c#之ASP.NET Core 2.2 Web API 在 IIS 上托管后给出 404

我创建了一个 ASP.Net Core 2.2 Web Api 项目，它在本地运行没有任何问题。在我将它发布到文件系统后，它总是给我 404 问题。我启用了与 IIS 和 asp.net 框架 web api2 应用程序相关的 Windows features 在同一台服务器上运行良好。

我启用了 swagger doc 并且也使用了 Microsoft.AspNetCore.Authentication 库。

Program.cs

using Microsoft.AspNetCore; 
using Microsoft.AspNetCore.Hosting; 
 
namespace US.BOX.AuthAPI 
{ 
    public class Program 
    { 
        public static void Main(string[] args) 
        { 
            CreateWebHostBuilder(args).Build().Run(); 
        } 
 
        public static IWebHostBuilder CreateWebHostBuilder(string[] args) => 
            WebHost.CreateDefaultBuilder(args) 
                .UseStartup<Startup>(); 
    } 
} 

Startup.cs

using Microsoft.AspNetCore.Authentication; 
using Microsoft.AspNetCore.Builder; 
using Microsoft.AspNetCore.Hosting; 
using Microsoft.AspNetCore.Http; 
using Microsoft.AspNetCore.Mvc; 
using Microsoft.Extensions.Configuration; 
using Microsoft.Extensions.DependencyInjection; 
using Microsoft.Extensions.Logging; 
using US.BOX.AuthAPI.Extensions; 
 
namespace US.BOX.AuthAPI 
{ 
    public class Startup 
    { 
        private readonly IConfiguration _configuration; 
        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.Configure<IISOptions>(options => 
            { 
                options.ForwardClientCertificate = false; 
            }); 
 
            services.Configure<ApiBehaviorOptions>(options => 
            { 
                options.SuppressModelStateInvalidFilter = true; 
            }); 
 
            services.AddSingleton<IHttpContextAccessor, HttpContextAccessor>(); 
            services.AddSingleton<IAuthenticationSchemeProvider, CustomAuthenticationSchemeProvider>(); 
 
            services.AddSwaggerDocumentation(); 
            services.AddJwtBearerAuthentication(_configuration); 
 
            services.AddCors(); 
            services.AddLogging(); 
 
            services.AddMvc() 
                .SetCompatibilityVersion(CompatibilityVersion.Version_2_2); 
 
        } 
 
        // This method gets called by the runtime. Use this method to configure the HTTP request pipeline. 
        public void Configure(IApplicationBuilder app, IHostingEnvironment env, ILoggerFactory loggerFactory, ILogger<Startup> logger) 
        { 
            app.UseAuthentication(); 
 
            if (env.IsDevelopment()) 
            { 
                app.UseSwaggerDocumentation(); 
            } 
            else 
            { 
                app.UseHsts(); 
            } 
 
            app.UseHttpsRedirection(); 
            app.UseMvc(); 
        } 
    } 
} 

appsettings.json

{ 
  "JWT": { 
    // TODO: This should be updated for production deployment 
    "SecurityKey": "sDIkdjhkalUthsaCVjsdfiskokrge", 
    "Issuer": "https://{host_name}:{port}", 
    "Audience": "https://{host_name}:{port}", 
    "ExpirationTimeInMinutes": 60 
  }, 
  "Logging": { 
    "LogFilePath": "Logs/auth-{Date}.txt", 
    "LogLevel": { 
      "Default": "Warning" 
    } 
  }, 
  "AllowedHosts": "*" 
} 

UsersController.cs

using System; 
using Microsoft.AspNetCore.Authorization; 
using Microsoft.AspNetCore.Mvc; 
 
namespace US.BOX.AuthAPI.Controllers 
{ 
    [Route("api/[controller]")] 
    [ApiController] 
    public class UsersController : ControllerBase 
    { 
        [HttpGet] 
        public IActionResult GetAll() 
        { 
            try 
            { 
                return Ok("Users"); 
            } 
            catch (Exception) 
            { 
 
                throw; 
            } 
        } 
    } 
} 

在我发布后它生成以下web.config 文件

<?xml version="1.0" encoding="utf-8"?> 
<configuration> 
  <location path="." inheritInChildApplications="false"> 
    <system.webServer> 
      <handlers> 
        <add name="aspNetCore" path="*" verb="*" modules="AspNetCoreModuleV2" resourceType="Unspecified" /> 
      </handlers> 
      <aspNetCore processPath="dotnet" arguments=".\US.BOX.AuthAPI.dll" stdoutLogEnabled="false" stdoutLogFile=".\logs\stdout" hostingModel="InProcess" /> 
    </system.webServer> 
  </location> 
</configuration> 

请您参考如下方法:

下面是一些 list ，您可以检查自己是否已经完成。

1. 为您的操作系统安装 dotnet 核心版本的 windows-hosting-bundle-installer。可以在下面下载link
2. 在您的 IIS 中为 dotnet 核心创建一个新的应用程序池，您可以查看下图的设置
3. 将与 dotnet 核心相关的任何应用程序定位到新创建的应用程序池，以进行所有托管。
