azure - 如何在 IIS 上托管 BOT Framework V4 BOT

Question

我在 IIS 上托管我的 BOT Framework V4 BOT。服务器配置如下

1. Windows Server 2012 R2
2. IIS 8.5

我还安装了 dotnet-hosting-2.2.1-win.exe，这是托管 BOT V4 所必需的。我已将应用程序池设置为“无托管代码”。我已经设置了 Startup.cs 文件所在文件夹的路径。另请查找 BOT 生成的日志附件。尽管如此，它仍然不起作用，错误如下

HTTP 错误 403.14 - 禁止Web 服务器配置为不列出该目录的内容。

Detailed Error Information:

Physical Path      ProjectPath

下面是web.config代码

<?xml version="1.0" encoding="utf-8"?>
<configuration>
  <location path="." inheritInChildApplications="false">
    <system.webServer>
      <handlers>
        <add name="aspNetCore" path="*" verb="*" modules="AspNetCoreModule" resourceType="Unspecified" />
      </handlers>
      <aspNetCore processPath="dotnet" arguments=".\ConfRoom.dll" stdoutLogEnabled="true" stdoutLogFile=".\logs\stdout" />
    </system.webServer>
  </location>
  <system.net>
     <defaultProxy useDefaultCredentials="false">
        <proxy usesystemdefault="False" proxyaddress="http://xx.xxx.xx.xxx:8080" bypassonlocal="True" />
      </defaultProxy>
  </system.net>
</configuration>

以下是BOT生成的日志

请帮忙。谢谢。

Answer 1

我认为 Drew Marsh 在他的回复中发现了问题，这可能是 web.config 问题。

如果您要在 IIS 中托管 .net core 应用程序，IIS 仍需要应用程序目录中的 web.config，该目录至少具有处理程序映射和 aspNetCore 路径。

基本上，IIS 必须知道该应用程序是 .net core 应用程序以及要运行的代码。

我可能是错的，但这看起来像是将所有内容都视为静态文件。

I get this error if I remove the web.config from a working .net core app hosted in IIS.

看起来与你的错误几乎相同，我也犯了类似的错误。

我通常很幸运地将我的项目发布为 IIS Web 部署包。这往往会创建所有必要的位。

工作的 web.confg 可能看起来像这样。

<configuration>
      <system.webServer>
        <handlers>
          <add name="aspNetCore" path="*" verb="*" modules="AspNetCoreModule" resourceType="Unspecified" />
        </handlers>
        <aspNetCore processPath="dotnet" arguments=".\blagh.dll" stdoutLogEnabled="false" stdoutLogFile=".\logs\stdout" />
      </system.webServer>
</configuration>
