最近了解python的socket编程，写了个小的例子

客户端代码：

#!/usr/bin/env python  # -*- coding:utf-8 -*-    import socket  import logging      def client_connect():      s = socket.socket(socket.AF_INET, socket.SOCK_STREAM, 0)      s.connect(('127.0.0.1', 8080))      import time        time.sleep(2)      s.send("1")      print '1::', s.recv(1024)        s.close()      if __name__ == '__main__':      client_connect()

服务器端代码：

#!/usr/bin/env python  # -*- coding:utf-8 -*-    import socket  import logging      def listen():      s = socket.socket(socket.AF_INET, socket.SOCK_STREAM, 0)      s.bind(('localhost', 8080))      s.listen(5)      while True:          connection, address = s.accept()          print 'connection:::', connection          print 'address:::', address            try:              connection.settimeout(5)              buf = connection.recv(1024)              print 'buf::', buf              if buf == '1':                  connection.send("welcome to server!")              else:                  connection.send("please go out.")          except socket.timeout:              print 'time out'            connection.close()      if __name__ == '__main__':      print 'begin...'      listen()      print 'end...'
