我遇到了一些基本配置问题，试图让我的第一个 SignalR 应用程序正常工作。它正在生成一个代理，但其中没有集线器，我什至不能调用 createHubProxy()，由于某种原因，该函数在我的代理中不存在。
我在 Application_start 中调用 RouteTable.Routes.MapHubs()，我也尝试在 web.config 中进行设置。我究竟做错了什么？
这是一个简单的“ol Web Forms”应用程序。我的aspx代码：
<%@ Page Language="C#" CodeFile="blogroll3.aspx.cs" Inherits="blogroll3" %>
<!DOCTYPE html>
<html>
<head id="Head1" runat="server">
<script src="http://ajax.aspnetcdn.com/ajax/jQuery/jquery-1.10.2.min.js"></script>
<script src="/scripts/jquery.signalR-1.1.3.js"></script>
<script src='<%: ResolveClientUrl("~/signalr/hubs") %>'></script>
<script src="blogroll3.js"></script>
</head>
<body>
</body>
</html>
代码隐藏：
using System;
using System.Web.UI;
using Microsoft.AspNet.SignalR;
using Microsoft.AspNet.SignalR.Hubs;
public partial class blogroll3 : Page
{
public class ProgressHub : Hub
{
public void setProgress()
{
}
}
}
我的客户端js代码：
//this is not working, progressHub is undefined:
//var proghub = $.connection.progressHub;
//this code fails on createHubProxy(), it doesn't exist.
var connection = $.hubConnection();
var proghub = $.connection.createHubProxy('progressHub');
这是它生成的代理：
