python实现用于测试网站访问速率的方法

614次阅读  |  发布于5年以前

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:
