利用Python对网站进行测速

利用python可以编写的用于测试网站访问速率的代码，实现原理是输出打开某url的时间，并计算出访问100次的平均时间，时间和最小时间等等。根据时间的变化判断网站速度。

完整代码：

importurllib2
fromdatetimeimport*
importtime
defProcess(url,n):
minSpan=10.0
maxSpan=0.0
sumSpan=0.0
over1s=0
foriinrange(n):
startTime=datetime.now()
try:
res=urllib2.urlopen(url,timeout=10)
except:
pass
endTime=datetime.now()
span=(endTime-startTime).total_seconds()
sumSpan=sumSpan+span
ifspan<minSpan:
minSpan=span
ifspan>maxSpan:
maxSpan=span
#超过一秒的
ifspan>1:
over1s=over1s+1
print(u'%sSpent:%sseconds'%(url,span))
print(u'requested:%stimes,TotalSpent:%sseconds,avg:%sseconds,max:%sseconds,min:%sseconds,over1secnod:%stimes'%(n,sumSpan,sumSpan/n,maxSpan,minSpan,over1s))
print('\n')
if__name__=='__main__':
Process('http://www.baidu.com',100)

运行结果如下：
