HomeBackend DevelopmentPython Tutorialpython socket多线程通讯实例分析(聊天室)

本文实例讲述了python socket多线程通讯方法。分享给大家供大家参考,具体如下:

#!/usr/bin/evn python
"""
这是一个Socket+多进程的例子(聊天服务端)
"""
import socket
import threading
# 处理中文数据用的
encoding = "GBK"
def HKServer(client, addr):
 """
 与客户端时实通讯函数
 加入encoding是为了处理输入中文数据
 client 客户socket
 addr  客户address
 """
 # 通知已有的每个客户,有新的成员加入
 for c in clients: c.send(bytes("[%s]加入\r\n" % addr[1], encoding))
 # 接受客户端数据
 say = b""
 while True:
  data = client.recv(1024)
  if not data: break
  # 如果不是回车键
  if data != b'\r\n':
   say += data #.encode(encoding)
   continue
  # 把客户端发来的内容发给所有的客户端
  for c in clients:
   c.send(bytes("[%s]:%s\r\n" % (addr[1], say.decode(encoding)), encoding))
  # 内容归\x0
  say = b""
 # 客户离开后,从客户列表中移队当前客户,关闭socket连接
 clients.remove(client)
 client.close()
 # 通知已有的每个客户,有成员离开
 for c in clients: c.send(bytes("[%s]离开\r\n" % addr[1], encoding))
# 客户端列表
clients = []
# 设置IP地址与端口
HOST = ''
PORT = 9999
# 初始化socket
s = socket.socket(socket.AF_INET, socket.SOCK_STREAM)
# 绑定IP地址与端口
s.bind((HOST, PORT))
# 开始监听
s.listen(1)
# 循环等待
while True:
 # 接受客户
 client, addr = s.accept()
 # 启动新的进程与客户通信
 thread = threading.Thread(target=HKServer, args=(client, addr))
 thread.start()
 # 记录新的客户
 clients.append(client)

希望本文所述对大家Python程序设计有所帮助。
