signalr

问题 I'm working on an asp.net mvc project where we use SignalR for real time connection in different views. Works great, apart from the fact that the execution of javascript stops if there's a problem with SignalR. Typically, this error would be a problem if my self hosting application is down, or other connection issues has occured. GET http://localhost:8081/signalr/hubs net::ERR_CONNECTION_REFUSED List:328 Uncaught TypeError: Cannot read property 'client' of null As mentioned, if this has

问题 I am attempting to authorize SignalR requests exactly using the sample project here AngularJS Authentication based on this project AngularJS Authentication using web tokens. The problem I am having is, to use SignalR authorization, I had to override the SignalR AuthorizeAttribute class as below: public class QueryStringBearerAuthorizeAttribute : AuthorizeAttribute { public override bool AuthorizeHubConnection(HubDescriptor hubDescriptor, IRequest request) { var token = request.QueryString.Get

问题 In Application_Start of Global.asax i have the following ObjectFactory.Initialize(cfg => { cfg.For<IDependencyResolver>().Singleton().Add<StructureMapDependencyResolver> (); }); My Interface for the Hub is public interface IDashboardHub { void Initialize(); } and my hub is as follows: public class DashboardHub : Hub, IDashboardHub { private readonly ICpeAccountService _accountService; public DashboardHub(ICpeAccountService service) { _accountService = service; } [Authorize] public void

问题 In an MVC project, I have a method on a hub similar to this: public string Foo() { return DoCrazyThingThatReturnsJson(); } Unfortunately SignalR (or something) takes the encoded JSON string and happily encodes it, then returns it, so browser be like LOLWTF. Is there a way to skip this second encoding? 回答1: Looking at this here: We assume that any ArraySegment is already JSON serialized it seems like something like this may work (note that I haven't tried it, so no promises): string jsonString

问题 On my server side I'm using web api 2 with signalr. On my client side I'm using angularjs.

问题 I am starting on signalR with asp.net webapi, and I am trying to understand the whole signalR request/connection pipeline and what is the lifetime of the hub and who creates and dispose the hub instance (does it gets created on every communication between client and server?) One of the reason is that we need to understand how we should be using an IoC contain in signalR request scenario, how we control the lifetime of the dependency correct specifically the ISession or DBContext . 回答1: Hubs

问题 I am using signalr (version 2.0.0) in my asp.net mvc4 webapi project, Here to allow cross origin resource sharing, i use the following code in webconfig file <customHeaders> <add name="Access-Control-Allow-Origin" value="*" /> <remove name="X-Powered-By" /> </customHeaders> Here is the client side signalr code for receiving data from server: $(function () { var nodePublishingHub = $.connection.nodePublishingHub; nodePublishingHub.client.NodePublished = onNewMessage; $.connection.hub.error
