Python下载懒人图库JavaScript特效

这是一个简单的Python脚本，主要从懒人图库下载JavaScript特效模板，在脚本中使用了gevent这个第三方库，使用的时候需要先安装。

#!/usr/bin/python# -*- coding: utf-8 -*- import urllib,os,sysimport gevent,refrom gevent import monkeyfrom bs4 import BeautifulSoupgevent.monkey.patch_socket() '''Description：Python 爬虫抓取懒人图库的JS脚本模板Author：adminCreate-Date：2015-05-25Version：1.0''' HTTP_URL = 'http://www.lanrentuku.com%s'DOWNLOAD_URL = HTTP_URL[:-2] + '/js/d%szip'reg=r'/d{1,}/.+' def encode(text):  return text.encode("utf8") def createDirectory(curPath):  myPath = os.path.join(getSubDirectory(), u'JS代码模板')  if not os.path.exists(myPath):    os.mkdir(myPath)  return os.path.join(myPath, curPath) def getSubDirectory():  return os.getcwd() def schedule(a, b, c):   per = 100.0 * a * b / c  if per > 100 :    per = 100  sys.stdout.write('%.1f%%/r' % per)  sys.stdout.flush() def geturllist(url):  url_list = {}  html = urllib.urlopen(url)  content = html.read()  html.close()  # 用BeautifulSoup解析  decodeHtml = BeautifulSoup(content)  try:    aTags = decodeHtml.find_all('div', {'class':'list-pngjs'})[0].find_all('a')  except IndexError, e:    print e    aTags = None  # 获取链接地址和标题  if aTags is not None:    for a_tag in aTags:      url_list[HTTP_URL % a_tag.get('href')] = a_tag.get_text()  return url_list  def download(down_url):  try:    m=re.search(reg,down_url[0])    name = DOWNLOAD_URL % m.group(0)    urllib.urlretrieve(name,createDirectory(down_url[1] + name[-4:]),schedule)  except Exception, e:    print e.message  def getpageurl(xUrl):  # 进行列表页循环  return [xUrl % page for page in xrange(1,49)] if __name__ == '__main__':  jobs = []  pageurl = getpageurl('http://www.lanrentuku.com/js/p%s.html')  # 爬取所有链接  for i in pageurl:    for k in geturllist(i).items():      jobs.append(gevent.spawn(download, k))  gevent.joinall(jobs)
