如何在asp net core 3.1控制器中设置特定操作的基本身份验证？

[Authorize]
public IActionResult Action1()
{
    // 执行需要身份验证的操作
    return View();
}

services.AddAuthentication("BasicAuthentication")
    .AddScheme<AuthenticationSchemeOptions, BasicAuthenticationHandler>("BasicAuthentication", null);

public class BasicAuthenticationHandler : AuthenticationHandler<AuthenticationSchemeOptions>
{
    protected override async Task<AuthenticateResult> HandleAuthenticateAsync()
    {
        // 获取请求中的用户名和密码
        string authorizationHeader = Request.Headers["Authorization"];
        if (string.IsNullOrEmpty(authorizationHeader) || !authorizationHeader.StartsWith("Basic"))
        {
            // 未提供身份验证信息，或者不是基本身份验证
            return AuthenticateResult.Fail("Unauthorized");
        }

        // 解码用户名和密码
        string encodedCredentials = authorizationHeader.Substring("Basic ".Length).Trim();
        byte[] decodedBytes = Convert.FromBase64String(encodedCredentials);
        string decodedCredentials = Encoding.UTF8.GetString(decodedBytes);
        string[] parts = decodedCredentials.Split(':', 2);
        string username = parts[0];
        string password = parts[1];

        // 验证用户名和密码是否有效
        if (IsValidUser(username, password))
        {
            var claims = new[] { new Claim(ClaimTypes.Name, username) };
            var identity = new ClaimsIdentity(claims, Scheme.Name);
            var principal = new ClaimsPrincipal(identity);
            var ticket = new AuthenticationTicket(principal, Scheme.Name);

            return AuthenticateResult.Success(ticket);
        }
        else
        {
            return AuthenticateResult.Fail("Unauthorized");
        }
    }

    private bool IsValidUser(string username, string password)
    {
        // 在这里实现验证用户名和密码的逻辑
        // 可以从数据库、配置文件或其他存储中获取用户信息进行验证
        // 如果验证成功，返回true；否则，返回false
    }
}

app.UseAuthentication();
