使用Cookie进行登录验证

nnd用框架做后台，session总是丢失。无奈，使用cookie把。

 

HttpCookie myCookie = new HttpCookie("myCookie");
myCookie.Values.Add("AdminName", this.txtName.Text.Trim().ToString());
myCookie.Values.Add("Pwd", this.txtPwd.Text.Trim().ToString());
myCookie.Expires = DateTime.Now.AddHours(3);           //cookie保存时间   

Response.AppendCookie(myCookie);

 

//验证

if (Request.Cookies["myCookie"] == null)
{
      Response.Redirect("~/Admin/Login.aspx");
}

 

 

//取值

this.lblName.Text = Request.Cookies["myCookie"].Values["AdminName"].ToString();

 

 

//安全退出or注销

Response.Cookies["myCookie"].Expires = DateTime.Now.AddDays(-1);                      //使cookie过期
        Page.ClientScript.RegisterStartupScript(this.GetType(), "", "<script>parent.location.href="Login.aspx";</script>");

 

 

备用(解决中文乱码)：

编码： myCookie.Values.Add("AdminName", HttpUtility.UrlEncode(this.txtName.Text.Trim().ToString(), System.Text.Encoding.GetEncoding("gb2312")));

解码：this.lblName.Text = HttpUtility.UrlDecode(Request.Cookies["myCookie"].Values["AdminName"].ToString(), System.Text.Encoding.GetEncoding("gb2312"));
