如何使用默认本地化创建 SharedResource class 进行本地化

How to create a SharedResource class for localization with default localization

ConfigureServices 我做了:

services.AddLocalization(opts => opts.ResourcesPath = "Resources");
services.AddMvc(options => { options.MaxModelValidationErrors = 10; })
    .AddViewLocalization(LanguageViewLocationExpanderFormat.Suffix,
        opts => opts.ResourcesPath = "Resources")
    .AddDataAnnotationsLocalization(options =>
    {
        options.DataAnnotationLocalizerProvider = (type, factory) =>
        {
            var assemblyName = new AssemblyName(typeof(SharedResource).GetTypeInfo().Assembly.FullName);
            return factory.Create("SharedResource", assemblyName.Name);
        };
    });

services.Configure<RequestLocalizationOptions>(options =>
{
    var supportedCultures = new[]
    {
            new CultureInfo("en-US"),
            new CultureInfo("en"),
            new CultureInfo("it-IT"),
            new CultureInfo("it")
    };

    options.DefaultRequestCulture = new RequestCulture(culture: "en", uiCulture: "en");
    options.SupportedCultures = supportedCultures;
    options.SupportedUICultures = supportedCultures;
    options.RequestCultureProviders.Insert(0, new AcceptLanguageHeaderRequestCultureProvider());
});

//This is the custom service for localization
services.AddSingleton<LocService>();

LocService 中创建了本地化服务,例如:

public class LocService : StringLocalizer<string>
{
    private readonly IStringLocalizer _localizer;

    public LocService(IStringLocalizerFactory factory) : base(factory)
    {
        var type = typeof(SharedResource);
        var assemblyName = new AssemblyName(type.GetTypeInfo().Assembly.FullName);
        _localizer = factory.Create("SharedResource", assemblyName.Name);
    }

    public override LocalizedString this[string name]
    {
        get => _localizer[name];
    }
}

并配置 Configure() 中的所有内容,例如:

var locOptions = app.ApplicationServices.GetService<IOptions<RequestLocalizationOptions>>();
app.UseRequestLocalization(locOptions.Value);

在视图中我将其注入为:

@inject LocService Loc
@Loc["wordToTranslate"]

我的问题是这种方法在缺少相关资源文件时不起作用,例如, 如果我没有 Resources/SharedResource.it.resx 并且调用 (@Loc["wordToTranslate"]) 只是 returns "wordToTranslate" 即使在默认情况下 Resources/SharedResource。 en.resx 对应另一个字符串 ("wordToTranslate" = "Success")。我做错了什么?

在 ASP.NET 核心本地化中,默认语言是您放在括号内的语言,因此:

@Localizer["some text"]

将呈现:

  • "some text",因为当前语言是默认语言
  • "some text",因为没有当前语言的资源文件
  • 翻译,假设有当前语言的资源文件

或者,如果您想使用资源文件,只需从中删除文化,即 someresource.resx
