如何本地化ASP.NET身份用户名和密码错误消息？

是否有可能为“系统”ASP.NET Identity v1错误消息提供本地化的string，如“ 名称XYZ已被占用 ”或“ 用户名称XYZ无效，只能包含字母或数字 ”？

Answer 1

还没有，我们有一个跟踪这个工作项目的错误，以便指定资源的来源。

Answer 2

截至2014年3月20日发布的第2版身份，您现在可以拥有本地化的错误消息。

首先安装身份本地化软件包。

Install-Package Microsoft.AspNet.Identity.Core.fr 

然后，必须设置适当的文化，以获得本地化的消息，例如设置文化的一种方式是在web.config中

 <system.web> <globalization culture="fr-FR" uiCulture="fr"/> </system.web> 

Answer 3

对于ASP.NET Core：（Microsoft.AspNetCore.Identity 1.0.0）

创build一个inheritanceIdentityErrorDescriber的类并覆盖所需的错误消息。

 public class CustomIdentityErrorDescriber : IdentityErrorDescriber { public override IdentityError DefaultError() { return new IdentityError { Code = nameof(DefaultError), Description = $"An unknown failure has occurred." }; } public override IdentityError ConcurrencyFailure() { return new IdentityError { Code = nameof(ConcurrencyFailure), Description = "Optimistic concurrency failure, object has been modified." }; } public override IdentityError PasswordMismatch() { return new IdentityError { Code = nameof(PasswordMismatch), Description = "Incorrect password." }; } public override IdentityError InvalidToken() { return new IdentityError { Code = nameof(InvalidToken), Description = "Invalid token." }; } public override IdentityError LoginAlreadyAssociated() { return new IdentityError { Code = nameof(LoginAlreadyAssociated), Description = "A user with this login already exists." }; } public override IdentityError InvalidUserName(string userName) { return new IdentityError { Code = nameof(InvalidUserName), Description = $"User name '{userName}' is invalid, can only contain letters or digits." }; } public override IdentityError InvalidEmail(string email) { return new IdentityError { Code = nameof(InvalidEmail), Description = $"Email '{email}' is invalid." }; } public override IdentityError DuplicateUserName(string userName) { return new IdentityError { Code = nameof(DuplicateUserName), Description = $"User Name '{userName}' is already taken." }; } public override IdentityError DuplicateEmail(string email) { return new IdentityError { Code = nameof(DuplicateEmail), Description = $"Email '{email}' is already taken." }; } public override IdentityError InvalidRoleName(string role) { return new IdentityError { Code = nameof(InvalidRoleName), Description = $"Role name '{role}' is invalid." }; } public override IdentityError DuplicateRoleName(string role) { return new IdentityError { Code = nameof(DuplicateRoleName), Description = $"Role name '{role}' is already taken." }; } public override IdentityError UserAlreadyHasPassword() { return new IdentityError { Code = nameof(UserAlreadyHasPassword), Description = "User already has a password set." }; } public override IdentityError UserLockoutNotEnabled() { return new IdentityError { Code = nameof(UserLockoutNotEnabled), Description = "Lockout is not enabled for this user." }; } public override IdentityError UserAlreadyInRole(string role) { return new IdentityError { Code = nameof(UserAlreadyInRole), Description = $"User already in role '{role}'." }; } public override IdentityError UserNotInRole(string role) { return new IdentityError { Code = nameof(UserNotInRole), Description = $"User is not in role '{role}'." }; } public override IdentityError PasswordTooShort(int length) { return new IdentityError { Code = nameof(PasswordTooShort), Description = $"Passwords must be at least {length} characters." }; } public override IdentityError PasswordRequiresNonAlphanumeric() { return new IdentityError { Code = nameof(PasswordRequiresNonAlphanumeric), Description = "Passwords must have at least one non alphanumeric character." }; } public override IdentityError PasswordRequiresDigit() { return new IdentityError { Code = nameof(PasswordRequiresDigit), Description = "Passwords must have at least one digit ('0'-'9')." }; } public override IdentityError PasswordRequiresLower() { return new IdentityError { Code = nameof(PasswordRequiresLower), Description = "Passwords must have at least one lowercase ('a'-'z')." }; } public override IdentityError PasswordRequiresUpper() { return new IdentityError { Code = nameof(PasswordRequiresUpper), Description = "Passwords must have at least one uppercase ('A'-'Z')." }; } } 

在您的Startup类上，在ConfigureServices中注册自定义ErrorDesigned：

 services.AddIdentity<ApplicationUser, IdentityRole>() .AddErrorDescriber<CustomIdentityErrorDescriber>(); // Add this line 

更新：下面你可以find西class牙语和葡萄牙语已经翻译的版本。 仔细检查他们！

 public class SpanishIdentityErrorDescriber : IdentityErrorDescriber { public override IdentityError DefaultError() { return new IdentityError { Code = nameof(DefaultError), Description = $"Ha ocurrido un error." }; } public override IdentityError ConcurrencyFailure() { return new IdentityError { Code = nameof(ConcurrencyFailure), Description = "Ha ocurrido un error, el objeto ya ha sido modificado (Optimistic concurrency failure)." }; } public override IdentityError PasswordMismatch() { return new IdentityError { Code = nameof(PasswordMismatch), Description = "Password Incorrecta." }; } public override IdentityError InvalidToken() { return new IdentityError { Code = nameof(InvalidToken), Description = "Ha ingresado un código Inválido." }; } public override IdentityError LoginAlreadyAssociated() { return new IdentityError { Code = nameof(LoginAlreadyAssociated), Description = "Un usuario con ese nombre ya existe." }; } public override IdentityError InvalidUserName(string userName) { return new IdentityError { Code = nameof(InvalidUserName), Description = $"El nombre de usuario '{userName}' es inválido.

Puede recupar su contraseña para ingresar nuevamente al sistema." }; } public override IdentityError InvalidRoleName(string role) { return new IdentityError { Code = nameof(InvalidRoleName), Description = $"El nombre de rol '{role}' es inválido." }; } public override IdentityError DuplicateRoleName(string role) { return new IdentityError { Code = nameof(DuplicateRoleName), Description = $"El nombre de rol '{role}' ya existe." }; } public override IdentityError UserAlreadyHasPassword() { return new IdentityError { Code = nameof(UserAlreadyHasPassword), Description = "El usuario ya tiene contraseña." }; } public override IdentityError UserLockoutNotEnabled() { return new IdentityError { Code = nameof(UserLockoutNotEnabled), Description = "El bloqueo no esta habilitado para este usuario." }; } public override IdentityError UserAlreadyInRole(string role) { return new IdentityError { Code = nameof(UserAlreadyInRole), Description = $"El usuario ya es parte del rol '{role}'." }; } public override IdentityError UserNotInRole(string role) { return new IdentityError { Code = nameof(UserNotInRole), Description = $"El usuario no es parte del rol '{role}'." }; } public override IdentityError PasswordTooShort(int length) { return new IdentityError { Code = nameof(PasswordTooShort), Description = $"La contraseña deben tener un largo mínimo de {length} caracteres." }; } public override IdentityError PasswordRequiresNonAlphanumeric() { return new IdentityError { Code = nameof(PasswordRequiresNonAlphanumeric), Description = "La contraseña debe contener al menos un caracter alfanumérico." }; } public override IdentityError PasswordRequiresDigit() { return new IdentityError { Code = nameof(PasswordRequiresDigit), Description = "La contraseña debe incluir al menos un dígito ('0'-'9')." }; } public override IdentityError PasswordRequiresLower() { return new IdentityError { Code = nameof(PasswordRequiresLower), Description = "La contraseña debe incluir al menos una letra minúscula ('a'-'z')." }; } public override IdentityError PasswordRequiresUpper() { return new IdentityError { Code = nameof(PasswordRequiresUpper), Description = "La contraseña debe incluir al menos una letra MAYÚSCULA ('A'-'Z')." }; } }

 public class PortugueseIdentityErrorDescriber : IdentityErrorDescriber { public override IdentityError DefaultError() { return new IdentityError { Code = nameof(DefaultError), Description = $"Um erro desconhecido ocorreu." }; } public override IdentityError ConcurrencyFailure() { return new IdentityError { Code = nameof(ConcurrencyFailure), Description = "Falha de concorrência otimista, o objeto foi modificado." }; } public override IdentityError PasswordMismatch() { return new IdentityError { Code = nameof(PasswordMismatch), Description = "Senha incorreta." }; } public override IdentityError InvalidToken() { return new IdentityError { Code = nameof(InvalidToken), Description = "Token inválido." }; } public override IdentityError LoginAlreadyAssociated() { return new IdentityError { Code = nameof(LoginAlreadyAssociated), Description = "Já existe um usuário com este login." }; } public override IdentityError InvalidUserName(string userName) { return new IdentityError { Code = nameof(InvalidUserName), Description = $"Login '{userName}' é inválido, pode conter apenas letras ou dígitos." }; } public override IdentityError InvalidEmail(string email) { return new IdentityError { Code = nameof(InvalidEmail), Description = $"Email '{email}' é inválido." }; } public override IdentityError DuplicateUserName(string userName) { return new IdentityError { Code = nameof(DuplicateUserName), Description = $"Login '{userName}' já está sendo utilizado." }; } public override IdentityError DuplicateEmail(string email) { return new IdentityError { Code = nameof(DuplicateEmail), Description = $"Email '{email}' já está sendo utilizado." }; } public override IdentityError InvalidRoleName(string role) { return new IdentityError { Code = nameof(InvalidRoleName), Description = $"A permissão '{role}' é inválida." }; } public override IdentityError DuplicateRoleName(string role) { return new IdentityError { Code = nameof(DuplicateRoleName), Description = $"A permissão '{role}' já está sendo utilizada." }; } public override IdentityError UserAlreadyHasPassword() { return new IdentityError { Code = nameof(UserAlreadyHasPassword), Description = "Usuário já possui uma senha definida." }; } public override IdentityError UserLockoutNotEnabled() { return new IdentityError { Code = nameof(UserLockoutNotEnabled), Description = "Lockout não está habilitado para este usuário." }; } public override IdentityError UserAlreadyInRole(string role) { return new IdentityError { Code = nameof(UserAlreadyInRole), Description = $"Usuário já possui a permissão '{role}'." }; } public override IdentityError UserNotInRole(string role) { return new IdentityError { Code = nameof(UserNotInRole), Description = $"Usuário não tem a permissão '{role}'." }; } public override IdentityError PasswordTooShort(int length) { return new IdentityError { Code = nameof(PasswordTooShort), Description = $"Senhas devem conter ao menos {length} caracteres." }; } public override IdentityError PasswordRequiresNonAlphanumeric() { return new IdentityError { Code = nameof(PasswordRequiresNonAlphanumeric), Description = "Senhas devem conter ao menos um caracter não alfanumérico." }; } public override IdentityError PasswordRequiresDigit() { return new IdentityError { Code = nameof(PasswordRequiresDigit), Description = "Senhas devem conter ao menos um digito ('0'-'9')." }; } public override IdentityError PasswordRequiresLower() { return new IdentityError { Code = nameof(PasswordRequiresLower), Description = "Senhas devem conter ao menos um caracter em caixa baixa ('a'-'z')." }; } public override IdentityError PasswordRequiresUpper() { return new IdentityError { Code = nameof(PasswordRequiresUpper), Description = "Senhas devem conter ao menos um caracter em caixa alta ('A'-'Z')." }; } } 

Answer 4

我遇到了同样的问题，发现一个快速和肮脏的解决方法。 我查看了使用DotPeek的Microsoft.AspNet.Identity.Core程序集（我假设任何C＃反编译程序都会这样做），并且发现了两个负责这样的消息的类：

• Microsoft.AspNet.Identity.UserValidator<TUser> （与用户名有关）
• Microsoft.AspNet.Identity.MinimumLengthValidator （与密码相关）

这些类不包含任何外部引用（除了要replace的string资源之外），因此在自己的代码中重新实现它们应该相当简单。

这样做后，不要忘记在你的UserManager正确使用它们：

 UserManager.UserValidator = new MyCustomUserValidator<MyUserType>(UserManager); UserManager.PasswordValidator = new MyCustomMinimumLengthValidator(6); 

Answer 5

ASP NET Core解决方法（25.11.2016）

您可以将IStringLocalizer注入到自定义IdentityErrorDescriber中

1）创build自定义IdentityErrorDescriber（请参阅Gerardo Grignoli的答案）

 public class MultilanguageIdentityErrorDescriber : IdentityErrorDescriber { private readonly IStringLocalizer<SharedResource> _localizer; public MultilanguageIdentityErrorDescriber(IStringLocalizer<SharedResource> localizer) { _localizer = localizer; } public override IdentityError DuplicateEmail(string email) { return new IdentityError() { Code = nameof(DuplicateEmail), Description = string.Format(_localizer["Email {0} is already taken."], email) }; } // DuplicateUserName, InvalidEmail, DuplicateUserName etc } 

2）在Startup.cs中注册MultilanguageIdentityErrorDescriber

 services.AddIdentity<IdentityUser, IdentityRole>() .AddErrorDescriber<MultilanguageIdentityErrorDescriber>() .AddDefaultTokenProviders(); 

3）将错误消息添加到SharedResource.language.resx。

Answer 6

1AmirJalali的方法完美。 虽然在web.config中设置文化的工作，如果需要也可以dynamic设置，这是如何实现的：

 Thread.CurrentThread.CurrentCulture = new System.Globalization.CultureInfo(cultureName); Thread.CurrentThread.CurrentUICulture = Thread.CurrentThread.CurrentCulture; 

在上面的代码示例中，cultureName是要设置的文化的名称。 可以在“备注”标题下find文化列表： http : //msdn.microsoft.com/en-us/library/system.globalization.cultureinfo%28v=vs.80%29.aspx

希望这可以帮助。

Answer 7

这个问题已经困扰了我很长一段时间了，所以我试图想出一些通用的，因为解决scheme与特定的文化安装Identity.Core只工作，如果包是可用的所有:)

以下是我如何实现适当的本地化的步骤：

1. 看着在ApplicationUserManager默认使用的使用dotPeak的Microsoft.AspNet.Identity.PasswordValidator的实现，
2. 然后，我想出了我自己实现的class CustomPasswordValidator : PasswordValidator并覆盖ValidateAsync方法不返回带有错误消息的IdentityResult ，而是与这些错误消息的“代码”，所有这些错误消息前缀“CustomValidator”string。
3. 然后在AccountController我更改了从Register邮件中调用的AddErrors ，以便根据错误代码从我自己的资源文件中提供本地化的错误消息。

这里是CustomPasswordValidator和实用程序类PasswordValidatorCodes包含错误代码和方法来检索基于这些代码本地化的错误消息（AccountStrings是一个资源文件）：

 public static class PasswordValidatorCodes { public const string ErrorCodePrefix = "CustomPassword"; public const string PasswordTooShort = ErrorCodePrefix + "TooShort"; public const string PasswordRequireNonLetterOrDigit = ErrorCodePrefix + "RequireNonLetterOrDigit"; public const string PasswordRequireDigit = ErrorCodePrefix + "RequireDigit"; public const string PasswordRequireLower = ErrorCodePrefix + "RequireLower"; public const string PasswordRequireUpper = ErrorCodePrefix + "RequireUpper"; public static string GetLocalizedMessageForCode(string code) { switch (code) { case PasswordTooShort: return string.Format(AccountStrings.ValidationPasswordTooShort, CustomPasswordValidator.RequiredPasswordLength); case PasswordRequireNonLetterOrDigit: return AccountStrings.ValidationPasswordRequireNonLetterOrDigit; case PasswordRequireDigit: return AccountStrings.ValidationPasswordRequireDigit; case PasswordRequireLower: return AccountStrings.ValidationPasswordRequireLower; case PasswordRequireUpper: return AccountStrings.ValidationPasswordRequireUpper; default: throw new ArgumentException("code"); } } } public class CustomPasswordValidator : PasswordValidator { public const int RequiredPasswordLength = 6; public CustomPasswordValidator() { RequiredLength = RequiredPasswordLength; RequireNonLetterOrDigit = false; RequireDigit = true; RequireLowercase = true; RequireUppercase = false; } public override Task<IdentityResult> ValidateAsync(string item) { if (item == null) throw new ArgumentNullException("item"); var list = new List<string>(); if (string.IsNullOrWhiteSpace(item) || item.Length < RequiredLength) { list.Add(PasswordValidatorCodes.PasswordTooShort); } if (RequireNonLetterOrDigit && item.All(IsLetterOrDigit)) { list.Add(PasswordValidatorCodes.PasswordRequireNonLetterOrDigit); } if (RequireDigit && item.All(c => !IsDigit(c))) { list.Add(PasswordValidatorCodes.PasswordRequireDigit); } if (RequireLowercase && item.All(c => !IsLower(c))) { list.Add(PasswordValidatorCodes.PasswordRequireLower); } if (RequireUppercase && item.All(c => !IsUpper(c))) { list.Add(PasswordValidatorCodes.PasswordRequireUpper); } return Task.FromResult(list.Count == 0 ? IdentityResult.Success : new IdentityResult(list)); } } 

这里是修改后的AccountController.AddErrors方法。 正如你可以看到我添加一个错误的属性Password的模型，因为如果Password没有通过validation，那么我想错误消息显示的Password字段，而不是在validation总结。 这是我的CustomPasswordValidator直接生成错误代码而不是错误消息的唯一原因：

 private void AddErrors(IdentityResult result) { foreach (var error in result.Errors) { if (error.StartsWith(PasswordValidatorCodes.ErrorCodePrefix)) { ModelState.AddModelError("Password", PasswordValidatorCodes.GetLocalizedMessageForCode(error)); continue; } ModelState.AddModelError(string.Empty, error); } } 

最后但并非最不重要的，不要忘记修改IdentityConfig文件，即：

 manager.PasswordValidator = new CustomPasswordValidator(); 

更新：

直到现在，我注意到Marselus Chia（见其他答案）已经提出了类似的解决scheme，但为VB。

Answer 8

让我和你分享我用西class牙语来完成这件事情。 在那里你可以轻松地自定义消息！

string Errores = result.Errors.FirstOrDefault(); Errores = Errores.Replace("Name " + Email.Text + " is already taken.", "- El mail " + Email.Text + " ya fue registrado. Intente recuperar la clave.<br/>"); Errores = Errores.Replace("Passwords must be at least 6 characters.", "- La clave debe contener por lo menos 6 caracteres.<br/>"); Errores = Errores.Replace("Passwords must have at least one non letter or digit character.", "- La clave debe contener por lo menos un caracter que no sea letra ni dígito. Por ejemplo: un punto.<br/>"); Errores = Errores.Replace("Passwords must have at least one digit ('0'-'9').", "- La clave debe contener al menos un dígito (entre 0 y 9).<br/>"); Errores = Errores.Replace("Passwords must have at least one uppercase ('A'-'Z').", "- La clave debe contener al menos una letra (entre A y Z).<br/>"); ErrorMessage.Text = "Errores:<br/><br/>" + Errores;

Answer 9

我的解决scheme是从Microsoft.AspNet.Identity.PasswordValidator创build新的自定义密码validation类inheritance，覆盖发出错误消息的ValidateAsync。 自定义错误信息在这里，它适用于我…

这些类假设你有一个全局资源文件名validation器。 这些类和资源文件示例中的脚本可以在这里findASP.NET身份 – Codeplex示例代码

这是我在vb.net中的示例工作代码

请记住更新您的identityConfig.vb文件中的设置以使用这些类。

Answer 10

我的解决scheme有点肮脏，但它按预期工作。 我们的想法是分配所有IdentityResult对象结果在注册新用户时所带来的错误：

 var result = await UserManager.CreateAsync(user, model.Password); 

我们将创build一个新的。 首先，我们需要创build一个包含我们自定义错误的List：

 var erroresEspanol = new List<string>(); 

然后，我们需要遍历结果中的错误，并为每个错误添加一个新的自定义错误，具体取决于错误原因（重复的用户，电子邮件等）：

 foreach (var error in result.Errors) { if (error == ("Name " + model.Usuario + " is already taken.")) { erroresEspanol.Add("El Usuario " + model.Usuario + " ya existe."); } if (error.Substring(0, error.IndexOf(" ")) == "Email") { erroresEspanol.Add("El Email " + model.Email + " ya fue ingresado."); } if (error.Substring(0, error.IndexOf(" ")) == "Passwords") { erroresEspanol.Add("La contraseña debe contener mayúscula, minúscula y al menos 6 caracteres de longitud."); } } 

所以之后我们只需要创build一个新的IdentityResult对象：

 var resultado = new IdentityResult(erroresEspanol); 

并将其传递给我们注册操作结束时的AddErrors方法：

 AddErrors(resultado); 

Answer 11

遇到同样的问题，可以提供自己的资源文件来实现这一点。 当然这需要一点反思黑客！ 首先，您需要以完全安全的方式运行，即在web.config中设置：

 <system.web> <securityPolicy> <trustLevel name="Full" policyFile="internal"/> </securityPolicy> ... 

接下来在您的应用程序中启动代码：

 var ass = Assembly.Load("Microsoft.AspNet.Identity.Core, Version=2.0.0.0, Culture=neutral, PublicKeyToken=31bf3856ad364e35"); Type hack = ass.GetType("Microsoft.AspNet.Identity.Resources"); var field = hack.GetField("resourceMan", BindingFlags.Static | BindingFlags.NonPublic); // NOTE: this is where you set you own resource manager! field.SetValue(null, new global::System.Resources.ResourceManager("WebApplication1.Resources", typeof(WebApplication1.Resources).Assembly)); 

任务完成！
