Question

我有一个从Visual Studio 2017 Basic Azure Node.js Express Application生成的节点js express应用程序。我假设Azure部署所需的所有配置都在模板附带的Web.config文件中设置，但我在Azure发布后收到此错误：

iisnode在处理请求时遇到错误。   HRESULT：0x2 HTTP状态：500 HTTP subStatus：1002 HTTP原因：   内部服务器错误您收到此HTTP 200响应，因为   system.webServer/iisnode/@devErrorsEnabled配置设置为   ＆＃39;真＆＃39;

除了node.exe进程的stdout和stderr的日志之外，   考虑使用调试和ETW跟踪来进一步诊断   问题

node.exe进程尚未向stderr或   iisnode无法捕获此信息。经常的原因是   iisnode模块无法创建要捕获的日志文件   node.exe的stdout和stderr输出。请检查身份   运行node.js应用程序的IIS应用程序池已读取   并将访问权限写入服务器所在的目录   node.js应用程序位于。或者，您可以禁用日志记录   通过设置system.webServer/iisnode/@loggingEnabled元素   web.config到＆＃39; false＆＃39;。

如果我发布应用程序而不修改任何内容，它运行良好，但是当我添加静态文件并添加相关模块时，它开始给我上面的错误。下面是我的web.config文件

Answer 1

请确保您使用iisnode模块通过process.env.PORT环境变量提供的监听地址。见Nodejs application returns error: iisnode encountered an error when processing the request HRESULT: 0x2 HTTP status: 500 HTTP subStatus: 1002。

要进一步排除故障，您可以启用stdout和stderr流的日志记录。关于如何操作，请参阅How to debug a Node.js web app in Azure App Service。
