请求这个地址的时候设置了一个cookie
(地址1）http://localhost:2234/handler/account/login.ashx
返回成功后，跳转地址2的时候cookie获取不到（null）
（地址2） http://localhost:2234/index.aspx
这是这么回事？
cookie设置和获取我贴出来
public class CookieHelper { /// <summary> /// 清除指定Cookie /// </summary> /// <param name="cookiename">cookiename</param> public static void ClearCookie(string cookiename) { HttpCookie cookie = HttpContext.Current.Request.Cookies[cookiename]; if (cookie != null) { cookie.Expires = DateTime.Now.AddYears(-3); HttpContext.Current.Response.Cookies.Add(cookie); } } /// <summary> /// 获取指定Cookie值 /// </summary> /// <param name="cookiename">cookiename</param> /// <returns></returns> public static string GetCookieValue(string cookiename) { HttpCookie cookie = HttpContext.Current.Request.Cookies[cookiename]; string str = string.Empty; if (cookie != null) { str = cookie.Value; } return str; } /// <summary> /// 添加一个Cookie（24小时过期） /// </summary> /// <param name="cookiename"></param> /// <param name="cookievalue"></param> public static void SetCookie(string cookiename, string cookievalue) { SetCookie(cookiename, cookievalue, DateTime.Now.AddDays(1.0)); } /// <summary> /// 添加一个Cookie /// </summary> /// <param name="cookiename">cookie名</param> /// <param name="cookievalue">cookie值</param> /// <param name="expires">过期时间 DateTime</param> public static void SetCookie(string cookiename, string cookievalue, DateTime expires) { HttpCookie cookie = new HttpCookie(cookiename) { Value = cookievalue, Expires = expires }; HttpContext.Current.Response.Cookies.Add(cookie); } }

我这里用你的方式设置cookie，是可以正常读取的，建议检查一下是否出现什么低级错误，比如 cookieName 不相同
