如何获取 Azure Web 应用程序的错误 500 的详细信息? [英] How do I get the details of an Error 500 for an Azure Web App?

问题描述

我有一个已部署为 Azure Web 应用程序的 MVC 6 站点.我已经使用服务器资源管理器在 Visual Studio 中启用了所有跟踪/诊断选项.我正在尝试进行远程调试，但我只在浏览器上看到错误 500，并没有找到任何关于错误发生位置的信息(或触发错误断点).

I have an MVC 6 site that has been deployed as an Azure Web App. I have enabled all tracing / diagnostic options in Visual Studio using Server Explorer. I am trying to do remote debugging, but I am only seeing an Error 500 on my browser, and not finding any information (or triggering an error breakpoint) on where exactly the error occurred.

我在从 Azure 获得的文件日志中找不到任何错误跟踪.

I can't find any error trace on the file logs that I get from Azure.

我应该如何解决 Azure Web 应用程序中的错误 500?

How should I troubleshoot Error 500's in an Azure Web App?

向 config.json 添加 "CustomErrors": {"Mode": "Off"} 无效.

Adding "CustomErrors": {"Mode": "Off"} to config.json didn't work.

推荐答案

对于 MVC 6，您需要将 web.config 文件添加到 wwwroot 文件夹，内容如下:

For MVC 6 you need to add a web.config file to the wwwroot folder with the following:

<configuration>
   <system.web>
      <customErrors mode="Off"/>
   </system.web>
</configuration>

这会将标记添加到已部署的 web.config 文件中，并为您提供详细的错误信息.请参阅 http://docs.asp.net/en/latest/fundamentals/diagnostics.html#http-500-errors-on-azure 了解更多详情.

That will add the markup to the deployed web.config file, and give you detailed errors. See http://docs.asp.net/en/latest/fundamentals/diagnostics.html#http-500-errors-on-azure for more details.
