這篇文章主要介紹了python實(shí)現(xiàn)用于測(cè)試網(wǎng)站訪問速率的方法,涉及Python中urllib2模塊及時(shí)間的相關(guān)操作技巧,需要的朋友可以參考下

這是python編寫的用于測(cè)試網(wǎng)站訪問速率的代碼片段，可以輸出打開某url的時(shí)間，訪問100次的平均時(shí)間，最大時(shí)間和最小時(shí)間等等

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
    #超過一秒的
    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)

運(yùn)行結(jié)果如下：
