jsonproto

jsonproto is implemented JSON socket communication protocol.

Message Bytes

{length bytes} {xferPipe length byte} {xferPipe bytes} {JSON bytes}

• {length bytes}: uint32, 4 bytes, big endian
• {xferPipe length byte}: 1 byte
• {xferPipe bytes}: one byte one xfer
• {JSON bytes}: {"seq":%d,"mtype":%d,"serviceMethod":%q,"status":%q,"meta":%q,"bodyCodec":%d,"body":"%s"}

Usage

Test
