疑問に思っている人のために、現在選択されている文化のメッセージをローカライズすることが可能であれば、可能です. asp.netコア2.2では、 LocalizedIdentityErrorDescriberクラスを作成できます。ここで、IdentityResourcesはダミークラスの名前です(ここで説明されています:グローバリゼーションとローカリゼーション):

次に、次のように言語のリソース ファイルを作成します: Resources\(上記のダミー クラスの名前)(.culture).resx。デフォルトの言語カルチャは空白のままにする必要があります。「。」を忘れないでください。デフォルトでない場合はカルチャ名の前。IdentityResources ファイルは次のようになります。
Startup.cs に次の行を追加します。
public void ConfigureServices(IServiceCollection services)
{
services.AddLocalization(opts => { opts.ResourcesPath = "Resources"; });
services.AddIdentity<IdentityUser, IdentityRole>()
.AddEntityFrameworkStores<nameofyourdbcontext>()
.AddDefaultTokenProviders()
.AddErrorDescriber<LocalizedIdentityErrorDescriber>(); // this line is important
services.Configure<RequestLocalizationOptions>(options =>
{
var supportedCultures = new[]
{
new CultureInfo("en"), // english
new CultureInfo("tr"), // turkish
new CultureInfo("ru") // russian
};
options.DefaultRequestCulture = new RequestCulture(culture: "en", uiCulture: "en");
options.SupportedCultures = supportedCultures;
options.SupportedUICultures = supportedCultures;
options.RequestCultureProviders.Insert(0, new CookieRequestCultureProvider()); // type of CultureProvider you want.
});
}
public void Configure(IApplicationBuilder app, IHostingEnvironment env)
{
var localizationOptions = app.ApplicationServices.GetService<IOptions<RequestLocalizationOptions>>();
// IT IS IMPORTANT TO CALL UseRequestLocalization BEFORE UseMvc
app.UseRequestLocalization(localizationOptions.Value);
app.UseMvc(routes =>
{
routes.MapRoute(
name: "default",
template: "{controller=Home}/{action=Index}/{id?}"
);
});
}
ここまででほぼ完了ですが、Culture Cookie を設定する必要があります。コード例はGlobalization and localizationにあります。それが誰かを助けることを願っています。
