在共享提供程序上托管WCF服务

Question

我正在尝试访问共享主机服务器上的WCF服务，我可以使用该服务，但当我尝试调用该服务时，我得到"调用者未通过服务验证"错误。

客户机app.config

<?xml version="1.0" encoding="utf-8" ?>
<configuration>
    <system.serviceModel>
        <bindings>
            <wsDualHttpBinding>

                    </security>
                </binding>
            </wsDualHttpBinding>
        </bindings>
        <client>
            <endpoint address="http://mmservice.somee.com/MMService.Ticketing.svc"
                binding="wsDualHttpBinding" bindingConfiguration="WSDualHttpBinding_TicketingService"
                contract="MMService.TicketingService" name="WSDualHttpBinding_TicketingService">
                <identity>
                    <servicePrincipalName value="host/vb5100" />
                </identity>
            </endpoint>
        </client>
    </system.serviceModel>
</configuration>

服务app.config

            <add baseAddress = "http://localhost:8732/Design_Time_Addresses/MMService/Service1/"/>
          </baseAddresses>
        </host>
        <endpoint address ="" binding="wsDualHttpBinding" bindingConfiguration="" contract="MMService.ITicketService">
        </endpoint>
        <endpoint address="mex" binding="mexHttpBinding" contract="IMetadataExchange"/>
      </service>
    </services>
    <behaviors>
      <serviceBehaviors>
        <behavior name="MMService.Service1Behavior">
          <serviceMetadata httpGetEnabled="True"/>
          <serviceDebug includeExceptionDetailInFaults="False" />
        </behavior>
      </serviceBehaviors>
    </behaviors>
  </system.serviceModel>
</configuration>

有人知道如何解决这个问题吗?谢谢。

我有相同的错误与我的WCF服务托管在IIS上的共享提供商。显然，WCF不支持部分可信的调用者。我的解决方案是在WCF服务的web配置文件的标签中添加信任声明。从那以后一切都很好。

<configuration>
  <system.web>
    <trust level="full"/>
    ...
  </system.web>
  ...
</configuration>
