可能有相同的合同，相同的绑定，相同的地址，但不同的端口？

Question

我有需要通过basicHTTPBinding进行通信的手持设备。我有一个合同，一切都按照广告的方式工作。

我需要扩展它以轻松支持更改为测试环境，培训和课程生产。我采取了端口路由，认为我可以暴露不同端点的端口差异，并根据端口决定我想从哪个数据库获取信息。

我似乎无法完成这项工作，到目前为止没有发现任何信息表明它可以完成。由于端口是可选的，它可能不是。

有人做过类似的事情吗？

虽然你不能做你想要的端口，你可以用不同的路径来完成。如将“/ prod”或“/ test”附加到您的基地址。我已经包含了一个例子来说明这一点。

using System; 
using System.Collections.Generic; 
using System.Collections.ObjectModel; 
using System.ServiceModel; 
using System.ServiceModel.Description; 

namespace WCFTest 
{ 
    class Program 
    { 
     static void Main() 
     { 
      List<Uri> baseAddresses = new List<Uri> { new Uri("http://localhost:1000/Prod"), new Uri("http://localhost:1000/Test") }; 
      ServiceHost wcfHost = new ServiceHost(typeof(SimpleWCF), new Uri[] {new Uri("http://localhost:1000")}); 

      foreach (ServiceEndpoint endpoint in SimpleWCF.CreateEndpoints(baseAddresses.ToArray())) 
      { 
       wcfHost.AddServiceEndpoint(endpoint); 
      } 

      ServiceMetadataBehavior metadataBehavior = new ServiceMetadataBehavior(); 
      metadataBehavior.HttpGetEnabled = true; 
      wcfHost.Description.Behaviors.Add(metadataBehavior); 

      wcfHost.Open(); 
      Console.ReadLine(); 
      wcfHost.Close(); 
     } 
    } 

    [ServiceContract] 
    public interface ISimpleWCF 
    { 
     [OperationContract] 
     string TestMethod(); 
    } 

    public class SimpleWCF : ISimpleWCF

     public SimpleWCF()

      this.Contract = ContractDescription.GetContract(typeof(ISimpleWCF), GetType()); 
     } 

     /// <summary>

        return _current; 
       } 

       lock (_syncRoot) 
       { 
        if (_current == null) 
         _current = new SimpleWCF(); 

       } 

       return _current; 
      } 
     }

       BasicHttpBinding endpointBinding = new BasicHttpBinding(securityMode); 

       ServiceEndpoint endpoint = new ServiceEndpoint(Current.Contract, endpointBinding, address); 
       endpoint.ListenUriMode = ListenUriMode.Explicit; 
       endpointCollection.Add(endpoint); 
      } 

      return endpointCollection; 
     } 

     #region ISimpleWCF Members 

     string ISimpleWCF.TestMethod() 
     { 
      if (OperationContext.Current.Channel.LocalAddress.Uri.AbsoluteUri.EndsWith("Prod")) 
       return "Hello Prod!"; 
      else return "Hello Test!"; 
     }
