在DotNet Core ASP中登录登录后调用函数

services.AddAuthentication(CookieAuthenticationDefaults.AuthenticationScheme)
    .AddCookie(options =>
    {
        options.LoginPath = "/Account/Login"; // 登录页面的路径
        options.AccessDeniedPath = "/Account/AccessDenied"; // 访问被拒绝页面的路径
    });

app.UseAuthentication();

public class AccountController : Controller
{
    [HttpGet]
    public IActionResult Login()
    {
        return View();
    }

    [HttpPost]
    public async Task<IActionResult> Login(LoginViewModel model)
    {
        if (ModelState.IsValid)
        {
            // 验证用户的用户名和密码，如果验证通过则使用Cookie身份验证来登录用户
            var claims = new List<Claim>
            {
                new Claim(ClaimTypes.Name, model.Username),
                // 添加其他用户信息的Claim
            };

            var claimsIdentity = new ClaimsIdentity(claims, CookieAuthenticationDefaults.AuthenticationScheme);
            var authProperties = new AuthenticationProperties
            {
                // 设置Cookie的过期时间等属性
            };

            await HttpContext.SignInAsync(CookieAuthenticationDefaults.AuthenticationScheme, new ClaimsPrincipal(claimsIdentity), authProperties);

            return RedirectToAction("Index", "Home"); // 登录成功后跳转到首页
        }

        return View(model);
    }

    [HttpPost]
    public async Task<IActionResult> Logout()
    {
        await HttpContext.SignOutAsync(CookieAuthenticationDefaults.AuthenticationScheme);

        return RedirectToAction("Index", "Home"); // 注销成功后跳转到首页
    }
}

public class LoginViewModel
{
    [Required]
    public string Username { get; set; }

    [Required]
    public string Password { get; set; }
}

public class HomeController : Controller
{
    public IActionResult Index()
    {
        // 在登录后调用的函数中进行相应的业务逻辑处理
        return View();
    }
}
