string username = this.txtUserName.Text;//用户名
string password = this.txtPassword.Text;//密码
if (UserManager.LoginValidate(username, password) && this.ckState.Checked == true)//判断登录名和密码是否正确和是否选择了记住用户名和密码的复选框
{
//判断客户端浏览器是否存在该Cookie 存在就先清除
if (Request.Cookies["username"] != null && Request.Cookies["password"] != null)
{
Response.Cookies["username"].Expires = System.DateTime.Now.AddSeconds(-1);//Expires过期时间
Response.Cookies["password"].Expires = System.DateTime.Now.AddSeconds(-1);
}
else
{
//向客户端浏览器加入Cookie （用户名和密码最好是使用MD5加密）
HttpCookie hcUserName1 = new HttpCookie("username");
hcUserName1.Expires = System.DateTime.Now.AddDays(7);
hcUserName1.Value = username;
HttpCookie hcPassword1 = new HttpCookie("password");
hcPassword1.Expires = System.DateTime.Now.AddDays(7);
hcPassword1.Value = password;
Response.Cookies.Add(hcUserName1);
Response.Cookies.Add(hcPassword1);
}
}

Copy code

------------------------ go to the page after logging in (it is best to write the master page with the motherboard page)------------

if (Request.Cookies["username"] != null && Request.Cookies["password"] != null)
{
//用户曾登录
username = Request.Cookies["username"].Value.ToString(); //读取Cookie
password = Request.Cookies["password"].Value.ToString();//判断Cookie读取出来的用户名和密码是否能正确登录
if (UserManager.LoginValidate(username, password))
{
//登录后的代码
} }

Copy code

------------------------------- opt-out of cookies (plus an opt-out button)-------------------------------

Exit
