Question

我曾尝试为密码编写正则表达式：

public class ApplicationUser : IdentityUser, ITimeStamps
{
    public const string PasswordRegularExpression = @"admin|password";
    // public const string PasswordRegularExpression = @"/admin|password/i"; // Tried this too
    // public const string PasswordRegularExpression = @"/(admin|password)/i"; // Tried this too

这超出了正常的Microsoft身份标识：

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

这是我的注册视图模型：

public class RegisterViewModel
{
    [Required]
    [StringLength(100, ErrorMessage = "The {0} must be at least {2} characters long.", MinimumLength = 6)]
    [DataType(DataType.Password)]
    [Display(Name = "Password")]
    [RegularExpression( ApplicationUser.PasswordRegularExpression, ErrorMessage = "The {0} must contain atleast 1 number and must not contain the word 'admin' or 'password'" )] 
    public string Password { get; set; }

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

当有人在密码中使用密码或管理员时，我想在jquery验证中抛出错误。但是，jquery验证似乎没有按预期工作。我可能会缺少什么？

asp.net生成的html如下所示：

<input class="form-control input-validation-error" data-val="true" data-val-length="The Password must be at least 6 characters long." data-val-length-max="100" data-val-length-min="6" data-val-regex="The Password must contain atleast 1 number and must not contain the word 'admin' or 'password'" data-val-regex-pattern="admin|password" data-val-required="The Password field is required." id="Password" name="Password" placeholder="Enter a password" type="password">

测试用例：

我添加了括号，它仍然无法按预期工作。我输入密码，它实际上没有失败！然后我再添加1个字符（无论它是什么）然后它失败了...现在我删除了部分单词“password”，例如'pasrd21234'，错误仍然存在！

旁注：

我试过用它来测试它：http://regexhero.net/tester/并且正则表达式似乎在那里工作正常吗？
我也试过用它来测试它：http://regexpal.com/它运行正常吗？

根据Regular expression to match a line that doesn't contain a word?的答案，以下正则表达式应匹配任何密码，除非，如果它包含＆＃34; admin＆＃34;或＆＃34;密码＆＃34;：

^((?!(admin|password)).)*$

我已经在Regex101上创建了一个小提琴，以便在将其添加到您的应用程序之前进行测试。

匹配'密码'和'admin'的Jquery验证不起作用
