Question

我在我的MVC项目中使用Identity，它一切都很好。除了注册新用户的表单有一些疯狂的密码要求之外

密码必须至少包含一个非字母或数字字符。密码必须至少有一位('0'-'9')。密码必须至少包含一个大写('A'-'Z')。

这是注册模型

public class RegisterViewModel
{
    [Required]
    [StringLength(50, ErrorMessage = "The {0} must be at least {2} characters long.", MinimumLength = 2)]
    [Display(Name = "First Name")]
    public string FirstName { get; set; }

    [Required]
    [StringLength(50, ErrorMessage = "The {0} must be at least {2} characters long.", MinimumLength = 2)]
    [Display(Name = "Last Name")]
    public string LastName { get; set; }

    [Required]
    [EmailAddress]
    [Display(Name = "Email")]
    public string Email { get; set; }

    [Required]
    [StringLength(100, ErrorMessage = "The {0} must be at least {2} characters long.", MinimumLength = 6)]
    [DataType(DataType.Password)]
    [Display(Name = "Passord")]
    public string Password { get; set; }

    [DataType(DataType.Password)]
    [Display(Name = "Repeat Password")]
    [Compare("Password", ErrorMessage = "The password and confirmation password do not match.")]
    public string ConfirmPassword { get; set; }
}

帐户控制器

    // POST: /Account/Register
    [HttpPost]
    [AllowAnonymous]
    [ValidateAntiForgeryToken]
    public async Task<ActionResult> Register(RegisterViewModel model)
    {
        if (ModelState.IsValid)
        {
            var user = new ApplicationUser { UserName = model.Email, Email = model.Email };
            var result = await UserManager.CreateAsync(user, model.Password);
            if (result.Succeeded)
            {
                await SignInManager.SignInAsync(user, isPersistent:false, rememberBrowser:false);
                return RedirectToAction("Index", "Home");
            }
            AddErrors(result);
        }

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

我看到了密码的长度要求，但我不明白如何更改密码验证，因此我不需要非字母或数字字符。

非常感谢所有人，谢谢。

奖励：{0}和{2}是什么意思？谢谢。

在添加身份服务的Startup.cs中，您可以添加密码验证选项：

services.AddIdentity<ApplicationUser, IdentityRole>(Configuration, 
    options => 
        options.Password = new PasswordOptions 
        { 
            RequireDigit = true, 
            RequiredLength = 6, 
            RequireLowercase = true, 
            RequireUppercase = true, 
            RequireNonLetterOrDigit = false 
        })
[...];

如果您使用其中一个ASP.NET模板应用程序并选择身份验证为“个人用户帐户”，您将在应用程序的App_Start文件夹中的IdentityConfig.cs文件中找到密码选项。您可以在此处更改密码选项，以关闭密码长度以外的所有要求：

manager.PasswordValidator = new PasswordValidator
        {
            RequiredLength = 6,
            RequireNonLetterOrDigit = false,
            RequireDigit = false,
            RequireLowercase = false,
            RequireUppercase = false,
        };

ASP.NET身份密码验证
