Javascript 信号器2.2客户端未接收任何消息

我有一个在控制台应用程序上下文中运行的自托管Signal应用程序。我通过使用包装器类连接到其中的集线器，以避免必须引用ASP.NET项目中的signar.Core程序集。因此，它是我的应用程序中的另一个C#类，负责向连接的客户端广播消息

我可以直接从Javascript调用

PlanHub

方法（

Register

和

Unregister

），这些断点会被命中。但是，当我从中心之外的类调用客户机方法时（即使我使用

Clients.All

来消除组注册问题），客户机永远不会收到消息。我做错了什么

运行此代码时，我可以验证

Clients.All.updateStatus（planId，message）成功命中代码，但客户端控制台上没有记录任何内容。

以下是相关代码：

PlanHub.cs

public class PlanHub : Hub
{
    private const string GroupPrefix = "PlanGroup_";

    public void Register(int companyId)
    {
        Groups.Add(Context.ConnectionId, $"{GroupPrefix}{companyId}");
    }

    public void Unregister(int companyId)
    {
        Groups.Remove(Context.ConnectionId, $"{GroupPrefix}{companyId}");
    }
}

public class PlanPublisher
{
    private readonly static Lazy<PlanPublisher> _instance = new Lazy<PlanPublisher>(() => 
        new PlanPublisher(GlobalHost.ConnectionManager.GetHubContext<PlanHub>().Clients));
    private IHubConnectionContext<dynamic> Clients { get; set; }

    private PlanPublisher(IHubConnectionContext<dynamic> clients)
    {
        Clients = clients;
    }

    public static PlanPublisher Instance => _instance.Value;

    public void UpdateStatus(int planId, string message)
    {
        //This code gets hit and no exceptions are thrown, but the clients
        //never receive the message. Using Clients.All instead of my 
        //Groups for testing -- still doesn't work
        Clients.All.updateStatus(planId, message);
    }
}

PlanPublisher.Instance.UpdateStatus(plan.Id, $"Publishing started for {plan.Name}...");

PlanPublisher.cs

public class PlanHub : Hub
{
    private const string GroupPrefix = "PlanGroup_";

    public void Register(int companyId)
    {
        Groups.Add(Context.ConnectionId, $"{GroupPrefix}{companyId}");
    }

    public void Unregister(int companyId)
    {
        Groups.Remove(Context.ConnectionId, $"{GroupPrefix}{companyId}");
    }
}

public class PlanPublisher
{
    private readonly static Lazy<PlanPublisher> _instance = new Lazy<PlanPublisher>(() => 
        new PlanPublisher(GlobalHost.ConnectionManager.GetHubContext<PlanHub>().Clients));
    private IHubConnectionContext<dynamic> Clients { get; set; }

    private PlanPublisher(IHubConnectionContext<dynamic> clients)
    {
        Clients = clients;
    }

    public static PlanPublisher Instance => _instance.Value;

    public void UpdateStatus(int planId, string message)
    {
        //This code gets hit and no exceptions are thrown, but the clients
        //never receive the message. Using Clients.All instead of my 
        //Groups for testing -- still doesn't work
        Clients.All.updateStatus(planId, message);
    }
}

PlanPublisher.Instance.UpdateStatus(plan.Id, $"Publishing started for {plan.Name}...");

它成功注册，但从未收到任何数据。
Clients.All.updateStatus（planId，message）断点被多次命中，但控制台从未收到任何其他日志记录数据

编辑：有人建议我研究一下自定义依赖项解析程序是否在使用中。这里发布的代码位于它自己的项目中，除了您在这里看到的内容之外，几乎没有其他内容。调用
PlanPublisher.UpdateStatus（）
的代码确实有一个自定义依赖项解析程序，但这并不重要，因为它在自己的程序集中是独立的
PlanPublisher.cs
和
PlanHub.cs
包含在一个非常简单的项目中，该项目只引用了signer.Core和signer.SelfHost。
尝试以下方法：

public void UpdateStatus(int planId, string message)
{
    var clients = GlobalHost.ConnectionManager.GetHubContext<PlanHub>().Clients;
    clients.All.updateStatus(planId, message);
}

public void UpdateStatus（int-planId，字符串消息）
{
var clients=GlobalHost.ConnectionManager.GetHubContext（）.clients；
clients.All.updateStatus（planId，message）；
}

我认为问题在于PlanPublisher是在创建集线器上下文（和客户端）之前初始化的。
我试图简化您的示例（使用SignalR 2.2.0）

枢纽等级：

public class PlanHub : Hub
{
    private const string GroupPrefix = "PlanGroup_";

    // hubcontext
    private static IHubContext hubContext = GlobalHost.ConnectionManager.GetHubContext <PlanHub> ();

    public void Register(int companyId)
    {
        Groups.Add(Context.ConnectionId, $"{GroupPrefix}{companyId}");
    }

    public void Unregister(int companyId)
    {
        Groups.Remove(Context.ConnectionId, $"{GroupPrefix}{companyId}");
    }

    // static method using hub context
    public static void Static_UpdateStatus(int planId, string message)
    {
        hubContext.Clients.All.updateStatus(planId, message);
    }
}

谢谢你的建议。只是尝试了一下，但行为还是一样的。你能发布.js控制台调试吗<代码>$.connection.hub.logging=true您需要提供再现问题的最小示例。我只是试着在服务器端和客户端都使用您提供的代码运行，结果运行得很好，没有任何问题。@Scott，您设法解决了吗？因为我面临着同样的问题。有趣的是，如果我试着为团队发表文章，它是有效的，但不是所有人都有效。另一方面，当我创建一个单独的项目来尝试这个功能时，一切都很好。
