Question

我使用signalR。组功能无法正常工作。

这是我的中心：

public class BasketHub : Hub
{
    public void Login(int companyId)
    {
        string groupName = "company" + companyId;

        IHubContext context = GlobalHost.ConnectionManager.GetHubContext<BasketHub>();

        context.Groups.Add(Context.ConnectionId, groupName);
    }

    public void Logout(int companyId)
    {
        string groupName = "company" + companyId;

        IHubContext context = GlobalHost.ConnectionManager.GetHubContext<BasketHub>();

        context.Groups.Remove(Context.ConnectionId, groupName);
    }
}

这是使用服务器端：

  public void OrderConfirm(OrderConfirmModel orderConfirmModel)
  {
        IHubContext context = GlobalHost.ConnectionManager.GetHubContext<BasketHub>();

        var groupName = "company" + orderConfirmModel.CompanyId;

        context.Clients.Group(groupName).orderConfirm(orderConfirmModel.DidNewOrder);

        context.Clients.Group(groupName).newOrderCount(orderConfirmModel.DidNewOrder);

        context.Clients.Group(groupName).didGetNotification(orderConfirmModel.BasketId);
  }

这是客户：

       $(function () {
        var basketHub = $.connection.basketHub;

        basketHub.client.newOrderCount = function (isNewOrder) {
            // some code
        }

        basketHub.client.didGetNotification = function (basketId) {
            // some code
        }

        basketHub.client.orderConfirm = function (isNewOrder) {
             // some code
        }

        $.connection.hub.start();
    });

此处是群组添加和删除客户端：

    $(function () {
    var basketHub = $.connection.basketHub;

    $.connection.hub.start().done(function () {
        basketHub.server.login($scope.Company.Id);

        $('#logoutBtn').click(function () {
            basketHub.server.logout($scope.Company.Id);
        });
    });

    $(window).bind('beforeunload', function (e) {
        basketHub.server.logout($scope.Company.Id);
    });
});

我在BasketHub的上下文中创建了该组。但是，当我尝试使用该组时，我不会达到它。并且客户端没有触发通知。

我可以像下面这样使用它：

context.Clients.All.orderConfirm(orderConfirmModel.DidNewOrder);
context.Clients.All.newOrderCount(orderConfirmModel.DidNewOrder);
context.Clients.All.didGetNotification(orderConfirmModel.BasketId);

最诚挚的问候。

我找到了解决方案。编写一个角度控制器，每个页面加载运行init（如layout-controller）。我在这里定义我的集线器并发出功能。 SingnalR小组工作正常。

    $(function () {
    var basketHub = $.connection.basketHub;

    basketHub.client.orderConfirm = function (isNewOrder) {
        $rootScope.$emit("basketOrderConfirm", isNewOrder);
    }

    basketHub.client.newOrderCount = function (isNewOrder) {
        $rootScope.$emit("newOrderCount", isNewOrder);
    }

    basketHub.client.didGetNotification = function (basketId) {
        $rootScope.$emit("didGetNotification", basketId);
    }

    $.connection.hub.start().done(function () {
        basketHub.server.login($scope.Company.Id);

        $('#logoutBtn').click(function () {
            basketHub.server.logout($scope.Company.Id);
        });
    });

    $(window).bind('beforeunload', function (e) {
        basketHub.server.logout($scope.Company.Id);
    });
});
