编辑:请查看此帖子的底部是否有更新。
我的SignalR实现在我的本地系统上完美运行。但是当我将它部署到我的服务器时,它似乎无法工作。它是一个MVC项目。
我的signalR jQuery如下:
var clientHub = $.connection.gamehub;
$(function () {
var signalRHubInitialized = false;
var image = $("#Ico");
var count = 0;
initializeSignalRHubStore();
function initializeSignalRHubStore() {
if (signalRHubInitialized)
return;
try {
clientHub.client.broadcastMessage = function (message) {
if (message === "Refresh")
reloadIndexPartial();
};
$.connection.hub.start().done(function () {
clientHub.server.initialize($("#NotifierEntity").val());
signalRHubInitialized = true;
});
} catch (err) {
signalRHubInitialized = false;
}
};
function reloadIndexPartial() {
//$.post('@(Url.Action("LivePartial", "Scrim", null, Request.Url.Scheme))')
var id = $("#SeriesDetail_Id").val();
$.post('/Scrim/LivePartial/' + id)
.done(function (response) {
try {
count = count + 1;
var favicon = new Favico({
animation: 'pop',
image: image
});
favicon.badge(count);
}
catch (exception) {
}
$("#summary-wrapper").html("");
$("#summary-wrapper").html(response);
if (!signalRHubInitialized)
initializeSignalRHubStore();
});
};
});
我下载了Fiddler,看看发生了什么:

我已将此添加到我的网络配置中:
<modules runAllManagedModulesForAllRequests="true"></modules>
查看所有响应,似乎一切正常,但是当新条目添加到数据库时,页面Im on不会更新。
在我的本地开发系统上,我的项目是使用IIS设置的,它可以完美运行。
请有人指出我正确的方向。
编辑:我现在已经在服务器上工作了。但似乎它在部署几个小时之后才能正常工作。然后,它似乎停止工作。所以我必须假设信号器连接正在某个阶段处理,现在恢复了?这是我的RegisterServices类:
private static IContainer RegisterServices(ContainerBuilder builder)
{
builder.RegisterControllers(Assembly.GetExecutingAssembly());
builder.RegisterApiControllers(Assembly.GetExecutingAssembly());
builder.RegisterType<ContextEntities>()
.As<DbContext>()
.InstancePerRequest();
builder.RegisterType<DbFactory>()
.As<IDbFactory>()
.InstancePerRequest();
builder.RegisterType<UnitOfWork>()
.As<IUnitOfWork>()
.InstancePerRequest();
// Services
builder.RegisterType<MembershipService>()
.As<IMembershipService>()
.InstancePerRequest();
builder.RegisterType<CacheService>()
.As<ICacheService>()
.InstancePerRequest();
builder.RegisterType<GameHub>().ExternallyOwned();
Container = builder.Build();
return Container;
}
以下是使用信号器的页面:http://halodatahive.com/Scrim/Live/2845
部署后几个小时后,我似乎失去了对信号器连接的引用。
编辑:如果我回收我的APP POOL,带有signalR的页面将重新开始工作。
答案 0 :(得分:6)
这是我最终用来解决问题的方法。似乎在大约1小时之后它就会断开连接。我几个小时前就把这段代码放了,但它似乎仍然有效。感谢@Noren早些时候在聊天方面的帮助!
编辑:不幸的是,这似乎没有解决问题。
$.connection.hub.disconnected(function() {
setTimeout(function() {
$.connection.hub.start();
}, 5000); // Restart connection after 5 seconds.
});
编辑:我想我会更新一下如何运作。我没有使用SqlDependency
来触发SignalR,而是在调度Clients.All.broadcastMessage("Refresh");
时调度的任务上调用了_unitOfWork.Commit()
。
某些事情导致SqlDependency停止工作,让它再次获取它的唯一方法是回收应用程序池。
答案 1 :(得分:2)
我以前见过这样的东西。在我的情况下,由于IIS正在关闭应用程序,因此丢失了RabbitMQ事件。
您的应用程序是否经常被击中? IIS倾向于降低它认为不需要的应用程序以节省资源。这可能就是为什么它只能在几个小时后停止工作,你可以回收再把它恢复原状。

NotificationsHubs.cs中的首先在根
中添加集线器文件夹和NotificationsHubs.cs
[HubName("NotificationsHubs")]
public class NotificationsHubs : Hub
{
public static Thread NotificationsThread;
public void Send(string token, string UserAgent, string IP)
{
var serverVars = Context.Request.GetHttpContext().Request.ServerVariables;
string SignalRIp = serverVars["REMOTE_ADDR"];
string T = Context.Request.Headers["User-Agent"].ToLower();
if ((T == cryptClass.crypt.Decrypt(UserAgent)) && (SignalRIp == cryptClass.crypt.Decrypt(IP)))
{
var connection = SignalRConnections.Connections.SingleOrDefault(c => c.Token == Guid.Parse(token));
if (connection != null)
{
connection.Context = this.Context;
}
if (NotificationsThread == null || !NotificationsThread.IsAlive)
{
NotificationsThread = new Thread(new ThreadStart(NotificationsCheck));
NotificationsThread.Start();
}
}
NotificationsCheck
是自定义功能
NotificationController
中的
public ActionResult Notifications()
{
NotificationsModule.messageBL = _messageBL;
long UserID = GetCurrentUser();
Notification _Notification = new Notification();
_Notification.GetToken = SignalRConnections.GetToken(UserID);
_Notification.UserAgent = cryptClass.crypt.Encrypt(Request.UserAgent.ToLower());
_Notification.IP = cryptClass.crypt.Encrypt(Request.UserHostAddress);
return View(_Notification);
}
在Notifications.cshtml
视图中
添加此JS文件
<script src="~/Scripts/jquery.signalR-2.2.1.js")"></script>
<script src="~/signalr/hubs"></script>
$(function () {
// Reference the auto-generated proxy for the hub.
var chat = $.connection.NotificationsHubs;
// Create a function that the hub can call back to display messages.
chat.client.addNewMessageToPage = function (Title, Body, Icon) {
// Add the message to the page.
notifyMe(Title, Body, Icon);
};
$.connection.hub.start().done(function () {
chat.server.send('@Model.GetToken', '@Model.UserAgent', '@Model.IP');
$('#sendmessage').click(function () {
// Call the Send method on the hub.
chat.server.send();
});
});
});
notifyMe(Title, Body, Icon);
是jquery自定义函数
