.NET Core 发布到 IIS - HTTP 错误 502.3 - 错误网关 - 指定的 CGI 应用程序遇到错误，服务器终止了进程

Question

我正在尝试将我从 RC2 升级到 RTM 的 .NET Core ASP.NET 网站发布到 IIS。

作为健全性检查，我成功地从 Visual Studio 2015 发布了模板/示例“ASP.NET Core Web 应用程序 (.NET Framework)”应用。

但由于某种原因，在发布 RTM 升级的应用程序时，我收到 HTTP 错误 502.3 - 错误网关 指定的 CGI 应用程序遇到错误，服务器终止了该进程。

该站点可以在 Visual Studio 中运行 IIS Express。

我该如何调试这个？大家有什么想法吗？

如果您长时间运行任务，并且网络浏览器在 2 分钟(默认请求时间)内未收到响应，您将收到此错误。因为超时后，IIS 会替换应用程序以“Bad Gateway”响应客户端。

也许您应该更改 web.config 中的请求时间。

在 system.webServer/aspNetCore 部分中设置 requestTimeout 属性，以指定 ASP.NET Core 模块等待监听 % 的进程响应的持续时间ASPNETCORE_PORT%。

• requestTimeout 必须仅以整分钟指定，否则默认为 2 分钟。

就像这样:

<system.webServer>
  <aspNetCore requestTimeout="00:20:00" ... />
</system.webServer>
