先演示简单的cookie读写操作,下次加入des加密解密,敬请期待!
1HttpCookie cookie = new HttpCookie("AutoLogin");
2 cookie.Values.Add("name", user.UserName);
3 cookie.Values.Add("pass", user.Password);
4 cookie.Expires = DateTime.Now.AddDays(1);
5 Response.AppendCookie(cookie);
1HttpCookie cookies = Request.Cookies["AutoLogin"];
2 if (!IsPostBack)
3 {
4 if (cookies != null)
5 {
6 string name = cookies.Values["name"];
7 string pass = cookies.Values["pass"];
8 if (name != null && !name.Equals("") && pass != null && !pass.Equals(""))
9 {
10 UserManager userManager = new UserManager();
11 if (userManager.Login(name, pass, out user))
12 {
13 limits = userManager.GetLimitsById(user.ID);
14 Session["limits"] = limits;
15 Session["CurrentUser"] = user;
16 Response.Redirect("~/Display/Car/CarList.aspx");
17 }
18 }
19 }
20 }
清空cookies
Response.Cookies["AutoLogin"].Expires = DateTime.Now.AddDays(-1);
