基于python的socket实现单机五子棋到双人对战
本次实验使用python语言。通过socket进行不同机器见的通信，具体可以分为以下四步：1.创建ServerSocket和Socket；2.打开链接到Socket的输入/输出流；3.按照协议对Socket进行读/写操作；4.关闭输入输出流、关闭Socket。
由于是双人对战，服务器必须应对多人及以上的客户端的连接，因此本实验还引入了python的threading多线程模块，通过监听实时监控网络状态，同时利用socket.listen(2)引入排队等待机制。
chess类

然后是用while循环实现的单机版五子棋
# -*- coding: utf-8 -*-#单机版五子棋from chess import chessboarddef changeid(id):if id==1:return 2elif id==2:return 1else:return 0t=chessboard()id=1#初始化idt.draw()while (not t.is_end()):#end函数print('your id is %d,input your next drop(x,y)'% id)x=input()y=input()x=int(x)y=int(y)if t.drop_chess(x,y,id):t.draw()else:print('_________Illegal Input,Please Check Again_________')continueid=changeid(id)

由于要实现双人对战，所以服务器端必须要用多线程使其服务多个客户端，因此使用threading
服务器端
# -*- coding: utf-8 -*-#服务器import osimport socketimport jsonimport threadingimport timeimport sysfrom chess import chessboardt=chessboard()id=1#初始化iddef handle():while (not t.is_end()):for c in socks:global idjson_string0 = json.dumps(t._chessboard__board)c.sendto(json_string0.encode('utf-8'), address)msg1 = 'Your id is %d,input your next drop' % id + "\r\n"c.send(msg1.encode('utf-8'))msg2x = c.recv(1024)msg2y = c.recv(1024)x = int(msg2x.decode('utf-8'))y = int(msg2y.decode('utf-8'))print('processing......\n')if t.drop_chess(x, y, id):json_string = json.dumps(t._chessboard__board)c.sendto(json_string.encode('utf-8'), address)else:msg3 = '_________Illegal Input,Please Check Again_________'c.send(msg3.encode('utf-8'))continueid = changeid(id)def clear():os.system('cls')def changeid(id):if id==1:return 2elif id==2:return 1else:return 0# 创建 socket 对象s = socket.socket(socket.AF_INET, socket.SOCK_STREAM)# 获取本地主机名host = socket.gethostname()port = 9999# 绑定端口号s.bind((host, port))address=(host, port)# 设置最大连接数，超过后排队s.listen(2)socks=[]th = threading.Thread(target=handle)th.start()while 1:c, addr = s.accept()print'connected from:', addrsocks.append(c)s.close()
然后是客户端
# -*- coding: utf-8 -*-#客户端import socketimport time# 创建 socket 对象c = socket.socket(socket.AF_INET, socket.SOCK_STREAM)# 获取本地主机名#host = socket.gethostname()host='10.41.114.198'# 设置端口号port = 9999# 连接服务，指定主机和端口c.connect((host, port))address=(host, port)while 1:#s=c.accept()print('')print('__________________wait__________________')msg0 = c.recv(2048).decode('utf-8') # 棋盘大于1024for x in msg0:if x == '[':print('')else:print(x, end='')print('')msg1 = c.recv(1024)#接收输入提示print (msg1.decode('utf-8'))time.sleep(1)x = input('x=')y = input('y=')c.send(x.encode('utf-8'))c.send(y.encode('utf-8'))msg3 = c.recv(2048).decode('utf-8')#棋盘大于1024if msg3=='_________Illegal Input,Please Check Again_________':print(msg3)continueelse:#print(msg3)for x in msg3:if x=='[':print('')else:print(x, end='')print('')print('__________________wait__________________')print('')c.close()
注意socket传输时只能传送bytes，因此list先用json转成str，再encode编码
使用方法：先更改客户端host为自己地址，然后先打开服务端，然后打开多个客户端（大于2个开始排队），然后开始输入X,Y坐标开始游戏。
由于时间紧急，暂时未处理单个客户端退出后的程序初始化问题，可能过几日会补上。
