python实现用于测试网站访问速率的方法_Python

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：

100

101
