Question

为何取不到cookie的值

protected void btnAdd_Click(object sender, EventArgs e)
{
HttpCookie cookie1 = new HttpCookie("name");
Response.Cookies["name"].Value = txtAdd.Text;
Response.Cookies["name"].Expires = DateTime.Now.AddDays(1);
Response.Cookies.Add(cookie1);
}

protected void btnShow_Click(object sender, EventArgs e)
{
HttpCookie cookie2 = Request.Cookies["name"];
lblShow.Text = cookie2.Value;
}
}

Answer 1

1. 检查php设置cookie的域名和js读取的域名是同一个；

2. 确定php setcookie成功了与否；
   

3. js读取cookie函数靠谱么；

4. 如果以上都是  用浏览器看一下当前页的cookie是否有 可以用 google chrome谷歌浏览器F12 或者 firefox火狐浏览器firebug 查看

Answer 2

HttpCookie cookie1 = new HttpCookie("name");
Response.Cookies["name"].Value = txtAdd.Text;
Response.Cookies["name"].Expires = DateTime.Now.AddDays(1);
Response.Cookies.Add(cookie1);

改为
cookie1.Value = txtAdd.Text;
cookie1.Expires = DateTime.Now.AddDays(1);
Response.Cookies.Add(cookie1);
