有關WCF奇怪的錯誤 - System.ServiceModel.CommunicationException了未處理

Question

我創建了一個簡單的WCF演示： 服務器端：

namespace ServerSide 
{ 
    class Program 
    { 
     static void Main(string[] args) 
     { 
      System.ServiceModel.ServiceHost host = 
       new System.ServiceModel.ServiceHost(typeof(HelloIndigo.HelloIndigoService), new Uri("http://locahost:8000/HelloIndigo")); 
      host.AddServiceEndpoint(typeof(HelloIndigo.IHelloIndigoService), new System.ServiceModel.BasicHttpBinding(), "HelloIndigoService"); 
      host.Open(); 

      Console.Write("Terminate Server"); 
      Console.ReadLine(); 
     } 
    } 
} 

客戶端：

namespace ClientSide 
    { 
     class Program 
     { 
      static void Main(string[] args) 
      { 
       System.ServiceModel.EndpointAddress ep = 
        new System.ServiceModel.EndpointAddress("http://locahost:8000/HelloIndigo/HelloIndigoService"); 
       IHelloIndigoService proxy = 
        System.ServiceModel.ChannelFactory<IHelloIndigoService>.CreateChannel(new System.ServiceModel.BasicHttpBinding(), ep); 
       string s = proxy.HelloIndigo(); 
       Console.WriteLine(s); 
       Console.ReadLine(); 
      } 
     } 
    } 

然後，運行ServerSide，當我嘗試運行CLientSide時，出現以下錯誤消息： 發生錯誤接收對http://locahost:8000/HelloIndigo/HelloIndigoService的HTTP響應。這可能是由於服務端點綁定不使用HTTP協議。這也可能是由於HTTP請求上下文被服務器中止（可能是由於服務關閉）。查看服務器日誌獲取更多詳細信

和錯誤的詳細信息：

System.ServiceModel.CommunicationException was unhandled 
     Message="An error occurred while receiving the HTTP response to http://locahost:8000/HelloIndigo/HelloIndigoService. This could be due to the service endpoint binding not using the HTTP protocol. This could also be due to an HTTP request context being aborted by the server (possibly due to the service shutting down). See server logs for more details."

是您的機器稱爲locahost？通常情況下，這些機器被稱爲LOCA升主機 - 那麼試試這個網址爲您服務（包括服務器和客戶端）：

new Uri("http://localhost:8000/HelloIndigo") 

隨着這一變化，我可以沒有任何重新創建您的樣品無論如何。
