Python实现的爬虫功能代码

#encoding=utf-8
import re
import requests
import urllib2
import datetime
import MySQLdb
from bs4 import BeautifulSoup
import sys
reload(sys)
sys.setdefaultencoding("utf-8")
class Splider(object):
  def __init__(self):
  print u'开始爬取内容...'
  ##用来获取网页源代码
  def getsource(self,url):
  headers = {'User-Agent':'Mozilla/5.0 (Macintosh; Intel Mac OS X 10_10_3) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/50.0.2652.0 Safari/537.36'}
  req = urllib2.Request(url=url,headers=headers)
  socket = urllib2.urlopen(req)
  content = socket.read()
  socket.close()
  return content
  ##changepage用来生产不同页数的链接
  def changepage(self,url,total_page):
    now_page = int(re.search('page/(\d+)',url,re.S).group(1))
  page_group = []
  for i in range(now_page,total_page+1):
    link = re.sub('page/(\d+)','page/%d' % i,url,re.S)
    page_group.append(link)
  return page_group
  #获取字内容
  def getchildrencon(self,child_url):
  conobj = {}
  content = self.getsource(child_url)
  soup = BeautifulSoup(content, 'html.parser', from_encoding='utf-8')
  content = soup.find('div',{'class':'c-article_content'})
  img = re.findall('src="/UploadFiles/2021-04-08/(.*">
