python 爬取微博信息
新浪微博爬取的话需要设计到登录,这里我没有模拟登录,而是使用cookie进行爬取。
获取cookie:
代码:
#-*-coding:utf8-*- from bs4 import BeautifulSoup import requests import time import os import sys import random reload(sys) sys.setdefaultencoding(‘utf-8‘) user_id = 用户id cookie = {"Cookie": "_T_WM=f3a2assae4335dfdf38fdc7a25a88; SCF=ApMI3mluv9yH6yKz4i7-HMlHojzPtQULc5G0xlrri-NeO3Xn1FRWI5W1HElZWG1bMkX4mV_OhKDtNV2IhxJQGLs.; SUB=_2A250jET_DeRhGeNN7FsX9CrIzzqIHXVXj2y3rDV6PUJbkdBeLUrnkW1AtfoOlrd_kyd1Izu7Q1uKaFvRDQ..; SUHB=0k1ySJSrJVBDGD; SSOLoginState=1502098607"} for page in range(100): url = ‘https://weibo.cn/573550093?page=%d‘ % page response = requests.get(url, cookies = cookie) html = response.text soup = BeautifulSoup(html, ‘lxml‘) username = soup.title.string cttlist = [] for ctt in soup.find_all(‘span‘,class_="ctt"): cttlist.append(ctt.get_text()) ctlist = [] for ct in soup.find_all(‘span‘,class_="ct"): ctlist.append(ct.get_text()) if page == 0: print "微博用户资料:" + cttlist[0] print "微博用户个性签名:" + cttlist[1] print "用户的微博动态:\n" imgurllist = [] for img in soup.find_all(‘a‘): if img.find(‘img‘) is not None : if ‘http://tva3.‘ not in img.find(‘img‘)[‘src‘] and ‘https://h5‘ not in img.find(‘img‘)[‘src‘]: imgurllist.append(img.find(‘img‘)[‘src‘]) #imgname = soup.title.string + ‘_‘ + str(page) + str(time.time()) +str(random.randrange(0, 1000, 3)) +‘.jpg‘ if not os.path.exists(str(soup.title.string)): os.mkdir(str(soup.title.string)) #imgname =‘./‘+ str(soup.title.string) + ‘/‘+ soup.title.string + ‘_‘ + str(time.time()) +‘.jpg‘ for imgurl in imgurllist: imgname = ‘./‘+ str(soup.title.string) + ‘/‘+soup.title.string + ‘_‘ + str(page) + str(time.time()) +str(random.randrange(0, 1000, 3)) +‘.jpg‘ response = requests.get(‘%s‘ % imgurl) dirw = str(soup.title.string) open(imgname, ‘wb‘).write(response.content) time.sleep(1.5) try: for i in range(len(ctlist)): print cttlist[2+i] print ctlist[i] print "\n" except: for i in range(len(ctlist)): print cttlist[i] print ctlist[i] print "\n" if "下页" not in soup.select(‘div[id="pagelist"]‘)[0].get_text(): break time.sleep(random.randint(1,3))
