C＃多值cookie无法正常工作

Question

您好我正在通过以下方式创建Cookie：

HttpCookie cookie = new HttpCookie("CookieNameHere");
cookie.Values["test1"] = "Value1";
cookie.Values["test2"] = "Value2";
cookie.Values["test3"] = "Value3";
//I have also tried cookie.Values.Add("test1", "Value1");

cookie.Expires = DateTime.Now.AddDays(365d);
HttpContext.Current.Response.AppendCookie(cookie); //here I have also tried HttpContext.Current.Response.Cookies.Add(cookie);

但是当我使用以下代码读出cookie时：

HttpCookie cookie = new HttpCookie("CookieNameHere");
cookie = HttpContext.Current.Response.Cookies["CookieNameHere"];

我总是认为cookie.Values是空的

我在这里做错了吗？

Answer 1

通常您会在Response中编写Cookie，然后从后续Requests中读取。

我看到你试图从Response读取它 - 这是在同一个HTTP请求的上下文中，还是只是一个错字？

尝试

HttpCookie cookie = HttpContext.Current.Request.Cookies["CookieNameHere"];

Answer 2

您必须在请求中询问这些Cookie。

HttpCookie cookie = Request.Cookies["CookieName"];
