.NET Core - 仅在服务器上出现404错误

Question

我有一个非常简单的.NET Core测试应用程序，它在我的开发机器上运行，但在IIS 10下运行在我的服务器上时会产生404.最初，目标是在JSON中返回一些数据库记录，就像Web服务一样。但是，为了缩小搜索错误的范围，我已经更改了应用程序以返回单个常量字符串。结果是相同的 - 在开发机器上工作并在服务器上失败。

在开发机器上，我从Visual Studio 15.5.7运行它。我使用Web Deploy发布到服务器。

基于其他帖子，我也尝试为IIS应用程序池设置“无管理代码”，但它没有任何区别。

using System;
using System.Collections.Generic;
using System.Linq;
using System.Threading.Tasks;
using Microsoft.AspNetCore.Mvc;
using Newtonsoft.Json;
namespace api.iVoterGuide.com.Controllers
{
    [Route("api/ballot")]
    public class BallotController: Controller {
        // GET api/value  --  ballot/542
        [HttpGet("{eleck}")]
        public IEnumerable<string> Get(short elecK)
        {
            yield return "[ 1, 2, 3]";
        }
    }
}

这是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.Extensions.Configuration;
using Microsoft.Extensions.DependencyInjection;
using Microsoft.Extensions.Logging;
using Microsoft.Extensions.Options;

namespace api.iVoterGuide.com
{
    public class Startup
    {
        public Startup(IConfiguration configuration)
        {
            Configuration = configuration;
        }

        public IConfiguration Configuration { get; }

        // This method gets called by the runtime. Use this method to add services to the container.
        public void ConfigureServices(IServiceCollection services)
        {
            services.AddMvc();
        }

        // This method gets called by the runtime. Use this method to configure the HTTP request pipeline.
        public void Configure(IApplicationBuilder app, IHostingEnvironment env)
        {
            if (env.IsDevelopment())
            {
                app.UseDeveloperExceptionPage();
            }
            app.UseMvc();
        }
    }
}

Program.cs中

using System;
using System.Collections.Generic;
using System.IO;
using System.Linq;
using System.Threading.Tasks;
using Microsoft.AspNetCore;
using Microsoft.AspNetCore.Hosting;
using Microsoft.Extensions.Configuration;
using Microsoft.Extensions.Logging;

namespace api.iVoterGuide.com
{
    public class Program
    {
        public static void Main(string[] args)
        {
            BuildWebHost(args).Run();
        }

        public static IWebHost BuildWebHost(string[] args) =>
            WebHost.CreateDefaultBuilder(args)
                .UseStartup<Startup>()
                .Build();
    }
}

web.config中

<?xml version="1.0" encoding="utf-8"?>
<configuration>
     <!-- It works either with or without this CORS code -->
     <system.webServer>
          <handlers accessPolicy="Read, Execute, Script" />
          <httpProtocol>
               <customHeaders>
                    <add name="Access-Control-Allow-Origin" value="*" />
               </customHeaders>
          </httpProtocol>
      </system.webServer>
</configuration>

有没有人有什么建议？提前致谢。

编辑：按照另一篇文章（我再也找不到）的建议，我尝试从命令行运行我的应用程序。

D:\wwwroot\api.iVoterGuide.com>dotnet .\api.ivoterguide.com.dll
Error: An assembly specified in the application dependencies manifest (api.ivoterguide.com.deps.json) was not found:
package: 'Microsoft.ApplicationInsights.AspNetCore', version: '2.1.1'
path: 'lib/netstandard1.6/Microsoft.ApplicationInsights.AspNetCore.dll'
This assembly was expected to be in the local runtime store as the application was published using the following target manifest files:
aspnetcore-store-2.0.0-linux-x64.xml;aspnetcore-store-2.0.0-osx-x64.xml;aspnetcore-store-2.0.0-win7-x64.xml;aspnetcore-store-2.0.0-win7-x86.xml

这是服务器上的--info结果：

D:\wwwroot\api.iVoterGuide.com>dotnet --info
Microsoft .NET Core Shared Framework Host

Version  : 2.0.6
Build    : 74b1c703813c8910df5b96f304b0f2b78cdf194d

即使有了这些信息，我也无法解决问题。我已经尝试安装最新的.NET版本，在我的csproj（）中更改.NET Core版本，以及其他文章建议的其他一些小更改。

我仍然无法逃避。有什么建议。

Answer 1

您的web.config文件应包含以下内容：

<?xml version="1.0" encoding="utf-8"?>
<configuration>
<system.webServer>
<handlers>
<add name="aspNetCore" path="*" verb="*" modules="AspNetCoreModule"
resourceType="Unspecified" />
</handlers>
<aspNetCore processPath="dotnet" arguments=".\{dll's} path.dll" stdoutLogEnabled="false" stdoutLogFile=".\logs\stdout" />
</system.webServer>
</configuration>

Answer 2

解决方案是在服务器上安装.Net Core Windows Server Hosting，as described here。它可以是downloaded here。

没有必要在.csproj文件中将PublishWithAspNetCoreTargetManifest设置为false。

我可以从Visual Studio发布或使用命令行发布（dotnet发布-c Release -o bin \ PublishOutput）。后者要快得多。

Answer 3

检查IIS站点设置中的绑定。其中一个可能的原因是，如果在绑定中指定了IP地址，并且它被另一个应用程序使用
