Question

我创建了一个密码验证器，如下所示：

manager.PasswordValidator = new PasswordValidator
{
    RequiredLength = 8,
    RequireNonLetterOrDigit = false, 
    RequireDigit = false,
    RequireLowercase = true,
    RequireUppercase = true,
};

但是，测试123之类的密码被视为无效：

密码必须至少包含一个非字母或数字字符。

错误信息非常不清楚，它说密码应该至少有一个非字母或数字字符。好吧，我有3位数。那有什么不对呢？当我添加一个非字母

Answer 1

此属性的名称和documentation都不明确。这应该是：

获取或设置密码是否需要不是a的字符字母而不是数字。

Answer 2

    public class CustomPasswordValidator : PasswordValidator
{
    public override async Task<IdentityResult> ValidateAsync(string password)
    {
        var requireNonLetterOrDigit = base.RequireNonLetterOrDigit;
        base.RequireNonLetterOrDigit = false;
        var result = await base.ValidateAsync(password);

        if (!requireNonLetterOrDigit)
            return result;

        if (!Enumerable.All<char>((IEnumerable<char>)password, new Func<char, bool>(this.IsLetterOrDigit)))
            return result;

        // Build a new list of errors so that the custom 'PasswordRequireNonLetterOrDigit' could be added. 
        List<string> list = new List<string>();
        foreach (var error in result.Errors)
        {
            list.Add(error);
        }
        // Add our own message: (The default by MS is: 'Passwords must have at least one non letter or digit character.')
        list.Add("Passwords must have at least one character that is neither a letter or digit. (E.g. '£ $ % ^ _ etc.')");
        result = await Task.FromResult<IdentityResult>(IdentityResult.Failed(string.Join(" ", (IEnumerable<string>)list)));

        return result;
    }
}

RequireNonLetterOrDigit未正确验证
