c# - SignalR - 在部署到服务器时工作，但在几个小时后停止(MVC)

Question

编辑:查看这篇文章的底部以获取更新。

我的 SignalR 实现在我的本地系统上运行完美。但是当我将它部署到我的服务器时，它似乎不起作用。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>

查看所有回复，似乎一切正常，但当新条目添加到数据库时，我所在的页面没有更新。

在我的本地开发系统上，我的项目是使用 IIS 设置的，它运行完美。

谁能指出我正确的方向。

编辑:我现在已经在服务器上运行了。但是似乎部署几个小时后它就可以工作了。然后在那之后它似乎停止工作。所以我必须假设信号器连接在某个阶段被处理，现在正在恢复？

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;
}

这是一个使用信号器的页面: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:如果我回收我的应用程序池，带有 signalR 的页面将再次开始工作。

Answer 1

这就是我最终用来解决问题的方法。似乎在大约 1 小时后它以某种方式断开连接。我在几个小时前输入了这段代码，它似乎仍然有效。感谢@Noren 之前在聊天中提供的所有帮助!

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:我想我会更新我是如何让它工作的。我没有使用 SqlDependency 来触发 SignalR，而是调用 Clients.All.broadcastMessage("Refresh"); 我在服务器上运行的计划任务 调用了 _unitOfWork.Commit()。

某些原因导致 SqlDependency 停止工作，让它再次恢复的唯一方法是回收应用程序池。
