AllowOnlyAlphanumericUsernames - 如何设置?(RC 到 RTM 重大变更)ASP.NET

Question

如何在Microsoft.AspNet.Identity.UserManager上设置AllowOnlyAlphanumericUserNames标志，以便UserValidator允许非字母数字用户名？

Answer 1

在 UserManager contructor：

UserValidator = new UserValidator<ApplicationUser>(this) { AllowOnlyAlphanumericUserNames = false };

Answer 2

另一种方法：

[Authorize]
public class AccountController : Controller
{
    public AccountController()
        : this(new UserManager<ApplicationUser>(new UserStore<ApplicationUser>(new ApplicationDbContext())))
    {
    }
    public AccountController(UserManager<ApplicationUser> userManager)
    {
        UserManager = userManager;
        // Start of new code
        UserManager.UserValidator = new UserValidator<ApplicationUser>(UserManager)
        {
            AllowOnlyAlphanumericUserNames = false,
        };
        // End of new code
    }
    public UserManager<ApplicationUser> UserManager { get; private set; }
}

Answer 3

约翰的回答是对的，我用他的回答允许电子邮件作为用户名（默认情况下不起作用）

请投票/接受约翰的回答。
这是我使用自定义用户管理器的一些代码"来使事情正常工作
（这样其他地方也减少了重复）

public class MyUserManager : UserManager<ApplicationUser>
{
    public MyUserManager(DbContext db)
        : base(new UserStore<ApplicationUser>(db))
    {
        this.UserValidator = UserValidator = new UserValidator<ApplicationUser>(this) 
          { AllowOnlyAlphanumericUserNames = false };
    }
}

下面是帐户控制器构造函数代码现在的样子：

[Authorize]
public class AccountController : Controller
{
    public AccountController()
        : this(new MyUserManager(new AppContext()))
    {
    }
    public AccountController(UserManager<ApplicationUser> userManager)
    {
        UserManager = userManager;
    }
    public UserManager<ApplicationUser> UserManager { get; private set; }

Answer 4

从 ASP.NET Identity 3.0（目前在RC中）开始，这现在配置为用户的一个选项。

public void ConfigureServices(IServiceCollection services)
{
    // (Rest of code removed)
    // Note the + added to the string of allowed user name characters
    services.AddIdentity<ApplicationUser, IdentityRole>(o => o.User.AllowedUserNameCharacters = @"abcdefghijklmnopqrstuvwxyzABCDEFGHIJKLMNOPQRSTUVWXYZ0123456789 -._@+")
    .AddEntityFrameworkStores<ApplicationDbContext>()
    .AddDefaultTokenProviders();

}

Answer 5

另一种方式

var manager = new ApplicationUserManager(new UserStore<ApplicationUser>(context.Get<ApplicationDbContext>()));
            // Configure validation logic for usernames
            manager.UserValidator = new UserValidator<ApplicationUser>(manager)
            {
                AllowOnlyAlphanumericUserNames = false,
                RequireUniqueEmail = true
            };
            // Configure validation logic for passwords
            manager.PasswordValidator = new PasswordValidator
            {
                RequiredLength = 6,
                RequireNonLetterOrDigit = true,
                RequireDigit = true,
                RequireLowercase = true,
                RequireUppercase = true,
            };

Answer 6

你可以像这样编写自己的UserValidator。然后使用它：

var userManager = new UserManager<ApplicationUser>(new CustomUserStore());
userManager.UserValidator = new CustomUserValidator<ApplicationUser>(userManager);
