This is the login function (after I validate user name and password, I load user data into "user" variable and call Login function:
public static void Login(IUser user)
{
HttpResponse Response = HttpContext.Current.Response;
HttpRequest Request = HttpContext.Current.Request;
FormsAuthenticationTicket ticket = new FormsAuthenticationTicket(1,
user.UserId.ToString(), DateTime.Now, DateTime.Now.AddHours(12), false,
UserResolver.Serialize(user));
HttpCookie cookie = new HttpCookie(FormsAuthentication.FormsCookieName,
FormsAuthentication.Encrypt(ticket));
cookie.Path = FormsAuthentication.FormsCookiePath;
Response.Cookies.Add(cookie);
string redirectUrl = user.HomePage;
Response.Redirect(redirectUrl, true);
}
UserResolver is the following class:
public class UserResolver
{
public static IUser Current
{
get
{
IUser user = null;
if (HttpContext.Current.User.Identity.IsAuthenticated)
{
FormsIdentity id = (FormsIdentity)HttpContext.Current.User.Identity;
FormsAuthenticationTicket ticket = id.Ticket;
user = Desrialize(ticket.UserData);
}
return user;
}
}
public static string Serialize(IUser user)
{
StringBuilder data = new StringBuilder();
StringWriter w = new StringWriter(data);
string type = user.GetType().ToString();
//w.Write(type.Length);
w.WriteLine(user.GetType().ToString());
StringBuilder userData = new StringBuilder();
XmlSerializer serializer = new XmlSerializer(user.GetType());
serializer.Serialize(new StringWriter(userData), user);
w.Write(userData.ToString());
w.Close();
return data.ToString();
}
public static IUser Desrialize(string data)
{
StringReader r = new StringReader(data);
string typeStr = r.ReadLine();
Type type=Type.GetType(typeStr);
string userData = r.ReadToEnd();
XmlSerializer serializer = new XmlSerializer(type);
return (IUser)serializer.Deserialize(new StringReader(userData));
}
}
And the global.asax implements the following:
void Application_PostAuthenticateRequest(Object sender, EventArgs e)
{
IPrincipal p = HttpContext.Current.User;
if (p.Identity.IsAuthenticated)
{
IUser user = UserResolver.Current;
Role[] roles = user.GetUserRoles();
HttpContext.Current.User = Thread.CurrentPrincipal =
new GenericPrincipal(p.Identity, Role.ToString(roles));
}
}
First question:
Am I do it right?
Second question - weird thing!
The user variable I pass to Login has 4 members: UserName, Password, Name, Id.
When UserResolver.Current executed, I got the user instance.
I descided to change the user structure - I add an array of Warehouse object.
Since that time, when UserResolver.Current executed (after Login), HttpContext.Current.User.Identity.IsAuthenticated was false and I couldn't get the user data.
When I removed the Warehouse[] from user structure, it starts to be ok again and HttpContext.Current.User.Identity.IsAuthenticated become true after I Login.
What is the reason to this weird behaviour?
