C# WCF REST安全模拟

我的网站在IIS7中设置为启用Windows身份验证

我的服务中有3个方法，2个方法需要Windows身份验证，1个不需要。不使用的是

[OperationBehavior(Impersonation = ImpersonationOption.Allowed)]

另外两个正在使用

[OperationBehavior(Impersonation = ImpersonationOption.Required)]

我的web.config看起来像：

<system.webServer>
<modules runAllManagedModulesForAllRequests="true">
  <add name="UrlRoutingModule" type="System.Web.Routing.UrlRoutingModule, System.Web, Version=4.0.0.0, Culture=neutral, PublicKeyToken=b03f5f7f11d50a3a" />
</modules>
<security>
  <authentication>
    <anonymousAuthentication enabled="true"/>
    <windowsAuthentication enabled="true" />
  </authentication>
</security>


 </system.webServer>
  <system.serviceModel>
    <serviceHostingEnvironment aspNetCompatibilityEnabled="true"/>
    <behaviors>
      <serviceBehaviors>
        <behavior>
          <dataContractSerializer maxItemsInObjectGraph="2147483647"/>
          <serviceAuthorization impersonateCallerForAllOperations="true"/>
        </behavior>
      </serviceBehaviors>
    </behaviors>
    <standardEndpoints>
      <webHttpEndpoint>
        <standardEndpoint name="" helpEnabled="true" automaticFormatSelectionEnabled="true" defaultOutgoingResponseFormat="Json" maxBufferPoolSize="2147483647"
                          maxBufferSize="2147483647" maxReceivedMessageSize="2147483647" transferMode="Streamed">
          <security mode="TransportCredentialOnly">
            <transport clientCredentialType="Windows" />
          </security>
        </standardEndpoint>
      </webHttpEndpoint>
    </standardEndpoints>
  </system.serviceModel>

当我运行并尝试执行设置为Allowed的方法时，我没有传递任何凭据，它会失败，并出现未经授权的错误。我缺少什么？

在使用时，您仍然需要提供凭据

[操作行为（模拟=模拟选项.允许）]

您是否尝试将ImpersonateCallerForAllOperations设置为false
