WCF配置在本地主机上工作,而不是在共享网站上

wcf asp.net

共享托管网站 ,我得到一个例外:

我不能改变,因为这是一个共享的环境。

Web.config 关于服务?我得到的是:

<system.serviceModel>
  <services>
    <service name="BoggleService">
      <endpoint binding="webHttpBinding" contract="Solver" behaviorConfiguration="webHttp"/>
    </service>
  </services>
  <behaviors>
    <endpointBehaviors>
      <behavior name="webHttp">
        <webHttp/>
      </behavior>
    </endpointBehaviors>
  </behaviors>
</system.serviceModel>

我也有这个配置,但是它被注释掉了(就像我说的,一个很久以前的项目,试图恢复它):

<serviceHostingEnvironment>
  <baseAddressPrefixFilters>
    <add prefix="http://www.example.com/"/>
  </baseAddressPrefixFilters>
</serviceHostingEnvironment>

二者都

索引超出范围。必须为非负且小于集合的大小。

下面是完整的堆栈跟踪:

[ArgumentOutOfRangeException: Index was out of range. Must be non-negative and less than the size of the collection.
Parameter name: index]
   System.ThrowHelper.ThrowArgumentOutOfRangeException(ExceptionArgument argument, ExceptionResource resource) +64
   System.ThrowHelper.ThrowArgumentOutOfRangeException() +15
   System.Collections.Generic.List`1.get_Item(Int32 index) +7515544
   System.ServiceModel.Web.WebServiceHost.AddAutomaticWebHttpBindingEndpoints(ServiceHost host, IDictionary`2 implementedContracts, String multipleContractsErrorMessage) +82
   System.ServiceModel.Web.WebServiceHost.OnOpening() +203
   System.ServiceModel.Channels.CommunicationObject.Open(TimeSpan timeout) +229
   System.ServiceModel.HostingManager.ActivateService(String normalizedVirtualPath) +121
   System.ServiceModel.HostingManager.EnsureServiceAvailable(String normalizedVirtualPath) +479

[ServiceActivationException: The service '/Solver.svc' cannot be activated due to an exception during compilation.  The exception message is: Index was out of range. Must be non-negative and less than the size of the collection.
Parameter name: index.]
   System.ServiceModel.AsyncResult.End(IAsyncResult result) +11667006
   System.ServiceModel.Activation.HostedHttpRequestAsyncResult.End(IAsyncResult result) +194
   System.ServiceModel.Activation.HostedHttpRequestAsyncResult.ExecuteSynchronous(HttpApplication context, Boolean flowContext) +176
   System.ServiceModel.Activation.HttpModule.ProcessRequest(Object sender, EventArgs e) +275
   System.Web.SyncEventExecutionStep.System.Web.HttpApplication.IExecutionStep.Execute() +68
   System.Web.HttpApplication.ExecuteStep(IExecutionStep step, Boolean& completedSynchronously) +75

这是来自WCF的内部——它不是来自我的代码(堆栈跟踪显示它永远不会到达我的代码,如果我运行调试器并在代码中设置断点,它永远不会到达)。

<baseAddressPrefixFilters> 设置为 http://localhost

谢谢!

我认为这个问题可以简化,因为它使用WebHttpBinding来托管Restful风格的服务。
在。网4.5,我们可以使用以下简化配置来托管Restful样式的服务。

  <system.serviceModel>
    <behaviors>
      <serviceBehaviors>
        <behavior>
          <serviceMetadata httpsGetEnabled="true" httpGetEnabled="true" />
          <serviceDebug includeExceptionDetailInFaults="true" />
        </behavior>
      </serviceBehaviors>
      <endpointBehaviors>
        <behavior>
          <webHttp />
        </behavior>
      </endpointBehaviors>
    </behaviors>
    <protocolMapping>
      <add binding="webHttpBinding" scheme="http" />
    </protocolMapping>
    <serviceHostingEnvironment aspNetCompatibilityEnabled="true" multipleSiteBindingsEnabled="true" />
  </system.serviceModel>

默认情况下,webhttpbinding使用WebHttpSecurityMode.None。因此,上面的身份验证架构错误不太可能发生。如果需要,不要忘记在IIS身份验证模块中启用身份验证模式。
尝试用我的配置替换您的配置,并在IIS站点绑定模块中提供http绑定。
