一种解决方法是调整您的 Web 服务器跟踪级别。例如,在 web.config 文件中添加以下设置可以解决问题,
<system.webServer>
<tracing>
<traceFailedRequests>
<remove path="*"/>
<add path="*">
<traceAreas>
<add provider="ASP" verbosity="Verbose" />
<!-- Note that the verbosity is set to Warning (default value is Verbose)-->
<add provider="ASPNET" areas="Infrastructure,Module,Page,AppServices" verbosity="Warning" />
<add provider="ISAPI Extension" verbosity="Verbose" />
<add provider="WWW Server" areas="Authentication,Security,Filter,StaticFile,CGI,Compression,Cache,RequestNotifications,Module,Rewrite,WebSocket" verbosity="Verbose" />
</traceAreas>
<failureDefinitions statusCodes="200-999" />
</add>
</traceFailedRequests>
</tracing>
</system.webServer>
