如何使用自签名客户端证书修复 asp.net core 3.1 中的 RevocationStatusUnknown

Question

我尝试实现一个 asp.net 核心 WebAPI 应用程序，使用客户端证书进行保护。我使用了来自 docs.microsoft 和其他站点的 Internet 示例代码。为了测试我构建的内容，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。
在运行应用程序之后，每次使用客户端证书调用该端点时，我都会收到 403 错误 Unathorized（从 Chrome 和 Firefox 尝试过）。除了 403，我还可以在控制台中看到一条消息“证书验证失败，主题是...”和“RevocationStatusUnknown The revocation function was unable to check revocation for the certificate ."
我不明白这个错误是从哪里来的，所以我无法追踪它。我尝试搜索 asp.net 核心源以获取部分短语或使用来自 Microsoft pdb 服务器的源代码符号进行调试，但我不明白错误的来源。我怀疑是因为我使用了自签名证书，但错误消息具有误导性。
这是我的代码： 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 class Program
    {
        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();
                        });
                    });
            });
    }
}

Startup.cs

using System;
using System.Security.Cryptography.X509Certificates;
using System.Text;
using System.Threading.Tasks;
using Microsoft.AspNetCore.Authentication.Certificate;
using Microsoft.AspNetCore.Builder;
using Microsoft.AspNetCore.Hosting;

using Microsoft.Extensions.DependencyInjection;
using Microsoft.Extensions.Hosting;

namespace AuthEndpoint
{
    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();
            services
                .AddAuthentication(CertificateAuthenticationDefaults.AuthenticationScheme)

                .AddCertificate(options =>
                {
                    options.AllowedCertificateTypes = CertificateTypes.All;
                    options.Events = new CertificateAuthenticationEvents
                    {
                        OnCertificateValidated = context =>

                            context.Success();
                            return Task.CompletedTask;
                        },
                        OnAuthenticationFailed = context =>
                        {
                            Console.WriteLine(context.Exception);
                            return Task.CompletedTask;

                        }
                    };
                })
                ;
            services.AddCertificateForwarding(options =>
                {
                    options.CertificateHeader = "X-ARR-ClientCert";
                    options.HeaderConverter = (headerValue) =>
                    {
                        X509Certificate2 clientCertificate = null;
                        if (!string.IsNullOrWhiteSpace(headerValue))
                        {
                            byte[] bytes = Encoding.UTF8.GetBytes(headerValue);
                            clientCertificate = new X509Certificate2(bytes);
                        }
                        return clientCertificate;
                    };
                });
            services.AddAuthorization();

        }

        // 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.UseCertificateForwarding();
            app.UseHttpsRedirection();

            app.UseRouting();

            app.UseAuthentication();
            app.UseAuthorization();

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

还有一个WeatherForecastController.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();
        }
    }
}

所以，我想知道如何让 asp.net 核心使用我的证书，或者如果没有办法使用自签名证书

Answer 1

在选项中的AddCertificate中需要设置下一行： options.RevocationMode = X509RevocationMode.NoCheck;
