Question

我试图通过定义connectionID将一些对象从信号器中心传递到客户端但是这似乎不起作用。因为我收到错误Microsoft.AspNet.SignalR.Hubs.IHubCallerConnectionContext<object>' does not contain a definition for 'Client'

这就是我调用代码的方式：

Clients.Client(initiatedBrowserId).mibChoice(connectionId, queriesDictionary, deviceID);

这是所要求的整个方法：

public void DetectDevice(dynamic message)
    {
        var connectionId = Context.ConnectionId;
        //now we get the connectionID from the table.
        var connectionObj = ConnectionTable[connectionId];

        //we now check whether this is a pathfinder or browser client
        if (connectionObj.clientType == "pathfinder")
        {
            /*The pathfinder initiated the request and so this means the message should be forwarded to the browser client
             that requested this resource*/

            var deviceDiscoveredNotification = JsonConvert.DeserializeObject<Dictionary<string, string>>(message);
            var initiatedBrowserId = deviceDiscoveredNotification["browserConnectionID"];
            //message should contain browser client connection id
            if (deviceDiscoveredNotification["data"] == "FOUND")
            {
                //We can base these around device type

                //snmp
                var mibNames = db.OIDs.Select(oid => oid.Mibname).Distinct().ToList();
                //wmi
                var wmiQueries = db.WmiQueries.Select(wmi => wmi.Query).Where(wmi => !wmi.Contains("*")).Distinct().ToList();
                var wmiList = new List<ScheduledMonitoring>();

                var mibList = mibNames.Select(mib => new ScheduledMonitoring(mib, 60)).ToList();

                mibList.AddRange(wmiQueries.Select(wmi => new ScheduledMonitoring(wmi, 60)));

                //Let's construct a data structure that is easy to parse and traverse
                var queriesDictionary = new Dictionary<string, List<ScheduledMonitoring>>();
                queriesDictionary.Add("snmp", mibList);
                queriesDictionary.Add("wmi", wmiList);

                // pass the pathfinderID along with the mibnames, the pathfinder connectionID
                // needs to also be passed back to the MonitorFeatures  method so we know specifically
                var deviceID = deviceDiscoveredNotification["deviceID"];

                try
                {
                    Clients.Client(initiatedBrowserId).mibChoice(connectionId, queriesDictionary, deviceID);
                }
                catch (Exception e)
                {
                    throw e;
                }

            }
}

我知道存在这种连接，因为我可以在我的字典中看到它维护什么connectionID映射到谁，如果他们要断开它会将它们从字典中删除

signalr hub不包含Client的定义
