.NET Core UserManager CreateAsync 使 UserName/Email/PhoneNumber 始终为空

Question

NET Core 应用程序为一些额外字段实现了自定义 IdentutyUser 逻辑。

我已经设法使用CreateAsync 创建了一个用户，但UserName、Email 和PhoneNumber 字段总是被忽略。它们的规范化版本（NormalizedUserName、NormalizedEmail 和 NormalizedPhoneNumber（最后一个是我创建的，因为任何不可为空的值都必须是唯一的））创建成功但总是大写。

控制器代码：

[HttpPost]
[AllowAnonymous]
[Route("Registration")]
public async Task<IActionResult> UserRegistration(ApplicationUserModel model)
{
    var applicationUser = new ApplicationUser()
    {
        UserName = model.UserName,
        Email = model.Email,
        PhoneNumber = model.PhoneNumber,
        FirstName = model.FirstName,
        // Other fields that are being inserted normally...
    };

    IdentityResult result = await _userManager.CreateAsync(applicationUser, model.Password);

    try
    {
        return Ok(result);
    }
    catch (Exception ex)
    {
        throw ex;
    }
}

如果它有助于有问题的字段被 ApplicationUser 模型类覆盖：

public class ApplicationUser : IdentityUser
{
    [Column("UserName", TypeName = "nvarchar(24)")]
    [Required(ErrorMessage = "UN_REQUIRED")]
    [StringLength(24, ErrorMessage = "UN_LENGTH", MinimumLength = 3)]
    [RegularExpression(@"[A-Za-z]+(?:[A-Za-z0-9-_])+(?:[_-]\w+)?$", ErrorMessage = "UN_INVALID")]
    public override string UserName { get; set; }

    [Column("Email", TypeName = "nvarchar(64)")]
    [Required(ErrorMessage = "EM_REQUIRED")]
    [StringLength(64, ErrorMessage = "EM_LENGTH", MinimumLength = 13)]
    [EmailAddress(ErrorMessage = "EM_INVALID")]
    public override string Email { get; set; }

    [Column("PhoneNumber", TypeName = "nvarchar(15)")]
    [Phone(ErrorMessage = "PN_INVALID")]
    public override string PhoneNumber { get; set; }

    ...
}

我在Startup.cs也有这个代码：

services.Configure<IdentityOptions>(options => {
    options.User.AllowedUserNameCharacters = "abcdefghijklmnopqrstuvwxyzABCDEFGHIJKLMNOPQRSTUVWXYZ0123456789-_";
    options.User.RequireUniqueEmail = true;
    options.Password.RequireDigit = true;
    options.Password.RequireLowercase = true;
    options.Password.RequireUppercase = true;
    options.Password.RequiredLength = 8;
    options.Password.RequireNonAlphanumeric = false;
});

如何将相应的值与其他值一起插入到数据库中？

Answer 1

添加自定义属性后，您应该在 ConfigureServices 中使用新的ApplicationUser：

services.AddDefaultIdentity<ApplicationUser>()
        .AddDefaultUI(UIFramework.Bootstrap4)
        .AddEntityFrameworkStores<ApplicationDbContext>();

还有ApplicationDbContext：

public class ApplicationDbContext : IdentityDbContext<ApplicationUser>

并确认您在控制器中使用新的 ApplicationUser 注入 UserManager：

private readonly UserManager<ApplicationUser> _userManager;

最后Add-migration xx，update-database 让 ef 在AspNetUsers 表中创建列。
