it when HandleError(...) runs (Items is empty by the time HandleError runs).

Answer 2

For myself i found this solution to get the raw soap message in framework 4.5:

OperationContext.Current.RequestContext.RequestMessage.ToString()
