没有生成集线器文件。我得到了最常见的javascript错误，也显示在图片中。

请就此提出建议。代码是来自microsoft docs的示例代码。 教程：SignalR 2入门| Microsoft Docs [ ^ ]



我尝试过：



我搜索并找到了许多解决方案，但似乎没有任何效果。比如更改参考src等。

以下是我引用脚本文件的方法。

 < span class =code-leadattribute>< script     src   =  Scripts / jquery-3.3.1.min.js >  < /   script  >  
 
<！ - 参考SignalR库。 - > 
 < script     src   =  Scripts / jquery.signalR-2.2.2.min.js >  < /   script  >  
<！ - 引用自动生成的SignalR集线器脚本。 - > 
 < script     src   ='  <％：ResolveClientUrl（ 〜/ signalr / hubs）％> '  >  < /   script  >  

解决方案

终于得到了答案。我正在尝试上网的所有可能的事情，然后有一件事情有效。这就是这一行[HubName（myHub）] ..之前我的名字是[HubName（MyHub）]，所以错误。

 [HubName（  myHub）] 
 
  public   class  MyHub：Hub 
 {
 
  public   void 发​​送（ string  name， string  message）
 {
  //  调用broadcastMessage方法来更新客户端。 
 Clients.All.broadcastMessage（name，message）; 
} 

您需要定义与javascript中使用的HubName相同的内容，以便在获取客户端时不会产生任何混淆。

  var  chat = 

.connection.myHub;

Here is the screenshot of runtime project that contains signalR.

There is no hubs file generated. I am getting the most common javascript error That is also shown in picture.
Please advice something on this. The code is the sample code from microsoft docs. Tutorial: Getting Started with SignalR 2 | Microsoft Docs[^]

What I have tried:

I searched and found many solutions but nothing seems to work. like changing reference src and etc.
Here is how I am referencing the script files.

<script src="Scripts/jquery-3.3.1.min.js"></script>

    <!--Reference the SignalR library. -->
    <script src="Scripts/jquery.signalR-2.2.2.min.js"></script>
    <!--Reference the autogenerated SignalR hub script. -->
    <script src='<%: ResolveClientUrl("~/signalr/hubs") %>'></script>

解决方案

Finally got the answer. I was trying every possible thing I got on internet and then one thing worked. and that was in this line [HubName("myHub")].. I had this name as [HubName("MyHub")] before and so the error.

[HubName("myHub")]

public class MyHub : Hub
{
  
    public void Send(string name, string message)
    {
        // Call the broadcastMessage method to update clients.
        Clients.All.broadcastMessage(name, message);
    }

You need to define HubName same as you used in javascript so that there wont be any confusion in getting client.

var chat =

.connection.myHub;
