我有一个配置了传输安全性和基本 clientCredentialType 的 Web 服务客户端。该服务正在使用 HTTPS 端点，我很难诊断错误。我试图向存储请求和响应消息以及传递的凭据（至少是用户名）的应用程序添加一个日志。
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 中是否有任何扩展点可以做到这一点？还有什么建议吗？
谢谢
编辑：我得到的错误是这样的：

它是一个在 DEV 中正常工作但在 QA 中引发此错误的 Web 应用程序。代码相同，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>
