千锋扣丁学堂Python培训之socket实现单机五子棋到双人对战

2019-06-18 13:10:58 1970浏览

今天千锋扣丁学堂Python培训老师给大家分享一篇关于基于python的socket实现单机五子棋到双人对战的详细介绍，首先本次实验使用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

#五子棋类
import os
class chessboard(object):
  def __init__(self):
    self.size = 16
    #初始化棋盘
    self.__board=[[' ' for n in range(self.size)] for m in range(self.size)]

          print('winner=id 2')
          return 2
        if self.size-i-j+1>0:

    ch_stack.clear()
    #下三角
    for i in range(self.size):
      for j in range(1,self.size):
        # 判断是否结束
        if len(ch_stack) == 5 and ch_stack[-1] == '* ':
          print('winner=id 1')
          return 1
        elif len(ch_stack) == 5 and ch_stack[-1] == '@ ':
          print('winner=id 2')
          return 2
        if self.size-i-j> 0:
          chess = self.__board[j][self.size-i-j]
          if chess == ' ':
            ch_stack.clear()
          elif not chess:
            break
          else:
            if (not ch_stack) or ch_stack[-1] == chess:
              ch_stack.append(chess)
            else:
              ch_stack.clear()
              ch_stack.append(chess)
        else:
          break
      ch_stack.clear()
    ch_stack.clear()
    return 0
  def draw(self):
    #clear()
    for x in self.__board:
      print(x)
    return 0
  def drop_chess(self,x,y,id):
    if id==1 and self.__board[x][y]==' ':
      self.__board[x][y]='* '
      return 1
    elif id==2 and self.__board[x][y]==' ':
      self.__board[x][y]='@ '
      return 1
    else:
      return 0

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 chessboard
def changeid(id):
  if id==1:
    return 2
  elif id==2:
    return 1
  else:
    return 0
t=chessboard()
id=1#初始化id
t.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_________')
    continue
  id=changeid(id)

———————分割线———————

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 os
import socket
import json
import threading
import time
import sys
from chess import chessboard
t=chessboard()
id=1#初始化id
def handle():
  while (not t.is_end()):
    for c in socks:
      global id
      json_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'))
        continue
      id = changeid(id)
def clear():
  os.system('cls')
def changeid(id):
  if id==1:
    return 2
  elif id==2:
    return 1
  else:
    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:', addr
  socks.append(c)
s.close()

然后是客户端

# -*- coding: utf-8 -*-
#客户端
import socket
import 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1024
  for 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1024
  if msg3=='_________Illegal Input,Please Check Again_________':
    print(msg3)
    continue
  else:
    #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。
