標準的asp.net 和 MVC都適用
驗證密碼後所要作的事，把資料寫入 cookie中
FormsAuthenticationTicket ticket = new FormsAuthenticationTicket(
1, // Ticket version
Username.Value, // Username associated with ticket
DateTime.Now, // Date/time issued
DateTime.Now.AddMinutes(30), // Date/time to expire
true, // "true" for a persistent user cookie
reader.GetString(0), // User-data, in this case the roles
FormsAuthentication.FormsCookiePath);// Path cookie valid for
// Encrypt the cookie using the machine key for secure transport
string hash = FormsAuthentication.Encrypt(ticket);
HttpCookie cookie = new HttpCookie(FormsAuthentication.FormsCookieName, hash); // Set the cookie's expiration time to the tickets expiration time
if (ticket.IsPersistent) cookie.Expires = ticket.Expiration;
// Add the cookie to the list for outgoing response
Response.Cookies.Add(cookie);最重要的是要在 Global.asax 加上這些程式碼
protected void Application_AuthenticateRequest(Object sender,
EventArgs e)
{
if (HttpContext.Current.User != null)
{
if (HttpContext.Current.User.Identity.IsAuthenticated)
{
if (HttpContext.Current.User.Identity is FormsIdentity)
{
FormsIdentity id =
(FormsIdentity)HttpContext.Current.User.Identity;
FormsAuthenticationTicket ticket = id.Ticket;
// Get our roles from user Data
string userData = ticket.UserData;
string[] roles = userData.Split(',');
HttpContext.Current.User = new GenericPrincipal(id, roles);
}
}
}
}
