python实现用于测试网站访问速率的方法

这是python编写的用于测试网站访问速率的代码片段，可以输出打开某url的时间，访问100次的平均时间，最大时间和最小时间等等

import urllib2from datetime import * import timedef Process(url,n):  minSpan = 10.0  maxSpan = 0.0  sumSpan= 0.0  over1s = 0  for i in range(n):    startTime = datetime.now()    try:      res = urllib2.urlopen(url,timeout=10)    except:      pass    endTime = datetime.now()    span = (endTime-startTime).total_seconds()    sumSpan = sumSpan + span    if span < minSpan:      minSpan = span    if span > maxSpan:      maxSpan = span    #超过一秒的    if span>1:      over1s=over1s + 1    print(u'%s Spent :%s seconds'%(url,span))  print(u'requested:%s times,Total Spent:%s seconds,avg:%s seconds, max:%s seconds,min:%s seconds,over 1 secnod:%s times'%(n,sumSpan,sumSpan/n,maxSpan,minSpan,over1s))  print('/n')if __name__=='__main__':  Process('http://www.baidu.com',100)

运行结果如下：
