Golang makes a game server for the landlord [7]: some thoughts on servers and protocols

When a client comes over, it must first verify its own identity (check in its own account system), and after the verification, the data is temporarily stored in the central server

The client enters Doudizhu’s server at this time,  

At this time, the client will first communicate with the Doudizhu server.

" Hello server, what version are you? How many people are there now? "

" I am Doudizhu server, my version is 1.0, I have XX tables in it now. There are XX people "

" Can you tell me about the first 100 tables?"

"The first 100 tables are as follows: 3 people at the first table have started the game, 3 people at the second table, have started the game, .... 1 person at the 50th table, waiting "

" Server, I want to join table XXX/server, can you help me quickly find an empty seat? "

" Okay, it has been arranged for you to do it at table XXX. The situation in table XXX is like this "

" A new player comes in "

" Another new player comes in "

"The game officially starts now "

" Your hand is XXXXX "

" Do you want to call the landlord? "

" Call the landlord "

" The situation of other people grabbing landlords is like this "

"The final landlord is XXX "

"The game has officially started, please play the cards "

" I passed "

" Ok, the cards played by others are "

"The game is over, how much money did you get "

" I want to play/not play anymore "

 

The above is almost all the protocols used in the game

First, we simply define an agreement

The protocol is divided into requests from the client to the server. The server replies to the client, one question and one answer, this structure Request Respone,   and the server actively broadcasts this structure to the client BoardCast

Use pb to simply define a protocol first, golang using json is simply cheating
