IDispatchMessageInspector 不工作 WCF 服务

Question

我有工作的 WCF 服务，我需要在其中添加一些有关授权的功能。我创建了继承自 ServiceAuthorizationManager 的 class，并成功将其添加到 app.config 中。一切正常。

我还需要实现 class，后者实现了 IDispatchMessageInspector，因此我可以进行一些消息验证。

我遵循了很多例子，例如 this, this, this, this, this and some others. Also questions in SO like this。

它们在 app.config 文件中似乎都具有相同的配置。但是，当我尝试使用运行代码时，似乎 class 实现 IDispatchMessageInspector 在我调试时从未被调用。我添加了断点，但它们永远不会被击中。

我是不是遗漏了什么明显的东西？

<extensions>
  <behaviorExtensions>
    <add name="MessageInspectorBehaviourExtension" type="MultipleEndpoints.MessageInspectorBehaviourExtension, RL_Managed_Service" />
  </behaviorExtensions>
</extensions>
<behaviors>
<serviceBehaviors>
    <behavior name="RLServiceBehavior">
      <serviceDebug includeExceptionDetailInFaults="False"/>
      <serviceAuthorization serviceAuthorizationManagerType="MyProject.Services.AuthorizationService,MyProject"/>
      <MessageInspectorBehaviourExtension />
    </behavior>
  </serviceBehaviors>
</behaviors>
<services>
  <service behaviorConfiguration="RLServiceBehavior" name="MultipleEndpoints.RL_Managed_Service">
    <endpoint address="" binding="basicHttpBinding" contract="MultipleEndpoints.container_db_ops" bindingConfiguration="TransportSecurity"/>
    <endpoint address="mex" binding="mexHttpBinding" contract="IMetadataExchange"/>
    <host>
      <baseAddresses>
        <!--  --><add baseAddress="http://localhost:49224/My_Service/"/>
      </baseAddresses>
    </host>
  </service>
</services>

Answer 1

在您修复配置后，我想我知道原因了。您尝试将您的行为扩展注册为服务行为，而 IDispatchMessageInspector 应该在端点级别注册（如 link you mentioned - 请参阅那里的最后一个示例）。这是适合您的配置文件：

<extensions>
  <behaviorExtensions>
    <add name="MessageInspectorBehaviourExtension" type="MultipleEndpoints.MessageInspectorBehaviourExtension, RL_Managed_Service" />
  </behaviorExtensions>
</extensions>
<behaviors>
  <serviceBehaviors>
    <behavior name="RLServiceBehavior">
      <serviceDebug includeExceptionDetailInFaults="False"/>
      <serviceAuthorization serviceAuthorizationManagerType="MyProject.Services.AuthorizationService,MyProject"/>
    </behavior>
  </serviceBehaviors>
  <endpointBehaviors>
    <behavior name="RLEndpointBehavior">
      <MessageInspectorBehaviourExtension />
    </behavior>
  </endpointBehaviors>
</behaviors>
<services>
  <service behaviorConfiguration="RLServiceBehavior" name="MultipleEndpoints.RL_Managed_Service">
    <endpoint address="" binding="basicHttpBinding" behaviorConfiguration="RLEndpointBehavior" contract="MultipleEndpoints.container_db_ops" bindingConfiguration="TransportSecurity"/>
    <endpoint address="mex" binding="mexHttpBinding" contract="IMetadataExchange"/>
    <host>
      <baseAddresses>
        <!--  --><add baseAddress="http://localhost:49224/My_Service/"/>
      </baseAddresses>
    </host>
  </service>
</services>

Answer 2

我找到了另一种无需 app.config 即可注册 IDispatchMessageInspector 的方法。在“OnStart”方法中，您可以简单地遍历端点。

service = New ServiceHost(GetType(My_Service))

For Each endpoint In service.Description.Endpoints
    If Not endpoint.Contract.Name.Equals("IMetadataExchange") Then
        endpoint.EndpointBehaviors.Add(New MessageInspectorBehaviour)
    End If
Next
