如何从SignalR客户端端确定服务器断开连接

Answer 1

　　1. 集线器有disconnect这将允许您添加一个回调函数，当断线发生：myHub.disconnect(function() {
alert('Server has disconnected');
});

如果你阿仁'枢纽然后为代码将帮助你：$(connection).bind("onDisconnect", function (e, data) {
callback.call(connection);
});

这显示了语法钩到底层连接的触发OnDisconnect事件。
2. 如果集线器那么IDisconnect接口。public class ChatHub : Hub, IDisconnect
{
public void Disconnect()
{
Debug.WriteLine(Context.ConnectionId + " disconnected");
}
}

对持续连接可以覆盖OnDisconnectAsync， （从SignalR维基于）public class MyEndPoint : PersistentConnection
{
protected override Task OnDisconnectAsync(string clientId)
{
return Connection.Broadcast("Client " + clientId + " disconncted");
}
}

3. 开始与SignalR v0.5.1它的工作原理是这样的：$.connection.hub.stateChanged(function (change) {
if (change.newState === $.signalR.connectionState.reconnecting) {
console.log("liveFeed is reconnecting!");
}
else if (change.newState === $.signalR.connectionState.connected) {
console.log("liveFeed is connected!");
}
});
