Question

我正在使用此Dotnet核心MVC / Razor Pages应用程序，它应该防止用户通过搜索栏访问某些控制器路由，除非他们在注册表格中指定了它。我该如何实现？ dotnet核心MVC是否为此具有关键字？我被卡住了。下面显示了一些用于身份/帐户/注册的相关代码，显示正在注册

  [Required]
            [Display(Name = "Choose businesslisting or choice")]
            public string Decision { get; set; }
        }
   public void OnGet(string returnUrl = null)
        {
            ReturnUrl = returnUrl;
        }

        public async Task<IActionResult> OnPostAsync(string returnUrl = null)
        {
            returnUrl = returnUrl ?? Url.Content("~/");
            if (ModelState.IsValid)
            {
                var user = new IdentityUser { UserName = Input.Email, Email = Input.Email };
                var result = await _userManager.CreateAsync(user, Input.Password);

                if (Input.Decision == "Business Listing" || Input.Decision == "business listing")
                {

                    if (result.Succeeded)
                    {

                        _logger.LogInformation("User created a new account with password.");

                        var code = await _userManager.GenerateEmailConfirmationTokenAsync(user);
                        var callbackUrl = Url.Page(
                            "/Account/ConfirmEmail",
                            pageHandler: null, 
                            values: new { userId = user.Id, code = code },
                            protocol: Request.Scheme);

                        await _emailSender.SendEmailAsync(Input.Email, "Change your password",
                       $"Please change your password by <a href='{HtmlEncoder.Default.Encode(callbackUrl)}'>clicking here</a>.");

                        await _signInManager.SignInAsync(user, isPersistent: false);
                        return LocalRedirect(returnUrl);
                    }
}

我将从ASP.NET Core授权文档https://docs.microsoft.com/en-us/aspnet/core/security/authorization/introduction?view=aspnetcore-2.2

开始

在这种情况下，您可能会发现基于声明的身份验证很有用https://docs.microsoft.com/en-us/aspnet/core/security/authorization/claims?view=aspnetcore-2.2

创建用户后，您可以添加特定的声明，以允许他们访问特定的控制器/ URL。

如何防止用户通过搜索栏访问路线？
