急！！！ 记住密码

Question

记住密码放在了cookie中，下次登录输入用户名后怎样调出cookie呢？ 调出后赋值密码框，但.net 密码框默认不能加载时赋值，怎么写？ 要源码啊！！！

Answer 1

用js，也能操作cookie的，具体怎么操作请baidu

Answer 2

不是加载密码你想想加载密码有什么用下次登录是在load事件里面自己给判断帐号密码了直接登录 跳转到登录 后的页面和状态 不用与这些 控件赋值有关系

Answer 3

不知道你的意思是不是普通网站那些“记住我”的功能。
如果是那样的话，一般是这样实现的。登陆后把用户账户密码存到cookie。
当SESSION过期以后，比如说第二天用户再登陆，网站检测SESSION，发现他没登陆。
第二步读cookie，如果cookie里有账户密码，就用cookie里面的登陆，这个过程不跳转的话，在用户看来就像是他一直保持着登陆状态一样。

Answer 4

Password.Attributes["value"] = Funs.GetCookie("TUserPass");
        /// <summary>
        /// 读cookie值
        /// </summary>
        /// <param name="strName">名称</param>
        /// <returns>cookie值</returns>
        public static string GetCookie(string strName)
        {
            try
            {
                if (HttpContext.Current.Request.Cookies != null && HttpContext.Current.Request.Cookies[strName] != null)
                {
                    return HttpContext.Current.Request.Cookies[strName].Value.ToString();
                }
                return "";
            }
            catch (Exception)
            {
                return "";              
            }
        }记得一般cookie记密码都要加密，读出来再解密。

Answer 5

你干嘛要赋值到密码输入框呢？你看看CSDN的登陆模式，如果你选择记住密码(保存至cookies)，你再打开登陆页面，程序直接跳转到后台了，不出现登陆框了，除非你选择退出。

Answer 6

Cookies怎么存就怎么取 ，只要key一样就行。密码赋值   text.Attributes["value"] = "123456" 
          text.Attributes.Add("value","123456")

登陆代码,部分protected void Page_Load(object sender, EventArgs e)

一般通常情况下，都是使用cookie来记录用户名和密码。以下是部分代码：protected void Page_Load(object sender, EventArgs e)
        {
            HttpCookie cookies = Request.Cookies["platform"];
            //判断是否有cookie值，有的话就读取出来
            if (cookies != null && cookies.HasKeys)
            {
                tbxUserName.Text = cookies["Name"];
                //tbxPwd.Text= cookies["Pwd"];
                tbxPwd.Attributes.Add("value", cookies["Pwd"]);
                this.chkState.Checked = true;
            }
        }
        protected bool getUser()
        {
            string userName = tbxUserName.Text.Trim();//用户名
            string userPwd = FormsAuthentication.HashPasswordForStoringInConfigFile(tbxPwd.Text.Trim(), "MD5"); //MD5密码
            StringBuilder strWhere=new StringBuilder();
            strWhere.AppendFormat("auserName='{0}' and auserPassword='{1}'", userName, userPwd);
            bl.A_TUser user = new bl.A_TUser();
            DataSet ds = new DataSet();
            ds=user.GetList(strWhere.ToString());
            if (ds.Tables[0].Rows.Count>0)
            {
                if (chkState.Checked)//记录cookie值
                {
                      HttpCookie cookie = new HttpCookie("platform");
                      cookie.Values.Add("Name", tbxUserName.Text.Trim());
                      cookie.Values.Add("Pwd", tbxPwd.Text.Trim());
                      cookie.Expires = System.DateTime.Now.AddDays(7.0);
                      HttpContext.Current.Response.Cookies.Add(cookie);
                }
                //else
                //{
                //    if (Response.Cookies["platform"] != null)
                //        Response.Cookies["platform"].Expires = DateTime.Now;
                //}
                Session["userId"] = ds.Tables[0].Rows[0][0].ToString();
                Session["userName"] = ds.Tables[0].Rows[0][1].ToString();
                return true;
            }
            return false;
        }
        protected void btnLogin_Click(object sender, EventArgs e)
        {
            if (getUser())
            {
                Response.Redirect("Default.aspx");
            }
            else
            {
                MessageBox.Show(this, "用户名和密码不正确");
            }
        }    } 
还有一种就是XML方式记住密码http://bbs.gimoo.net/thread/95621-1.html

Answer 10

用cookie实现，挺简单的吧
var cookiesName = "ldrkgl_2011";
        window.onload = function(){
           if($("hf_IsLoadCookies").value != "false")
           {
               var cval = getCookie(cookiesName);
               if(cval != null)
               {
                  $("txt_UserID").value = cval.split("|")[0];
                  $("txt_PassWord").value = cval.split("|")[1];
                  $("cb_Savestates").checked = true;
               }
           }
        }
//写cookies函数
function setCookie(name,value)//两个参数，一个是cookie的名子，一个是值
{
    var Days = 30; //此 cookie 将被保存 30 天
    var exp  = new Date();    //new Date("December 31, 9998");
    exp.setTime(exp.getTime() + Days*24*60*60*1000);
    document.cookie = name + "="+ escape (value) + ";expires=" + exp.toGMTString();
}function getCookie(name)//取cookies函数        
{
    var arr = document.cookie.match(new RegExp("(^| )"+name+"=([^;]*)(;|$)"));
     if(arr != null) return unescape(arr[2]); return null;
}function delCookie(name)//删除cookie
{
    var exp = new Date();
    exp.setTime(exp.getTime() - 4);
    var cval=getCookie(name);
    if(cval!=null) document.cookie= name + "="+cval+";expires="+exp.toGMTString();
}

Answer 11

登陆页的Load事件中。。去检查有没有XX这个cookies..如果有赋值给用户名和密码框。。密码框的赋值有点不同。密码框的ID.TextMode = TextBoxMode.Password;
密码框的ID.Attributes.Add("value", "这里是你从cookies中读出来的");

Answer 12

密码框赋值
txtpwd.TextMode = TextBoxMode.Password;
txtpwd.Text = "mypwd";
