Question

我正在开发一个项目，我们希望通过Azure Service Bus（主题）发送消息。在这个例子中，我设置了一个C＃Console应用程序和一个Java应用程序，用于在它们之间发送和接收消息。

从C＃发送消息时，我在Java中收到一个格式奇怪的字符串，其中包含“schema.microsoft.com/2003/10/serialisation”。更改邮件内容类型没有任何区别。

当从Java向C＃发送数据时，我得到一个例外。

发送/接收数据 - C＃

private static void SendMessages()
    {
        topicClient = TopicClient.Create(TopicName);

        List<BrokeredMessage> messageList = new List<BrokeredMessage>();
        messageList.Add(CreateSampleMessage("1", "Test"));

        Console.WriteLine("\nSending messages to topic...");

        foreach (BrokeredMessage message in messageList)
        {
            while (true)
            {
                try
                {
                    topicClient.Send(message);
                }
                catch (MessagingException e)
                {
                    if (!e.IsTransient)
                    {
                        Console.WriteLine(e.Message);
                        throw;
                    }
                    else
                    {
                        HandleTransientErrors(e);
                    }
                }
                Console.WriteLine(string.Format("Message sent: Id = {0}, Body = {1}", message.MessageId, message.GetBody<string>()));
                break;
            }
        }
        topicClient.Close();
    }

    private static BrokeredMessage CreateSampleMessage(string messageId, string messageBody)
    {
        BrokeredMessage message = new BrokeredMessage(messageBody);
        message.MessageId = messageId;
        return message;
    }

Answer 1

a）您不能使用.NET中的AMQP。只有这样你才能获得AMQP编码。将TransportType = Amqp附加到连接字符串。然后使用Apache Proton-J的JMS提供程序。

b）如果您使用Java中的HTTP，请尝试通过自序列化流（Stream参数化构造函数）或使用（对象，XmlObjectSerializer）参数化构造函数的DataContractSerializer明确构造消息。这将为您提供XML测试有效负载。默认情况下，我们使用NetDataContractSerializer，它产生一个紧凑的编码，但只是.NET。
