在 IIS (10.0.17763.1) 上托管 .net5.0 核心 Web api 时出现问题

如何解决在 IIS (10.0.17763.1) 上托管 .net5.0 核心 Web api 时出现问题

我在 IIS 上托管我的 .net core 5.0 web api 时遇到问题，所以我决定创建一个基本的开箱即用版本 (WeatherForecast)。同样，这也不适用于 IIS（所以我不认为它不是我的代码）。我已经安装了 .Net Core Hosting Bundle 5.0 (V5.0.2) 并重新启动了 IIS（net stop was /y、net start w3svc）。

我的网站托管在 https://authdev.XXXXXXXX.net/api/weatherforecast（其中 XXXXXXXX.net 在我的内部网络上）。服务器是 Microsoft Hyper-V Server 2019。我有一个单独的应用程序池，.Net CLR 版本在集成管道模式下设置为“无托管代码”。我的网站设置了适当的绑定并正确配置。我已经通过创建一个从该服务器远程工作的 .Net Core 5.0 MVC 网站（开箱即用）确认了这一点。我在进程外模式下得到 404（并且相同的 url 在本地使用明显的服务器 url 更改）。我在某一阶段添加了日志信息，并注意到 Startup.cs 中的 public void Configure(IApplicationBuilder app,IWebHostEnvironment env) 方法没有被命中。

Error message 500.30 - ASP.NET Core app failed to start

我认为此消息表明我的托管环境配置正确，但我的（开箱即用）web api 中存在错误。

程序.cs

public class Program
{
    public static void Main(string[] args)
    {
        CreateHostBuilder(args).Build().Run();
    }

    public static IHostBuilder CreateHostBuilder(string[] args) =>
        Host.CreateDefaultBuilder(args)
            .ConfigureWebHostDefaults(webBuilder =>
            {
                webBuilder
                    .UseContentRoot(Directory.GetCurrentDirectory())
                    .UseKestrel()
                    .UseIISIntegration()
                    .UseStartup<Startup>();
            });
}

web.config

  <location path="." inheritInChildApplications="false">

</configuration>

Startup.cs

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.AddControllers();
        }

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

            app.UseHttpsRedirection();

            app.UseRouting();

            app.UseAuthorization();

            app.UseEndpoints(endpoints =>
            {
                endpoints.MapControllers();
            });
        }
    }

我尝试在进程内和进程外模式下运行它

解决方法

您确定要发布为自包含包吗？因为如果没有，您的配置应该如下所示：

      <aspNetCore processPath="dotnet"
                  arguments=".\WebApplication16.dll"
                  stdoutLogEnabled="false"
                  stdoutLogFile=".\logs\stdout"
                  hostingModel="inprocess" />
