1.我尝试实现一asp.net使用客户端证书保护的www.example.com核心WebAPI应用程序。我使用了来自docs.microsoft和其他站点的示例代码。为了测试我所构建的内容，我生成了CA证书、服务器证书和客户端证书。服务器和客户端证书都是使用该CA创建的。我还将CA证书添加到TrustedRoot存储中。
运行应用程序后，每次使用客户端证书调用该端点时，我都会收到403错误“未授权”（从Chrome和Firefox尝试）。沿着403，我还可以在控制台中看到消息“Certificate validation failed，subject was ...”和“RevocationStatusUnknown吊销函数无法检查证书的吊销。”
1.我不知道这个错误从何而来，所以我无法追踪它。我尝试搜寻asp.net核心来源，寻找部分词组或debug with using source code symbols from microsoft pdb servers，但我不知道这个错误从何而来。我怀疑是因为我使用自我签署凭证，但错误消息是误导性的。
1.下面是我的代码：Program.cs

using System.IO;
using System.Security.Cryptography.X509Certificates;
using Microsoft.AspNetCore.Hosting;
using Microsoft.AspNetCore.Server.Kestrel.Https;
using Microsoft.Extensions.Hosting;

namespace AuthEndpoint

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

        public static IHostBuilder CreateHostBuilder(string[] args) =>
            Host.CreateDefaultBuilder(args)
            .ConfigureWebHostDefaults(webBuilder =>
            {
                webBuilder
                    .UseStartup<Startup>()
                    .ConfigureKestrel(options =>
                    {
                        options.ConfigureHttpsDefaults(opt =>
                        {
                            opt.ServerCertificate = new X509Certificate2(Path.Combine("c:\\server\\server.pfx"),  "Password");
                            opt.ClientCertificateMode = ClientCertificateMode.RequireCertificate;
                            opt.CheckCertificateRevocation = false;
                            opt.AllowAnyClientCertificate();
                        });
                    });
            });
    }
}

和一个天气预报控制器. cs

using System;
using System.Collections.Generic;
using System.Linq;
using System.Threading.Tasks;
using Microsoft.AspNetCore.Authorization;
using Microsoft.AspNetCore.Mvc;
using Microsoft.Extensions.Logging;

namespace AuthEndpoint.Controllers
{
    [ApiController]
    [Route("[controller]")]
    [Authorize]
    public class WeatherForecastController : ControllerBase
    {
        private static readonly string[] Summaries = new[]
        {
            "Freezing", "Bracing", "Chilly", "Cool", "Mild", "Warm", "Balmy", "Hot", "Sweltering", "Scorching"
        };

        private readonly ILogger<WeatherForecastController> _logger;

        public WeatherForecastController(ILogger<WeatherForecastController> logger)
        {
            _logger = logger;
        }

        [HttpGet]
        public IEnumerable<WeatherForecast> Get()
        {
            var rng = new Random();
            return Enumerable.Range(1, 5).Select(index => new WeatherForecast
            {
                Date = DateTime.Now.AddDays(index),
                TemperatureC = rng.Next(-20, 55),
                Summary = Summaries[rng.Next(Summaries.Length)]
            })
            .ToArray();
        }
    }
}

因此，我想知道如何让asp.net核心使用我的证书，或者是否无法使用自签名证书
