Question

我创建了一个基于Microsoft authorization example的项目，该项目生成了一个名为ApplicationUser的类。我正在尝试在创建帐户时向用户添加声明。

基于this SO post我会将声明添加到创建用户的构造函数中。但是，构造函数似乎没有显式存在于ApplicationUser类中（但登录工作正常）。如何向刚刚创建的用户添加声明？

此外，类ApplicationUser没有在Register方法中分配给它的属性UserName和Email，这让我觉得有很多事情要发生在背景我很想念。

ApplicationUser.cs

namespace xxx.Models
{
    public class ApplicationUser : IdentityUser
    {
    }
}

AccountController.cs

    private readonly UserManager<ApplicationUser> _userManager;
    public AccountController(
        UserManager<ApplicationUser> userManager,
        SignInManager<ApplicationUser> signInManager,
        IEmailSender emailSender,
        ILogger<AccountController> logger)
    {
        _userManager = userManager;
        _signInManager = signInManager;
        _emailSender = emailSender;
        _logger = logger;
    }

.........

    [HttpPost]
    [AllowAnonymous]
    [ValidateAntiForgeryToken]
    public async Task<IActionResult> Register(RegisterViewModel model, string returnUrl = null)
    {
        ViewData["ReturnUrl"] = returnUrl;
        if (ModelState.IsValid)
        {
            var user = new ApplicationUser { UserName = model.Email, Email = model.Email };
            var result = await _userManager.CreateAsync(user, model.Password);
            if (result.Succeeded)
            {
                _logger.LogInformation("User created a new account with password.");

                var code = await _userManager.GenerateEmailConfirmationTokenAsync(user);
                var callbackUrl = Url.EmailConfirmationLink(user.Id, code, Request.Scheme);
                await _emailSender.SendEmailConfirmationAsync(model.Email, callbackUrl);

                await _signInManager.SignInAsync(user, isPersistent: false);
                _logger.LogInformation("User created a new account with password.");
                return RedirectToLocal(returnUrl);
            }
            AddErrors(result);
        }

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

ApplicationUser没有在Register方法中分配给它的UserName和Email属性......

ApplicationUser继承了UserName类的Email和IdentityUser属性。这些属性和其他属性在其文档中列出here。

public class ApplicationUser : IdentityUser
{
}

如何向刚刚创建的用户添加声明？

向用户添加声明的一种方法是使用UserManager.AddClaimAsync方法。有一个example of doing that here。

在以下与您的Register方法类似的代码段中，我们在检查result.Succeeded之后将claim添加到新用户。

var user = new ApplicationUser { UserName = model.Email, Email = model.Email };
var result = await _userManager.CreateAsync(user, model.Password);
if (result.Succeeded)
{
    await _userManager.AddClaimAsync(user, new Claim("MyClaimType", "MyClaimValue"));
