WCF - 如何正確配置MVC客戶端使用WCF服務？

我完全知道這個問題已經被討論了很多次，但是這是我的項目的一個特定配置，我很想掌握哪些使我的服務 - 客戶端通信出錯。我在這件事上請求你的幫助。請原諒我的愚蠢錯誤，我對WCF和REST服務一般都很陌生。WCF - 如何正確配置MVC客戶端使用WCF服務？

所以，基本上，我想創建一個MVC應用程序，它將使用託管在IIS服務器上的WCF REST服務。

我已經創建了一個WCF服務應用程序具有以下服務合同：

[ServiceContract] 
public interface IUserService 
{ 
    [OperationContract] 
    [WebInvoke(Method = "GET", 
     ResponseFormat = WebMessageFormat.Json, 
     RequestFormat = WebMessageFormat.Json, 
     BodyStyle = WebMessageBodyStyle.Wrapped, 
     UriTemplate = "/ListaUtilizatori/")] 
    DataSet ListaUtilizatori(); 

    [OperationContract] 
    [WebInvoke(Method = "GET", 
     ResponseFormat = WebMessageFormat.Json, 
     RequestFormat = WebMessageFormat.Json, 
     BodyStyle = WebMessageBodyStyle.Wrapped, 
     UriTemplate = "/DetaliiUtilizator/{id}")] 
    DataSet DetaliiUtilizator(String id); 


    [OperationContract] 
    [WebInvoke(Method = "POST", 
     ResponseFormat = WebMessageFormat.Json, 
     RequestFormat = WebMessageFormat.Json, 
     BodyStyle = WebMessageBodyStyle.Wrapped, 
     UriTemplate = "/AdaugaUtilizator")] 
    String AdaugaUtilizator(Utilizator utilizator); 

    [OperationContract] 
    [WebInvoke(Method = "PUT", 
     RequestFormat = WebMessageFormat.Json, 
     ResponseFormat = WebMessageFormat.Json, 
     UriTemplate = "/ActualizeazaUtilizator")] 
    String ActualizeazaUtilizator(Utilizator utilizator); 

    [OperationContract] 
    [WebInvoke(Method = "DELETE", 
     RequestFormat = WebMessageFormat.Json, 
     ResponseFormat = WebMessageFormat.Json, 
     UriTemplate = "/StergeUtilizator/{id}")] 
    String StergeUtilizator(String id); 
}

我正確實現的方法和在web.config文件I配置的服務模型爲這樣：

<system.serviceModel> 
    <services> 
     <service name="RESTService.UserService" behaviorConfiguration="RESTServiceBehaviour"> 
     <endpoint address="" binding="webHttpBinding" bindingConfiguration="WebHttpBinding_IUserService" contract="RESTService.IUserService" behaviorConfiguration="RESTEndpointBehavior"></endpoint> 
     </service> 
    </services> 
    <behaviors> 
     <serviceBehaviors>   
     <behavior name="RESTServiceBehaviour"> 
      <!-- To avoid disclosing metadata information, set the values below to false before deployment --> 
      <serviceMetadata httpGetEnabled="true" httpsGetEnabled="true"/> 
      <!-- To receive exception details in faults for debugging purposes, set the value below to true. Set to false before deployment to avoid disclosing exception information --> 
      <serviceDebug includeExceptionDetailInFaults="true"/> 
     </behavior> 
     </serviceBehaviors> 
     <endpointBehaviors> 
     <behavior name="RESTEndpointBehavior"> 
      <webHttp helpEnabled="True"/> 
     </behavior> 
     </endpointBehaviors> 
    </behaviors> 
    <bindings> 
     <webHttpBinding> 
     <binding name="WebHttpBinding_IUserService" /> 
     </webHttpBinding> 
    </bindings> 
    <protocolMapping> 
     <add binding="webHttpBinding" scheme="http" /> 
    </protocolMapping>  
    <serviceHostingEnvironment aspNetCompatibilityEnabled="true" multipleSiteBindingsEnabled="true" /> 
    </system.serviceModel>

之後，我在IIS服務器上發佈了WCF App，它在瀏覽器中正常返回預期的JSON格式響應。

我創建了一個MVC應用程序，我向其添加了對發佈的WCF服務的服務引用，並將其命名爲UserServiceReference。奇怪的是，沒有system.serviceModel節點加入或在MVC的web.config配置，所以手動添加了以下內容：

<system.serviceModel> 
    <behaviors> 
     <endpointBehaviors> 
     <behavior name="RESTEndpoint"> 
      <webHttp helpEnabled="true"/> 
     </behavior> 
     </endpointBehaviors> 
    </behaviors> 
    <bindings> 
     <webHttpBinding> 
     <binding name="WebHttpBinding_IUserService" />   
     </webHttpBinding>  
    </bindings> 
    <client> 
     <endpoint address="http://localhost/RESTUserService/UserService.svc" binding="webHttpBinding" bindingConfiguration="WebHttpBinding_IUserService" 
       behaviorConfiguration="RESTEndpoint" contract="UserServiceReference.IUserService" name="WebHttpBinding_IUserService" /> 
    </client> 
</system.serviceModel>

然後我試圖通過在應用程序的用下面的代碼控制器之一創建客戶機來測試功能：

UserServiceReference.UserServiceClient client = new UserServiceReference.UserServiceClient(); 
      DataSet ds = client.DetaliiUtilizator("2"); 
UserServiceReference.UserDataContractUtilizator utilizator = new UserServiceReference.UserDataContractUtilizator();

當我運行我的應用程序我得到這個錯誤在瀏覽器：

[WebException: The remote server returned an error: (404) Not Found.] System.Net.HttpWebRequest.GetResponse() +1390 System.ServiceModel.Channels.HttpChannelRequest.WaitForReply(TimeSpan timeout) +55 

[EndpointNotFoundException: There was no endpoint listening at http://localhost/RESTUserService/UserService.svc/DetaliiUtilizator that could accept the message. This is often caused by an incorrect address or SOAP action. See InnerException, if present, for more details.]

我說這些東西作爲編譯Ø f我讀過的所有帖子。它必須是所有代碼中的某個錯誤。會是什麼呢？

非常感謝！

從錯誤：'查看InnerException，如果存在，獲取更多詳細信息。' –

@JamieR我添加了整個異常。 – Ionna

您確定'http：// localhost/RESTUserService/UserService.svc/DetaliiUtilizator'是否是正確的端點？ –

我已經最終意識到該問題是在這篇文章中：

https://blogs.msdn.microsoft.com/carlosfigueira/2012/03/25/mixing-add-service-reference-and-wcf-web-http-a-k-a-rest-endpoint-does-not-work/

好像使用WebHttpBinding將導致無用的自動生成的客戶端代碼添加服務引用WCF服務與端點。
