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 
 
######################################################################## 
class AsyncGet(asyncore.dispatcher): 
  """ 
  the defined class 
  """ 
 
  #---------------------------------------------------------------------- 
  def __init__(self, host): 
    """Constructor""" 
    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\r\n\r\n" 
    self.outf = None 
    print "连接 :", host 
     
  def handle_connect(self): 
    print 'connect:', self.host 
    pass 
  def handle_read(self): 
    if not self.outf: 
      print '正在连接:',self.host 
    self.outf = open("%s.txt" % self.host, 'wb') 
    data = self.recv(8192) 
    if data: 
      self.outf.write(data) 
     
    pass 
  def handle_writebale(self): 
    return len(self.request) 
     
     
  def handle_write(self): 
    num_sent = self.send(self.request) 
    pass 
   
  def handle_close(self): 
    asyncore.dispatcher.close(self) 
    print "socket close in:",self.host 
    if self.outf: 
      self.outf.close() 
    pass 
   
if __name__ == "__main__": 
  AsyncGet("www.python.org") 
  asyncore.loop() 
 
import asyncore,socket

    self.outf = open("%s.txt" % self.host, 'wb') 
    data = self.recv(8192) 
    if data: 
      self.outf.write(data) 
     
    pass 
  def handle_writebale(self): 
    return len(self.request) 
     
     
  def handle_write(self): 
    num_sent = self.send(self.request) 
    pass 
   
  def handle_close(self):
