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：
