gserver

This project aims to provide a solution for real-time message flow.
You can create GameServer or others, with gserver.
The communication protocol of GateWay has supported Tcp and Websocket.
DEMO is here. (tcp-gateway and mobagame-service)

TODO

current version is v0.8.3
next version-v0.9.0 will focus on:
1.optimize safe -- ING
2.optimize microservice
3.add inner logger -- ING
4.add tcp gateway -- DONE
5.add game util package(aoi,space,entity....) -- ING

Message

client->gateway
	----------------------------
	| len | seq | id | message |
	----------------------------
	len:seq + id + message，占用2个字节(uint16)
	seq:从1自增的序列号，占用4个字节(uint32)
	id:协议号，占用2个字节(uint16)
	message:业务数据，占用len-6字节，可以使用任意编码：pb/json等，本框架内置了pb2编码器

gateway->client
	----------------------
	| len | id | message |
	----------------------
	len:id + message的长度，占用2个字节(uint16)
	id:协议号，占用两个字节(uint16)
	message:业务数据，占用len-2字节，可以使用任意编码：pb/json等，本框架内置了pb2编码器
