我目前正在快速使用SignalR,并尝试使用我对SignalR的基本理解来构建一个非常基本的消息通知系统,但我无法在之后收到消息。提交。
我已经阅读了很多关于这个主题的博客,最基本的是有一个接受字符串值的VOID方法然后通过将它附加到客户端上下文传递回来,但是,这不起作用for,因为onReceiveNotification()在JS调试器中始终未定义?
我错过了什么
notificationhub.cs
[HubName("notificationHub")]
public class NotificationHub : Hub
{
public override System.Threading.Tasks.Task OnConnected()
{
return base.OnConnected();
}
public override System.Threading.Tasks.Task OnDisconnected(bool stopCalled)
{
return base.OnDisconnected(stopCalled);
}
public override System.Threading.Tasks.Task OnReconnected()
{
return base.OnReconnected();
}
[HubMethodName("sendNotifications")]
public void SendNotifications(string message)
{
Clients.All.onRecieveNotification(string.Format("{0} {1}", message, DateTime.Now.ToString()));
}
}
message.html页面
<div>
<input type="text" id="messageinput" />
<button id="notifybutton">Send Message</button>
</div>
<script src="Scripts/jquery-2.1.4.min.js"></script>
<script src="Scripts/jquery.signalR-2.2.0.min.js"></script>
<script src="signalr/hubs"></script>
<script type="text/javascript">
jQuery(document).ready(function ($)
{
var $hub = $.connection.notificationHub;
$.connection.hub.start();
$(document).on("click", "#notifybutton", {}, function (e)
{
e.preventDefault();
var $message = $("#messageinput").val();
$hub.server.sendNotifications($message);
});
});
</script>
display.html
<div>
<ul id="messages"></ul>
</div>
<script src="Scripts/jquery-2.1.4.min.js"></script>
<script src="Scripts/jquery.signalR-2.2.0.min.js"></script>
<script src="signalr/hubs"></script>
<script type="text/javascript">
jQuery(document).ready(function ($)
{
var $hub = $.connection.notificationHub;
$hub.onRecieveNotification = function (message)
{
$("#message").append($("<li></li>", { text: message }));
}
$.connection.hub.start();
});
</script>
答案 0 :(得分:1)
您似乎错过了client
:
$hub.client.onRecieveNotification = function (message)
{
$("#message").append($("<li></li>", { text: message }));
}
