I have implemented localization in .Net Core 3.1 as per https://docs.microsoft.com/en-us/aspnet/core/fundamentals/localization?view=aspnetcore-3.1. It's working fine on local using QueryString & Accept-Language HTTP header on local but after deployment not working with Accept-Language HTTP header for other cultures except english. Code Changes
- In Startup.cs
// in ConfigureServices
services.AddRazorPages()
.AddViewLocalization(LanguageViewLocationExpanderFormat.Suffix)
.AddDataAnnotationsLocalization()
services.AddLocalization(options => options.ResourcesPath = "Resources");
services.Configure<RequestLocalizationOptions>(options =>
{
var supportedCultures = GetSupportedCultures();
options.DefaultRequestCulture = new RequestCulture("en");
options.SupportedCultures = supportedCultures;
options.SupportedUICultures = supportedCultures;
});
// in configure method
app.UseRequestLocalization(app.ApplicationServices.GetService<IOptions<RequestLocalizationOptions>>().Value);
// helper method
private IList<CultureInfo> GetSupportedCultures()
{
var cultures = Configuration.GetValue<string>("SupportedCultures")?.Split(",");
var supportedCultures = new List<CultureInfo>();
foreach (var culture in cultures)
{
supportedCultures.Add(new CultureInfo(culture.Trim()));
}
return supportedCultures;
}
// in appsettings.json
"SupportedCultures": "en,fr,de,el,es"
Request Header in browser network tab
Accept-Language: fr-FR,fr-CA;q=0.9,fr;q=0.8,de;q=0.7,en;q=0.6,es;q=0.5,el;q=0.4,en-GB;q=0.3,en-US;q=0.2
