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  ######################################################################## 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()

结果文件的内容为:
