Force WCF to call a method on every request before entering actual function

Question

I have a RESTful WCF service with many different functions. For each function I need to call an authentication method that I have written. I can manually call this method on every request but I was looking for a way to force the WCF engine to call this method before these functions are entered. Does anyone know if this is possible?

Cheers

Answer 1

You could use the "Custom Behavior" approach.

You would need to write a Class that implements IDispatchMessageInspector. The following MSDN magazine article gives a nice explanation of this: Extending WCF with Custom Behaviors (link points to Wayback Machine cached copy; downloads likely don't work).

Answer 2

To force WCF REST Service to first call a method especially if it's for authorization customize/override CheckAccessCore method of System.ServiceModel.ServiceAuthorizationManager refer: http://msdn.microsoft.com/en-us/library/ms731774(v=vs.110).aspx
