C# ASP.NET Core 7 MVC Web 应用程序在某些 API 调用上带有客户端证书

问题描述 投票:0回答:1

我有一个 ASP.NET Core 7 MVC Web 应用程序,它具有完整的用户身份验证,但也有几个 API 端点。我们需要允许使用客户端证书而不是用户名/密码对这些端点进行身份验证。这可能吗?

我可以看到很多有关在 IIS 中打开客户端证书,甚至关闭某些端点的证书的文档,但我需要相反:我需要为某些端点打开它们,并保留所有其他端点。

过去我使用了可选证书,但浏览器仍然提示用户输入证书,我们不希望这样。

理想情况下,我想要一些简单的东西,只让我在调用特定端点时检查客户端证书,而不是在其他地方?

我问的是不可能的事吗?我是否需要创建一个新的 Web 应用程序并打开客户端证书来为这些端点提供服务?

您可以使用下面的代码通过客户端证书身份验证来保护您的特定 api 调用:

程序.cs:

using Microsoft.AspNetCore.Authentication.Certificate;
using System.Security.Cryptography.X509Certificates;

var builder = WebApplication.CreateBuilder(args);

// Add services to the container.
builder.Services.AddControllersWithViews();

builder.Services.AddAuthentication("Certificate")
    .AddCertificate(options =>
    {
        options.AllowedCertificateTypes = CertificateTypes.SelfSigned; // Adjust as necessary
        options.RevocationMode = X509RevocationMode.NoCheck;
        options.Events = new CertificateAuthenticationEvents
        {
            OnCertificateValidated = context =>
            {
                // Custom validation logic here, if needed
                context.Success();
                return Task.CompletedTask;
            }
        };
    });

builder.Services.AddAuthorization(options =>
{
    options.AddPolicy("ClientCertificatePolicy", policy =>
    {
        policy.AddAuthenticationSchemes("Certificate");
        policy.RequireAuthenticatedUser();
    });
});



var app = builder.Build();

// Configure the HTTP request pipeline.
if (!app.Environment.IsDevelopment())
{
    app.UseExceptionHandler("/Home/Error");
    // The default HSTS value is 30 days. You may want to change this for production scenarios, see https://aka.ms/aspnetcore-hsts.
    app.UseHsts();
}

app.UseHttpsRedirection();
app.UseStaticFiles();

app.UseRouting();

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



app.MapControllerRoute(
    name: "default",
    pattern: "{controller=Home}/{action=Index}/{id?}");

app.Run();

控制器:

using Microsoft.AspNetCore.Authorization;
using Microsoft.AspNetCore.Mvc;

namespace ClientCertApp.Controllers
{
    [ApiController]
    [Route("api/[controller]")]
    [Authorize(Policy = "ClientCertificatePolicy")]
    public class SecureApiController : ControllerBase
    {
        [HttpGet("data")]
        public IActionResult GetData()
        {
            return Ok(new { Message = "This endpoint is protected by client certificate authentication." });
        }
    }

}
