WCF不處理二進制格式的MSMQ消息

Question

我有一個WCF Windows服務，可以檢索MSMQ消息。 似乎未調用SubmitPurchaseOrderInMessage，在隊列中也看不到任何消息。 代碼如下所示。

WCF類：

public class OrderProcessorService : IOrderProcessor
{
    [OperationBehavior(TransactionScopeRequired = true, TransactionAutoComplete = true)]
    [ServiceKnownType(typeof(MyOrder))]
    public void SubmitPurchaseOrderInMessage(MsmqMessage<MyOrder> ordermsg)
    {
        MyOrder po = (MyOrder)ordermsg.Body;
        Console.WriteLine("Processing id:{0}, name:{1} ", po.ID, po.Name);
    }

    public static void Main()
    {
        //init queue
        if (!MessageQueue.Exists(Constants.QUEUE_PATH)) MessageQueue.Create(Constants.QUEUE_PATH, true);

        //init wcf host via code
        Uri baseUri = new Uri("http://localhost:7878/msmqsvc");
        using (ServiceHost host = new ServiceHost(typeof(OrderProcessorService),baseUri))
        {
            //add metadata behavior
            ServiceMetadataBehavior smb = new ServiceMetadataBehavior(){ HttpGetEnabled=true};
            host.Description.Behaviors.Add(smb);

            //add service endpoint
            MsmqIntegrationBinding binding = new MsmqIntegrationBinding(MsmqIntegrationSecurityMode.None);
            binding.SerializationFormat = MsmqMessageSerializationFormat.Binary;
            host.AddServiceEndpoint(typeof(ClassLib.IOrderProcessor), binding, "msmq.formatname:DIRECT=OS:" + Constants.QUEUE_PATH);

            host.Open();

            // The service can now be accessed.
            Console.WriteLine("The service is ready.");
            Console.WriteLine("Press <ENTER> to terminate service.");
            Console.ReadLine();
            host.Close();
        }
    }
}

接口合同：

[ServiceContract(Namespace = "http://Microsoft.ServiceModel.Samples")]
[ServiceKnownType(typeof(MyOrder))]
public interface IOrderProcessor
{
    [OperationContract(IsOneWay = true, Action = "*")]
    void SubmitPurchaseOrderInMessage(MsmqMessage<MyOrder> msg);
}

數組Parameters可以是客戶端可以傳遞的任何動態可序列化類型。 我認為問題在於此參數。 如果我在客戶端中刪除了此參數和可序列化的屬性以及binding.SerializationFormat，那么eveything可以正常工作。

可序列化的類：

[DataContract(Namespace = "http://Microsoft.ServiceModel.Samples")]
[Serializable]
public class MyOrder
{
    [DataMember]
    public string ID;

    [DataMember]
    public string Name;

    [DataMember]
    public object[] Parameters;
}

[Serializable]
public class Transaction
{
    public int Amount { get; set; }
}

客戶：

 class Program
 {
    static void Main(string[] args)
    {
        try
        {
            Run();
        }
        catch (Exception ex)
        {
            Console.WriteLine(ex.ToString());
        }
    }

    static void Run()
    {
        MsmqIntegrationBinding binding = new MsmqIntegrationBinding();
        binding.Security.Mode = MsmqIntegrationSecurityMode.None;
        binding.Security.Transport.MsmqAuthenticationMode = MsmqAuthenticationMode.None;
        binding.Security.Transport.MsmqProtectionLevel = System.Net.Security.ProtectionLevel.None;
        binding.SerializationFormat = MsmqMessageSerializationFormat.Binary;
        EndpointAddress address = new EndpointAddress("msmq.formatname:DIRECT=OS:" + Constants.QUEUE_PATH);

        ChannelFactory<ClassLib.IOrderProcessor> channelFactory = new ChannelFactory<ClassLib.IOrderProcessor>(binding, address);

        try
        {
            ClassLib.IOrderProcessor channel = channelFactory.CreateChannel();

            MyOrder order = new MyOrder();
            order.ID = DateTime.Now.Ticks.ToString();
            order.Name = "Order_" + order.ID;
            order.Parameters = new object[] { new Transaction { Amount = 108 }, new Transaction { Amount = 100 } };
            MsmqMessage<MyOrder> ordermsg = new MsmqMessage<MyOrder>(order);

            using (TransactionScope scope = new TransactionScope(TransactionScopeOption.Required))
            {
                channel.SubmitPurchaseOrderInMessage(ordermsg);
                scope.Complete();
            }

            Console.WriteLine("Order has been submitted:{0}", ordermsg);
        }
        catch(Exception ex)
        {

        }
        finally
        {
            channelFactory.Close();
        }
    }
}

這里有一些要檢查的東西：

1. 在臨時出站隊列客戶端中不檢查任何消息。 如果此隊列中有消息，則表明該消息無法在網絡上傳輸。 因為您的隊列是事務性的，這可能意味着MSDTC配置 （鏈接也支持2012）。

2. 在服務端檢查事務性死信隊列中是否沒有消息。 如果存在，則表示將消息傳遞到服務隊列時出現問題。 可能是權限問題。 服務帳戶在其隊列上需要“ 接收消息”和“ 查看消息 ”，客戶端帳戶在目標隊列上需要“ 發送消息” ，“ 獲取權限 ”和“ 獲取屬性 ”。

3. 在Windows事件日志中啟用msmq日志記錄 。 這會將所有與MSMQ相關的活動記錄在框中。 服務端成功傳輸后，您應該在日志中看到2個事件： 消息來自網絡 ，並且ID為ID的消息進入隊列 。
