SignalR doesn't work under Visual Studio 2017
Question
I don't know if it's VS2017 or what.. but I have simplest signalR app possible and It doesn't work. Here's my code, maybe you will find something:
I created Empty ASP.NET web application.
Added Startup class:
[assembly: OwinStartup(typeof(Connect4.Server.Startup))]
namespace Test.Server
{
public class Startup
{
public void Configuration(IAppBuilder app)
{
app.MapSignalR();
}
}
}
Added ChatHub:
namespace Test.Server
{
[HubName("chatHub")]
public class ChatHub : Hub
{
public void send(string message)
{
Clients.All.addMessage(message);
}
}
}
And "Default.aspx" :
<%@ Page Language="C#" AutoEventWireup="true" CodeBehind="Default.aspx.cs" Inherits="Test.Server.Default" %>
<!DOCTYPE html>
<html xmlns="http://www.w3.org/1999/xhtml">
<head runat="server">
<title>Signalr Chat Messenger</title>
<script src="Scripts/jquery-1.6.4.js"></script>
<script src="Scripts/jquery.signalR-2.2.2.js"></script>
</head>
<body>
<form id="form1" runat="server">
<script type="text/javascript">
$(function () {
var IWannaChat = $.connection.chatHub;
IWannaChat.client.addMessage = function (message) {
$('#listMessages').append('<li>' + message + '</li>');
};
$("#SendMessage").click(function () {
IWannaChat.server.send($('#txtMessage').val());
});
$.connection.hub.start();
});
</script>
<div>
<input type="text" id="txtMessage" />
<input type="button" id="SendMessage" value="broadcast" />
<ul id="listMessages">
</ul>
</div>
</form>
</body>
</html>
Can you see anything wrong? The website is opened with textbox and broadcast button.. but nothing happens after I click it.
BTW. I had to uncheck Enable JavaScript Debugging for ASP.NET (Chrome and IE). (in Tools > Options > Debugging > General > Enable JavaScript Debugging for ASP.NET (Chrome and IE) ), because of this problem

您需要添加hubs脚本
<script type="text/javascript" src="/signalr/hubs"></script>
