Transfer data to ApplicationController - asp.net

Question

I'm trying to do a login module with view master page. First user access to a home page with a login form, when user click login, page should redirect to a UserLoginController first and then redirect to another PanelController which holds all pages with same master page. I want to show different menus by different user's permission. As I refer a article http://www.asp.net/mvc/tutorials/passing-data-to-view-master-pages-cs I create a abstract class ApplicationController, the PanelController inherit it. In the constructor, I want to get the login user's information to identify user's permission, but it seems Request and Session is not available. Pls see code.
First the login Javascript
<script type="text/javascript" language="javascript">
$(document).ready(function () {
$(btnLogin).click(function () {
var sso = $(txtSSO).val();
var pwd = $(txtPwd).val();
if (sso == "")
{ alert("Please input your SSO number"); }
else if (pwd == "")
{ alert("Please input your password"); }
else {
jQuery.ajax(
{ url: '<%:Url.Action("UserLogin", "UserLogin")%>',
data: { sso: sso, pwd: pwd },
success: function (data) {
window.location = '<%: Url.Action("Demo","Panel") %>';
}
}
);
}
});
});
</script>
The UserLoginController
public ActionResult UserLogin()
{
string sso = "";
string pwd = "";
try
{
if (Request.IsAjaxRequest())
{
sso = Request.Params["sso"].ToString();
pwd = Request.Params["pwd"].ToString();
}
Regex reg = new Regex("^[0-9]{9}$");
if (!reg.Match(sso).Success || pwd == "")
{
ViewData["errorMsg"] = "Either your UserID or your Password is incorrect";
return View("Index");
}
SystemAdminEntities entity = new SystemAdminEntities();
var result = entity.ValidateUserLogin(sso, pwd).FirstOrDefault();
if (result == 1)//User is found
{
int isso = Convert.ToInt32(sso);
var dbEmp = (from e in entity.sys_employee
where e.sso == isso
select e);
SysEmployee emp = dbEmp.FirstOrDefault<SysEmployee>();
LogonUserModel currentUser = LogonUserModel.GetUser();
currentUser.CopyUserInfo(emp);
//FormsAuthenticationTicket ticket=new
FormsAuthentication.SetAuthCookie(currentUser.SSO.ToString(), true);
Session.Add("emp", currentUser);
this.Session.Add("sso", currentUser.SSO);
this.Session.Add("empid", currentUser.EmpID);
this.Session.Add("ename", currentUser.EName);
return RedirectToAction("Demo", "Panel");//重定向到 Demo
}
else if (result == 0)//User is not found
{
ViewData["errorMsg"] = "User isn't found";
return View("Index");
}
else if (result == 2)//Password not correct
{
ViewData["errorMsg"] = "Password Error";
return View("Index");
}
return View("Index");
}
catch { return View("Index"); }
}
The ApplicationController
public abstract class ApplicationController : Controller
{
private SystemAdminEntities _entities = new SystemAdminEntities();
public ApplicationController()
{
//根据人员判断权限
int sso = 0;//= Request.Form["sso"].ToString();
try
{
sso = int.Parse(Session["sso"].ToString());
var e = (from emp in _entities.sys_employee//得到对应的用户
where emp.sso == sso
select emp
);
SysEmployee loginUser = e.FirstOrDefault<SysEmployee>();
ViewData["modules"] = loginUser.SysHasPerm;
}
catch
{
ViewData["modules"] = null;
}
}
The PanelController
public class PanelController : ApplicationController
{
//
// GET: /Panel/
public ActionResult Index()
{
return View();
}
public ActionResult Demo()
{
return View();
}
}

ViewData is used in MVC to pass data from Controllor to View
and Tempdata is used to pass data from one Controllor to other
Refer Passing State Between Action Methods
