Python3.4编程实现简单抓取爬虫功能示例
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)
