ASP.NET核心远程验证不工作

Question

我正在学习ASP.NET Core的教程，这是我第一次使用远程验证。 我已经仔细检查了我的代码，并在网上做了很多搜索，从我看到的所有例子和尝试中，我仍然得到同样的结果。 我一直收到验证方法的404 not found错误，我无法找出原因。这是我的代码。

在我的布局视图中，这里是我导入的文件。

这是我的ViewModel。

public class RegisterViewModel
    {
        [Remote("IsEmailInUse", "AccountController")]
        [Required]
        [EmailAddress]
        public string Email { get; set; }

        [Required]
        [StringLength(100, ErrorMessage = "The {0} must be at least {2} and at max {1} characters long.", MinimumLength = 6)]
        [DataType(DataType.Password)]
        [Display(Name = "Password")]
        public string Password { get; set; }

        [DataType(DataType.Password)]
        [Display(Name = "Confirm password")]
        [Compare("Password", ErrorMessage = "The password and confirmation password do not match.")]
        public string ConfirmPassword { get; set; }
    }

最后是控制器。

public class AccountController : Controller
    {
        private readonly UserManager<ApplicationUser> userManager;
        private readonly SignInManager<ApplicationUser> signInManager;

        public AccountController(UserManager<ApplicationUser> userManager, SignInManager<ApplicationUser> signInManager)
        {
            this.userManager = userManager;
            this.signInManager = signInManager;
        }

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

        [HttpPost]
        [AllowAnonymous]
        public async Task<IActionResult> Register(RegisterViewModel model)
        {
            if (ModelState.IsValid)
            {
                var user = new ApplicationUser
                {
                    UserName = model.Email,
                    Email = model.Email
                };

                var result = await userManager.CreateAsync(user, model.Password);

                if (result.Succeeded)
                {
                    await signInManager.SignInAsync(user, isPersistent: false);
                    return RedirectToAction("index", "home");
                }

                foreach (var error in result.Errors)
                {
                    ModelState.AddModelError("", error.Description);
                }
            }
            return View();
        }

        [HttpPost]
        public async Task<IActionResult> Logout()
        {
            await signInManager.SignOutAsync();
            return RedirectToAction("index", "home");
        }

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

        [HttpPost]
        [AllowAnonymous]
        public async Task<IActionResult> Login(LoginViewModel model, string returnUrl)
        {
            if (ModelState.IsValid)
            {
                var result = await signInManager.PasswordSignInAsync(model.Email, model.Password, model.RememberMe, false);

                if (result.Succeeded)
                {
                    if (!string.IsNullOrEmpty(returnUrl) && Url.IsLocalUrl(returnUrl))
                    {
                        return Redirect(returnUrl);
                    }
                    else
                    {
                        return RedirectToAction("index", "home");
                    }
                }
                ModelState.AddModelError(string.Empty, "Invalid Login Attempt");
            }
            return View();
        }

        [AcceptVerbs("GET", "POST")]
        [AllowAnonymous]
        public async Task<IActionResult> IsEmailInUse(string email)
        {
            var user = await userManager.FindByEmailAsync(email);

            if (user == null)
            {
                return Json(true);
            }
            else
            {
                return Json($"Email {email} is already in use.");
            }
        }

    }

Answer 1

控制器名称在 Remote 属性不正确，修改如下。

 [Remote("IsEmailInUse", "Account")]
