WCF - Passing CurrentPrincipal in the Header
- by David Ward
I have a WCF service that needs to know the Principal of the calling user.
In the constructor of the service I have:
Principal = OperationContext.Current.IncomingMessageHeaders.GetHeader<MyPrincipal>("myPrincipal", "ns");
and in the calling code I have something like:
using (var factory = new ChannelFactory<IMyService>(localBinding, endpoint))
{
var proxy = factory.CreateChannel();
using (var scope = new OperationContextScope((IContextChannel)proxy))
{
var customHeader = MessageHeader.CreateHeader("myPrincipal", "ns", Thread.CurrentPrincipal);
OperationContext.Current.OutgoingMessageHeaders.Add(customHeader);
newList = proxy.CreateList();
}
}
This all works fine.
My question is, how can I avoid having to wrap all proxy method calls in the using (var scope...{ [create header and add to OperationContext]?
Could I create a custom ChannelFactory that will handle adding the myPrincipal header to the operation context? Something like that would save a whole load of copy/paste which I'd rather not do but I'm not sure how to achieve it:)
Thanks
