Aspnet核心Azure失败，HTTP错误502.5 - 进程失败

问题描述：

我想部署一个aspnet核心应用到Azure。这似乎通过OK去了，但是当我尝试启动，我看到下面的错误应用...Aspnet核心Azure失败，HTTP错误502.5 - 进程失败

这个问题的常见原因：

应用程序未能启动申请程序开始，但随后停止应用程序启动，但没有听配置的端口上

故障排除步骤：

检查系统事件日志中的错误消息启用日志记录的应用程序标准输出消息一个调试器附加到应用程序，并检查

似乎有很多写IIS在此，但不与Azure的，所以我在亏损在何处接下来看看。 Azure日志未指示任何内容。

微软的文档给我这个信息...

Platform conflicts with RID

Browser: HTTP Error 502.5 - Process Failure

Application Log: - Application Error: Faulting module: KERNELBASE.dll Exception code: 0xe0434352 Faulting module path: C:\WINDOWS\system32\KERNELBASE.dll - IIS AspNetCore Module: Failed to start process with commandline '"dotnet" .\my_application.dll' (portable app) or '"PATH\my_application.exe"' (self-contained app), ErrorCode = '0x80004005'.

ASP.NET Core Module Log: Unhandled Exception: System.BadImageFormatException: Could not load file or assembly 'teststandalone.dll' or one of its dependencies. An attempt was made to load a program with an incorrect format.

Troubleshooting:

If you published a self-contained application, confirm that you didn't set a platform in buildOptions of project.json that conflicts with the publishing RID. For example, do not specify a platform of x86 and publish with an RID of win81-x64 (dotnet publish -c Release -r win81-x64). The project will publish without warning or error but fail with the above logged exceptions on the server.

...但实际上并没有告诉我帮助这些设置应该是什么天青（或者如果它是相关的有），所以我”我不确定这是不是红鲱鱼。我没有在我的dotnet发布配置中指定-r开关。

我设法找到它一再抛出一些XML记录事件日志...

Failed to start process with commandline '"%LAUNCHER_PATH%" %LAUNCHER_ARGS%', ErrorCode = '0x80070002'.

经过调查，我发现我需要改变％LAUNCHER_PATH％和％LAUNCHER_ARGS％的值自己。我试过对web.config的各种更改，但没有运气。我的web.config现在看起来是这样......

<?xml version="1.0" encoding="utf-8"?> 
<configuration> 

    <!-- 
    Configure your application settings in appsettings.json. Learn more at http://go.microsoft.com/fwlink/?LinkId=786380 
    --> 

    <system.webServer> 
    <handlers> 
     <add name="aspNetCore" path="*" verb="*" modules="AspNetCoreModule" resourceType="Unspecified"/> 
    </handlers> 
    <aspNetCore processPath="dotnet" arguments="site\wwwroot\Esoterix.Modle.Portalweb.dll" stdoutLogEnabled="true" stdoutLogFile="LogFiles\stdout" forwardWindowsAuthToken="false"/> 
    </system.webServer> 
</configuration>

的路径是从Azure的部署的根，这似乎对于stdout日志文件路径的工作（我正与报告的错误），但不应用程序本身。我仍然看到下面的错误..

<Event> 
    <System> 
     <Provider Name="IIS AspNetCore Module"/> 
     <EventID>1000</EventID> 
     <Level>0</Level>

    </System> 
    <EventData> 
     <Data>Failed to start process with commandline '"dotnet" site\wwwroot\Esoterix.Modle.Portalweb.dll', ErrorCode = '0x80004005'.</Data> 
    </EventData> 
</Event>

这是重复4次

如果我看着我的标准输出输出我有以下...

Failed to load the dll from [\?\D:\home\site\wwwroot\hostpolicy.dll], HRESULT: 0x800700C1

An error occurred while loading required library hostpolicy.dll from [\?\D:\home\site\wwwroot]

如果我尝试直接与这里的web配置运行的exe ...

<?xml version="1.0" encoding="utf-8"?> 
<configuration> 

    <!-- 
    Configure your application settings in appsettings.json. Learn more at http://go.microsoft.com/fwlink/?LinkId=786380 
    --> 

    <system.webServer> 
    <handlers> 
     <add name="aspNetCore" path="*" verb="*" modules="AspNetCoreModule" resourceType="Unspecified"/> 
    </handlers> 
    <aspNetCore processPath="\\?\%home%\site\wwwroot\Esoterix.Modle.Portalweb.exe" arguments="" stdoutLogEnabled="true" stdoutLogFile="\\?\%home%\LogFiles\stdout" forwardWindowsAuthToken="false"/> 
    </system.webServer> 
</configuration>

然后我的标准输出给了我下面的错误...

Failed to load the dll from [\?\D:\home\site\wwwroot\hostfxr.dll], HRESULT: 0x80070057

The library hostfxr.dll was found, but loading it from \?\D:\home\site\wwwroot\hostfxr.dll failed

Installing .NET Core prerequisites might help resolve this problem.

答

我通过添加对dotnet-publish-iis的引用来解决此问题。

如何做到这一点的全部细节会被记录在GitHub的问题在https://github.com/aspnet/Hosting/issues/892
