库中的.NET Core MVC本地化设置文化

Question

我很沮丧，我尝试使用标准的Microsoft本地化机制。 但是，从现在开始的两天以来，我努力达到可以在外部库中设置/更改当前文化的目的。

但是系统会忽略它。 ;（

这是我的StartUp.cs

// This method gets called by the runtime. Use this method to add services to the container.
    public void ConfigureServices(IServiceCollection services)
    {                       
        services.AddSingleton<IHttpContextAccessor, HttpContextAccessor>(); //TODO: With .net Core 2.1 services.AddHttpContextAccessor();

        services.AddMvc()
            .AddViewLocalization(LanguageViewLocationExpanderFormat.Suffix)
            .AddDataAnnotationsLocalization();

        services.AddPortableObjectLocalization(options => options.ResourcesPath = "Localization");              
        services.Replace(ServiceDescriptor.Singleton<ILocalizationFileLocationProvider, LocalizationLoader>());
    }


    // This method gets called by the runtime. Use this method to configure the HTTP request pipeline.
    public void Configure(IApplicationBuilder app, IHostingEnvironment env)
    {   
        if (env.IsDevelopment())
        {
            app.UseBrowserLink();
            app.UseDeveloperExceptionPage();
        }
        else
        {
            app.UseExceptionHandler("/Home/Error");
        }

        var supportedCultures = new[]
        {
            new CultureInfo("de-DE"),
            new CultureInfo("en-GB"),
        };

        app.UseRequestLocalization(new RequestLocalizationOptions
        {
            DefaultRequestCulture = new RequestCulture("de-DE"),            
            // Formatting numbers, dates, etc.
            SupportedCultures = supportedCultures,
            // UI strings that we have localized.
            SupportedUICultures = supportedCultures
        });         

        app.UseStaticFiles();

        app.UseMvc(routes =>
        {
            routes.Routes.Add((IRouter) dynamicRouter);                     
        });
    }

这是我的控制器操作，它在库中（可能不重要，而不是直接在MVC应用程序中）。 该操作将被调用，不会引发任何异常，但是在IViewLocalizer中，区域性始终始终是“ de-DE”。

public async Task<IActionResult> Get(string contentItemId)
    {
        // Just a try from the Internet
        _httpContextAccessor.HttpContext.Response.Cookies.Append(
            CookieRequestCultureProvider.DefaultCookieName,
            CookieRequestCultureProvider.MakeCookieValue(new RequestCulture(new CultureInfo("en-GB"))),
            new CookieOptions { Expires = DateTimeOffset.UtcNow.AddYears(1) }
        );

        // I thought one of these are right
        CultureInfo.CurrentCulture = new CultureInfo("en-GB");
            CultureInfo.CurrentUICulture = new CultureInfo("en-GB");
            CultureInfo.DefaultThreadCurrentCulture = new CultureInfo("en-GB");
            CultureInfo.DefaultThreadCurrentUICulture = new CultureInfo("en-GB");

        return View();
    }

总是在我再次执行操作（刷新F5浏览器）时，CultureInfo再次为“ de-DE”（默认）。 ;（

尝试像这样在服务中添加您的配置：

 services.Configure<RequestLocalizationOptions>(options =>
            {
                var supportedCultures = new[]
                {
                        new CultureInfo("en-US"),
                        new CultureInfo("fr-FR")
                };

                options.DefaultRequestCulture = new RequestCulture(culture: "en-US", uiCulture: "en-US");
                options.SupportedCultures = supportedCultures;
                options.SupportedUICultures = supportedCultures;
});

然后让UseRequestLocalization空：

 app.UseRequestLocalization();
