Это то, что мы сделали в BaseAnonymousController
public class BaseAnonymousController : Controller
{
protected override void OnAuthentication(System.Web.Mvc.Filters.AuthenticationContext filterContext)
{
if (filterContext.Controller.GetType().Name == "AccountController" && filterContext.ActionDescriptor.ActionName == "login")
{
Guid result;
if (!string.IsNullOrEmpty(SessionVariables.UserId) && Guid.TryParse(SessionVariables.UserId, out result))
{
//Already a anonymous user, so good to go.
}
else
{
//Seems to be a logged in a user. So, clear the session
Session.Clear();
}
}
//Perform a false authentication for anonymous users (signup, login, activation etc. views/actions) so that SignalR will have a user name to manage its connections
if (!string.IsNullOrEmpty(SessionVariables.UserId))
{
filterContext.HttpContext.User = new CustomPrincipal(new CustomIdentity(SessionVariables.UserId, "Anonymous"));
}
else
{
string userName = Guid.NewGuid().ToString();
filterContext.HttpContext.User = new CustomPrincipal(new CustomIdentity(userName, "Anonymous"));
FormsAuthentication.SetAuthCookie(userName, false);
SessionVariables.UserId = userName;
}
base.OnAuthentication(filterContext);
}
}
и использовал этот класс как базовый для всех анонимных контроллеров.
public class AccountController : BaseAnonymousController
{
[AllowAnonymous]
public ActionResult Signup()
{
//Your code
}
[AllowAnonymous]
public ActionResult Login()
{
//Your code
}
[AllowAnonymous]
public ActionResult ForgotPassword()
{
//Your code
}
[AllowAnonymous]
public ActionResult ForgotUsername()
{
//Your code
}
}
В хабе SignalR (ничего необычного, чем то, что есть в документации SignalR)
public override Task OnConnected()
{
SignalRConnectionStore.Add(Context.User.Identity.Name, Context.ConnectionId);
return base.OnConnected();
}
public override Task OnReconnected()
{
string name = Context.User.Identity.Name;
//Add the connection id if it is not in it
if (!SignalRConnectionStore.GetConnections(name).Contains(Context.ConnectionId))
{
SignalRConnectionStore.Add(name, Context.ConnectionId);
}
return base.OnReconnected();
}
public override Task OnDisconnected(bool stopCalled)
{
SignalRConnectionStore.Remove(Context.User.Identity.Name, Context.ConnectionId);
return base.OnDisconnected(stopCalled);
}
Это работает как для анонимных, так и для аутентифицированных пользователей.
SignalRConnectionStore класс и интерфейс
public interface ISignalRConnectionStore
{
int Count { get; }
void Add(string userName, string connectionId);
IEnumerable<string> GetConnections(string userName);
void Remove(string userName, string connectionId);
}
internal class SignalRConnectionStore : ISignalRConnectionStore
{
private readonly Dictionary<string, HashSet<string>> _connections = new Dictionary<string, HashSet<string>>();
public int Count
{
get
{
return _connections.Count;
}
}
public void Add(string userName, string connectionId)
{
if (!string.IsNullOrEmpty(userName) && !string.IsNullOrEmpty(connectionId))
{
lock (_connections)
{
HashSet<string> connections;
if (!_connections.TryGetValue(userName, out connections))
{
connections = new HashSet<string>();
_connections.Add(userName, connections);
}
lock (connections)
{
connections.Add(connectionId);
}
}
}
}
public IEnumerable<string> GetConnections(string userName)
{
if (!string.IsNullOrEmpty(userName))
{
HashSet<string> connections;
if (_connections.TryGetValue(userName, out connections))
{
return connections;
}
}
return Enumerable.Empty<string>();
}
public void Remove(string userName, string connectionId)
{
if (!string.IsNullOrEmpty(userName) && !string.IsNullOrEmpty(connectionId))
{
lock (_connections)
{
HashSet<string> connections;
if (!_connections.TryGetValue(userName, out connections))
{
return;
}
lock (connections)
{
connections.Remove(connectionId);
if (connections.Count == 0)
{
_connections.Remove(userName);
}
}
}
}
}
}
Объявите статическую переменную SignalRConnectionStore в классе Hub, как показано ниже.
public class ProvisioningHub : Hub
{
private static ISignalRConnectionStore SignalRConnectionStore;
public ProvisioningHub(ISignalRConnectionStore signalRConnectionStore)
: base()
{
SignalRConnectionStore = signalRConnectionStore; //Injected using Windsor Castle
}
}
