SignalR 在客户端处理超时事件
SignalR handle timeout event on client side
我是 SignalR 的新手，我有一个网络应用程序可以使用这种技术与服务器通信（恕我直言，这非常酷）。
我想知道的是 - 有没有办法在客户端使用 SingalR 处理超时事件？是否有超时事件被触发，我可以在客户端收听？
当我超时时，我可以在他的日志中看到：
[12:56:47 GMT+0300 (Jerusalem Daylight Time)] SignalR: Keep alive has been missed, connection may be dead/slow.
[12:56:54 GMT+0300 (Jerusalem Daylight Time)] SignalR: Keep alive timed out. Notifying transport that connection has been lost.
明确一点，我不想 运行 我自己的计时器并检查是否发生超时，我想问的是 SignalR 中是否有这样的事件被触发？
谢谢！
如你所见here$.connection.hub.disconnected
Handle the disconnected event to display a message when an attempt to
reconnect has timed out. In this scenario, the only way to
re-establish a connection with the server again is to restart the
SignalR connection by calling the Start method, which will create a
new connection ID. The following code sample uses a flag to make sure
that you issue the notification only after a reconnecting timeout, not
after a normal end to the SignalR connection caused by calling the
Stop method.
您可以通过$.connection.hub.disconnected事件处理程序管理连接超时：
$.connection.hub.disconnected(function() {
if(tryingToReconnect) {
notifyUserOfDisconnect(); // Your function to notify user.
}
});
如果你使用长轮询连接请注意，因为OnDisconnected()如果网络连接突然断开，它不会被调用
长轮询没有客户端保持活动检查，浏览器本身可能需要几分钟才能意识到连接确实已断开。
