我正在使用SignalR.But有一个关于超时的问题.
几分钟后超时消失,无法正常工作.
如何在SignalR 2.0中设置超时连接？
解决方法
您可以在Owin Startup类中使用以下配置.
// Make long polling connections wait a maximum of 110 seconds for a
// response. When that time expires,trigger a timeout command and
// make the client reconnect.
GlobalHost.Configuration.ConnectionTimeout = TimeSpan.FromSeconds(40);
// Wait a maximum of 30 seconds after a transport connection is lost
// before raising the Disconnected event to terminate the SignalR connection.
GlobalHost.Configuration.DisconnectTimeout = TimeSpan.FromSeconds(30);
// For transports other than long polling,send a keepalive packet every
// 10 seconds.
// This value must be no more than 1/3 of the DisconnectTimeout value.
GlobalHost.Configuration.KeepAlive = TimeSpan.FromSeconds(10);
//Setting up the message buffer size
GlobalHost.Configuration.DefaultMessageBufferSize = 500;
此外,当您希望始终将客户端连接到服务器时,可以尝试在disconnect hub事件中连接它.
var tryingToReconnect = false;
$.connection.hub.disconnected(function () {
//TODO: write the logic to reconnect to server.
if(!tryingToReconnect) {
// notifyclient about disconnection
setTimeout(function() {
$.connection.hub.start();
},5000); // Restart connection after 5 seconds.
}
});
$.connection.hub.reconnecting(function() {
tryingToReconnect = true;
console.log("reconnecting...");
});
$.connection.hub.reconnected(function() {
tryingToReconnect = false;
console.log("Reconnected");
});
