c# - ASP.NET Core Web API 跳过身份验证

Question

我正在根据以下示例使用自定义基本身份验证编写 ASP.NET Core Web 应用程序:
ASP.NET Core Web API Authentication
现在我在我的用户 Controller 中有一个操作来注册用户。因此，我想将此方法传递给我的自定义属性“SkipAuthAttribute”，以便说，如果有人调用此方法(操作)，您必须跳过身份验证(要注册的用户没有登录)。

但是 HttpContext 类型没有 ActionDescriptor 来获取 Action 的自定义属性

认识的人，我怎么能通过一些特定的 Action 跳过认证？

更新答案:
您应该尝试根据框架编写代码。示例中的中间件不适合 ASP.NET Core MVC。这是我的例子:

public class BasicAuthenticationHandler : AuthenticationHandler<BasicAuthenticationOptions>
    {
        protected override Task<AuthenticateResult> HandleAuthenticateAsync()
        {
            var authHeader = (string)this.Request.Headers["Authorization"];

            if (!string.IsNullOrEmpty(authHeader) && authHeader.StartsWith("basic", StringComparison.OrdinalIgnoreCase))
            {
                //Extract credentials
                string encodedUsernamePassword = authHeader.Substring("Basic ".Length).Trim();
                Encoding encoding = Encoding.GetEncoding("iso-8859-1");
                string usernamePassword = encoding.GetString(Convert.FromBase64String(encodedUsernamePassword));

                int seperatorIndex = usernamePassword.IndexOf(':');

                var username = usernamePassword.Substring(0, seperatorIndex);
                var password = usernamePassword.Substring(seperatorIndex + 1);

                if (username == "test" && password == "test")
                {
                    var user = new GenericPrincipal(new GenericIdentity("User"), null);
                    var ticket = new AuthenticationTicket(user, new AuthenticationProperties(), Options.AuthenticationScheme);
                    return Task.FromResult(AuthenticateResult.Success(ticket));
                }
            }

            return Task.FromResult(AuthenticateResult.Fail("No valid user."));
        }
    }

    public class BasicAuthenticationMiddleware : AuthenticationMiddleware<BasicAuthenticationOptions>
    {
        public BasicAuthenticationMiddleware(
           RequestDelegate next,
           IOptions<BasicAuthenticationOptions> options,
           ILoggerFactory loggerFactory,
           UrlEncoder encoder)
           : base(next, options, loggerFactory, encoder)
        {
        }

        protected override AuthenticationHandler<BasicAuthenticationOptions> CreateHandler()
        {
            return new BasicAuthenticationHandler();
        }
    }

    public class BasicAuthenticationOptions : AuthenticationOptions
    {
        public BasicAuthenticationOptions()
        {
            AuthenticationScheme = "Basic";
            AutomaticAuthenticate = true;
        }
    }

在 Startup.cs 注册 - app.UseMiddleware<BasicAuthenticationMiddleware>(); .使用此代码，您可以限制任何具有标准属性的 Controller Autorize :

[Authorize(ActiveAuthenticationSchemes = "Basic")]
[Route("api/[controller]")]
public class ValuesController : Controller

并使用属性 AllowAnonymous如果您在应用程序级别应用授权过滤器。

原答案:
From documentation

Add [AllowAnonymous] to the home controller so anonymous users can get information about the site before they register.

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

namespace ContactManager.Controllers {
[AllowAnonymous]
public class HomeController : Controller
{
    public IActionResult Index()
    {
        return View();
    }
