如何调试在Azure中部署的ASPNET Core MVC应用程序 [英] How do I debug an ASPNET Core MVC Application Deployed in Azure

问题描述

我已经创建了一个简单的ASPNET Core 1.0 MVC应用程序，我正在尝试使用Visual Studio将其部署到Azure.我可以使用IIS Express在本地计算机上运行此应用程序，并导航到默认路由并显示页面.但是，在Azure中，每次每次都会出现500错误，并且在这一点上，我对如何获取其他信息一无所知.

I've created a simple ASPNET Core 1.0 MVC app, which I am trying to deploy to Azure using Visual Studio. I am able to run this app locally on my machine using IIS Express, and navigate to my default route and display the page. However, in Azure I always get a 500 error every time, and at this point I am at a loss for how to get additional information.

我已经在我的Azure应用中启用了详细的请求日志记录，但是似乎并不能告诉我很多.

I've enabled detailed request logging in my Azure app, but it doesn't really seem to tell me much.

ModuleName="AspNetCoreModule", Notification="EXECUTE_REQUEST_HANDLER", HttpStatus="500", HttpReason="Internal Server Error", HttpSubStatus="0", ErrorCode="The operation completed successfully.
 (0x0)", ConfigExceptionInfo="" 

我已经将Startup配置简化为基本要求

I've stripped down my Startup configuration to the bare essentials

public void ConfigureServices(IServiceCollection services)
{
    services.AddMvc();
}

public void Configure(IApplicationBuilder app, ILoggerFactory loggingFactory)
{

    loggingFactory.AddConsole();
    loggingFactory.AddDebug();

    app.UseMvc(routes => {
        routes.MapRoute(
            name: "default",
            template: "{controller=Home}/{action=Index}/{id?}"
        );
    });

}

MVC管道中肯定有什么异常，但是我不知道如何增加可见性.我该怎么做才能获得更多信息?

Something must be blowing up in the MVC pipeline but I have no idea how to add more visibility. What can I do to get more information?

如果有关系的话，这就是我的Program.cs

And in case it matters, this is my Program.cs

var host = new WebHostBuilder()
    .UseKestrel()
    .UseContentRoot(Directory.GetCurrentDirectory())
    .UseIISIntegration()
    .UseStartup<Startup>()
    .Build();

host.Run();

推荐答案

尝试将ASPNETCORE_ENVIRONMENT设置为Development，以在错误页面上显示完整的异常消息.

Try setting ASPNETCORE_ENVIRONMENT to Development to display full exception message on the error page.

记住以在完成后将其关闭，否则您将泄漏错误信息.

Remember to turn it off when finished, otherwise you will leak error information.
