通过python，采用多线程的方式访问网页。
一个简单的小例子，访问三个不同的页面，每个页面开20个线程并发访问。

 

python脚本如下：

 

#!/usr/bin/env python # -*- coding: utf-8 -*- ''' Created on 2010-7-2 @author: forever ''' import sys import threading from urllib import urlopen urls = ["/archive/2010/07/03/5711257.aspx", "/archive/2010/06/28/5699311.aspx", "/archive/2010/07/03/5711270.aspx", ] visitTimesPerPage = 20 def usage(): print 'Usage:', sys.argv[0], 'host' def main(argv): host = argv[1] if host == '': usage() sys.exit(2) else: for i in range(visitTimesPerPage): for url in urls: visitPageThread = VisitPageThread(url + str(i), host, url) visitPageThread.start() class VisitPageThread(threading.Thread): def __init__(self, threadName, host, url): threading.Thread.__init__(self, name = threadName) self.host = host self.url = url def run(self): url = self.host + self.url try: doc = urlopen(url).read() #print doc except Exception, e: print "urlopen Exception : %s" %e if __name__=='__main__': sys.argv.append('http://blog.csdn.net/forandever') main(sys.argv)
