signalr.client

问题 I have a parent and child viewModel. The parent viewmodel starts the signalR connection: $.connection.hub.start() The child viewmodel - one that loads only when the user accesses chat - does the following: chat.server.addUserToChat(self.currentUsername()).done(function() { alert('added'); }); The problem is, the child call is happening before the parent call. I can fix this with a setTimeOut of 1 second, but ideally I could do something like this: $.connection.hub.ready(function(){chat.server

问题 This thing is dragging me nuts. I have a .net 4.0 console app and I have an MVC web app. javascript clients can connect and talk to the server - no problems here... but my .net client throws System.AggregateException with InnerException = "Unexpected character encountered while parsing value: <. Path... so I created an empty MVC3 app, added SignalR libraries, and .net client surprisingly connects to that. But for some reason it doesn't to the other one. I've checked everything, both MVC3 apps

问题 I'm using SignalR to transferring commands from client to server without refreshing the page. When the client enter some of my web pages, I'm starting a new hub connection. Like this: var hub = $.connection.siteControllerHub; $.connection.hub.start(); This "start()" function takes some time (+-5 seconds). mean while, the page is already finished loading and the user start using my UI. SingalR cannot serve the user, until it's finish loading the connection. I'm know that I'm can use the async

问题 My understanding is that with signalr I can just send objects back and forth. I am trying to set up a .net client to receive notifications that orders have been placed on a web site. I am trying to set up a very simple example so that I understand the concepts. It works great when I am sending a string notification back to the client, but when I try to send an object I get an error: Microsoft.CSharp.RuntimeBinder.RuntimeBinderException was unhandled by user code HResult=-2146233088 Message

问题 Using SignalR, is there any possibility to call .fail instead of .done when specific values are returned by hub method? Perhaps using the SignalR pipeline? public bool Delete(int addressId) { // User should not be able to delete default address if(AddressService.IsDefaultAddressOfCustomer(addressId)) return false; // Should call .fail() on client AddressService.Delete(addressId); return true; // Should call .done() on client } The alternative would be to throw an exception but I would like to

问题 Using SignalR for ASP.NET Core 2.0, Client side (1.0.0-alpha2-final), C# VS2017. To connect the code is: await hubConnection.StartAsync(); since this is an await for a void how can we test if the client did manage to connect ? In my tests I have a breakpoint on the server side in public override async Task OnConnectedAsync() but that breakpoint is not always hit therefore I know that sometimes the client does not connect. Or perhaps it did connect but OnConnectedAsync() was not triggered? How

问题 I have a MVC .NET application that uses signalR. I tried to download this client: https://github.com/Gurgen/SignalR-.net-core-android-client I ran it on my device. Pressed the connect button. But kept getting an exception. Debugging it I found that I had to change this line String connectionId = jsonElement.getAsJsonObject().get("connectionId").getAsString(); to this String connectionId = jsonElement.getAsJsonObject().get("ConnectionId").getAsString(); I am already starting to feel like this

问题 Using .NET Core 2.1 & VS2017 preview 2 I created a simple web server with "Identity as UI" as explained here and then added a SignalR chat following this. In particular I have: app.UseAuthentication(); app.UseSignalR((options) => { options.MapHub<MyHub>("/hubs/myhub"); }); .. [Authorize] public class MyHub : Hub .. "iisSettings": { "windowsAuthentication": false, "anonymousAuthentication": true, "iisExpress": { "applicationUrl": "http://localhost:5000", "sslPort": 0 I start the debugger which

问题 I have an MVC website sitting onto of some fairly hefty business objects. My MVC Controllers call Manager objects which conducts and delegates work off to other sets of objects. Basically the code is deep server side, while a Hub in a way is just like a Controller in that it is fairly close to the client side. Is there a way to execute SignalR methods based on a reference to the Hub passed to these Manager objects? 回答1: If your MVC and SignalR services are running on the same process, you can

问题 I'm attempting to migrate our ASP.Net MVC application from using Signal R1.x tgo SignalR 2.x. I just found issue which will certainly cause us problems in our quest to move forward. Our web application is MVC based and makes heavy use of the HttpContext.Current.Session variable. When running with SignalR 1.x, everything is fine and dandy with Session. When we upgraded to SignalR 2.x, Session was suddenly null. I did a little googling and found the following links regarding the issue:
