Asp.net SignalR simplifies real-time communication. 2. Ship SignalR to the console, and signalr becomes simple.

In Asp.net SignalR, real-time communication becomes simple. Siming shares a SignalR directly hosted on IIS. SignalR can also host in any application, including the console, client programs and Windows Services. Mono is also supported, which means that it can be deployed across platforms in Linux.

In my reference blog [SignalR of Asp.net Development Series] Topic 1: article 4 of Asp.net SignalR Quick StartHow to Use Asp.net SignalR in a desktop programThat is, boarding SignalR In the WPF client. I have already personally experienced it and it is quite helpful. If you want to know it, you can study it. Today, I will share with you how to directly host SignalR on the console.

1. Create a console application

2. Right-click the project you created and choose manage NuGet packages --> SearchMicrosoft. Owin. CorsAnd install --> SearchMicrosoft. AspNet. SignalR. SelfHostAnd install

　　

To be installedMicrosoft. AspNet. SignalR. SelfHostThe following figure shows readme.txt automatically displayed in. It details how to host SignalR to the console.

3rd, we can follow the instructions in readme.txt. Modify Program. cs as follows:

using Microsoft.AspNet.SignalR;using Microsoft.Owin.Cors;using Microsoft.Owin.Hosting;using Owin;using System;namespace SelfSignalRSvc2._0{    public class Program    {        static void Main(string[] args)        {            // This will *ONLY* bind to localhost, if you want to bind to all addresses            // use http://*:8080 or http://+:8080 to bind to all addresses.             // See http://msdn.microsoft.com/en-us/library/system.net.httplistener.aspx             // for more information.            using (WebApp.Start<Startup>("http://localhost:118/"))            {                Console.WriteLine("Server running at http://localhost:118/");                Console.ReadLine();            }        }    }    public class Startup    {        public void Configuration(IAppBuilder app)        {            app.Map("/signalr", map =>            {                // 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);                var hubConfiguration = new HubConfiguration                {                    // You can enable JSONP by uncommenting line below.                    // JSONP requests are insecure but some older browsers (and some                    // versions of IE) require JSONP to work cross domain                    // EnableJSONP = true                };                // Run the SignalR pipeline. We're not using MapSignalR                // since this branch is already runs under the "/signalr"                // path.                map.RunSignalR(hubConfiguration);            });        }    }}

Create a ChatHub class, inherit from the Hub, and implement the following code:

Using Microsoft. aspNet. signalR; using System. diagnostics; using System. threading. tasks; namespace SelfSignalRSvc {public class ChatHub: hub {// <summary> /// server code for the client to call /// </summary> /// <param name = "message"> </param> public void Send (string message) {var name = Context. connectionId; // call the sendMessage method Clients of all Clients. all. sendMessage (name, message );} /// <summary> // called when the client is connected /// </summary> /// <returns> </returns> public override Task OnConnected () {Trace. writeLine ("client connection successful:" + Context. connectionId); return base. onConnected ();}}}

4. According to the above operations, we have completed the development of the script service. Run VS directly. The console is started successfully.

5. Create an html code to verify whether the script is available.

Remember to reference the jquery-1.10.2.js and jquery. signalR-2.2.2.min.js while modifying the link to the script http: // localhost: 118/signalr/hubs and

The host service address must be specified.$. Connection. hub. url = 'HTTP: // localhost: 118/signalr ';

<! DOCTYPE html> 
You can directly run the html page of the web site and open multiple web pages to receive the same message .. As follows:

 
By boarding signalR to the WPF client, you can see that the two implementations are similar. Therefore, in actual use, you can select an implementation method that suits your needs.
