如何在 .net 5 web API 中添加语言本地化

Question

I have tried to follow the steps of this tutorial to Apply Language localization at my API level. but what ever the HTTP request Header is, it alwase brings the default Language. this is the startup Code, in ConfigureServices method:

  #region Localiztion
        services.AddLocalization();
        services.AddRequestLocalization(x =>
        {
            x.DefaultRequestCulture = new RequestCulture("en");

            x.ApplyCurrentCultureToResponseHeaders = true;

            x.SupportedCultures = new List<CultureInfo> {
                new("ar"),
                new("en") 
            };

             x.SupportedUICultures = new List<CultureInfo> {
                new("ar"),
                new("en")
            };

        });
        #endregion

at Configure method :

  app.UseRequestLocalization();

I have tried to add culture header as mentioned in the tutorial or adding Content-Language header as mentioned on Microsoft Docs but still, it only brings the default whatever the default is.

经过一番研究，与本地化一起使用的 HTTP 标头是Accept-Language 。
