ASP.NET内置身份验证的控制器和视图可以在项目的Areas文件夹中的文件夹Identity中找到。以下是控制器和视图的示例：

控制器：

using Microsoft.AspNetCore.Identity;
using Microsoft.AspNetCore.Mvc;
using System.Threading.Tasks;

namespace MyApp.Areas.Identity.Controllers
{
    public class AccountController : Controller
    {
        private readonly SignInManager _signInManager;

        public AccountController(SignInManager signInManager)
        {
            _signInManager = signInManager;
        }

        [HttpGet]
        public IActionResult Login()
        {
            return View();
        }

        [HttpPost]
        public async Task Login(LoginViewModel model, string returnUrl)
        {
            if (ModelState.IsValid)
            {
                var result = await _signInManager.PasswordSignInAsync(model.UserName, model.Password, model.RememberMe, lockoutOnFailure: false);
                if (result.Succeeded)
                {
                    if (!string.IsNullOrEmpty(returnUrl) && Url.IsLocalUrl(returnUrl))
                    {
                        return Redirect(returnUrl);
                    }
                    else
                    {
                        return RedirectToAction(nameof(HomeController.Index), "Home");
                    }
                }
                else
                {
                    ModelState.AddModelError(string.Empty, "Invalid login attempt.");
                }
            }

            return View(model);
        }

        [HttpPost]
        public async Task Logout()
        {
            await _signInManager.SignOutAsync();
            return RedirectToAction(nameof(HomeController.Index), "Home");
        }
    }
}

视图：

@model MyApp.Areas.Identity.Pages.Account.LoginModel
@{
    ViewData["Title"] = "Log in";
}


    

    

        

            
@ViewData["Title"]
            

            

            

                
                
                <
