问题描述

我使用的 SignalR 是 ASP.NET 4.5 web表单。我是不是能够使客户与服务器，反之亦然。我想实现的是仅仅是能够测试客户端如何能够触发服务器功能，以及如何在服务器可以触发客户端功能。这里的code我使用：

I'm using SignalR with ASP.NET 4.5 webforms. I wasn't able to make the client talk to the server and vice versa. What I want to achieve is simply being able to to test how the Client can trigger a server function and how the server can trigger a client function. Here's the code I use:

客户端code（HitCounter.aspx）

<html xmlns="http://www.w3.org/1999/xhtml">
<head runat="server">
<title></title>
<script type="text/javascript" src="Scripts/jquery-1.8.2.js"></script>
<script src="Scripts/jquery.signalR-0.5.3.min.js"></script>
<script type="text/javascript" src="SignalR/Hubs"></script>

<style>
    #currentHitCount {
        font-family: Arial;
        font-size:40pt;
        margin-left:auto;
        margin-right:auto;
        display:block;
        text-align:center;
    }

</style>
</head>
<body>
<div id="currentHitCount"></div>
<script type="text/javascript">

    $(function () {
       var hub = $.connection.hitCounter;

       $.extend(hub, {
           showHitCount: function (hitCount){
               if(hitCount > 1){
                   $('#currentHitCount')
                   .html("This site has had " + hitCount + " hits.");
               }
               else{
                   $('#currentHitCount')
                   .html("This site has had " + hitCount + " hit.");
               }
           },
           addMessage: function (str) {
               $('#currentHitCount')
               .html("Getting Message: " + str);
           }
       });

       $.connection.hub.start(function () {
           hub.addMessage("test");
           hub.addHit();

       });

       $.connection.hub.stateChanged(function (change) {
           if ($.signalR.connectionState["connected"] === change.newState) {                  
           }
       });

       $.connection.hub.error(function () {
       });

   });


   </script>
  <div style="background-color:red; width:290px; height:200px; color:white; position:absolute; top:100px; left:30px;" id="thebutton">test</div>

</body>
</html>

服务器端code（APP_ code / HitCounterHub.cs）

using SignalR.Hubs;
using System;
using System.Collections.Generic;
using System.Linq;
using System.Threading.Tasks;
using System.Web;

[HubName("hitCounter")]
public class HitCounterHub : Hub, IDisconnect
{
    static int _hitCount;

public void addHit(string pageId)
{
    _hitCount += 1;
    Clients.showHitCount(_hitCount);

}

public Task ClientCallingServer()
{
    _hitCount += 1;
    return Clients["foo"].showHitCount(_hitCount);
}


public Task Join()
{
    return Groups.Add(Context.ConnectionId, "foo");
}

public Task Send(string message)
{
    _hitCount += 1;
    return Clients["foo"].addMessage(message);       
}


public Task Disconnect()
{
    return Clients["foo"].leave(Context.ConnectionId);
}
}

我在本地运行code对IIS7.5但我得到并运行在Visual Studio 2012太code时的错误。

I am running the code locally on IIS7.5 but I get and error when running the code in Visual Studio 2012 too.

该错误：

localhost/signalr/signalr/send?transport=serverSentEvents&connectionId=400f1302-6c8e-418e-a14c-da95f836a29d
500（内部服务器错误）

使用Chrome调试器的错误页面显示：
addHit'方法无法解析。

Using Chrome debugger the error page shows:'addHit' method could not be resolved.

再次什么，我试图做的是做一个简单的测试来检查如何调用从客户端从服务器服务器和客户端。

Again, what I am trying to do is to make a simple test to check how to call a server from the client and the client from the server.

感谢。
