c# - 如何在 ASP.Net Core 1.1 中响应.Cookies.Append()？

Question

我正在尝试将全局化添加到 Intranet 应用程序，使用 cookie 允许用户选择文化偏好。中间件已设置并正在运行，但我在根据 UI 选择附加到 cookie 时遇到了问题。

该方法直接来自 Asp.Net Core 文档，如下所示:

public void ConfigureServices(IServiceCollection services)
{
    services.Configure<RequestLocalizationOptions>(
        options =>
        {
            var supportedCultures = new List<CultureInfo>
            {
            new CultureInfo("en-US"),
            new CultureInfo("en-GB"),
            new CultureInfo("fr-FR"),
            new CultureInfo("es-ES")
            };

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

    services.AddLocalization();
    services.AddMvc(config =>
    {
        var policy = new AuthorizationPolicyBuilder()
                         .RequireAuthenticatedUser()
                         .Build();
        config.Filters.Add(new AuthorizeFilter(policy));
    })
    .AddViewLocalization();

    services.AddSession(options => {
        options.CookieName = "Intranet";
    });
}

public void Configure(IApplicationBuilder app, IHostingEnvironment env, ILoggerFactory loggerFactory)
{
    var locOptions = app.ApplicationServices.GetService<IOptions<RequestLocalizationOptions>>();
    app.UseRequestLocalization(locOptions.Value);

    app.UseSession();
    app.UseMvc(routes =>
    {
        routes.MapRoute(
            name: "default",
            template: "{controller=Home}/{action=Index}/{id?}");
    });
}

[HttpPost]
 public IActionResult SetLanguage(string culture, string returnUrl)
  {
    Response.Cookies.Append(
      CookieRequestCultureProvider.DefaultCookieName,
      CookieRequestCultureProvider.MakeCookieValue(new RequestCulture(culture)),
        new CookieOptions { Expires = DateTimeOffset.UtcNow.AddYears(1) 
   });

   return LocalRedirect(returnUrl);
 }

问题是:

1. 响应不存在
2. 本地重定向不存在

我试过:

1. HttpResponse、HttpRequest
2. 本地重定向结果

从您获得该示例的文档中，您可以看到代码来自 GitHub有很多示例项目。此特定示例来自 Localization.StarterWeb .

你的两个“缺失”方法实际上是 ControllerBase 的一部分(这是 Controller 继承的。所以如果你把这个 Action 方法放到 Controller 中，它就会起作用.

public class HomeController : Controller
{
    [HttpPost]
    public IActionResult SetLanguage(string culture, string returnUrl)
    {
        Response.Cookies.Append(
            CookieRequestCultureProvider.DefaultCookieName,
            CookieRequestCultureProvider.MakeCookieValue(new RequestCulture(culture)),
            new CookieOptions { Expires = DateTimeOffset.UtcNow.AddYears(1) }
        );

        return LocalRedirect(returnUrl);
    }
}
