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 urllib2
from datetime import *
import time
def 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：
