My message use msgPack to serialization and use snappy to compress , when i use amqpcpp to load it, the object AMQPMesage will no return the length of message, i only get the char* using getMessage() in AMQPMessage. So if the message is binary format , using amqp will not get the right message body.

My message is like this ,i use rabbit-c to dump it.
