asp.net Forms登录核心方法

登录核心方法:

 private void Signin(string curUserId)
{

System.Web.Security.FormsAuthenticationTicket tk = new FormsAuthenticationTicket(1,
                    curUserId,
                    DateTime.Now,
                    DateTime.Now.AddDays(1),
                    true,
                    "",
                    System.Web.Security.FormsAuthentication.FormsCookiePath
                    );

            string key = System.Web.Security.FormsAuthentication.Encrypt(tk); //得到加密后的身份验证票字串 

            HttpCookie ck = new HttpCookie(System.Web.Security.FormsAuthentication.FormsCookieName, key);
            //ck.Domain = System.Web.Security.FormsAuthentication.CookieDomain;  // 这句话在部署网站后有用，此为关系到同一个域名下面的多个站点是否能共享Cookie
            HttpContext.Current.Response.Cookies.Add(ck);
            HttpContext.Current.Response.Cookies["MenuStyle"].Expires = DateTime.Now.AddDays(1);
            HttpContext.Current.Response.Cookies["PageSize"].Expires = DateTime.Now.AddDays(1);
            HttpContext.Current.Response.Cookies["TableSink"].Expires = DateTime.Now.AddDays(1);
}
