Question

我正在摆弄身份，我肯定在挣扎 - 我已经搜索过，但没有任何表现。

我想在声明中添加声明，然后能够在我的页面上的视图中发布这些声明。

 public async Task<ClaimsIdentity> GenerateUserIdentityAsync(UserManager<ApplicationUser> manager)
    {
        var authenticationType = "Basic";
        var userIdentity = new ClaimsIdentity(await manager.GetClaimsAsync(this), authenticationType);

        // Add custom user claims here
        userIdentity.AddClaim(new Claim("FirstName", this.FirstName));

        return userIdentity;
    }
    public string FirstName { get; set; }
    public string LastName { get; set; }
    public string Address { get; set; }

在我的注册用户中，我将这些保存给用户：

public async Task<IActionResult> Register(RegisterViewModel model)
    {
        if (ModelState.IsValid)
        {
            var user = new ApplicationUser { UserName = model.Email, Email = model.Email, FirstName = model.FirstName, LastName = model.LastName};
            var result = await _userManager.CreateAsync(user, model.Password);
            if (result.Succeeded)
            {
                // For more information on how to enable account confirmation and password reset please visit http://go.microsoft.com/fwlink/?LinkID=532713
                // Send an email with this link
                //var code = await _userManager.GenerateEmailConfirmationTokenAsync(user);
                //var callbackUrl = Url.Action("ConfirmEmail", "Account", new { userId = user.Id, code = code }, protocol: HttpContext.Request.Scheme);
                //await _emailSender.SendEmailAsync(model.Email, "Confirm your account",
                //    "Please confirm your account by clicking this link: <a href=\"" + callbackUrl + "\">link</a>");
                await _signInManager.SignInAsync(user, isPersistent: false);
                _logger.LogInformation(3, "User created a new account with password.");
                return RedirectToAction(nameof(HomeController.Index), "Home");
            }
            AddErrors(result);
        }

        // If we got this far, something failed, redisplay form
        return View(model);
    }

注意，我检查了我的数据库，并存储了FirstName和LastName！

然后我扩展了我的身份（注意我删除了原始的返回，以检查它是否确实返回了null）

 public static class IdentityExtension
{
    public static string GetFirstName(this IIdentity identity)
    {
        var claim = ((ClaimsIdentity)identity).FindFirst("FirstName");
        // Test for null to avoid issues during local testing
        // return (claim != null) ? claim.Value : string.Empty;
        return claim.ToString() ;
    }


}

我现在认为我应该能够从我的剃刀视图访问数据，该视图位于 _Navigation.cshtml

@if (Context.User.Identity.IsAuthenticated)
            {
                <div class="dropdown profile-element">
                    <a data-toggle="dropdown" class="dropdown-toggle" href="#">
                        <span class="clear">
                            <span class="block m-t-xs">
                                <strong class="font-bold">Hello @User.Identity.GetFirstName()</strong>
                            </span>

我也尝试在没有扩展名的情况下直接执行此操作：

 @{
 if (Context.User.Identity.IsAuthenticated)
 {
     var FirstName = ((ClaimsIdentity)User.Identity).FindFirst("FirstName");
 } 
}

我显然错过了一些东西..我可以毫无问题地访问常规用户名。我已经搜索过，发现很多甚至可以到达这里，但很多都是不同的版本，所以我卡住了..

如果你能帮助我，我会很感激！

感谢。
