Get the domain name of a WCF request? - wcf

Question

How can I obtain the domain name or full URL of the requester?

Answer 1

I'm not sure that I understand your question, but if you need the domain name of the Windows user making the call to a service operation, use this:
OperationContext.Current.ServiceSecurityContext.PrimaryIdentity.Name
This will return "{domain}\{username}".
Try this and let me know what you think (you'll probably want to paste this code into an mstest project):
[TestClass]
public class AlternativeCredentials
{
// Contracts
[ServiceContract]
interface IMyContract
{
[OperationContract]
string GetUserName();
}
// Service
[ServiceBehavior(IncludeExceptionDetailInFaults = true)]
class MyService : IMyContract
{
public string GetUserName()
{
return OperationContext.Current.ServiceSecurityContext.PrimaryIdentity.Name;
}
}
// Client
class MyContractClient : ClientBase<IMyContract>, IMyContract
{
public MyContractClient() { }
public MyContractClient(Binding binding, string address) :
base(binding, new EndpointAddress(address)) { }
public string GetUserName()
{ return Channel.GetUserName(); }
}
#region Host
static string address = "net.tcp://localhost:8001/" + Guid.NewGuid().ToString();
static ServiceHost host;
[ClassInitialize()]
public static void MyClassInitialize(TestContext testContext)
{
host = new ServiceHost(typeof(MyService));
host.AddServiceEndpoint(typeof(IMyContract), new NetTcpBinding(), address);
host.Open();
}
[ClassCleanup()]
public static void MyClassCleanup()
{
if (host.State == CommunicationState.Opened)
host.Close();
}
#endregion
[TestMethod]
public void UseUserNameCredentials()
{
using (MyContractClient proxy =
new MyContractClient(new NetTcpBinding(), address))
{
proxy.ClientCredentials.UserName.UserName = "MyUsername";
proxy.ClientCredentials.UserName.Password = "MyPassword";
proxy.Open();
Assert.AreEqual("EMS\\magood", proxy.GetUserName());
proxy.Close();
}
}
}
