读取Cookies的Domain问题

[九章落地]

FormsAuthentication.SetAuthCookie(txtname.Value, false);
HttpCookie lcookie = Context.Response.Cookies[FormsAuthentication.FormsCookieName];
lcookie.Domain = ".wisdom.cn";
lcookie.Expires = DateTime.Now.AddMinutes(30);
Response.Redirect(FormsAuthentication.GetRedirectUrl(txtname.Value,false));
==============================================================
以上是写入Cookies的代码

可是,当我想读出COOKIES所在域时
Request.Cookies[FormsAuthentication.FormsCookieName].Domain.ToString();
它就说,未将对像引用到实例
直接读Request.Cookies[FormsAuthentication.FormsCookieName].Domain
是空的,快疯鸟

试试
Response.Cookies[FormsAuthentication.FormsCookieName].Domain.ToString();

用cookie的话，Request和Response要分清楚。

还是不行

HttpCookie hc = new HttpCookie("test");
hc.Domain = ".wisdom.cn";
Response.Cookies.Add(hc);

Response.Write(Request.Cookies["test"].Domain.ToString());

这样写就一点问题都没有

写cookie的时候要用Request，不能用Response

取cookie的时候，要看是在　Request　还是　Response　里。

FormsAuthentication.SetAuthCookie(txtname.Value, false);
HttpCookie lcookie = Context.Request.Cookies[FormsAuthentication.FormsCookieName];
lcookie.Domain = ".wisdom.cn";
lcookie.Expires = DateTime.Now.AddMinutes(30);
Response.Redirect(FormsAuthentication.GetRedirectUrl(txtname.Value,false));
==================================================================================
Request.Cookies[FormsAuthentication.FormsCookieName].Domain.ToString();
Response.Cookies[FormsAuthentication.FormsCookieName].Domain.ToString();
都是未将对象引用设置到对象的实例。

难道是Forms验证就不能读取Domain??

[BearRui]

首先看看你是Response.Cookies[FormsAuthentication.FormsCookieName]为null

还是Response.Cookies[FormsAuthentication.FormsCookieName].Domain为null

[greatqn]

应该不是domain取不到，而是这个cookie本来就取不到。
Request.Cookies[FormsAuthentication.FormsCookieName]
和　Response.Cookies[FormsAuthentication.FormsCookieName]　都是空吧。

Domain的话，需要和网站域名对应，否则是取不到cookie值。还不如为空或"."

取domain好象没什么意义啊？

[牛人]

支持一下.

我能想到的都说了.

[九章落地]

HttpCookie lcookie = Context.Request.Cookies[FormsAuthentication.FormsCookieName];
Response.Write(lcookie.Value.ToString());
不为空
这个就能读,读出一串加密串

[BearRui]

应该是楼主设置domain的地方有问题，楼主试试这样设置：

protected void Application_EndRequest(Object sender, EventArgs e)
{
HttpCookieCollection cookies = HttpContext.Current.Response.Cookies;
for (int i = 0; i < cookies.Count; i++)
{
cookies[i].Domain = ".wisdom.cn";
}
}
