asp.net - AllowOnlyAlphanumericUserNames - 如何设置它？（RC 到 RTM 的重大变化）ASP.NET 标识

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 构造函数中：

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

Answer 2

还有另一种方法：

[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。
这是一些我使用自定义 UserManager 的代码来让事情正常工作
（这样在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 };
    }
}

这是 AccountController 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，现在将其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

另一种做事方式

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

您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);
