记录传递给WCF Web服务的凭据

Question

我有一个配置了传输安全性和基本clientCredentialType的Web服务客户端。 该服务使用的是HTTPS端点，我很难诊断错误。 我试图将日志添加到存储请求和响应消息以及传递的凭据（至少是用户名）的应用程序中。
对于消息，我添加了带有MessageInspector的自定义行为。
我如何也可以记录凭据？ WCF中是否有扩展点可以做到这一点？ 还有其他建议吗？
谢谢

编辑：我得到的错误是这样的：

[NotSupportedException: This method is not supported by this class.]
System.Net.BasicClient.Lookup(HttpWebRequest httpWebRequest, ICredentials credentials) +2544984

它是一个Web应用程序，可以在DEV中正常运行，但是会在质量检查中引发此错误。 代码相同，并且用户在两种环境中均有效。

绑定配置为：

<binding name="CommonBinding" maxReceivedMessageSize="10000000" useDefaultWebProxy="true" openTimeout="00:10:00" sendTimeout="00:10:00">
      <security mode="Transport">
        <transport clientCredentialType="Basic" proxyCredentialType="Basic"
          realm="" />
        <message clientCredentialType="UserName" algorithmSuite="Default" />
      </security>
</binding>

我相信您可以在IAuthorizationPolicy中执行此操作
