在 IIS 上托管 rc1-final-update1 的问题

Question

当我从 Visual Studio（在 IIS express 中）在我的计算机上运行它时，它工作得很好。但是当我尝试在我的服务器（WS 2012，IIS 8）上托管网站时，页面需要永远加载。

我在日志中发现了这个错误：

C:\iis\beta\wwwroot>SET DNX_FOLDER=dnx-clr-win-x86.1.0.0-rc1-update1 

C:\iis\beta\wwwroot>SET "LOCAL_DNX=C:\iis\beta\approot\runtimes\dnx-clr-win-x86.1.0.0-rc1-update1\bin\dnx.exe" 

C:\iis\beta\wwwroot>IF EXIST C:\iis\beta\approot\runtimes\dnx-clr-win-x86.1.0.0-rc1-update1\bin\dnx.exe (SET "DNX_PATH=C:\iis\beta\approot\runtimes\dnx-clr-win-x86.1.0.0-rc1-update1\bin\dnx.exe" )

 goto :continue 
) ) 

C:\iis\beta\wwwroot>IF "" NEQ "" (SET "DNX_PATH=" ) 

C:\iis\beta\wwwroot>IF "C:\iis\beta\approot\runtimes\dnx-clr-win-x86.1.0.0-rc1-update1\bin\dnx.exe" == "" (SET "DNX_PATH=dnx.exe" )

Answer 1

我通过从 approot\src\website\ 中删除 global.json 解决了这个问题。

Answer 2

以F Andrei 的回答为基础。这个sn -p可以放在项目文件中，在每次文件系统发布后删除global.json。

<Target Name="AfterFileSystemPublish" AfterTargets="FileSystemPublish" Condition="'$(publishUrl)' != ''">
    <!-- 
          remove the src/*/global.json file as it prevents the web site from starting under IIS 
     -->
    <Message Text="Workaround:  Removing $(publishUrl)\approot\src\$(ProjectName)\global.json" Importance="high"/>
    <Exec WorkingDirectory="$(ProjectDir)" Command="del $(publishUrl)\approot\src\$(ProjectName)\global.json"/>
</Target>

Answer 3

请确保您在服务器上安装了 HttpPlatformHandler。您的应用程序池应配置为无托管代码

在配置方法的启动文件中，您能否确保您有以下行

application.UseIISPlatformHandler();

Answer 4

起初问题看起来并不那么明显。我遇到了同样的错误，经过一番努力想出了解决方案。

1. 像java仓库新的dnx项目结构保持user/xxx/.nuget/packages/ 所有的依赖项，所以如果那里有一个名字来带那个包，dnx会在那里寻找包
2. 这种情况下，其中一个包已损坏。所以解决方案是 如果您不完全知道发生异常的位置，请删除 .nuget 中的所有包。然后 dnu restore 将再次下载所有软件包。 然后问题就解决了。
