Python3.4编程实现简单抓取爬虫功能示例_Python

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)

希望本文所述对大家Python程序设计有所帮助。
