永远相同的文化：en-US

Question

我有一个asp.net核心项目，我想将默认语言设置为nl-BE。出于某种原因，它总是采用en-US语言

请参阅下面的代码（ps：我创建了自己的ApplicationLocalizer，它从数据库中获取资源=＆gt;工作正常）。

Startup.cs

public void ConfigureServices(IServiceCollection services)
{
            //Add MVC
            services.AddMvc()
                .AddViewLocalization();

            //Localization factory
            services.AddSingleton<IStringLocalizerFactory, ApplicationLocalizerFactory>();

            ...
}


public void Configure(IApplicationBuilder app, IHostingEnvironment env, ILoggerFactory loggerFactory, ApplicationDbContext context)
{
            ...

            //Localization
            var supportedCultures = new[]
                {
                    new CultureInfo("en-US"),
                    new CultureInfo("nl-BE")
                };
            var options = new RequestLocalizationOptions {
                DefaultRequestCulture = new RequestCulture("nl-BE"),
                SupportedCultures = supportedCultures,
                SupportedUICultures = supportedCultures
            };
            app.UseRequestLocalization(options);

            ...
}

控制器

public string Index()
{
    return CultureInfo.CurrentCulture.Name;
}

这段代码始终返回 en-US

有人可以帮我解决这个问题吗？

在没有结果的情况下搜索解决方案数小时之后，我进行了大量调试并意识到中间件服务是按配置（IApplicationBuilder应用程序...中声明的顺序执行的。 ）即可。因此，在执行控制器操作之后，调用了本地化中间件。

当我在开始时移动 app.UseRequestLocalization（options）调用时，我在控制器操作中得到了正确的本地化Thread / CultureInfo。

    public void Configure(IApplicationBuilder app, IHostingEnvironment env, ILoggerFactory loggerFactory,
        IApplicationLifetime appLifetime)
    {
        loggerFactory.AddConsole(Configuration.GetSection("Logging"));
        loggerFactory.AddDebug();

        // THIS HAS TO BE A VERY FIRST MIDDLEWARE REGISTRATION
        SetUpLocalization(app);

        app.UseCors("AllowAllOrigins");

        app.UseMvc();

        appLifetime.ApplicationStopped.Register(() => ApplicationContainer.Dispose());
    }

    private static void SetUpLocalization(IApplicationBuilder app)
    {
        var supportedCultures = new[]
        {
            new CultureInfo("en-US"),
            new CultureInfo("pl-PL"),
            new CultureInfo("pl")
        };

        var options = new RequestLocalizationOptions
        {
            DefaultRequestCulture = new RequestCulture("en-US", "en-US"),
            SupportedCultures = supportedCultures,
            SupportedUICultures = supportedCultures
        };
        // Configure the Localization middleware
        app.UseRequestLocalization(options);
    }
