我有一个使用资源本地化的ASP.NET Core MVC应用程序.它目前只支持一种文化(fa-IR),我希望根据这种文化处理所有本地化.在ASP.NET Core 1.1中我没有任何问题,但在从ASP.NET Core 1.1迁移到2.1后,我看到每个HTTP请求的此警告:

AcceptLanguageHeaderRequestCultureProvider返回以下不受支持的文化'en-US,en,fa'.

这是我的初创公司:

public class Startup
{
    protected CultureInfo DefaultCultureInfo { get; private set; } = new CultureInfo("fa-IR");

    public void ConfigureServices(IServiceCollection services)
    {
        CultureInfo.DefaultThreadCurrentCulture = DefaultCultureInfo;
        CultureInfo.DefaultThreadCurrentUICulture = DefaultCultureInfo;
        services.AddLocalization(options => { options.ResourcesPath = "Resources"; });

        services.AddMemoryCache();
        services.AddSession();

        services.AddMvc()
        .AddDataAnnotationsLocalization()
        .AddViewLocalization()
        .AddControllersAsServices()
        .SetCompatibilityVersion(CompatibilityVersion.Version_2_1)
        .AddSessionStateTempDataProvider();

        services.Configure<RequestLocalizationOptions>(options =>
        {
            var supportedCultures = new[] { new CultureInfo("fa-IR"), new CultureInfo("en-US") };
            options.DefaultRequestCulture = new RequestCulture("fa-IR", "fa-IR");
            options.SupportedCultures = supportedCultures;
            options.SupportedUICultures = supportedCultures;

            options.RequestCultureProviders.Insert(0, new CustomRequestCultureProvider(async context =>
            { …
