ASP.NET 发布到 Azure 后核心应用无法运行

Question

我有一个 ASP.NET 核心应用程序，它在本地运行运行良好。

但是，当我发布（Web 部署）站点到 Azure 时，我得到 403：You do not have permission to view this directory or page。

我在 Startup.cs:

中定义了默认控制器和路由

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

Web 部署到 Azure 后的文件夹结构如下所示：

|_ home
  |_ site
    |_ wwwroot (contains DLL's and files specified through 'publishOptions' in project.json)
      |_ wwwroot (the contents of the 'wwwroot' folder I have in Visual Studio)
      |_ Views (contains MVC views)
      |_ refs (contains referenced DLLs, I think?)

知道我应该在 project.json 或 Kudu 门户中查找什么以找出问题所在吗？

我的 project.json 文件：

{
  "title": "My Web App",
  "version": "1.0.0-*",
  "buildOptions": {
    "debugType": "portable",
    "emitEntryPoint": true,
    "preserveCompilationContext": true,
    "compile": {
      "exclude": [ "bin/**", "obj/**", "node_modules/" ]
    }
  },
  "publishOptions": {
    "include": [ "wwwroot", "Views", "appsettings.json", "appsettings.*.json" ]
  },
  "scripts": {
    "prepublish": [ "jspm install", "gulp build" ]
  },
  "dependencies": {
    "Microsoft.ApplicationInsights.AspNetCore": "1.0.0",
    "Microsoft.AspNetCore.Diagnostics": "1.0.0",
    "Microsoft.AspNetCore.Diagnostics.EntityFrameworkCore": "1.0.0",
    "Microsoft.AspNetCore.Mvc": "1.0.0",
    "Microsoft.AspNetCore.StaticFiles": "1.0.0",
    "Microsoft.Extensions.Configuration.Json": "1.0.0",
    "Microsoft.Extensions.Configuration.UserSecrets": "1.0.0",
    "Microsoft.Extensions.Logging.Console": "1.0.0",
    "Microsoft.Extensions.Logging.Debug": "1.0.0",
    "Microsoft.VisualStudio.Web.BrowserLink.Loader": "14.0.0",
    "System.IO.FileSystem": "4.0.1"
  },
  "frameworks": {
    "netcoreapp1.0": {
      "dependencies": {
        "Microsoft.NETCore.App": {
          "type": "platform",
          "version": "1.0.0"
        },
        "Microsoft.AspNetCore.Server.Kestrel": "1.0.0"
      },
      "imports": "dnxcore50"
    }
  },
  "commands": {
    "web": "Microsoft.AspNet.Server.Kestrel --server.urls=http://*:8000/"
  }
}

编辑：

首先，我缺少 Microsoft.AspNetCore.Server.IISIntegration NuGet 包。当我添加它时，我还在站点根目录中获得了一个 web.config 文件（我通过 project.json 包含了它）。

我还在Startup.cs中的WebHostBuilder中添加了.UseIISIntegration():

public static void Main(string[] args)
{
   new WebHostBuilder()
      .UseKestrel()
      .UseContentRoot(Directory.GetCurrentDirectory())
      .UseStartup<Startup>()
      .UseIISIntegration() // This was missing
      .Build()
      .Run();
   }

我现在可以在 IIS Express 本地运行它（虽然我猜它是 IIS fronting Kestrel？），但是当发布到 Azure 时我得到错误： HTTP Error 502.5 - Process Failure

Azure 中的事件日志状态：Failed to start process with commandline '"%LAUNCHER_PATH%" %LAUNCHER_ARGS%', ErrorCode = '0x80070002'.

根据文档，故障排除步骤是：

If the server does not have Internet access while installing the server hosting bundle, this exception will ensue when the installer is prevented from obtaining the Microsoft Visual C++ 2015 Redistributable (x64) packages online. You may obtain an installer for the packages from the Microsoft Download Center.

但不确定这如何适用于 Azure？

Answer 1

问题来自 IIS 不足 integration/configuration。

我必须将以下内容添加到 project.json：

"tools": {
    "Microsoft.AspNetCore.Server.IISIntegration.Tools": "1.0.0-preview2-final"
  }

我还为 IIS 发布添加了 postPublish 脚本：

"scripts": {
    "postpublish": [ "dotnet publish-iis --publish-folder %publish:OutputPath% --framework %publish:FullTargetFramework%" ]
  }

我还添加了 Microsoft.AspNetCore.Server.IISIntegration NuGet 包：

"dependencies": {
  "Microsoft.AspNetCore.Server.IISIntegration": "1.0.0"
}

这创建了一个 web.config 文件，我必须将其修改为：

<configuration>
  <system.webServer>
    <handlers>
      <add name="aspNetCore" path="*" verb="*" modules="AspNetCoreModule" resourceType="Unspecified" />
    </handlers>
    <aspNetCore processPath=".\My.Web.App.dll" arguments="" forwardWindowsAuthToken="false" stdoutLogEnabled="true" stdoutLogFile="\?\%home%\LogFiles\stdout" />
  </system.webServer>
</configuration>

最后我将 UseIISIntegration 添加到我的 WebHostBuilder:

public static void Main(string[] args)
{
   new WebHostBuilder()
      .UseKestrel()
      .UseContentRoot(Directory.GetCurrentDirectory())
      .UseStartup<Startup>()
      .UseIISIntegration() // This was missing
      .Build()
      .Run();
   }

来自 Visual Studio 的标准 Publish（Web 部署）并且该网站在 Azure 上启动得很好（尽管在我的情况下我还必须添加一个 prepublish 一些 Gulp 任务的脚本。
