RESTful WCF 服務返回“找不到資源”。 錯誤

[英]RESTful WCF Service returns “The resource cannot be found.” error

 原文  2011-05-23 21:36:56  7   1    c#/ .net/ wcf/ rest

問題描述

我有一個不起作用的 RESTful 服務。 當我在地址欄中輸入 URI 時，我收到此錯誤：

無法找到該資源。

描述：HTTP 404。您正在查找的資源（或其依賴項之一）可能已被刪除、更改名稱或暫時不可用。 請查看以下 URL 並確保拼寫正確。

請求的 URL：/VirtualRUS/Service1.svc/

我不知道為什么它不起作用。 我將我的代碼和 web.config 與一個工作示例進行了比較，但我找不到任何差異。

編輯：另外，如果我使用服務引用，我可以很好地使用該服務。 如果我導航到 URI，或者更重要的是，當我嘗試創建WebRequest時，它就不起作用。

有誰知道為什么這不起作用？

服務1.cs：

[ServiceContract]
public interface IService1
{
   [OperationContract]
   [WebGet(UriTemplate = "/")]
   string Test(); 
}

服務1.svc.cs：

[ServiceBehavior(InstanceContextMode = InstanceContextMode.PerCall)]
public class Service1 : IService1
{
   public string Test()
   {
      return "It works!!";
   }
}

您的端點不是 REST 端點，而是“正常” SOAP 端點（二進制編碼/ http 傳輸）。 REST 端點是使用特定綁定 (webHttpBinding) 和行為 (webHttp) 定義的。 此外，添加服務參考不適用於 REST 端點，這也表明如果它適用於您，那么您沒有使用 REST 端點。

要將您的端點更改為 RESTful，您可以更改 web.config，如下所示（它實際上添加了一個 REST 端點，除了 SOAP 端點）。

<system.serviceModel>
    <services>
        <service name="ResearchUploadService.Service1" behaviorConfiguration="ResearchUploadService.Service1Behavior">
            <!-- Service Endpoints -->

        <endpoint address="customBinding" binding="customBinding" bindingConfiguration="basicConfig" contract="ResearchUploadService.IService1"/>
        <endpoint address="" binding="webHttpBinding" behaviorConfiguration="REST" contract="ResearchUploadService.IService1"/>
        </service>
    </services>
    <behaviors>
        <serviceBehaviors>
            <behavior name="ResearchUploadService.Service1Behavior">

                <serviceMetadata httpGetEnabled="true"/>
                <serviceDebug includeExceptionDetailInFaults="true"/>
            </behavior>
        </serviceBehaviors>
        <endpointBehaviors>
           <behavior name="REST">
             <webHttp/>
           </behavior>
        </endpointBehaviors>
  </behaviors>
  <bindings>
     <customBinding>
        <binding name="basicConfig">
           <binaryMessageEncoding/>
           <httpTransport transferMode="Streamed" maxReceivedMessageSize="67108864"/>
        </binding>
     </customBinding>

  </bindings>
</system.serviceModel>
