测试客户端 WCF 抛出错误 wjen 被调用

Question

我有 WCF 服务，我想测试它，当调用框出现并且我按下调用时，它会抛出一个错误，我用谷歌搜索了它，但到目前为止无法运行它，这里是我得到的错误：

实际错误信息：

Failed to invoke the service. Possible causes: The service is offline or inaccessible; the client-side configuration does not match the proxy; the existing proxy is invalid. Refer to the stack trace for more detail. You can try to recover by starting a new proxy, restoring to default configuration, or refreshing the service.

               at TurbineMonitorServiceClient.SetStatus(String turbineId, StatusChangeEventData stat

这是我在本地主机上运行的配置：

 <serviceBehaviors>
    <behavior>
      <!-- To avoid disclosing metadata information, set the value below to false and remove the metadata endpoint above before deployment -->
      <serviceMetadata httpGetEnabled="false" />
      <!-- 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>
</behaviors>
<services>
  <service name="TurbineMonitor.TurbineMonitor">
    <endpoint address="" behaviorConfiguration="REST" binding="webHttpBinding" contract="TurbineMonitor.ITurbineMonitorService" />
    <endpoint address="soap" binding="basicHttpBinding" contract="TurbineMonitor.ITurbineMonitorService" />
    <endpoint address="mex" binding="mexHttpBinding" contract="IMetadataExchange" />
  </service>
</services>

在配置文件中，我们发布的服务有两个ways.one是restful风格，一个是soap web service。需要注意的一点是，WCF测试客户端一般用于测试soap web服务，而不是restful风格的服务，后者通常由Postman软件进行测试。因此，我建议您检查是否正在测试由 Basichttpbinding 创建的 soap web 服务。

此外，由于错误详情表明该服务无法访问和离线，请检查 IISExpress 是否正常托管该服务。我们可以点击右下角的IISExpress图标，然后查看运行网站。
如果问题仍然存在，请随时告诉我。
