本文实例讲述了python使用多线程不断刷新网页的方法。分享给大家供大家参考。具体如下：

这段代码可以开通过个线程不断刷新指定的页面，可用于刷票，增加网页访问量等等，不用再去按F5了

import thread import urllib2 import sys import time def usage(): print 'Usage: python ' + sys.argv[0] + ' <url> <threads>' sys.exit() def reloader(numthread): url = sys.argv[1] numreloads = 0 while True: try: urllib2.urlopen(url) numreloads = numreloads + 1 except KeyboardInterrupt: sys.exit('nProcess aborted.') def splash(): print 'welcome to http://www.jb51.net/codes ' if len(sys.argv) < 3: usage() if __name__ == '__main__': splash() print '[!] DoSing ' + sys.argv[1] + ' with ' + sys.argv[2] + ' threads.' for reloadspawn in range(0, int(sys.argv[2])): thread.start_new_thread(reloader, (reloadspawn,)) sys.stdout.write('') dosind = ['-', '', '|', '/'] dosstat = 0 while True: try: sys.stdout.write('r' + dosind[dosstat % 4] + ' DoSing...') sys.stdout.flush() dosstat = dosstat + 1 time.sleep(0.25) except KeyboardInterrupt: sys.exit('nProcess aborted.')

希望本文所述对大家的Python程序设计有所帮助。
