实例代码如下:
##asyncore
import asyncore,socket
########################################################################

#----------------------------------------------------------------------
def __init__(self, host):

self.host = host
self.create_socket(socket.af_inet, socket.sock_stream)
self.connect((host, 80))

self.outf = none

结果文件的内容为:
<!doctype html public "-//ietf//dtd html 2.0//en"> <html><head> <title>302 found</title> </head><body> <h1>found</h1> <p>the document has moved <a href="http://www.python.org">here</a>.</p> <hr> <address>apache/2.2.16 (debian) server at dinsdale.python.org port 80</address> </body></html>
希望本文所述对大家的python程序设计有所帮助。
