问题描述
我坚持使用自定义iprincpal和的IIdentity对象的实现。我花了一天,现在搜索如何实现这些权利,并与更多的信息扩展它。
我要扩展信息 @ Context.User 。.Identity.Name
像全名或别的什么自定义变量
修改:现在,我得到了以下代码,但如果我尝试读 @((CustomPrincipal)Context.User.Identity).Nachname
我得到一个错误的System.Web。 Security.FormsIdentity
不能被强制转换为 CustomPrincipal
。
任何想法
公共类CustomPrincipal:?的GenericPrincipal
{
公共CustomPrincipal(的IIdentity身份的String []角色):基地(身份,角色){
}
公共字符串Vorname {搞定;组; }
公共字符串Nachname {搞定;组; }
}

使用(CustomPrincipal)Context.User).Nachname
而不是(CustomPrincipal)Context.User.Identity).Nachname
I'm stuck with the implementation of a custom iprincpal and iidentity object. I spend a day now for searching how to implement these right and extend it with more informations.
I want to extend the Information @Context.User.Identity.Name
with custom variables like full name or something else.
EDIT: Now i got the following code but if i try to read @((CustomPrincipal)Context.User.Identity).Nachname
I'm getting a error that System.Web.Security.FormsIdentity
could not be casted to CustomPrincipal
.
Any ideas?
public class CustomPrincipal : GenericPrincipal
{
public CustomPrincipal(IIdentity identity, String[] roles) : base(identity, roles){
}
public String Vorname { get; set; }
public String Nachname { get; set; }
}
AccountModel:
public class FormsAuthenticationService : IFormsAuthenticationService
{
public void SignIn(string userName, bool createPersistentCookie)
{
if (String.IsNullOrEmpty(userName)) throw new ArgumentException("Der Wert darf nicht NULL oder leer sein.", "userName");
// Grab user information to insert
KIMembershipUser membershipUser = (KIMembershipUser)Membership.GetUser(userName);
var customInfo = String.Format("{0}|{1}", membershipUser.Vorname, membershipUser.Nachname);
// Create and encrypt the ticket
var ticket = new FormsAuthenticationTicket(
2, // Version number
userName, // Username
DateTime.Now, // Issue date
DateTime.Now.AddMinutes(30), // Expiration date
createPersistentCookie, // Is it persistent?
customInfo // User data
);
var encTicket = FormsAuthentication.Encrypt(ticket);
// Store the ticket into a cookie
var cookie = FormsAuthentication.GetAuthCookie(FormsAuthentication.FormsCookieName,createPersistentCookie);
cookie.Value = encTicket;
// Append the cookie to the response
HttpContext.Current.Response.Cookies.Add(cookie);
//FormsAuthentication.SetAuthCookie(userName, createPersistentCookie);
}
public void SignOut()
{
FormsAuthentication.SignOut();
}
}
global.asax:
protected void Application_PostAuthenticateRequest(){
// Collect current security information
var principal = HttpContext.Current.User as RolePrincipal;
if (principal == null)
return;
var identity = principal.Identity as FormsIdentity;
if (identity == null)
return;
var roles = principal.GetRoles();
// Extract user data in the authentication ticket
var customInfo = identity.Ticket.UserData;
var tokens = customInfo.Split('|');
// Build a richer principal object
var CustomPrincipal = new CustomPrincipal(identity, roles){
Vorname = tokens[0],
Nachname = tokens[1]
};
// Store the new principal in the HttpContext
HttpContext.Current.User = CustomPrincipal;
}
Use (CustomPrincipal)Context.User).Nachname
instead of (CustomPrincipal)Context.User.Identity).Nachname
