There is a confusion in the arrangement of codes and the place where it pleases so I hope to find an explanation for the following:
When I have a server "https://localhost:48009/" and the application is equipped with all the requirements of Signal-R and also Hub exists on it. in folder Hubs There is a Hub Class ChatHub.cs
using System; using System.Web; using Microsoft.AspNet.SignalR; namespace SignalRChat { public class ChatHub : Hub { public void Send(string name, string message) { // Call the addNewMessageToPage method to update clients. Clients.All.addNewMessageToPage(name, message); } } } and in Chat.cshtml
@{ ViewBag.Title = "Chat"; } <h2>Chat</h2> <div class="container"> <input type="text" id="message" /> <input type="button" id="sendmessage" value="Send" /> <input type="hidden" id="displayname" /> <ul id="discussion"> </ul> </div> @section scripts { <!--Script references. --> <!--The jQuery library is required and is referenced by default in _Layout.cshtml. --> <!--Reference the SignalR library. --> <script src="~/Scripts/jquery.signalR-2.1.0.min.js"></script> <!--Reference the autogenerated SignalR hub script. --> <script src="~/signalr/hubs"></script> <!--SignalR script to update the chat page and send messages.--> <script> $(function () { // Reference the auto-generated proxy for the hub. var chat = $.connection.chatHub; // Create a function that the hub can call back to display messages. chat.client.addNewMessageToPage = function (name, message) { // Add the message to the page. $('#discussion').append('<li><strong>' + htmlEncode(name) + '</strong>: ' + htmlEncode(message) + '</li>'); }; // Get the user name and store it to prepend to messages. $('#displayname').val(prompt('Enter your name:', '')); // Set initial focus to message input box. $('#message').focus(); // Start the connection. $.connection.hub.start().done(function () { $('#sendmessage').click(function () { // Call the Send method on the hub. chat.server.send($('#displayname').val(), $('#message').val()); // Clear text box and reset focus for next comment. $('#message').val('').focus(); }); }); }); // This optional function html-encodes messages for display in the page. function htmlEncode(value) { var encodedValue = $('<div />').text(value).html(); return encodedValue; } </script> } Everything works fine as you open the page on more than one browser
Here all operations occur within the server "https://localhost:48009/"
I happened to have another project on another server For example "http://localhost:18098/"
in index.cshtml
@{ ViewBag.Title = "index"; } <h2>Chat</h2> <div class="container"> <input type="text" id="message" /> <input type="button" id="sendmessage" value="Send" /> <input type="hidden" id="displayname" /> <ul id="discussion"> </ul> </div> @section scripts { <!--Script references. --> <!--The jQuery library is required and is referenced by default in _Layout.cshtml. --> <!--Reference the SignalR library. --> <script src="~/Scripts/jquery.signalR-2.1.0.min.js"></script> <!--Reference the autogenerated SignalR hub script. --> ///////////////////gotohub here <script src="https://localhost:48009//signalr/hubs"></script> <!--SignalR script to update the chat page and send messages.--> <script> $(function () { // Reference the auto-generated proxy for the hub. ///////Link to the other server var chat = $.connection.chatHub.url="https://localhost:48009/"; // Create a function that the hub can call back to display messages. chat.client.addNewMessageToPage = function (name, message) { // Add the message to the page. $('#discussion').append('<li><strong>' + htmlEncode(name) + '</strong>: ' + htmlEncode(message) + '</li>'); }; // Get the user name and store it to prepend to messages. $('#displayname').val(prompt('Enter your name:', '')); // Set initial focus to message input box. $('#message').focus(); // Start the connection. $.connection.hub.start().done(function () { $('#sendmessage').click(function () { // Call the Send method on the hub. chat.server.send($('#displayname').val(), $('#message').val()); // Clear text box and reset focus for next comment. $('#message').val('').focus(); }); }); }); // This optional function html-encodes messages for display in the page. function htmlEncode(value) { var encodedValue = $('<div />').text(value).html(); return encodedValue; } </script> } Here I also seem to apply solutions to similar problems. Is this method correct?
Knowing another server "http://localhost:18098/" It is also equipped Signal-R
I want to bring Hub content from there to another server Hub.

Add Nuget package SignalR
Add "Startup" Class to App_Start
Change your web.config as bellow
<appSettings> <add key="owin:AppStartup" value="YourProjectName.App_Start.Startup"/> </appSettings>Add Hub Folder under your project
Modify Hub Class As Bellow
namespace YourProjectName.ChatHub { [HubName("ChatHub")] public class ChatHub : Hub { [HubMethodName("Sendchat")] public void Send(String Message,String Touser) { Clients.Client(Touser).GotMessages(Message);//send messages to specific user //Clients.All.GotMessages(Message); //seln messages to all user String CName = Message; } [HubMethodName("hubconnect")] public void Get_Connect(String Name) { Clients.All.GotMessages(Name +" Connected Connection Id is "+ this.Context.ConnectionId); String CName = Name; } public override System.Threading.Tasks.Task OnConnected() { return base.OnConnected(); } public override System.Threading.Tasks.Task OnReconnected() { return base.OnReconnected(); } public override System.Threading.Tasks.Task OnDisconnected(bool stopCalled) { return base.OnDisconnected(stopCalled); } } }
Change your Cshtml as Bellow
<h2>Chat</h2> <div class="container"> <input type="text" id="name" placeholder="tousername"/> <input type="text" id="message" placeholder="message" /> <input type="button" id="sendmessage" value="Send" /> <input type="hidden" id="displayname" /> <ul id="discussion"></ul> </div> @section scripts{ <script src="~/Scripts/jquery.signalR-2.3.0.min.js"></script> <!--Add your jquery.signalR- version above--> <script src="~/signalr/hubs"></script> <script> $(function () { // Reference the auto-generated proxy for the hub. var chatProxy; chatProxy = $.connection.ChatHub; $('#displayname').val(prompt('Enter your name:', '')); chatProxy.client.GotMessages = function (Message) { alert(Message); $('#discussion').append('<div>'+Message+'</br></div>'); }; $.connection.hub.start().done(function () { try { $.connection.ChatHub.server.hubconnect($('#displayname').val()); } catch (e) { alert(e.message); } }); $('#sendmessage').click(function () { // Call the Send method on the hub. chatProxy.server.Sendchat($('#message').val(), $('#name').val()); // Clear text box and reset focus for next comment. $('#message').val('').focus(); }); }); </script> }
