WebAPI找不到WCF端點元素

Question

我正在嘗試通過.Net 4.5 C＃MVC4 WebAPI（RCWindsExtSvc）消耗可用的C＃WCF服務（RCWindsSvc）。 從WebAPI調用WCF服務時，我收到以下運行時錯誤：

在ServiceModel客戶端配置部分中，“找不到名稱為'RCWindsSvcEndpoint'的端點元素，並簽訂了RCWindsSvc.IService1合同”。 這可能是因為找不到您的應用程序的配置文件，或者是因為在客戶端元素中找不到與該名稱匹配的端點元素。

WCF服務中來自web.config的system.serviceModel為：

 <system.serviceModel>
  <services>
    <service name="RCWindsSvc.Service1" behaviorConfiguration="RCWindsSvc.Service1Behavior">
      <endpoint address="http://localhost:15021/RCWinds.svc"
          binding="webHttpBinding"
          contract="RCWindsSvc.IService1"
          behaviorConfiguration="ServiceAspNetAjaxBehavior"
          name="RCWindsSvcEndpoint"/>
      <!-- behaviorConfiguration="WebBehaviour" /> -->
    </service>
  </services>
  <behaviors>
    <serviceBehaviors>
      <behavior name="RCWindsSvc.Service1Behavior">
        <!-- 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="false"/>
      </behavior>
    </serviceBehaviors>
    <endpointBehaviors>
      <!-- <behavior name="webBehaviour">
        <webHttp/>
      </behavior>-->
      <behavior name="ServiceAspNetAjaxBehavior">
        <enableWebScript/>
      </behavior>
    </endpointBehaviors>
  </behaviors>
  <serviceHostingEnvironment aspNetCompatibilityEnabled="true" multipleSiteBindingsEnabled="false" />
</system.serviceModel>

我在WebAPI代碼中使用ConfigurationChannelFactory檢索WCF配置數據，以下是來自WebAPI控制器的代碼：

public String[] GetStationNames()
        {
            ExeConfigurationFileMap fileMap = new ExeConfigurationFileMap();
            fileMap.ExeConfigFilename = "web.config";
            Configuration newConfiguration = ConfigurationManager.OpenMappedExeConfiguration(fileMap, ConfigurationUserLevel.None);

            ConfigurationChannelFactory<RCWindsSvc.IService1> factory1 = new
                ConfigurationChannelFactory<RCWindsSvc.IService1>("RCWindsSvcEndpoint", newConfiguration, new EndpointAddress("http://localhost:15021/RcWinds.svc"));
            RCWindsSvc.IService1 client1 = factory1.CreateChannel();

            IEnumerable<string> stationNames = client1.GetStationNames();
            return stationNames.ToArray();

        }

這似乎是一個非常普遍的問題，我已經探索了許多建議的解決方案，但無濟於事。 非常感謝您的協助。

您在配置文件中缺少客戶端部分。

<system.serviceModel>
        <bindings>
            ...
        </bindings>
        <client>
           <endpoint address="http://localhost:15021/RCWinds.svc"
               binding="webHttpBinding" 
               contract="RCWindsSvc.IService1" name="RCWindsSvcEndpoint" />
        </client>
    </system.serviceModel>
