本文实例讲述了python中asyncore模块的用法，分享给大家供大家参考。具体方法如下：

实例代码如下:

##asyncore 
 
import asyncore,socket

 asyncore.dispatcher.__init__(self) 
 self.host = host 
 self.create_socket(socket.AF_INET, socket.SOCK_STREAM) 
 self.connect((host, 80)) 
 self.request = "Get /index.html HTTP/1.0

" 
 self.outf = None 
 print "连接 :", host
