signalr

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? 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 = ...; // your serialized data var jsonBytes = new ArraySegment<byte>(Encoding.UTF8.GetBytes(jsonString));

I've just started with SignalR and would like to try out the real time notifications. The objective is to keep displaying the updated message on web page. There is a database table - DummyData with a column Message . This table has only one record - Hello When the page loads, "Hello" is displayed. I then manually run the command in sql server 2012 update DummyData set Message='hello world' , but the message isn't updated in the webpage. aspx: <script> $(function () { var notify = $.connection.notificationsHub; $.connection.hub.start().done(function () { notify.server.notifyAllClients(); });

1. 添加 SignalR 客户端库 右键点击项目->然后选择“添加” >“客户端库” 提供程序选择： unpkg ，库选择： @aspnet/signalr@1.1.4 选择“选择特定文件” ，展开“dist/browser” 文件夹，然后选择“signalr.js” 和“signalr.min.js” 选择指定位置安装即可 2.定义Hub集线器 创建MessageHub 并继承Hub。 Hub 类管理连接、组和消息 using System.Collections.Generic; using System.Threading.Tasks; using Microsoft.AspNetCore.SignalR; namespace NetCoreWebApi.SignalR { /// <summary> /// Message集线器 /// </summary> public class MessageHub : Hub { /// <summary> /// 存放已连接信息 /// </summary> public static readonly Dictionary<string, string> Connections = new Dictionary<string, string>(); /// <summary> /// 发送消息 /// </summary> /

I want to use pub-sub messaging between multiple servers in a web farm to maintain their local (ASP.NET) caches in sync. Could this be easily done with SignalR? If it is possible, how can I do so? 来源： https://stackoverflow.com/questions/9449601/does-signalr-support-the-publish-subscribe-messaging-paradigm

My application will often be used under fucked up corporate networks (proxy, firewalls, etc.) so I can not rely on sockets and long-polling is practically my only option. Here is my biggest problem with long-polling: Long-polling is disconnected at some point of time I automatically reconnect (accoring to documentation) User clicks something that causes hub method call but connection is not established yet - error happens. Is there any way to synchronize hub method call and reconnection like: I call hub method SignalR sees connection is not ready yet It waits till connection is ready and calls

I have an MVC application running under .NET 4.5 on a WebRole on Windows Azure, employing SignalR 1.0 -alpha2, and using the ServiceBus backplane. In my App_Start folder I have RegisterHubs.cs, as follows: [assembly: PreApplicationStartMethod(typeof(pageengine.studio.RegisterHubs), "Start")] namespace pageengine.studio { public static class RegisterHubs { public static void Start() { // Register the default hubs route: ~/signalr/hubs RouteTable.Routes.MapHubs(); } } } And in Global.asax, I have the following: protected void Application_Start() { AreaRegistration.RegisterAllAreas();
