IUserSession for asp.net mvc application...

gistfile1.txt

My service defintion held inside my services layer - no access to web app

    public interface IUserSession
    {
        void LogOut();
        string GetUsername();
        LoggedonuserDTO GetCurrentUser();
    }


My implementation of this method that IS held inside my web app, is where i want my Kernal to hold this implementation so I can get access to it later on in any service methods or controllers.

public class UserSession : IUserSession
    {
        private readonly IAuthorizationService _authenticationService;
        public UserSession(IAuthorizationService authenticationService)
        {
            _authenticationService = authenticationService;
        }

        private string Username
        {
            get
            {
                if (HttpContext.Current.User != null)
                    return HttpContext.Current.User.Identity.Name;
                else
                    throw new NoAccessException();
            }
        }

        public LoggedonuserDTO GetCurrentUser()
        {
            var identity = HttpContext.Current.User.Identity;
            if (!identity.IsAuthenticated)
                return null;
            var user = _authenticationService.GetLoggedOnUser(Username);
            if (user == null)
                throw new NoAccessException();
            return user;
        }

        public void LogOut()
        {
            HttpContext.Current.User = null;
            FormsAuthentication.SignOut();
        }

        public string GetUsername()
        {
            return Username;
        }
    }

Binding is done in Global.asax

// using NInject to override application started
        protected override void OnApplicationStarted()
        {
            AreaRegistration.RegisterAllAreas();
            // hand over control to NInject to register all controllers
            RegisterRoutes(RouteTable.Routes);
            Container.Get<ILoggingService>().Info("Application started");
            Container.Bind<IUserSession>().To<UserSession>().InRequestScope(); //here is the binding...
        }


Usage scenario:

Note: I want to access IUserSession maybe in any other service call e.g. IEmailService may have IUserSession passed into the ctor e.g.

public EmailService : IEmailService
{
 private readonly IUserSession _session;
 public EmailService(IUserSession _session)
 {
  this._session = _session;
 }

 public void SendMail()
 {
   console.writeline(_session.GetUsername());// this should work...

 }
}
