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

创建一个继承 IdentityErrorDescriber 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 ErrorDescriber：

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

从 2014 年 3 月 20 日发布的身份版本 2 开始，您现在可以拥有本地化的错误消息。

首先安装身份本地化包。

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

然后必须设置正确的文化以获得本地化消息，例如设置文化的一种方法是在 web.config

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

ASP NET Core 解决方法 (25.11.2016)

您可以将 IStringLocalizer 注入自定义 IdentityErrorDescriber

1）创建自定义 IdentityErrorDescriber （见 Gerardo Grignoli 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) 向 SharedResource.language.resx 添加错误消息。

我遇到了同样的问题，并找到了一个快速而肮脏的解决方法。我Microsoft.AspNet.Identity.Core使用 DotPeek 查看了程序集内部（我假设任何 C# 反编译器都可以）并发现两个负责此类消息的类：

  • Microsoft.AspNet.Identity.UserValidator<TUser>（用户名相关）
  • Microsoft.AspNet.Identity.MinimumLengthValidator（密码相关）

这些类不包含任何外部引用（除了要替换的字符串资源），因此在您自己的代码中重新实现它们应该相当简单。

这样做之后，不要忘记在你的UserManager:

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

1AmirJalali 的方法非常有效。虽然在 web.config 中设置文化有效，但如果需要也可以动态设置，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 是要设置的文化名称。可以在此处的“备注”标题下找到文化列表：http: //msdn.microsoft.com/en-us/library/system.globalization.cultureinfo%28v=vs.80%29.aspx

希望这可以帮助。

根据这里的答案，我为我们基于 MVC Core 2.2 构建的多语言网站制作了自己的实现，其中的字符串不能被硬编码。

我正在使用带有自动生成设计器的基本资源文件来获取字符串，执行此操作的代码如下所示：

public class LocalizedIdentityErrorDescriber : IdentityErrorDescriber
{
    private ResourceManager ResourceManager { get; set; }

    public LocalizedIdentityErrorDescriber()
    {
        ResourceManager = Translations.ResourceManager;
    }

    public override IdentityError DefaultError() { return new IdentityError { Code = nameof(DefaultError), Description = Translations.Validation_DefaultError }; }
    public override IdentityError ConcurrencyFailure() { return new IdentityError { Code = nameof(ConcurrencyFailure), Description = Translations.Validation_ConcurrencyFailure }; }
    public override IdentityError PasswordMismatch() { return new IdentityError { Code = nameof(PasswordMismatch), Description = Translations.Validation_PasswordMismatch }; }
    public override IdentityError InvalidToken() { return new IdentityError { Code = nameof(InvalidToken), Description = Translations.Validation_InvalidToken }; }
    public override IdentityError LoginAlreadyAssociated() { return new IdentityError { Code = nameof(LoginAlreadyAssociated), Description = Translations.Validation_LoginAlreadyAssociated }; }
    public override IdentityError InvalidUserName(string userName) { return new IdentityError { Code = nameof(InvalidUserName), Description = string.Format(Translations.Validation_InvalidUserName, userName) }; }
    public override IdentityError InvalidEmail(string email) { return new IdentityError { Code = nameof(InvalidEmail), Description = string.Format(Translations.Validation_InvalidEmail, email) }; }
    public override IdentityError DuplicateUserName(string userName) { return new IdentityError { Code = nameof(DuplicateUserName), Description = string.Format(Translations.Validation_DuplicateUserName, userName) }; }
    public override IdentityError DuplicateEmail(string email) { return new IdentityError { Code = nameof(DuplicateEmail), Description = string.Format(Translations.Validation_DuplicateEmail, email) }; }
    public override IdentityError InvalidRoleName(string role) { return new IdentityError { Code = nameof(InvalidRoleName), Description = string.Format(Translations.Validation_InvalidRoleName, role) }; }
    public override IdentityError DuplicateRoleName(string role) { return new IdentityError { Code = nameof(DuplicateRoleName), Description = string.Format(Translations.Validation_DuplicateRoleName, role) }; }
    public override IdentityError UserAlreadyHasPassword() { return new IdentityError { Code = nameof(UserAlreadyHasPassword), Description = Translations.Validation_UserAlreadyHasPassword }; }
    public override IdentityError UserLockoutNotEnabled() { return new IdentityError { Code = nameof(UserLockoutNotEnabled), Description = Translations.Validation_UserLockoutNotEnabled }; }
    public override IdentityError UserAlreadyInRole(string role) { return new IdentityError { Code = nameof(UserAlreadyInRole), Description = string.Format(Translations.Validation_UserAlreadyInRole, role) }; }
    public override IdentityError UserNotInRole(string role) { return new IdentityError { Code = nameof(UserNotInRole), Description = string.Format(Translations.Validation_UserNotInRole, role) }; }
    public override IdentityError PasswordTooShort(int length) { return new IdentityError { Code = nameof(PasswordTooShort), Description = string.Format(Translations.Validation_PasswordTooShort, length) }; }
    public override IdentityError PasswordRequiresNonAlphanumeric() { return new IdentityError { Code = nameof(PasswordRequiresNonAlphanumeric), Description = Translations.Validation_PasswordRequiresNonAlphanumeric }; }
    public override IdentityError PasswordRequiresDigit() { return new IdentityError { Code = nameof(PasswordRequiresDigit), Description = Translations.Validation_PasswordRequiresDigit }; }
    public override IdentityError PasswordRequiresLower() { return new IdentityError { Code = nameof(PasswordRequiresLower), Description = Translations.Validation_PasswordRequiresLower }; }
    public override IdentityError PasswordRequiresUpper() { return new IdentityError { Code = nameof(PasswordRequiresUpper), Description = Translations.Validation_PasswordRequiresUpper }; }
}

然后将其集成到 Startup.cs 的身份管道中

services.AddDefaultIdentity<User>()
    .AddErrorDescriber<LocalizedIdentityErrorDescriber>()
    .AddDefaultTokenProviders();

最后，我在 Translations.resx 和子资源文件中定义了字符串，其中的键名为 Validation_DefaultError、Validation_PasswordMismatch 等。

这个问题已经困扰了我很长一段时间，所以我试图想出一些通用的东西，因为为特定文化安装 Identity.Core 的解决方案只有在包完全可用的情况下才有效:)

以下是我如何实现正确本地化的步骤：

  1. Microsoft.AspNet.Identity.PasswordValidator查看了使用默认使用的 dotPeak的实现ApplicationUserManager，
  2. 然后我想出了我自己的实现class CustomPasswordValidator : PasswordValidator并覆盖了该ValidateAsync方法以不返回IdentityResult错误消息，而是返回这些错误消息的“代码”，所有这些错误消息都以“CustomValidator”字符串为前缀。
  3. 然后，AccountController我更改AddErrors了从Register帖子中调用的内容，以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。

下面是包含错误代码和基于这些代码检索本地化错误消息的方法的CustomPasswordValidator实用程序类（AccountStrings 是一个资源文件）：PasswordValidatorCodes

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));
    }
}

这是修改后的AccountController.AddErrors方法。如您所见，我在属性模型中添加了一个错误，Password因为如果Password未通过验证，那么我希望错误消息由Password字段显示，而不是在验证摘要中。CustomPasswordValidator这是我直接产生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);
    }
}

最后但同样重要的是，不要忘记修改IdentityConfig文件，即：

manager.PasswordValidator = new CustomPasswordValidator();

更新：

直到现在我才注意到 Marselus Chia（请参阅其他答案）提出了类似的解决方案，但针对 VB。

我不想重写逻辑（即重新发明轮子），也不想切换到 ASP NET Core。我要做的就是覆盖错误消息并使用多个资源文件（每种语言）来根据他们选择的语言定制用户体验。

        {
          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."))
        {

        }
      }
    }
    return errorList;
  }
}

  3. 我将控制器的 AddErrors 方法更改为以下内容：

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

现在，我可以为我想在我的网站上提供的其他语言内容创建资源文件。

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;

我的解决方案是创建新的自定义密码验证类，继承自 Microsoft.AspNet.Identity.PasswordValidator，覆盖发出错误消息的 ValidateAsync。在此处自定义错误消息，它对我有用...

这些类假定您有一个全局资源文件名验证器。这些类的脚本和资源文件示例可以在这里找到ASP.NET Identity - Codeplex 示例代码

    End Sub
End Class

请记住更新 identityConfig.vb 文件中的设置以使用这些类。

我的解决方案有点脏，但它按预期工作。我们的想法是分配 IdentityResult 对象结果在我们注册新用户时带来的所有错误：

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

到我们将创建的一个新的。首先，我们需要创建一个包含自定义错误的列表：

var erroresEspanol = new List<string>();

然后，我们需要遍历结果中的错误，并根据导致错误的原因（重复用户、电子邮件等）为每个错误添加一个新的自定义错误：

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.");
                }
            }

因此，之后我们只需创建一个新的 IdentityResult 对象：

var resultado = new IdentityResult(erroresEspanol);

并在我们的 Register 操作结束时将其传递给 AddErrors 方法：

AddErrors(resultado);

遇到同样的问题后，您可以提供自己的资源文件来实现这一目标。当然，它需要一些反射黑客！首先，您需要在完全安全的情况下运行，即在您的 web.config 中设置：

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

接下来在您的应用启动代码中：

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！

我设法找到了一种解决方案，为没有现成可用包的文化创建本地化版本的 AspNet.Identity。步骤是：

  1. 从GitHub下载源代码并在 Visual Studio 中打开 src/Microsoft.AspNet.Identity.Core 项目。
  2. 将新项目（资源文件）添加到项目中。Resources.aa-BB.resx将其命名aa-BB为您需要为其本地化程序集的文化。例如：Resources.fa-IR.resx.
  3. 打开新创建的文件并将资源项复制Resources.resx到其中。
  4. 根据需要本地化文本。
  5. 构建项目。
  6. 转到bin文件夹，在DebugorRelease目录下，您将看到一个名为aa-BB（您之前输入的文化）的文件夹。将文件夹复制到bin项目的目录中。
  7. 进行@1AmirJalali 所说的更改（这篇文章）。
  8. 做得好！本地化完成。尝试分享您的本地化包:)
