在MVC与使用习惯成员资格和角色提供者实施的IPrincipal和IIdentity的 [英] Implementing IPrincipal and IIdentity in MVC with use of custom membership and role provider

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; } 
} 
  

AccountModel：

 公共类FormsAuthenticationService：IFormsAuthenticationService 
 {
公共无效签到（用户名字符串，布尔createPersistentCookie）
 {
如果（String.IsNullOrEmpty（用户名））抛出新的ArgumentException（username的）明镜DARF范沃特NULL nicht奥德盛媚眼。 
 //抓取用户信息插入
 KIMembershipUser =的MembershipUser（KIMembershipUser）Membership.GetUser（用户名）; 
 VAR customInfo =的String.Format（{0} | {1}，membershipUser.Vorname，membershipUser.Nachname）; 
 //创建并加密门票
变种票=新的FormsAuthenticationTicket（
 2，//版本号
用户名，用户名// 
 DateTime.Now，//发行日期
 DateTime.Now.AddMinutes（30），//有效期
 createPersistentCookie，//是否持续
 customInfo //用户数据
）？; 
 VAR encTicket = FormsAuthentication.Encrypt（票）; 
 //存放票到cookie 
变种的cookie = FormsAuthentication.GetAuthCookie（FormsAuthentication.FormsCookieName，createPersistentCookie）; 
 cookie.Value = encTicket; 
 //追加cookie来响应
 HttpContext.Current.Response.Cookies.Add（饼干）; 
 
 //FormsAuthentication.SetAuthCookie(userName，createPersistentCookie）; 
} 
 
公共无效SignOut（）
 {
 FormsAuthentication.SignOut（）; 
} 
} 
  

Global.asax的：

 保护无效Application_PostAuthenticateRequest（）{
 //收集当前的安全信息
 VAR本金= HttpContext.Current.User为RolePrincipal; 
如果（本金== NULL）
的回报; 
变种标识= principal.Identity为FormsIdentity; 
如果（身份== NULL）
的回报; 
变种角色= principal.GetRoles（）;在身份验证票证
 VAR customInfo = identity.Ticket.UserData 
 //提取用户数据; 
 VAR令牌= customInfo.Split（'|'）; 
 //建立一个更丰富的主体对象
变种CustomPrincipal =新CustomPrincipal（身份，角色）{
 Vorname =令牌[0]，
 Nachname =令牌[1] 
}; 
 //将在HttpContext的$新的主体b $ B HttpContext.Current.User = CustomPrincipal; 
} 
  

解决方案

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;
    }

解决方案

Use (CustomPrincipal)Context.User).Nachname instead of (CustomPrincipal)Context.User.Identity).Nachname
