signalR CORS - IE client gets 403 'Forbidden: JSONP is disabled'

We implemented SignalR 2.0 hub with CORS enabled. Javascript clients on Firefox and Chrome are running fine. IE 10 gets error 403. Any help will be appreciated. Thank you and regards. halter73 While IE 10 (but not IE ≤9) should support CORS, if you find yourself needing to use JSONP you can enable it when you call MapSignalR . Enabling JSONP allows your SignalR app to be accessed from any origin while sending cookies/credentials. With CORS, you can limit which origins are able to access your SignalR app, whether or not cookies/credentials should be sent with cross-origin requests and more.

SignalR Groups not getting data

Hi I am having a problem where my signalR clients who are in a group do not get the information sent. I have tried this in two ways and both not working. On web page loaded the client will call the server to get the group name and then call a method on the hub to join the user in that group. JavaScript..... var connectionOpen = false; var myHub; $(function () { myHub = $.connection.myHub; myHub.client.showMessage = alertMessage; $.connection.hub.start(function () { connectionOpen = true; joinGroup(); }); }); function joinGroup() { $.ajax({ url: 'Controller/GetGroupName, type: 'POST', success:

Can someone provide a CorsPolicy implementation with an explicit Origins list?

由 拈花ヽ惹草 提交于 2019-12-06 07:59:30
问题 Referring to the SignalR Hubs API Guide indicates the following information in the configuration comments: // Setup the CORS middleware to run before SignalR. // By default this will allow all origins. You can // configure the set of origins and/or http verbs by // providing a cors options with a different policy. map.UseCors(CorsOptions.AllowAll); however, the Origins property of System.Web.CorsPolicy has a private setter, no constructor that allows origins to be injected, and no exposed

Best Practices for reconnecting a disconnected SignalR client (JS)

由 拥有回忆 提交于 2019-12-06 06:45:07
问题 I'd like to improve the resilience of my clientside implementation of a signalR client. Currently, I do this: hub.server.sendClientNotification(string, appSettings.username()); However occasionally, an exception related to connectivity is thrown because either the server is not responding or the client's internet connection has become unusable. I'd like to solve this by queuing up requests and then doing something like this: try { // pop from queue hub.server.sendClientNotification(string,

SignalR and serializing object array

由 我怕爱的太早我们不能终老 提交于 2019-12-06 06:44:26
问题 I'm new to SignalR and have done a simple test hack. I wish to serialize an object array with typed objects. By default SignalR has configured the JSon.NET serializer to not provide with type information. And I found that I could register a custom serializer in the DependencyResolver by: var serializer = new EventHubJsonSerializer( new JsonSerializerSettings { PreserveReferencesHandling = PreserveReferencesHandling.Objects, TypeNameHandling = TypeNameHandling.Objects }); GlobalHost
