signalr

问题 I built server and client code that uses SignalR. The website is working perfectly, but I can't see the web traffic in any browser (chrome, IE, Firefox). I know the web traffic is there because the website is working. Is there a way to view SignalR Traffic in a browser? If not what is the best external tool for viewing SignalR traffic? 回答1: you can use Fiddler, see this article : https://github.com/SignalR/SignalR/wiki/Using-fiddler-with-signalr 来源： https://stackoverflow.com/questions

问题 I've one SignalR hub that manages one type of messaging. I need to add a second hub to the same page which is just a post a message and returns to the rest of the clients and a posted message. Is it possible to have multiple hubs for one connection? The deal is that if one hub is started before the others how do I connect or subscribe to the current hub if the first hub has already started the connection? They are both a messaging type of hub but one many or may be used. How do I approach

问题 In my Startup.Auth.cs : private static void ConfigSignalR(IAppBuilder appBuilder) { appBuilder.MapSignalR(); var idProvider = new PrincipalUserIdProvider(); GlobalHost.DependencyResolver.Register(typeof(IUserIdProvider), () => idProvider); } My UserHub.cs : public class UserHub : Hub { } On the server-side, in one of my API Controller action (a Put related to a Grid Update): [...] var userHub = GlobalHost.ConnectionManager.GetHubContext<UserHub>(); // Line below does not work // userHub

问题 Is there a reason why the Java client for SignalR only supports exactly version 1.3? https://github.com/SignalR/java-client/blob/f226631da562cfaacbe8b16d5a9ecbf8205e7c99/signalr-client-sdk/src/microsoft/aspnet/signalr/client/Connection.java#L597 Shouldn't all clients be backwards compatible? Is there any harm done and changing the verifyProtocolVersion method to verify that the protocol is less than or equal to 1.3? For testing purposes, I simply returned true, skipping the entire method body

问题 I am trying to learn signalR and i have a little test working.

问题 I have some problem with signalR, I can not send message to specific User From Hub.
