How to read byte attachment in solace
问题
我能够接收到InboundMessage消息。当我将其转储时，我可以看到二进制附件，但无法从InboundMessage中提取二进制附件。
我正在使用Python发布消息，Java消费消息。
有人可以帮助我从InboundMessage中提取二进制附件吗？
二进制附件：len=65
80 04 95 36 00 00 00 00 00 00 00 8c 0b 6d 6f 64 ...6.........mod

I am able to receive the InboundMessage message. When I dump it, I can see Binary Attachment but I am not able to extract Binary Attachment from InboundMessage.
I am using python to publish message and java to consume message.
Can anyone help me to extract Binary Attachment from InboundMessage
Binary Attachment: len=65

如果您使用新的Java API，那么这些可能是您想查看的方法：
Message.getPayloadAsBytes()文档链接Message.getPayloadAsString()文档链接InboundMessage.getAndConvertPayload(Converter, Class)文档链接
如果您使用JCSMP，只需将接收到的BytesXMLMessage强制转换为BytesMessage并获取原始载荷：((BytesMessage)message).getData()。或者，如果您要发布文本消息/字符串载荷，那么应该是((TextMessage)message).getText()。
Solace实际上有4个Java API，还有更多支持Solace的其他协议的API（MQTT，AMQP等）。使用Python发布消息的具体细节以及您正在使用的Java API，请编辑您的问题以提供更多详细信息。

If you are using the new Java API, then these are probably the methods you'd want to check out:
Message.getPayloadAsBytes()Docs linkMessage.getPayloadAsString()Docs linkInboundMessage.getAndConvertPayload(Converter, Class)Docs link
If you are using JCSMP, then just cast the received BytesXMLMessaage to a BytesMessage and get the raw payload: ((BytesMessage)message).getData(). Or if you are publishing a Text message / String payload, then it would be ((TextMessage)message).getText().
Solace has 4 Java APIs, actually, and there are more for the other protocols Solace supports (MQTT, AMQP, etc.). Edit your question with more specifics about how you're publishing in Python & exactly which Java API you're consuming with.
