一.本案例基于UDP的socket编程方法来制作五子棋程序，网络五子棋采用C/S架构，分为服务器端和客户端，游戏时服务端首先启动，当客户端启动连接后，服务器端可以走棋，轮到自己棋才可以在棋盘上落子，同时下方标签会显示对方走起信息，服务器端用户可以通过“退出游戏”按钮可以结束游戏；
1.数据通信协议
网络五子棋游戏设计的难点在于对方进行通信，这里使用面向非连接的Socket编程，Socket编程用于C/S开发，在这类应用中，客户端和服务器端通常需要先建立连接，然后发送和接收数据，交互完成后需要断开连接，本章采用基于UDP的Socket编程实现，这里虽然两台计算机不分主次，但涉及时候假设一台作为服务器端，等待其他方加入，其他想加入必须输入服务器端主机的IP；
下面展示一些 数据通信协议代码。
def receiveMessage():
global s
while True:
global addr
data,addr=s.recvfrom(1024)
data=data.decode('utf-8')
a=data.split("|")
if not data:
print("client has exited!")
break
elif a[0]=='join': #连接服务器请求
print('client 连接服务器！')
label1["text"]='client连接服务器成功，请你走棋！'
elif a[0]=='exit':
print('client 对方退出！')
label1["text"]='client对方退出，游戏结束！'
elif a[0]=='over':
print('对方赢信息！')
label1["text"]=data.split("|")[0]
showinfo(title="提示",message=data.split("|")[1])
elif a[0]=='move':
print('received:',data,'from',addr)
p=a[1].split(",")
x=int(p[0])
y=int(p[1])
print(p[0],p[1])
label1["text"]="客户端走的位置"+p[0]+p[1]
drawOtherChess(x,y)
s.close()
2.判断输赢的算法
本游戏关键技术就是判断输赢的算法，对于算法实现大致可以分为以下几个部分：
（1）判断X=Y轴上是否形成五子连珠；
（2）判断X=-Y轴上是否形成五子连珠；
（3）判断X轴上是否形成五子连珠；
（4）判断Y轴上是否形成五子连珠；
#输赢判断
def win_lose():
a=str(turn)
print("a=",a)
for i in range(0,11):
for j in range(0,11):
if map[i][j]==a and map[i+1][j+1]==a and map[i+2][j+2]==a and map[i+3][j+3]==a and map[i+4][j+4]==a:
print("x=y轴上形成五子连珠")
return True
for i in range(4,15):
for j in range(0,11):
if map[i][j]==a and map[i-1][j+1]==a and map[i-2][j+2]==a and map[i-3][j+3]==a and map[i-4][j+4]==a:
print("x=-y轴上形成五子连珠")
return True
for i in range(0,15):
for j in range(4,15):
if map[i][j]==a and map[i][j-1]==a and map[i][j-2]==a and map[i][j-2]==a and map[i][j-4]==a:
print("Y轴上形成了五子连珠")
return True
for i in range(0,11):
for j in range(0,15):
if map[i][j]==a and map[i+1][j]==a and map[i+2][j]==a and map[i+3][j]==a and map[i+4][j]==a:
print("X轴形成五子连珠")
return True
return False
