在多个绑定上承载IIS站点时，如何获取正确的本地地址URI？

Question

I have configured a simple service in IIS with multiple port bindings. The current channel local address is always the same no matter which port was called.

.

[ServiceBehavior(InstanceContextMode = InstanceContextMode.Single)]
public class TestService : ITestService
{
  public string Test()
  {
    return OperationContext.Current.Channel.LocalAddress.Uri.Port.ToString();
  }
}

Call to testHost2:7772 -> returns 7772

Call to testHost1:7771 -> returns 7772 too

Answer 1

You could use this below code to get the hostname and the port using WCF:

var test = OperationContext.Current.Host.BaseAddresses[0].Authority;

or

Uri uri = OperationContext.Current.IncomingMessageHeaders.To ;
