ASP.NET身份密码要求重写我自己的

所以我需要导入一堆用户到我的ASP。系统基于。NET身份，有些密码很短(只有三个字符)，超出了我的控制范围。我需要导入这些密码，以便现有用户可以登录和更改密码，以满足更严格的要求。

我认为通过在我的ApplicationUserManager类中配置PasswordValidator属性，我可以将导入密码的要求设置为一个较低的数字，从而允许我导入现有的用户。

// Configure validation logic for passwords
appUserManager.PasswordValidator = new PasswordValidator
{
    RequiredLength = 3,
    RequireNonLetterOrDigit = false,
    RequireDigit = false,
    RequireLowercase = false,
    RequireUppercase = false,
};

然而，当我导入用户并尝试创建新记录时，我在IdentityResult中得到验证错误。

IdentityResult result = manager.Create(newUser, importedUser.Password);

result.Errors = "Passwords must be at least 6 characters."

不可能覆盖标识默认需求吗?

这里是整个ApplicationUserManager类的参考:

public class ApplicationUserManager : UserManager<ApplicationUser>
{
    public ApplicationUserManager(IUserStore<ApplicationUser> store)
        : base(store)
    {
        PasswordValidator = new MinimumLengthValidator(3);
    }
    public static ApplicationUserManager Create(IdentityFactoryOptions<ApplicationUserManager> options, IOwinContext context)
    {
        var appDbContext = context.Get<ApplicationDbContext>();
        var appUserManager = new ApplicationUserManager(new UserStore<ApplicationUser>(appDbContext));
        // Configure validation logic for usernames
        appUserManager.UserValidator = new UserValidator<ApplicationUser>(appUserManager)
        {
            AllowOnlyAlphanumericUserNames = true,
            RequireUniqueEmail = false
        };
        // Configure validation logic for passwords
        appUserManager.PasswordValidator = new PasswordValidator
        {
            RequiredLength = 3,
            RequireNonLetterOrDigit = false,
            RequireDigit = false,
            RequireLowercase = false,
            RequireUppercase = false,
        };
        appUserManager.EmailService = new Services.EmailService();
        var dataProtectionProvider = options.DataProtectionProvider;
        if (dataProtectionProvider != null)
        {
            appUserManager.UserTokenProvider = new DataProtectorTokenProvider<ApplicationUser>(dataProtectionProvider.Create("ASP.NET Identity"))
            {
                //Code for email confirmation and reset password life time
                TokenLifespan = TimeSpan.FromHours(6)
            };
        }
        return appUserManager;
    }
}

foreach (var user in UserList)
{
    var manager = new UserManager<ApplicationUser>(new UserStore<ApplicationUser>(new ApplicationDbContext()));
    manager.PasswordValidator = new MinimumLengthValidator(3);
    var roleManager = new RoleManager<IdentityRole>(new RoleStore<IdentityRole>(new ApplicationDbContext()));
    var newUser = new ApplicationUser()
    {
        UserName = user.UserName,
        UserId = user.UserId,
        Email = user.Email,
        FirstName = user.FirstName,
        LastName = user.LastName,
    };

    // Assign the password
    IdentityResult result = manager.Create(newUser, user.Password);
    // Assign the role
    var addedUser = manager.FindByName(user.UserName);
    manager.AddToRoles(addedUser.Id, new string[] { "User" });
}
