SignalR集线器上下文不返回消息。 [英] SignalR hub context not returning message.

问题描述

嘿伙计们，我只是想知道是否有人可以帮助我。我有一个Windows服务，它在我的Web应用程序中调用hub类。我的问题是，当我创建集线器上下文并调用显示消息时，消息不会显示。初始连接很好，我可以从提琴手看到集线器已连接。



服务代码

  var  context = GlobalHost.ConnectionManager.GetHubContext< ClientNotificationsHub>（）; 
 context.Clients.All.DisplayMessage（）; 

客户代码

 $（function（）{
 
 var hub = $ .connection.dbHub; 
 
 hub.client.displayMessage = function（）{
 
 alert（成功）; 
}; 
 
 $ .connection.hub.start（）。done（function（）{
 var userId =''< ％=会话（iUserId）％>''; 
 var connection =''<％=会话（sDBConnection）％>''; 
 hub.server.setConnection（userId ，连接）; 
}）; 
}）; 
 

该服务也在同一个解决方案中，我将其作为控制台应用程序运行以进行测试。任何帮助都是非常吝啬的人。

解决方案

（function（）{

var hub =

< blockquote> .connection.dbHub;

hub.client.displayMessage = function（）{

alert（Success）;
};

.connection.hub.start（）。done（function（）{
var userId =''<％= Session（iUserId）％>'';
var connection =''<％= Session（sDBConnection）％>'';
hub.server.setConnection（userId，connection）;
}）;
}） ;

Hey guys, I''m just wondering if anyone can help me. I have a windows service which calls the hub class in my web application. My problem is that when I create the hub context and call the display message the messages don''t get displayed. The initial connection is fine and I can see from fiddler that the hub is connected.

Service code

 var context = GlobalHost.ConnectionManager.GetHubContext<ClientNotificationsHub>();
context.Clients.All.DisplayMessage();

Client code

$(function () {

           var hub = $.connection.dbHub;

           hub.client.displayMessage = function () {

               alert("Success");
           };

           $.connection.hub.start().done(function () {
               var userId = ''<%=Session("iUserId")%>'';
               var connection = ''<%=Session("sDBConnection")%>'';
               hub.server.setConnection(userId, connection);
           });
       });

The service is also in the same solution and I have it running as a console app for testing purposes. Any help is very much apreciated guys.
