使用 XMS 向 IBM WebSphere MQ 发送和接收 XML 格式的文本

Question

我们有 IBM WebSphere MQ 7.5。我们已经设置了队列管理器和队列。我们希望使用 XMS for .net 客户端应用程序从队列中读取和写入 XML 格式的文本。我尝试了下面的代码，但我不知道如何读取该数据。

代码：

try
         {
                var factoryfactory = XMSFactoryFactory.GetInstance(XMSC.CT_WMQ);
                var connectionfactory = factoryfactory.CreateConnectionFactory();
                connectionfactory.SetStringProperty(XMSC.WMQ_QUEUE_MANAGER, queueManager);
                connectionfactory.SetStringProperty(XMSC.WMQ_HOST_NAME, hostIP);
                connectionfactory.SetIntProperty(XMSC.WMQ_PORT, port);
                connectionfactory.SetStringProperty(XMSC.WMQ_CHANNEL, channel);
                connectionfactory.SetIntProperty(XMSC.WMQ_BROKER_VERSION, XMSC.WMQ_BROKER_V2);
                connectionfactory.SetIntProperty(XMSC.WMQ_CONNECTION_MODE, XMSC.WMQ_CM_CLIENT_UNMANAGED);
                using (IConnection conn = connectionfactory.CreateConnection())
                {
                    using (ISession session = conn.CreateSession(false, AcknowledgeMode.AutoAcknowledge))
                    {
                        using (IDestination dest = session.CreateQueue(string.Format("queue://{0}", queueName))) // Create a queue
                        {
                            using (IMessageConsumer consumer = session.CreateConsumer(dest))
                            {
                                conn.Start();
                                IMessage recvMsg = null;
                                recvMsg = consumer.Receive();
                                if (recvMsg != null)
                                    return recvMsg;

                            }
                        }
                    }
                }
            }
            catch(XMSException ex)
            {

            }

recvMsg 正在 JMS 中返回数据。任何工作代码来读取字符串/XML 的数据？

您的应用程序正在以jms_bytes 类型的消息形式获取消息。由于 XML 基本上是文本，您可以使用 ITextMessage 消息类型来发送和接收 XML 有效负载。更改您的生产者应用程序以发送ITextMessage 类型的消息，并更改您的应用程序以接收相同的消息类型。示例 sn-p 在这里。

制作人：

   IMessageProducer producer;
   ITextMessage textMessage;

   // create session, producer
   ....

   textMessage = sessionWMQ.CreateTextMessage();
   textMessage.Text = XmlPayload;
   producer.Send(textMessage);

消费者：

IMessageConsumer consumer;
ITextMessage textMessage;

// create session and consumer

....
// Receive text message
textMessage = (ITextMessage)consumer.Receive(3000); // Wait for 3 seconds to receive message
String XmlPayload = textMessage.Text;
