使用自定义成员资格和角色提供程序在 MVC 中实现 IPrincipal 和 IIdentity

问题描述

我一直坚持自定义 iprincpal 和 iidentity 对象的实现.我现在花了一天时间来搜索如何实现这些权利并用更多信息对其进行扩展.

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.

我想使用自定义变量(如全名或其他内容)扩展信息 @Context.User.Identity.Name.

I want to extend the Information @Context.User.Identity.Name with custom variables like full name or something else.

EDIT:现在我得到了以下代码，但是如果我尝试阅读 @((CustomPrincipal)Context.User.Identity).Nachname 我收到一个错误System.Web.Security.FormsIdentity 无法转换为 CustomPrincipal.

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.

有什么想法吗?

public class CustomPrincipal : GenericPrincipal
{
    public CustomPrincipal(IIdentity identity, String[] roles) : base(identity, roles){

    }
    public String Vorname { get; set; }
    public String Nachname { get; set; }
}

账户模型:

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:

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;
    }

推荐答案

使用 (CustomPrincipal)Context.User).Nachname 而不是 (CustomPrincipal)Context.User.Identity).Nachname
