rocketmq 网络传输协议中magic code 是什么

[dhsjgdf]

请问网络传输协议中magic code 是什么？我从RemoteCommand源代码中没看到有magic code,我现在要做一个代理，需要判断是否是rocketmq协议，请问怎么来判断

[leizhiyuan]

用的是LengthFieldBasedFrameDecoder ，不存在magicCode

看看 encode的过程 org.apache.rocketmq.remoting.protocol.RemotingCommand#encode

[lizhanhui]

He is looking for preface of a protocol. For example, SSL/TLS has a negotiation byte: https://tls12.xargs.org/#client-hello/annotated
HTTP2 has connection preface: https://httpwg.org/specs/rfc7540.html#rfc.section.3.5

Unfortunately, RocketMQ lacks this feature and is actually a design flaw.
