将面向 .Net Framework 4.62 的 .Net Core 应用程序部署到 Azure

Question

我们使用 .Net Core Web 模板在 VS 2017 中创建了一个应用程序。从那以后我们意识到我们实际上需要引用一些完整的框架包。

所以我们把目标框架改成了4.6.2。

但是，现在当 Web 应用程序部署到 azure 时，我一直收到错误消息：

HTTP 错误 502.5 - 进程失败 此问题的常见原因： 申请进程启动失败 应用程序进程开始但随后停止 应用程序进程已启动但未能侦听配置的端口 故障排除步骤： 检查系统事件日志中的错误消息 启用记录应用程序进程的标准输出消息 将调试器附加到应用程序进程并检查 欲了解更多信息，请访问：https://go.microsoft.com/fwlink/?LinkID=808681

它似乎甚至无法启动，但我不确定我需要进行哪些更改才能使其正常工作。

当我发布它时，会在服务器上创建一个 web.config 文件，其中包含以下内容：

<?xml version="1.0" encoding="UTF-8"?>
<configuration>
<!--ProjectGuid: db77cdb1-05c4-450e-94d8-5dabc48c6d76-->
<system.webServer>
<handlers>
<add resourceType="Unspecified" modules="AspNetCoreModule" verb="*" path="*" name="aspNetCore"/>
</handlers>
<aspNetCore stdoutLogFile=".\logs\stdout" stdoutLogEnabled="true" processPath=".\Genesis.IdentityServer.exe"/>
</system.webServer>
</configuration>

我启用了日志记录。

天蓝色调试控制台上的事件日志报错如下：

这让我很困惑，我不能简单地从我的 .net 核心应用程序中定位框架 462 吗？

编辑

我打开了详细错误，现在看到：

HTTP 错误 502.5 - 网关错误 指定的 CGI 应用程序遇到错误，服务器终止了进程。

最可能的原因： CGI 应用程序没有返回一组有效的 HTTP 错误。 由于父网关中的错误，充当代理或网关的服务器无法处理请求。

您可以尝试的事情： 使用 DebugDiag 对 CGI 应用程序进行故障排除。 确定代理或网关是否会导致此错误。

详细错误信息： 模块 AspNetCoreModule 通知 ExecuteRequestHandler 处理程序 aspNetCore 错误代码 0x00000000 请求的 URL http://GenIdentityServer:80/favicon.ico 物理路径 D:\home\site\wwwroot\favicon.ico 登录方法匿名 登录用户匿名

我在 WebHostBuilder().build 调用周围放了一个 try catch，这是记录的内容：

好吧，我没有意识到这已被添加到代码中：

//.UseWebListener(选项 => //{ // options.ListenerSettings.Authentication.Schemes = AuthenticationSchemes.Negotiate | AuthenticationSchemes.NTLM； // options.ListenerSettings.Authentication.AllowAnonymous = true; //})

这当然不适用于 azure！
