.net - 使用 WCF 模拟和 net.tcp 绑定(bind)访问 web.config 设置

Question

我正在尝试对 IIS 7 中托管的 WCF 服务(使用 net.tcp 绑定(bind))使用模拟。我已经到了模拟客户端的地步，但每当我尝试访问 Web 中的任何配置设置时.config 使用 Settings.Default.SomeSetting 它会抛出 SettingsPropertyNotFoundException。这是因为 IIS 以与模拟身份不同的身份运行吗？如果是这样，我必须更改哪些设置以允许它们在相同的模拟身份下运行？我试过设置“servicePrincipalName”属性，但没有成功。

我在下面包含了我的 web.config 设置:

<system.serviceModel>
    <services>
      <service name="TestServices">
        <endpoint address="" binding="netTcpBinding" bindingConfiguration="tcpbinding"
          contract="Test.ITestService">
          <identity>
            <servicePrincipalName value="NT AUTHORITY\NETWORK SERVICE" />
          </identity>
        </endpoint>
        <endpoint address="mextcp" binding="mexTcpBinding" contract="IMetadataExchange" />
      </service>
    </services>        
    <serviceHostingEnvironment aspNetCompatibilityEnabled="true"/>
    <bindings>          
      <netTcpBinding>
        <binding name="tcpbinding" maxBufferSize="2147483647" maxReceivedMessageSize="2147483647" maxBufferPoolSize="2147483647" portSharingEnabled="true">
          <security mode="Transport">
            <transport clientCredentialType="Windows" protectionLevel="None"/>
            <message clientCredentialType="Windows"/>
          </security>
        </binding>
      </netTcpBinding>
    </bindings>

      <serviceBehaviors>
        <behavior>
          <!-- 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="true" />
          <serviceAuthorization impersonateCallerForAllOperations="true" />

      </serviceBehaviors>
    </behaviors>
  </system.serviceModel>

我似乎没有在服务器端正确模拟我的客户端，因为我需要将客户端上的 allowedImpersonationLevel 设置为“模拟”。这默认为“标识”。因此，当我使用 WindowsIdentity.GetCurrent().Name 进行测试时，我得到了正确的用户名，但实际上并未模拟该用户。

所以将它添加到我的客户端 web.config 中就可以了:

    <client>
      <endpoint address="net.tcp://localhost/Test/Service/TestService.svc"
          binding="netTcpBinding" bindingConfiguration="NetTcpBinding_ITestService"
          contract="ServiceReference.ITestService" name="NetTcpBinding_ITestService"
          behaviorConfiguration="ImpersonationBehavior">
      </endpoint>
    </client>
    <behaviors>
      <endpointBehaviors>
        <behavior name="ImpersonationBehavior">
          <clientCredentials>
            <windows allowedImpersonationLevel="Impersonation" />
          </clientCredentials>
        </behavior>
      </endpointBehaviors>
    </behaviors>
