c# - RESTful WCF 服务返回 "The resource cannot be found."错误

Question

我有一个无法运行的 RESTful 服务。当我在地址栏中键入 URI 时，收到此错误:

The resource cannot be found.

Description: HTTP 404. The resource you are looking for (or one of its dependencies) could have been removed, had its name changed, or is temporarily unavailable. Please review the following URL and make sure that it is spelled correctly.

Requested URL: /VirtualRUS/Service1.svc/

我不知道为什么它不起作用。我将我的代码和 web.config 与一个工作示例进行了比较，没有发现任何差异。

编辑:此外，如果我使用服务引用，我就可以很好地使用该服务。如果我导航到 URI，或者更重要的是，当我尝试创建 WebRequest 时，它就不起作用。

有谁知道为什么这行不通吗？

Service1.cs:

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

Service1.svc.cs:

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

Web.Config:

Answer 1

您的端点不是 REST 端点，而是“普通”SOAP 端点(二进制编码/http 传输)。 REST 端点是使用特定绑定(bind) (webHttpBinding) 和行为 (webHttp) 定义的。此外，添加服务引用不适用于 REST 端点，这也表明如果它适用于您，则您没有使用 REST 端点。

要将您的端点更改为 RESTful，您可以更改 web.config，如下所示(除了您已有的 SOAP 端点之外，它实际上添加了一个 REST 端点)。

<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>
