问题描述

所以即时通讯尝试连接到C＃中的服务，我无法控制此服务，并且无法在那里更改任何内容，也没有任何文档可帮助:(

所以我想做的就是将此JavaScript SignalR客户端更改为.net（但不是全部） 

    $(document).ready(function () {

        //URL of the queues api
        var queueApi = "/CCMWa/api/v1/queues/";

        //SignalR connection
        $.connection.hub.logging = true;
        var myHub = $.connection.queueStatistics;

        //Wire event handlers
        myHub.client.onQueueNowDataUpdate = function (data) {
            //alert(data);
            var data = JSON.stringify(data);
            $('#messages').append('<li>Server: Received onQueueNowDataUpdate</li>');
            $('#getNowResults').text(data);
        };

        //Wire event handlers
        myHub.client.onQueueConversationUpdate = function (data) {
            //alert(data);
            var data = JSON.stringify(data);
            $('#messages').append('<li>Server: Received onQueueConversationUpdate</li>');
            $('#getConversationResults').text(data);
        };

        //Wire event handlers
        myHub.client.connected = function () {
            $('#messages').append('<li>Server: Says we are Connected</li>');                
        };

        //Wire event handlers
        myHub.client.reconnected = function () {
            $('#messages').append('<li>Server: Says we are Reconnected</li>');
        };

        //Start
        $.connection.hub.start()
                        .done(function () {
                            logMessage("Client: Connection Started");
                            //myHub.server.joinFoo()
                            //     .done(function () {
                            //         logMessage("Client: Sent Join to Server");
                            //     })
                        })
                        .fail(function () {
                            logMessage("Client: Could not connect to server");
                        });

        $("#startNow").click(function () {
            var id = $("#queueNowId").val();

            myHub.server.startQueueStateMonitor(id)
               .done(function () {
                   $('#messages').append('<li>Client: addMonitor for ' + id + '</li>');
               })
               .fail(function () {
                   $('#messages').append('<li>Client: failed to send addMonitor</li>');
               });

        });

        function logMessage(message)
        {
            $('#messages').append(message);
        }

        $("#stopNow").click(function () {
            var id = $("#queueNowId").val();

            myHub.server.stopQueueStateMonitor(id)
               .done(function () {
                   $('#messages').append('<li>Client: removeMonitor for ' + id + '</li>');
               })
               .fail(function () {
                   $('#messages').append('<li>Client: failed to send removeMonitor</li>');
               });
        });

        $("#getAll").click(function () {
            var uri = queueApi;
            //alert(uri);
            $.get(uri,
                function (items) {
                    data = JSON.stringify(items);
                    $("#getAllResults").text(data);
                });                
        });

        $("#getDetails").click(function () {
            var id = $("#queueDetailsId").val();
            var uri = queueApi + id;
            //alert(uri);
            $.get(uri,

                    data = JSON.stringify(items);
                    $('#getDetailsResults').text(data);
                });
        });           

        $("#getNow").click(function () {
            var id = $("#queueNowId").val();
            var uri = queueApi + id + "/now";
            //alert(uri);
            $.get(uri,
                function (items) {
                    data = JSON.stringify(items);
                    $('#getNowResults').text(data);
                });
        });


        $("#startConversationMonitor").click(function () {
            var id = $("#queueConversationsId").val();

            myHub.server.startQueueConversationMonitor(id)
               .done(function () {
                   $('#messages').append('<li>Client: addMonitor for ' + id + '</li>');
               })
               .fail(function () {
                   $('#messages').append('<li>Client: failed to send addMonitor</li>');
               });
        });


        $("#stopConversationMonitor").click(function () {

        $("#getConversations").click(function () {

                    $('#getConversationResults').text(data);
                });
        });
    });

这是我目前在C＃中所拥有的

        connection.TraceLevel = TraceLevels.All;
        connection.TraceWriter = Console.Out;

        //Make proxy to hub based on hub name on server
        var myHub = connection.CreateHubProxy("queueStatistics");

        //Start connection


        connection.Start().ContinueWith(task => {
            if (task.IsFaulted) {
                Console.WriteLine("There was an error opening the connection:{0}",

                Console.WriteLine("Connected");
            }

        }).Wait();

        myHub.Invoke<string>("startQueueStateMonitor", "445cb4e7-88a7-47d4-bb13-e8b40854f4a5").ContinueWith(task =>

        Console.Read();
        connection.Stop();
    }
    }
}

这是它的输出

如果不自己运行，则不是100％，但是：

我认为问题是您的调试行： 

myHub.On<string>("onQueueNowDataUpdate", data => { Console.WriteLine(data); });

该行将传入的消息视为字符串，除了数据不是字符串，因为它是序列化的对象。

即数据中的内容是在跟踪中看起来如下的部分（其中M表示我认为的消息正文）： 

 "M": [
            {
                "H": "queueStatistics",
                "M": "onQueueNowDataUpdate",
                "A": [
                    {
                        "configData": {

Json反序列化器想要类似 

 "M": "Foobar"

确实，您需要一个与传入消息匹配的类声明（意识到，这可能是您接下来要编写的内容）。

更新类生成：

从Json生成类的最简单的想法是让其他人替您完成。 如果将消息（忽略"M:["部分） 粘贴到json2csharp.com中 ： 

            {
                "H": "queueStatistics",
                "M": "onQueueNowDataUpdate",
                "A": [
                    {
                        "configData": {
                            "Id": "445cb 4e7-88a7-47d4-bb13-e8b40854f4a5",

                            "MediaType": 0,
                            "MediaServer": null,
                            "MediaServerId": "00000000-0000-0000-0000-000000000000",
                            "NowStatisticsUrl": null,
                            "StatisticsHubName": " queueStatistics",
                            "Links": [

                            ],
                            "Url": null
                        },
                        "Status": "ACD",
                        "LongestWaiting": 0.0,
                        "Acd": 0,
                        "NonAcd": 0,
                        "Out": 0,
                        "Unavailable": 1,
                        "Offered": 3,
                        "Handled": 3,
                        "Abandoned": 0,
                        "Interflow": 0,
                        "Requeue": 0,
                        "ServiceLevel": 100,
                        "AgentsIdle": 2,
                        "ItemsWaiting": 0,
                        "QueueOpen": false,
                        "AgentsLoggedIn": 0,
                        "AgentsAvailable": 2,
                        "EstimatedWaitTime": 0.0,
                        "AverageHandlingTime": 0,
                        "DetailsUrl": null
                    }
                ]
            }

你得到： 

public class ConfigData
{
    public string Id { get; set; }
    public string Name { get; set; }
    public string Reporting { get; set; }
    public int MediaType { get; set; }

    public string MediaServerId { get; set; }
    public object NowStatisticsUrl { get; set; }
    public string StatisticsHubName { get; set; }
    public List<object> Links { get; set; }
    public object Url { get; set; }
}

public class A
{
    public ConfigData configData { get; set; }
    public string Status { get; set; }
    public double LongestWaiting { get; set; }
    public int Acd { get; set; }
    public int NonAcd { get; set; }
    public int Out { get; set; }
    public int Unavailable { get; set; }
    public int Offered { get; set; }
    public int Handled { get; set; }

    public double EstimatedWaitTime { get; set; }

}

public class RootObject
{
    public string H { get; set; }
    public string M { get; set; }
    public List<A> A { get; set; }
}

您应该将RootObject的名称更改为对您更有意义的名称。 还要注意，很明显，这只知道原始Json中的属性，因此您应该使用将要接收的消息的最复杂版本来做到这一点，以便可以避免错过任何内容。

然后，您可以使用来获取类实例（与使用JS版本时差不多）： 

myHub.On<RootObject>("onQueueNowDataUpdate", data => { <<Do something with RootData instance here>> });
