发布到Azure后,ASP.NET Core应用程序无法运行

Question

我有一个ASP.NET核心应用程序,在本地运行良好.

但是,当我将站点发布(Web部署)到Azure时,我得到403 : You do not have permission to view this directory or page.

我有一个默认控制器和Startup.cs中定义的路由:

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?)

想知道我应该在project.json或Kudu门户网站找到什么,以找出什么是错的？

我的project.json档案:

{
  "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,我错过了Microsoft.AspNetCore.Server.IISIntegrationNuGet包.当我添加它时,我还在web.config站点根目录中有一个文件(我通过它包含project.json).

我还添加.UseIISIntegration()到我WebHostBuilder的Startup.cs:

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

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

Azure中的事件日志指出: 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.

但是不确定这如何适用于Azure？

Answer 1

问题来自于 IIS 集成/配置不足。

我必须添加以下内容project.json：

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

我还添加了一个用于 IIS 发布的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中：

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

来自 Visual Studio 的标准发布（Web 部署）和网站在 Azure 上启动得很好（尽管在我的例子中，我还必须为某些 Gulp 任务添加预发布脚本）。
