基于进程内通讯的python聊天室实现方法

本文实例讲述了基于进程内通讯的python聊天室实现方法。分享给大家供大家参考。具体如下：

    #!/usr/bin/env python

    import sys
    import os
    from multiprocessing import connection
    ADDR = ('', 9997)
    AUTH_KEY = '12345'
    class Server(object):
      def __init__(self, username):
        self.auth_key = AUTH_KEY
        self.addr = ADDR
        self.username = username
        self.listener = connection.Listener(self.addr, authkey=self.auth_key)
      def listen(self):
        while True:
          conn = self.listener.accept()
          while True:
            try:
              request = conn.recv()
              response = self.response(request)
              conn.send(response)
            except EOFError:
              break
          conn.close()
      def reply(self):
        message = raw_input("%s: " % self.username)
        return message
      def output_request(self, request):
        sys.stdout.write('%s says: %s\n' % request)
      def response(self, request):
        self.output_request(request)
        response = (self.username, self.reply())
        return response
    class Client(object):
      def __init__(self, username):
        self.auth_key = AUTH_KEY
        self.addr = ADDR
        self.username = username
        self.display_name = self.make_display_name(username)
      def make_display_name(self, username):
        return "%s: " % username
      def connect(self):
        self.conn = connection.Client(self.addr, authkey=self.auth_key)
        while True:
          message = raw_input(self.display_name)
          self.send(message)
          response = self.conn.recv()
          self.output_response(response) 
      def send(self, message):
        self.conn.send((self.username, message))
      def output_response(self, response):
        sys.stdout.write('%s says: %s\n' % response)
    def main():
      mode = sys.argv[1]
      if mode == 'server':
        username = raw_input("Your name please: ")
        server = Server(username)
        server.listen()
      elif mode == 'client':
        username = raw_input("Your name please: ")
        client = Client(username)
        client.connect()
    if __name__ == '__main__':
      main()
