如何在ASP.NET Core中本地化验证属性的标准错误消息 [英] How to localize standard error messages of validation attributes in ASP.NET Core

问题描述

如何在ASP.NET Core(v2.2)中本地化验证属性的标准错误消息?例如， [Required] 属性具有以下错误消息:" xxx字段为必填字段.". [EmailAddress] 具有" xxx字段不是有效的电子邮件地址."； [比较] 具有"'xxx'和'yyy'不匹配."，依此类推.在我们的项目中，我们不使用英语，我想找到一种方法来翻译标准错误消息，而又不直接将它们写在每个数据模型类的每个属性中

How to localize standard error messages of validation attributes in ASP.NET Core (v2.2)? For Example, [Required] attribute has this error message "The xxx field is required."; [EmailAddress] has "The xxx field is not a valid e-mail address."; [Compare] has "'xxx' and 'yyy' do not match." and so on. In our project we use not English language and I want to find a way how to translate standard error messages without writing them directly in every attribute of every data-model class

推荐答案

这在

This is spelled out in the docs. You can do either:

1. 在属性上使用ResourcePath选项.

[Required(ResourcePath = "Resources")]

然后，将本地化的消息添加到Resources/Namespace.To.MyClass.[lang].resx.

Then, you'd add the localized message to Resources/Namespace.To.MyClass.[lang].resx.

对所有类使用一个资源文件:

Use one resource file for all classes:

public void ConfigureServices(IServiceCollection services)
{
    services.AddMvc()
        .AddDataAnnotationsLocalization(options => {
            options.DataAnnotationLocalizerProvider = (type, factory) =>
                factory.Create(typeof(SharedResource));
        });
}
