Question

我有一些基本的配置问题试图让我的第一个SignalR应用程序工作。它正在生成代理，但是它没有集线器，我甚至无法调用createHubProxy（），由于某种原因，我的代理中不存在该函数。

我正在Application_start中调用RouteTable.Routes.MapHubs（），我也尝试在web.config中设置。我做错了什么？

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');

这是它正在生成的代理：

Answer 1

1）确保以下部分：@ Scripts.Render（“〜/ bundles / jquery”）在最新的signalr js文件之前被调用：jquery.signalR-2.0.2.min.js

2）如果您使用布局页面，请将@ Scripts.Render（“〜/ bundles / jquery”）移动到标题部分。

3）在撰写本文时，还要确保引用最新版本的signal-r：jquery.signalR-2.0.2.min.js

Answer 2

问题是我的Hub类嵌套在我的Page类中。搬出它解决了这个问题。请参阅我原来问题的评论。

Answer 3

我最终做的就是在浏览器中提取动态脚本

http://my app base url / signalr / hubs

然后当源出现时我完成了这些步骤

CTRL + A
CTRL + C
创建文件hubs.js
CTRL + V
用/hubs.js替换/ signalr / hubs

可能是野蛮而且过于简单。但是，它对我有用

Answer 4

对signalR R使用大写字母。

例如：

<script src="@Href("~/Scripts/jquery.signalR.js")" type="text/javascript"></script>

而不是：

<script src="@Href("~/Scripts/jquery.signalr.js")" type="text/javascript"></script>

SignalR不生成集线器类
