Javascript 信号器一个连接多个集线器、多个处理器

理想情况下，我希望建立一个到多个集线器的连接，但在连接启动后注册客户端处理程序

工作原理：

• 每个集线器有多个连接，并在连接之前注册处理程序-我希望尽可能减少连接，也可能不知道/不想事先注册所有处理程序
• 每次都得停下来又开始 注册新消息-这是有问题的，因为您可能会在其他地方中断另一条消息

什么不起作用：

• 使用官方文档“在客户端上定义方法（无 生成的代理，或在调用start方法后添加时） -只有将处理程序添加到先前已启动的同一集线器连接时，此操作才有效。如果启动到新集线器的连接，新处理程序将不会注册，因为集线器以前没有连接到OnConnect的处理程序
• 偶然发现这个网站 但他的实现也不起作用。我可能做了些什么 错误地
