以上是我login.aspx的代码，放在虚拟空间中后，取不到COOKIE的值。

无法获取COOKIE的值

16 个解决方案

#1

浏览器是不是禁止了cookies

#2

浏览器没有禁止COOKIE。我在星辉互联的虚拟空间上就是这种情况，星辉互联的技术说是瞬间虚拟内存占用超标，用云主机不限制使用内存就没问题了。

我在万网试用云主机确实没问题。在虚拟空间中就不行，我也不知道再怎样优化程序。

#3

自己顶一下，大侠们有知道的吗？

#4

COOKIE存储实在浏览器，应该和服务器的关系不大；

不然你自己找一个网页抓包的工具，看看你存的值是啥……

#5

wangnaisheng：那怎么使用云主机就没问题了呢？晕

#6

使用HttpWatch Studio网页抓包，也有COOKIE的传递，但是就是取不到值。

#7

这个怕是没多少人知道怎么解决。

#8

smthgdin：为什么呢？？？能把你的想法告诉我吗？

#9

这是幸会互联的技术发给我的时间跟踪结果。

有大侠知道怎么回事吗？

标准是多少？

#11

sp1234:你好！

虚拟内存标准是500兆。

我觉着就这两个页面能用500兆？真是不可思议。

还没见过这样的问题，楼下接上

实现Cookie值的记忆功能
//将用户名密码值存入Cookie
protected void Button1_Click(object sender, EventArgs e)
    {
        if (txtname.Text.Trim().Equals("mr") && txtpwd.Text.Trim().Equals("mrsoft"))
        {
            Session["username"] = txtname.Text.Trim();
            if (ckbauto.Checked)
            {
                if (Request.Cookies["username"] == null)
                {
                    Response.Cookies["username"].Expires = DateTime.Now.AddDays(30);
                    Response.Cookies["userpwd"].Expires = DateTime.Now.AddDays(30);
                    Response.Cookies["username"].Value = txtname.Text.Trim();
                    Response.Cookies["userpwd"].Value = txtpwd.Text.Trim();
                }
            }
            Response.Redirect("admin.aspx");
        }
        else
        {
            ClientScript.RegisterStartupScript(this.GetType(),"","alert('用户名或密码错误！');",true);
        }
    }//CodeGo.net/
//把上次输入记忆的密码显示在文本框
protected void txtname_TextChanged(object sender, EventArgs e)
    {
        if (Request.Cookies["username"] != null)
        {
            if (Request.Cookies["username"].Value.Equals(txtname.Text.Trim()))
            {
                txtpwd.Attributes["value"] = Request.Cookies["userpwd"].Value;
            }
        }
    }

asp.net 怎么会用import 应该是using吧你应该去java 无法获取COOKIE的值

#15

zhao_WX:你好！

我用的VB语言，正准备改到C#
