转换身份密码验证消息
作者：互联网
到目前为止,我已经能够翻译ASP.Net Core 2.1 Web应用程序中的所有内容.
事实证明,这是一个小挑战,因为脚手架的“帐户页面”需要一些设置.
但是我找不到一种翻译密码验证消息的方法.同样,翻译模型绑定消息也是一个小挑战(感谢stackoverflow).
有任何想法吗？
我将Startup.cs文件的相关部分包括在内：
public void ConfigureServices(IServiceCollection services)
{
...
services.AddMvc(options =>
{
var type = typeof(SharedResources);
var assemblyName = new AssemblyName(type.GetTypeInfo().Assembly.FullName);
var factory = services.BuildServiceProvider().GetService<IStringLocalizerFactory>();
var L = factory.Create("SharedResources", assemblyName.Name);
options.ModelBindingMessageProvider.SetValueIsInvalidAccessor(x => L["The value '{0}' is invalid.", x]);
options.ModelBindingMessageProvider.SetValueMustNotBeNullAccessor(x => L["The value '{0}' is invalid.", x]);
options.ModelBindingMessageProvider.SetValueMustBeANumberAccessor(x => L["The field {0} must be a number.", x]);
options.ModelBindingMessageProvider.SetMissingBindRequiredValueAccessor(x => L["A value for the '{0}' property was not provided.", x]);
options.ModelBindingMessageProvider.SetAttemptedValueIsInvalidAccessor((x, y) => L["The value '{0}' is not valid for {1}.", x, y]);
options.ModelBindingMessageProvider.SetMissingKeyOrValueAccessor(() => L["A value is required."]);
options.ModelBindingMessageProvider.SetUnknownValueIsInvalidAccessor(x => L["The supplied value is invalid for {0}.", x]);
options.ModelBindingMessageProvider.SetMissingRequestBodyRequiredValueAccessor(() => L["A non-empty request body is required."]);
options.ModelBindingMessageProvider.SetNonPropertyAttemptedValueIsInvalidAccessor(x => L["The value '{0}' is not valid.", x]);
options.ModelBindingMessageProvider.SetNonPropertyUnknownValueIsInvalidAccessor(() => L["The supplied value is invalid."]);
options.ModelBindingMessageProvider.SetNonPropertyValueMustBeANumberAccessor(() => L["NonPropertyValueMustBeNumber"]);
})
.AddViewLocalization(LanguageViewLocationExpanderFormat.Suffix)
.AddDataAnnotationsLocalization(options =>
{
options.DataAnnotationLocalizerProvider = (type, factory) =>
{
// This is for Account scaffolded pages data annotations
return factory.Create(typeof(SharedResources));
};
});
...
}
我不能在Register.cshtml.cs的InputModel中放置类似的内容,因为ErrorMessage被忽略了(无论如何我都不会这样做,因为我不想对密码策略描述进行硬编码)：
[Required(ErrorMessage = "The {0} field is required.")]
[StringLength(100, ErrorMessage = "The {0} must be at least {2} and at max {1} characters long.", MinimumLength = 6)]
[DataType(DataType.Password, ErrorMessage = "Password must be nice")]
[Display(Name = "Password")]
public string Password { get; set; }
解决方法:
这可以通过本地化身份错误消息来完成,有22条消息必须本地化.
首先,创建一个共享资源文件“其密钥使用public access修饰符定义”,然后键入所有具有本地化版本的错误消息,如下图所示：
然后创建一个实现IdentityErrorDescriber的新类,并参考共享资源文件覆盖所有默认消息；在此示例中,共享资源文件名为LocalizedIdentityErrorMessages：
public class LocalizedIdentityErrorDescriber : IdentityErrorDescriber
{
public override IdentityError DuplicateEmail(string email)
{
return new IdentityError
{
Code = nameof(DuplicateEmail),
Description = string.Format(LocalizedIdentityErrorMessages.DuplicateEmail, email)
};
}
public override IdentityError DuplicateUserName(string userName)
{
return new IdentityError
{
Code = nameof(DuplicateUserName),
Description = string.Format(LocalizedIdentityErrorMessages.DuplicateUserName, userName)
};
}
public override IdentityError InvalidEmail(string email)
{
return new IdentityError
{
Code = nameof(InvalidEmail),
Description = string.Format(LocalizedIdentityErrorMessages.InvalidEmail, email)
};
}
public override IdentityError DuplicateRoleName(string role)
{
return new IdentityError
{
Code = nameof(DuplicateRoleName),
Description = string.Format(LocalizedIdentityErrorMessages.DuplicateRoleName, role)
};
}
public override IdentityError InvalidRoleName(string role)
{
return new IdentityError
{
Code = nameof(InvalidRoleName),
Description = string.Format(LocalizedIdentityErrorMessages.InvalidRoleName, role)
};
}
public override IdentityError InvalidToken()
{
return new IdentityError
{
Code = nameof(InvalidToken),
Description = LocalizedIdentityErrorMessages.InvalidToken
};
}
public override IdentityError InvalidUserName(string userName)
{
return new IdentityError
{
Code = nameof(InvalidUserName),
Description = string.Format(LocalizedIdentityErrorMessages.InvalidUserName, userName)
};
}
public override IdentityError LoginAlreadyAssociated()
{
return new IdentityError
{
Code = nameof(LoginAlreadyAssociated),
Description = LocalizedIdentityErrorMessages.LoginAlreadyAssociated
};
}
public override IdentityError PasswordMismatch()
{
return new IdentityError
{
Code = nameof(PasswordMismatch),
Description = LocalizedIdentityErrorMessages.PasswordMismatch
};
}
public override IdentityError PasswordRequiresDigit()
{
return new IdentityError
{
Code = nameof(PasswordRequiresDigit),
Description = LocalizedIdentityErrorMessages.PasswordRequiresDigit
};
}
public override IdentityError PasswordRequiresLower()
{
return new IdentityError
{
Code = nameof(PasswordRequiresLower),
Description = LocalizedIdentityErrorMessages.PasswordRequiresLower
};
}
public override IdentityError PasswordRequiresNonAlphanumeric()
{
return new IdentityError
{
Code = nameof(PasswordRequiresNonAlphanumeric),
Description = LocalizedIdentityErrorMessages.PasswordRequiresNonAlphanumeric
};
}
public override IdentityError PasswordRequiresUniqueChars(int uniqueChars)
{
return new IdentityError
{
Code = nameof(PasswordRequiresUniqueChars),
Description = string.Format(LocalizedIdentityErrorMessages.PasswordRequiresUniqueChars, uniqueChars)
};
}
public override IdentityError PasswordRequiresUpper()
{
return new IdentityError
{
Code = nameof(PasswordRequiresUpper),
Description = LocalizedIdentityErrorMessages.PasswordRequiresUpper
};
}
public override IdentityError PasswordTooShort(int length)
{
return new IdentityError
{
Code = nameof(PasswordTooShort),
Description = string.Format(LocalizedIdentityErrorMessages.PasswordTooShort, length)
};
}
public override IdentityError UserAlreadyHasPassword()
{
return new IdentityError
{
Code = nameof(UserAlreadyHasPassword),
Description = LocalizedIdentityErrorMessages.UserAlreadyHasPassword
};
}
public override IdentityError UserAlreadyInRole(string role)
{
return new IdentityError
{
Code = nameof(UserAlreadyInRole),
Description = string.Format(LocalizedIdentityErrorMessages.UserAlreadyInRole, role)
};
}
public override IdentityError UserNotInRole(string role)
{
return new IdentityError
{
Code = nameof(UserNotInRole),
Description = string.Format(LocalizedIdentityErrorMessages.UserNotInRole, role)
};
}
public override IdentityError UserLockoutNotEnabled()
{
return new IdentityError
{
Code = nameof(UserLockoutNotEnabled),
Description = LocalizedIdentityErrorMessages.UserLockoutNotEnabled
};
}
public override IdentityError RecoveryCodeRedemptionFailed()
{
return new IdentityError
{
Code = nameof(RecoveryCodeRedemptionFailed),
Description = LocalizedIdentityErrorMessages.RecoveryCodeRedemptionFailed
};
}
public override IdentityError ConcurrencyFailure()
{
return new IdentityError
{
Code = nameof(ConcurrencyFailure),
Description = LocalizedIdentityErrorMessages.ConcurrencyFailure
};
}
public override IdentityError DefaultError()
{
return new IdentityError
{
Code = nameof(DefaultError),
Description = LocalizedIdentityErrorMessages.DefaultIdentityError
};
}
}
最后,将本地化的错误描述器添加到启动类中的ConfigureServices方法下的身份设置中：
services.AddIdentity<AppUser, AppRole>()
// localize identity error messages
.AddErrorDescriber<LocalizedIdentityErrorDescriber>()
.AddEntityFrameworkStores()
.AddDefaultTokenProviders();
