这篇文章主要介绍了Python3.4编程实现简单抓取爬虫功能,涉及Python3.4网页抓取及正则解析相关操作技巧,需要的朋友可以参考下
本文实例讲述了Python3.4编程实现简单抓取爬虫功能。分享给大家供大家参考，具体如下：
import urllib.request
import urllib.parse
import re
import urllib.request,urllib.parse,http.cookiejar
import time
def getHtml(url):
cj=http.cookiejar.CookieJar()
opener=urllib.request.build_opener(urllib.request.HTTPCookieProcessor(cj))
opener.addheaders=[('User-Agent','Mozilla/5.0 (Windows NT 6.1; WOW64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/41.0.2272.101 Safari/537.36'),('Cookie','4564564564564564565646540')]
urllib.request.install_opener(opener)
page = urllib.request.urlopen(url)
html = page.read()
return html
#print ( html)
#html = getHtml("http://weibo.com/")
def getimg(html):
html = html.decode('utf-8')
reg='"screen_name":"(.*?)"'
imgre = re.compile(reg)
src=re.findall(imgre,html)
return src
#print ("",getimg(html))
uid=['2808675432','3888405676','2628551531','2808587400']
for a in list(uid):
print (getimg(getHtml("http://weibo.com/"+a)))
time.sleep(1)以上是基于Python3.4实现简单抓取爬虫功能详细介绍的详细内容。更多信息请关注PHP中文网其他相关文章！
