Question

我正在尝试创建一个返回JSON对象的WCF服务。我的第一个问题是我没有看到服务方法暴露甚至调用它。当我这样调用服务方法时......“http：// localhost：60090 / VehicleDataService / detailbydivision？divisionId = 1＆amp; year = 2012”，我收到404错误。

... Web.Config中

    <system.serviceModel>
    <services>
      <service name="GMEOG.VehicleDataService" behaviorConfiguration="metadataBehavior">
        <endpoint address="" binding="webHttpBinding" contract="GMEOG.IVehicleDataService" behaviorConfiguration="VehicleDataServiceBehavior">
          <identity>
            <dns value="" />
          </identity>
        </endpoint>
        <endpoint address="mex" binding="mexHttpBinding" contract="IMetadataExchange"/>
      </service>
    </services>

    <behaviors>
      <serviceBehaviors>
        <behavior name="metadataBehavior">
          <!-- To avoid disclosing metadata information, set the value below to false and remove the metadata endpoint above before deployment -->
          <serviceMetadata httpGetEnabled="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="VehicleDataServiceBehavior">
          <webHttp helpEnabled="true" defaultOutgoingResponseFormat="Json" />
        </behavior>
      </endpointBehaviors>
    </behaviors>

    <serviceHostingEnvironment multipleSiteBindingsEnabled="true" />

  </system.serviceModel>
 <system.webServer>
   <modules runAllManagedModulesForAllRequests="true"/>
  </system.webServer>

这是我的界面......

[ServiceContract(Namespace = "GMEOG.VehicleDataService", Name = "VehicleDataService")]
public interface IVehicleDataService

{
[OperationContract]
[WebInvoke(Method = "GET",
           ResponseFormat = WebMessageFormat.Json,
           RequestFormat = WebMessageFormat.Json,
           BodyStyle = WebMessageBodyStyle.WrappedResponse,
           UriTemplate = "DetailByDivision?divisionId={divisionId}&year={year}")]
[return: MessageParameter(Name = "Vehicle")]
List<Vehicle> DetailByDivision(string divisionId, string year);


}

Answer 1

您是如何定义服务文件的？使用.svc文件或使用路由？

如果是前者（假设svc文件名为“VehicleDataService.svc”），则地址应为http://localhost:60090/VehicleDataService .svc /detailbydivision?divisionId=1&year=2012。

如果是后者，请更新您的帖子如何使用路由服务。

如果还有别的，请说明问题。

Answer 2

尝试在web.config中将主机添加到服务端点：

<host>
  <baseAddresses>
    <add baseAddress="http://localhost:60090/VehicleDataService" />
  </baseAddresses>
</host>
