html代码:
<script src="~/Scripts/jquery.signalR-2.2.0.min.js"></script>
<script src="@Url.Content("~/signalr/hubs")" type="text/javascript"></script>
<script>
$(function () {
var hub = $.connection.payHub;
hub.client.waitNotify = function (tran, url) {
console.log("waitNotify:" + tran + " " + url);
if (tran) {
location.href = url;
} };
$.connection.hub.start().done(function () {
console.log("hub done");
});
})
</script>
hub代码：
[HubName("payHub"), Authorize]
public class payHub : Hub
{
public static Dictionary<Guid, string> userPayHub = new Dictionary<Guid, string>();
public static void Notify(Guid userId, string redirectUrl)
{
if (userPayHub.ContainsKey(userId))
{
Microsoft.AspNet.SignalR.GlobalHost.ConnectionManager.GetHubContext<Hubs.payHub>()
.Clients.Client(Hubs.payHub.userPayHub[userId])
.waitNotify(true, redirectUrl);
}
}
public override Task OnConnected()
{
var uid = this.Context.User.Identity.GetUserId();
userPayHub[uid] = this.Context.ConnectionId;
return base.OnConnected();
}
public override Task OnDisconnected(bool stopCalled)
{
var uid = this.Context.User.Identity.GetUserId();
userPayHub.Remove(uid);
return base.OnDisconnected(stopCalled);
}
public override Task OnReconnected()
{
var uid = this.Context.User.Identity.GetUserId();
userPayHub.Remove(uid);
return base.OnReconnected();
}
}
通知调用Notify方法即可。
关键点：GlobalHost.ConnectionManager.GetHubContext
