在 IIS 上托管 rc1-final-update1 时出现问题

Question

当我从 Visual studio（在 IIS express 中）在我的计算机上运行它时工作正常。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" )

这是我的 project.json:

Answer 1

您能否确保服务器上安装了 HttpPlatformHandler。您的应用程序池应配置为无托管代码

同样在配置方法中的启动文件中，请确保您有以下行

application.UseIISPlatformHandler();

Answer 2

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

Answer 3

基于的回答。可以将此代码段放在项目文件中，以便在每个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 4

起初问题看起来并不那么明显。我有同样的错误，经过一番努力想出了解决方案。

喜欢 java 存储库新的 dnx 项目结构保持 user/xxx/.nuget/packages/ 所有的依赖关系，所以如果那里存在一个名称来引入那个包，dnx 会在那里寻找包
这种情况下，其中一个软件包已损坏。所以解决方案是如果您不确切知道异常发生的原因，请删除 .nuget 中的所有包。然后 dnu restore 将再次下载所有包。那么问题就解决了。
