SignalR with IIS 10 and ARR 3.0

由 流过昼夜 提交于 2019-12-08 10:04:50
问题 We can't get SignalR to work when using ARR 3.0 as a reverse proxy in front of our Visual Studio development machine. The connection is successfully established but the initial frame that should be sent from the SignalR server once the connection is established is never sent, as a matter of fact, no frames can be sent, this causes the client to drop the WebSocket connection. To sum up, "the websocket connection can establish, but can't transfer frames." The MVC app works without the reverse

问题 I want to push a notification from my server to client.

Using StructureMap for dependency injection to SignalR 2.0.1

由 ぃ、小莉子 提交于 2019-12-08 08:34:32
I'm trying to use StructureMap for dependency injection to a SignalR hub. Many sources in the internet say this should be done as in this answer: How do you Resolve signalR v2.0 with StructureMap v2.6 . I tried it, and got it to work - at least for the first action after the first pageload. When I try to leave the HTML page that includes the SignalR-JS-Code (or reload the page), or when I use one of the functions defined in my hub a second time, I get this StructureMapException: You cannot use the HttpContextLifecycle outside of a web request. Try the HybridLifecycle instead. in the public

How to buffer messages on signal hub and send them when the right client appears?

由 风格不统一 提交于 2019-12-08 07:52:45
问题 I hawe two type of clients connecting my signalR server (ASP.NET Core). Some of them are senders, and some of them are receivers. I need to route messages from senders to the receivers, which is not a problem, but when there is no receivers, I need to somehow buffer messages and not lose them (probably the best is ConcurrentQueue in some kind of a singleton class) but when the first receiver connect, the message buffer needs to start dequeue. Which is the best approach for this? I created

I have successfully developed an hub for my newsletter sending function in a .net website. The server procedure is called by the hub, then during the sending routine, I send a client methods to report the progress status, and finally another client method to report ending of the routine. My dev environment is win10 with IIS 10, VS2013, .NET 4.5 SignalR 2.2.0. I can use websocket in my dev and work fine, but my production server is win 2008r2 (IIS 7.5), so I must use serverSentEvents, working as well on dev. Here my client code: $.connection.hub.logging = true; hubConn = $.connection
