signalr在.net mvc的客户端中不起作用

Question

我在我的.net mvc项目浏览器日志中使用signalr是：

18:01:35 GMT+0330 (伊朗标准时间) SignalR:客户端订阅了集线器‘通知中心’。jquery.signalR-2.2.1.min.js:9:3362

18:01:35 GMT+0330 (伊朗标准时间) SignalR:与'/signalr/negotiate?clientProtocol=1.5&connectionData=%5B%7B%22name%22%3A%22notificationhub%22%7D%5D'.谈判jquery.signalR-2.2.1.min.js:9:3362

18:01:35 GMT+0330 (伊朗标准时间) SignalR: webSockets传输已连接。正在启动启动请求。jquery.signalR-2.2.1.min.js:9:3362

18:01:35 GMT+0330 (伊朗标准时间) SignalR:启动请求成功转换到已连接状态。jquery.signalR-2.2.1.min.js:9:3362

18:01:35 GMT+0330 (伊朗标准时间) SignalR:现在监控保持连接，警告超时为13333.333333333332，保持连接超时为20000，断开连接超时为30000

18:12:40 GMT+0330 (伊朗标准时间) SignalR:触发集线器'notificationHub‘上的客户端集线器事件'receiveNotification’

问题出在哪里？

客户端代码：

​

<script>
    $(function () {

        $.connection.hub.logging = true; 
        var notificationHub = $.connection.notificationHub;
    
          notificationHub.client.receiveNotification = function (message, userID, link) {

            showNotification('new message', message, link);
        };
        $.connection.hub.start(); 
        

    });


    $.connection.hub.disconnected(function () {
        setTimeout(function () {
            $.connection.hub.start();
        }, 5000); // Restart connection after 5 seconds.
    });

</script>




<script type="text/javascript">
        function notify(title,message,link) {
           
            var option = {
                body: message,
                dir: 'rtl',
                title:title,
                icon:'/Content/Images/notification.png',

            }

            var notify = new Notification(title, option);
            

            notify.onclick = function () {
                window.open(link, '_blank');
                notify.close();
            };

            

        }

        function showNotification(title, message, link) {

            if (!("Notification" in window)) {

                
                //alert('Your browser does not support Notification');

            } else if (Notification.permission === "granted") {

                notify(title, message, link);

            } else if (Notification.permission !== "denied") {

                Notification.requestPermission(function (permission) {

                    if (permission === "granted") {

                        notify(title, message, link);

                    }

                });

            }

        }
    </script>
