【问题描述】：

我正在学习 ASP.NET 5 和 MVC6 的初学者教程，但在我的第一个项目中遇到了困难。我有一个应用程序应该只是将index.html 作为wwwroot 文件夹中的静态文件提供服务。但是，当我运行该项目时，出现 404 错误。

我的代码如下：

startup.cs

using System;
using System.Collections.Generic;
using System.Linq;
using System.Threading.Tasks;
using Microsoft.AspNetCore.Builder;
using Microsoft.AspNetCore.Hosting;
using Microsoft.AspNetCore.Http;
using Microsoft.Extensions.DependencyInjection;

namespace TheWorld
{
    public class Startup
    {
        // This method gets called by the runtime. Use this method to add services to the container.
        // For more information on how to configure your application, visit http://go.microsoft.com/fwlink/?LinkID=398940
        public void ConfigureServices(IServiceCollection services)
        {
        }

        // This method gets called by the runtime. Use this method to configure the HTTP request pipeline.
        public void Configure(IApplicationBuilder app)
        {
            app.UseStaticFiles();

            //app.Run(async (context) =>
            //{
            //    await context.Response.WriteAsync("Hello World!");
            //});
        }
    }
}

project.json

{
  "dependencies": {
    "Microsoft.NETCore.App": {
      "version": "1.0.0-rc2-3002702",
      "type": "platform"
    },
    "Microsoft.AspNetCore.Server.IISIntegration": "1.0.0-rc2-final",
    "Microsoft.AspNetCore.Server.Kestrel": "1.0.0-rc2-final",
    "Microsoft.AspNetCore.StaticFiles": "1.0.0-rc2-final"
  },

  "tools": {
    "Microsoft.AspNetCore.Server.IISIntegration.Tools": {
      "version": "1.0.0-preview1-final",
      "imports": "portable-net45+win8+dnxcore50"
    }
  },

  "frameworks": {
    "netcoreapp1.0": {
      "imports": [
        "dotnet5.6",
        "dnxcore50",
        "portable-net45+win8"
      ]
    }
  },

  "buildOptions": {
    "emitEntryPoint": true,
    "preserveCompilationContext": true
  },

  "runtimeOptions": {
    "gcServer": true
  },

  "publishOptions": {
    "include": [
      "wwwroot",
      "web.config"
    ]
  },

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

【解决方案1】：

添加 app.UseStaticFiles();在您的配置方法中

public void Configure(IApplicationBuilder app)
{
    app.UseStaticFiles();
}

将此依赖项添加到 project.Json 文件中

"Microsoft.AspNet.StaticFiles": "1.0.0-rc1-final"

我刚刚编辑了我的帖子，因为我忘了提及——当我添加那行代码时，我收到了这个错误：i.imgur.com/aJB5oPf.png
我添加了依赖项"Microsoft.AspNetCore.StaticFiles": "1.0.0-rc2-final"，它解决了我在编辑器中的错误，但是当我尝试从wwwroot 文件夹提供index.html 时，我的应用程序仍然是404。

【解决方案2】：

我已经找到了这个问题的答案。我需要将project.json 更改为如下所示：

  "dependencies": {
    "Microsoft.NETCore.App": {
      "version": "1.0.0-rc2-3002702",
      "type": "platform"
    },
    "Microsoft.AspNetCore.Server.IISIntegration": "1.0.0-rc2-final",
    "Microsoft.AspNetCore.Server.Kestrel": "1.0.0-rc2-final",
    "Microsoft.AspNetCore.StaticFiles": "1.0.0-rc2-final"
  },

并更改我的startup.cs 文件以包含以下行：

public void Configure(IApplicationBuilder app)
{
    app.UseFileServer();

    //app.Run(async (context) =>
    //{
    //    await context.Response.WriteAsync("Hello World!");
    //});
}
