Come localizzare i messaggi di errore UserName e Password di Id quadro ASP.NET?

È ansible fornire stringhe localizzate per i messaggi di errore “sistema” ASP.NET Identity v1, ad esempio ” Nome XYZ già acquisito ” o ” Nome utente XYZ non valido, può contenere solo lettere o cifre “?

Non ancora, abbiamo un bug che tiene traccia di questo elemento di lavoro per consentire di specificare da dove provengono le risorse.

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

Creare una class che eredita IdentityErrorDescriber e sovrascrivere i messaggi di errore desiderati.

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')." }; } } 

Nella class Startup, registrare CustomDescriber personalizzato all’interno di ConfigureServices:

 services.AddIdentity() .AddErrorDescriber(); // Add this line 

AGGIORNAMENTO: qui sotto puoi trovare le versioni già tradotte per spagnolo e portoghese. Raddoppiali!

 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')." }; } } 

Portoghese: (molte grazie a furlanrapha )

 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')." }; } } 

A partire dalla versione 2 dell’identity framework rilasciata il 20 marzo 2014 ora è ansible avere messaggi di errore localizzati.

Prima installa il pacchetto localizzato dell’identity framework.

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

Quindi è necessario impostare la cultura corretta per ottenere messaggi localizzati, ad esempio un modo per impostare la cultura è in web.config

    

Ho incontrato lo stesso problema e ho trovato una soluzione rapida e sporca. Ho esaminato l’assembly Microsoft.AspNet.Identity.Core utilizzando DotPeek (presumo che qualsiasi decompilatore C # lo farà) e ho trovato due classi che sono responsabili di tali messaggi:

  • Microsoft.AspNet.Identity.UserValidator (correlato a UserName)
  • Microsoft.AspNet.Identity.MinimumLengthValidator (relativo alla password)

Queste classi non contengono riferimenti esterni (oltre alle risorse stringa che si desidera sostituire in ogni caso), quindi la loro implementazione nel proprio codice dovrebbe essere abbastanza semplice.

Dopo averlo fatto, non dimenticare di usarli correttamente nel tuo UserManager :

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

Soluzione ASP NET Core (25.11.2016)

È ansible inserire IStringLocalizer in IdentityErrorDescriber personalizzato

1) Crea personalizzato IdentityErrorDescriber (vedi risposta di Gerardo Grignoli)

 public class MultilanguageIdentityErrorDescriber : IdentityErrorDescriber { private readonly IStringLocalizer _localizer; public MultilanguageIdentityErrorDescriber(IStringLocalizer 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) Registra MultilanguageIdentityErrorDescriber in Startup.cs

 services.AddIdentity() .AddErrorDescriber() .AddDefaultTokenProviders(); 

3) Aggiungi messaggi di errore a SharedResource.language.resx.

Il metodo di 1AmirJalali funziona perfettamente. Mentre l’impostazione della cultura in web.config funziona, può essere impostata dynamicmente anche se richiesto, ecco come è ansible ottenerlo:

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

Nell’esempio di codice sopra, cultureName, è il nome della cultura da impostare. Un elenco di culture può essere trovato sotto la voce “Note” qui: http://msdn.microsoft.com/en-us/library/system.globalization.cultureinfo%28v=vs.80%29.aspx

Spero che questo ti aiuti.

Non voglio sovrascrivere la logica (cioè reinventare la ruota), né voglio passare a ASP NET Core. Tutto quello che voglio fare è sovrascrivere i messaggi di errore e utilizzare più file di risorse (per lingua) per personalizzare l’esperienza utente nella lingua scelta.

Ecco la mia soluzione:

  1. Ho creato un file di risorse ‘IdentityErrors.resx’ con il seguente:

      An unknown failure has occured.   Email '{0}' is already taken.   Name {0} is already taken.   A user with that external login already exists.   Email '{0}' is invalid.   Invalid token.   User name {0} is invalid, can only contain letters or digits.   Lockout is not enabled for this user.   No IUserTokenProvider is registered.   No IUserTwoFactorProvider for '{0}' is registered.   Incorrect password.   Passwords must have at least one digit ('0'-'9').   Passwords must have at least one lowercase ('a'-'z').   Passwords must have at least one non letter or digit character.   Passwords must have at least one uppercase ('A'-'Z').   Passwords must be at least {0} characters.   {0} cannot be null or empty.   Role {0} does not exist.   Store does not implement IQueryableRoleStore<TRole>.   Store does not implement IQueryableUserStore<TUser>.   Store does not implement IUserClaimStore<TUser>.   Store does not implement IUserConfirmationStore<TUser>.   Store does not implement IUserEmailStore<TUser>.   Store does not implement IUserLockoutStore<TUser>.   Store does not implement IUserLoginStore<TUser>.   Store does not implement IUserPasswordStore<TUser>.   Store does not implement IUserPhoneNumberStore<TUser>.   Store does not implement IUserRoleStore<TUser>.   Store does not implement IUserSecurityStampStore<TUser>.   Store does not implement IUserTwoFactorStore<TUser>.   User already has a password set.   User already in role.   UserId not found.   User {0} does not exist.   User is not in role.  
  2. Ho creato una class ‘IdentityResultErrorMessages.cs’:

     public class IdentityResultErrorMessages { public static List GetResourceEquivalent(IEnumerable errors) { List errorList = new List(); if (errors != null) { foreach (String error in errors) { if (error.StartsWith("An unknown failure has occured.")) { errorList.Add(IdentityErrors.DefaultError); } else if (error.StartsWith("Email '") && error.EndsWith("' is already taken.")) { errorList.Add(String.Format(IdentityErrors.DuplicateEmail, error.Replace("Email '", "").Replace("' is already taken.", ""))); } else if (error.StartsWith("Name ") && error.EndsWith(" is already taken.")) { errorList.Add(String.Format(IdentityErrors.DuplicateName, error.Replace("Name ", "").Replace(" is already taken.", ""))); } else if (error.StartsWith("A user with that external login already exists.")) { errorList.Add(IdentityErrors.ExternalLoginExists); } else if (error.StartsWith("Email '") && error.EndsWith("' is invalid.")) { errorList.Add(String.Format(IdentityErrors.InvalidEmail, error.Replace("Email '", "").Replace("' is invalid.", ""))); } else if (error.StartsWith("Invalid token.")) { errorList.Add(IdentityErrors.InvalidToken); } else if (error.StartsWith("User name ") && error.EndsWith(" is invalid, can only contain letters or digits.")) { errorList.Add(String.Format(IdentityErrors.InvalidUserName, error.Replace("User name ", "").Replace(" is invalid, can only contain letters or digits.", ""))); } else if (error.StartsWith("Lockout is not enabled for this user.")) { errorList.Add(IdentityErrors.LockoutNotEnabled); } else if (error.StartsWith("No IUserTokenProvider is registered.")) { errorList.Add(IdentityErrors.NoTokenProvider); } else if (error.StartsWith("No IUserTwoFactorProvider for '") && error.EndsWith("' is registered.")) { errorList.Add(String.Format(IdentityErrors.NoTwoFactorProvider, error.Replace("No IUserTwoFactorProvider for '", "").Replace("' is registered.", ""))); } else if (error.StartsWith("Incorrect password.")) { errorList.Add(IdentityErrors.PasswordMismatch); } else if (error.StartsWith("Passwords must have at least one digit ('0'-'9').")) { errorList.Add(IdentityErrors.PasswordRequireDigit); } else if (error.StartsWith("Passwords must have at least one lowercase ('a'-'z').")) { errorList.Add(IdentityErrors.PasswordRequireLower); } else if (error.StartsWith("Passwords must have at least one non letter or digit character.")) { errorList.Add(IdentityErrors.PasswordRequireNonLetterOrDigit); } else if (error.StartsWith("Passwords must have at least one uppercase ('A'-'Z').")) { errorList.Add(IdentityErrors.PasswordRequireUpper); } else if (error.StartsWith("Passwords must be at least ") && error.EndsWith(" characters.")) { errorList.Add(String.Format(IdentityErrors.PasswordTooShort, error.Replace("Passwords must be at least ", "").Replace(" characters.", ""))); } else if (error.EndsWith(" cannot be null or empty.")) { errorList.Add(String.Format(IdentityErrors.PropertyTooShort, error.Replace(" cannot be null or empty.", ""))); } else if (error.StartsWith("Role ") && error.EndsWith(" does not exist.")) { errorList.Add(String.Format(IdentityErrors.RoleNotFound, error.Replace("Role ", "").Replace(" does not exist.", ""))); } else if (error.StartsWith("Store does not implement IQueryableRoleStore")) { errorList.Add(IdentityErrors.StoreNotIQueryableRoleStore); } else if (error.StartsWith("Store does not implement IQueryableUserStore")) { errorList.Add(IdentityErrors.StoreNotIQueryableUserStore); } else if (error.StartsWith("Store does not implement IUserClaimStore")) { errorList.Add(IdentityErrors.StoreNotIUserClaimStore); } else if (error.StartsWith("Store does not implement IUserConfirmationStore")) { errorList.Add(IdentityErrors.StoreNotIUserConfirmationStore); } else if (error.StartsWith("Store does not implement IUserEmailStore")) { errorList.Add(IdentityErrors.StoreNotIUserEmailStore); } else if (error.StartsWith("Store does not implement IUserLockoutStore")) { errorList.Add(IdentityErrors.StoreNotIUserLockoutStore); } else if (error.StartsWith("Store does not implement IUserLoginStore")) { errorList.Add(IdentityErrors.StoreNotIUserLoginStore); } else if (error.StartsWith("Store does not implement IUserPasswordStore")) { errorList.Add(IdentityErrors.StoreNotIUserPasswordStore); } else if (error.StartsWith("Store does not implement IUserPhoneNumberStore")) { errorList.Add(IdentityErrors.StoreNotIUserPhoneNumberStore); } else if (error.StartsWith("Store does not implement IUserRoleStore")) { errorList.Add(IdentityErrors.StoreNotIUserRoleStore); } else if (error.StartsWith("Store does not implement IUserSecurityStampStore")) { errorList.Add(IdentityErrors.StoreNotIUserSecurityStampStore); } else if (error.StartsWith("Store does not implement IUserTwoFactorStore")) { errorList.Add(IdentityErrors.StoreNotIUserTwoFactorStore); } else if (error.StartsWith("User already has a password set.")) { errorList.Add(IdentityErrors.UserAlreadyHasPassword); } else if (error.StartsWith("User already in role.")) { errorList.Add(IdentityErrors.UserAlreadyInRole); } else if (error.StartsWith("UserId not found.")) { errorList.Add(IdentityErrors.UserIdNotFound); } else if (error.StartsWith("User ") && error.EndsWith(" does not exist.")) { errorList.Add(String.Format(IdentityErrors.UserNameNotFound, error.Replace("User ", "").Replace(" does not exist.", ""))); } else if (error.StartsWith("User is not in role.")) { errorList.Add(IdentityErrors.UserNotInRole); } } } return errorList; } } 
  3. Ho modificato il metodo AddErrors del controller al seguente:

     private void AddErrors(IdentityResult result) { foreach (var error in IdentityResultErrorMessages.GetResourceEquivalent(result.Errors)) { ModelState.AddModelError("", error); } } 

Ora, posso creare file di risorse per l’altro contenuto linguistico che voglio pubblicare sul mio sito web.

Questo problema mi ha infastidito già da un po ‘di tempo, quindi ho cercato di inventare qualcosa di generico, perché la soluzione con l’installazione di Identity.Core per una particolare cultura funziona solo se il pacchetto è disponibile a tutti 🙂

Ecco i passaggi su come ho raggiunto la corretta localizzazione:

  1. Ha esaminato l’implementazione di Microsoft.AspNet.Identity.PasswordValidator utilizzando dotPeak, che viene utilizzato per impostazione predefinita in ApplicationUserManager ,
  2. Poi sono arrivato con la mia implementazione della class CustomPasswordValidator : PasswordValidator e sovrascrivere il metodo ValidateAsync per non restituire IdentityResult con i messaggi di errore, ma piuttosto con “codici” di questi messaggi di errore tutti prefissati con la stringa “CustomValidator”.
  3. Quindi in AccountController ho modificato AddErrors che viene richiamato dal post Register per fornire messaggi di errore localizzati dai miei file di risorse personali in base ai codici di errore.

Ecco CustomPasswordValidator e class di utilità PasswordValidatorCodes contenenti codici di errore e metodo per recuperare i messaggi di errore localizzati basati su questi codici (AccountStrings è un file di risorse):

 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 ValidateAsync(string item) { if (item == null) throw new ArgumentNullException("item"); var list = new List(); 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)); } } 

Ed ecco il metodo AccountController.AddErrors modificato. Come puoi vedere, aggiungo un errore al modello per la proprietà Password perché se la Password non supera la convalida, desidero che il messaggio di errore venga visualizzato dal campo Password e non nel riepilogo di convalida. Questo è l’unico motivo per cui il mio CustomPasswordValidator genera codici di errore piuttosto che messaggi di errore direttamente:

 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); } } 

Ultimo ma non meno importante, non dimenticare di modificare il file IdentityConfig , cioè:

 manager.PasswordValidator = new CustomPasswordValidator(); 

AGGIORNARE:

Solo ora ho notato che Marselus Chia (vedi altre risposte) ha trovato la soluzione simile ma per il VB.

Permettetemi di condividere con voi quello che ho fatto per realizzare questo in spagnolo. Lì puoi personalizzare facilmente i messaggi!

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.
"); Errores = Errores.Replace("Passwords must be at least 6 characters.", "- La clave debe contener por lo menos 6 caracteres.
"); 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.
"); Errores = Errores.Replace("Passwords must have at least one digit ('0'-'9').", "- La clave debe contener al menos un dígito (entre 0 y 9).
"); Errores = Errores.Replace("Passwords must have at least one uppercase ('A'-'Z').", "- La clave debe contener al menos una letra (entre A y Z).
"); ErrorMessage.Text = "Errores:

" + Errores;

La mia soluzione è di creare una nuova class di convalida della password personalizzata ereditata da Microsoft.AspNet.Identity.PasswordValidator, sovrascrive ValidateAsync, che è quello che invia il messaggio di errore. Personalizza il messaggio di errore qui e funziona per me …

Queste classi presumono che tu abbia un validatore di nomi di file di risorse globali. Lo script di questa class e l’esempio del file di risorse possono essere trovati qui Identity framework ASP.NET – Codice di esempio Codeplex

Ecco il mio esempio di codice di lavoro in vb.net


 Imports System.Threading.Tasks Imports Microsoft.AspNet.Identity Namespace MyNameSpace Public Class MyPasswordValidator Inherits PasswordValidator Public Overrides Function ValidateAsync(item As String) As Task(Of IdentityResult) Dim errorMessage As String = String.Empty Dim bolminChar As Boolean = True Dim bolminDigit As Boolean = True Dim bolminLcase As Boolean = True Dim bolminUCase As Boolean = True Dim bolminNonAlfanum As Boolean = True If Not String.IsNullOrWhiteSpace(item) AndAlso item.Length >= Me.RequiredLength Then bolminChar = True Else bolminChar = False errorMessage = String.Format(CultureInfo.CurrentCulture, Resources.validator.PasswordTooShort & "
", RequiredLength) End If If Me.RequireDigit Then Dim regex As New Regex("^(?=.*\d).+$") Dim match As Match = regex.Match(item) If match.Success Then bolminDigit = True Else bolminDigit = False errorMessage &= Resources.validator.PasswordRequireDigit & ".
" End If End If If Me.RequireLowercase Then Dim LCrex As New Regex("^(?=.*[az]).+$") Dim LCMatch As Match = LCrex.Match(item) If LCMatch.Success Then bolminLcase = True Else bolminLcase = False errorMessage &= Resources.validator.PasswordRequireLower & "
" End If End If If Me.RequireNonLetterOrDigit Then Dim NAFRex As New Regex("^(?=.*[-+_!@#$%=^\[\]\{\}()&*.,?]).+$") Dim NAFMatch As Match = NAFRex.Match(item) If NAFMatch.Success Then bolminNonAlfanum = True Else bolminNonAlfanum = False errorMessage &= Resources.validator.PasswordRequireNonLetterOrDigit & "
" End If End If If Me.RequireUppercase Then Dim UCrex As New Regex("^(?=.*[AZ]).+$") Dim UCMatch As Match = UCrex.Match(item) If UCMatch.Success Then bolminUCase = True Else bolminUCase = False errorMessage &= Resources.validator.PasswordRequireUpper & "
" End If End If If bolminChar And bolminDigit And bolminLcase And bolminNonAlfanum And bolminUCase Then Return Task.FromResult(Of IdentityResult)(IdentityResult.Success) Else Return Task.FromResult(Of IdentityResult)(IdentityResult.Failed(New String() {errorMessage})) End If 'Return MyBase.ValidateAsync(item) End Function End Class Public Class MyUserValidator Inherits UserValidator(Of applicationUser, int64) Private _manager As ApplicationUserManager Public Sub New(manager As ApplicationUserManager) MyBase.New(manager) _manager = manager End Sub Public Overrides Function ValidateAsync(item As applicationUser) As Task(Of IdentityResult) If item Is Nothing Then Throw New ArgumentNullException("item") End If Dim errors As New List(Of String)() Validateusername(item, errors) If Me.RequireUniqueEmail Then ValidateEmail(item, errors) End If If errors.Count > 0 Then Return Task.FromResult(Of IdentityResult)(IdentityResult.Failed(errors.ToArray())) End If Return Task.FromResult(Of IdentityResult)(IdentityResult.Success) End Function Private Sub Validateusername(User As applicationUser, errors As List(Of String)) If String.IsNullOrWhiteSpace(User.UserName) Then errors.Add(String.Format(CultureInfo.CurrentCulture, Resources.validator.PropertyTooShort, "Email")) ' ElseIf Me.AllowOnlyAlphanumericUserNames AndAlso Not Regex.IsMatch(User.UserName, "^[A-Za-z0-9@_\.]+$") Then ' If any characters are not letters or digits, its an illegal user name errors.Add(String.Format(CultureInfo.CurrentCulture, Resources.validator.InvalidUserName, User.UserName)) Else Dim owner = _manager.FindByName(User.UserName) If owner IsNot Nothing AndAlso Not EqualityComparer(Of applicationUser).ReferenceEquals(owner.Id, User.Id) Then errors.Add(String.Format(CultureInfo.CurrentCulture, Resources.validator.DuplicateName, User.UserName)) End If End If End Sub Private Sub ValidateEmail(User As ApplicationUser, errors As List(Of String)) Dim email As String = String.Empty If User.Id > 0 Then email = _manager.GetEmail(User.Id) End If If String.IsNullOrWhiteSpace(email) Then errors.Add(String.Format(CultureInfo.CurrentCulture, Resources.validator.PropertyTooShort, "Email")) Return End If Try Dim m As New MailAddress(email) Catch ex As Exception errors.Add(String.Format(CultureInfo.CurrentCulture, Resources.validator.InvalidEmail, email)) Return End Try Dim owner = _manager.FindByEmail(email) If owner IsNot Nothing AndAlso Not EqualityComparer(Of ApplicationUser).ReferenceEquals(owner.Id, User.Id) Then errors.Add(String.Format(CultureInfo.CurrentCulture, Resources.validator.DuplicateName, email)) End If End Sub End Class

Remember to update the setting in your identityConfig.vb file to used these class.

My solution was a little bit dirty but It works as expected. The idea is to assign all the errors that the IdentityResult object result brings when we register a new user:

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

To a new one that we will create. First, we need to create a List that will contain our custom errors:

 var erroresEspanol = new List(); 

Then, we need to iterate trough the errors inside result and add a new custom error for every one of them depending on which was the cause of it (Duplicate user, email, etc.):

 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."); } } 

So after that we just create a new IdentityResult object:

 var resultado = new IdentityResult(erroresEspanol); 

And pass it to the AddErrors method at the end of our Register action:

 AddErrors(resultado); 

Having come across the same problem one can provide your own resource files to achieve this. Of course it requires a bit of reflection hacking! First you will need to be running with full security, ie set in your web.config:

     ... 

Next in your app start up code:

 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)); 

Lavoro fatto!

Here is Gerardo Grignoli’s answer with French translation

 ///  ///  /// Service to enable localization (french) for application facing identity errors. ///  public class FrenchIdentityErrorDescriber : IdentityErrorDescriber { ///  public override IdentityError DefaultError() => new IdentityError { Code = nameof(DefaultError), Description = "Une erreur inconnue est survenue." }; ///  public override IdentityError ConcurrencyFailure() => new IdentityError { Code = nameof(ConcurrencyFailure), Description = "Erreur de concurrence simultanée optimiste, l'objet a été modifié." }; ///  public override IdentityError PasswordMismatch() => new IdentityError { Code = nameof(PasswordMismatch), Description = "Mot de passe incorrect." }; ///  public override IdentityError InvalidToken() => new IdentityError { Code = nameof(InvalidToken), Description = "Jeton invalide." }; ///  public override IdentityError LoginAlreadyAssociated() => new IdentityError { Code = nameof(LoginAlreadyAssociated), Description = "Un utilisateur avec ce nom de compte existe déjà." }; ///  public override IdentityError InvalidUserName(string userName) => new IdentityError { Code = nameof(InvalidUserName), Description = $"Le nom de compte '{userName}' est invalide.

I managed to find a solution to create localized version of AspNet.Identity for cultures that no ready-to-use package is available for. Steps are:

  1. Download the source code from GitHub and open the src/Microsoft.AspNet.Identity.Core project in visual studio.
  2. Add a new item (Resource file) to the project. Name it Resources.aa-BB.resx which aa-BB is the culture you need to localize the assembly for. eg.: Resources.fa-IR.resx .
  3. Open the new created file and copy resource items from Resources.resx to it.
  4. Localize the texts as you want.
  5. Costruisci il progetto.
  6. Go to the bin folder and under the Debug or Release directory you will see a folder named aa-BB (the culture you entered before). Copy the folder to the bin directory of your project.
  7. Make the changes that @1AmirJalali said ( this post ).
  8. Well done! Localization is complete. Try to share your localized package 🙂

Hi Here My Solution to to translate identity errors:

  public string TranslateIdentityResult(string massage) { var list = new List>() { new KeyValuePair("An unknown failure has occured.", "حدث خطأ غير معروف"), new KeyValuePair("Email '{0}' is already taken.", "هذا البريد '{0}' موجود بالفعل"), new KeyValuePair("Name {0} is already taken.", "الاسم {0} مأخوذ بالفعل."), new KeyValuePair("A user with that external login already exists.", "يوجد بالفعل مستخدم له معلومات تسجيل الدخول الخارجية."), new KeyValuePair("Email '{0}' is invalid.", "البريد الإلكتروني '{0}' غير صحيح."), new KeyValuePair("Invalid token.", "المفتاح غير صالح"), new KeyValuePair("User name {0} is invalid, can only contain letters or digits.", "اسم المستخدم {0} غير صالح ، يمكن أن يحتوي فقط على أحرف أو أرقام."), new KeyValuePair("Lockout is not enabled for this user.", "تأمين المستخدم غير متاح لهذا المستخدم"), new KeyValuePair("Incorrect password.", "الرقم السري غير صحيح"), new KeyValuePair("Passwords must have at least one digit ('0'-'9').", "الرقم السري يجب أ،ن يحتوي على الأقل رقم واحد (0-9)"), new KeyValuePair("Passwords must have at least one lowercase ('a'-'z').", "يجب أن تحتوي كلمات المرور على حرف صغير واحد على الأقل ('a' - 'z')."), new KeyValuePair("Passwords must have at least one non letter or digit character.", "يجب أن يكون لكلمة مرور حرف واحد على الأقل غير الحرف أو الرقم."), new KeyValuePair("Passwords must have at least one uppercase ('A'-'Z').", "يجب أن تحتوي كلمات المرور على حرف كبير واحد على الأقل ('A' - 'Z')."), new KeyValuePair("Passwords must be at least {0} characters.", "يجب أن تكون كلمات المرور على الأقل {0} حرفًا."), new KeyValuePair("{0} cannot be null or empty.", "لا يمكن أن يكون {0} خاليًا أو فارغًا."), new KeyValuePair("Role {0} does not exist.", "صلاحية {0} غير موجود."), new KeyValuePair("User already has a password set.", "المستخدم لديه بالفعل كلمة مرور محددة."), new KeyValuePair("User already in role.", "المستخدم بالفعل لديه هذي الصلاحية."), new KeyValuePair("UserId not found.", "لم يتم العثور على هوية المستخدم."), new KeyValuePair("User {0} does not exist.", "المستخدم {0} غير موجود."), new KeyValuePair("User is not in role.", "المستخدم ليس لديه صلاحية.") }; return list.Find(x => x.Key.Equals(massage)).Value; } 

  private void AddErrors(IdentityResult result) { foreach (var error in result.Errors) { //if my function is not found error it will print it as it's foreach(var msg in error.Split('.')) { ModelState.AddModelError("", accBClass.TranslateIdentityResult(msg.TrimStart(' ')) ?? msg); } } }
