ASP.NET MVC 5-未创建Cookie

Question

我的控制器操作调用了处理cookie的私有方法。 问题在于根本没有创建cookie。 我在SO上阅读了多篇文章，但没有找到答案，因为我认为此代码中的Cookie处理是正确的。

关于cookie，我需要检查任何web.config设置吗？ 我还尝试了不同的浏览器。

我调试了代码，可以看到代码中实际上设置了cookie，但是一旦加载页面并查看cookie，cookie就不存在了。

  private ABHomeModel HandleWhiteBoxCookie(ABHomeModel model)
        {
            var whiteBox = _whiteBoxService.GetActiveWhiteBox();

            if (model.WhiteBox != null)
            {
                const string cookieName = "whiteBox";

                var whiteBoxCookie = HttpContext.Request.Cookies.Get(cookieName);

                if (whiteBoxCookie != null)
                {
                    var displayedTimes = Convert.ToInt32(whiteBoxCookie.Value);
                    if (displayedTimes < 2)
                    {
                        displayedTimes++;

                        var cookie = new HttpCookie(cookieName, displayedTimes.ToString())
                        {
                            Expires = new DateTime().AddMonths(1),
                            Secure = false
                        };

                        HttpContext.Response.Cookies.Set(cookie);
                        ViewBag.IsWhiteBoxActive = true;
                    }
                    else
                    {
                        ViewBag.IsWhiteBoxActive = false;
                    }
                }
                else
                {
                    var cookie = new HttpCookie(cookieName, "1")
                    {
                        HttpOnly = true,
                        Domain = Request.Url.Host,
                        Expires = DateTime.Now.AddMonths(1),
                        Secure = false
                    };

                    HttpContext.Response.Cookies.Add(cookie);
                    ViewBag.IsWhiteBoxActive = true;
                }

                model.WhiteBox = whiteBox;
            }

            return model;
        }

我的同事发现了问题。 与设置域有关。 一旦我们删除这一行：

Domain = Request.Url.Host,

Cookies开始工作，现在正在创建。

该方法的完整更新代码：

private ABHomeModel HandleWhiteBoxCookie(ABHomeModel model)
        {
            var whiteBox = _whiteBoxService.GetActiveWhiteBox();

            if (whiteBox != null)
            {
                const string cookieName = "whiteBox";

                var whiteBoxCookie = HttpContext.Request.Cookies.Get(cookieName);

                if (whiteBoxCookie != null)
                {
                    var displayedTimes = Convert.ToInt32(whiteBoxCookie.Value);
                    if (displayedTimes < 2)
                    {
                        displayedTimes++;

                        var cookie = new HttpCookie(cookieName, displayedTimes.ToString())
                        {
                            HttpOnly = true,
                            Secure = false
                        };

                        HttpContext.Response.Cookies.Set(cookie);
                        ViewBag.IsWhiteBoxActive = true;
                    }
                    else
                    {
                        ViewBag.IsWhiteBoxActive = false;
                    }
                }
                else
                {
                    var cookie = new HttpCookie(cookieName, "1")
                    {
                        HttpOnly = true,
                        Expires = DateTime.Now.AddMonths(1),
                        Secure = false
                    };

                    HttpContext.Response.Cookies.Add(cookie);
                    ViewBag.IsWhiteBoxActive = true;
                }

                model.WhiteBox = whiteBox;
            }

            return model;
        }
