python实现用于测试网站访问速率的方法

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('
')
if __name__=='__main__':
 Process('http://www.baidu.com',100)

运行结果如下：
