python 爬虫刷访问量

import urllib.request
import time

# 使用build_opener()是为了让python程序模仿浏览器进行访问
opener = urllib.request.build_opener()
opener.addheaders = [('User-agent', 'Mozilla/5.0')]

# 专刷某个页面
print('开始刷了哦：')
tempUrl = 'https://www.cnblogs.com/lma0702/p/11106382.html'

for j in range(2000):
try:
opener.open(tempUrl)
time.sleep(7)
print('%d %s' % (j, tempUrl))
except urllib.error.HTTPError:
print('urllib.error.HTTPError')
time.sleep(1)
except urllib.error.URLError:
print('urllib.error.URLError')
time.sleep(1)
