现在无论是视频还是音乐的版权意识都开始建立起来了，但是资源不集中，导致老是要开启多个视频网站的会员才能够看完自己想要的视频资源，这样实在是太鸡肋。今天黑洞代理就教大家用Python去抓取腾讯视频的视频资源：

# -*- coding: utf-8 -*-

import re

import urllib2

from bs4 import BeautifulSoup

import string, time

import pymongo

NUM = 0 #全局变量,电影数量

m_type = u'' #全局变量,电影类型

m_site = u'qq' #全局变量,电影网站

#根据指定的URL获取网页内容

def gethtml(url):

req = urllib2.Request(url)

response = urllib2.urlopen(req)

html = response.read()

return html

#从电影分类列表页面获取电影分类

def gettags(html):

global m_type

soup = BeautifulSoup(html) #过滤出分类内容

#print soup

#

tags_all = soup.find_all('ul', {'class' : 'clearfix _group' , 'gname' : 'mi_type'})

#print len(tags_all), tags_all

#print str(tags_all[1]).replace('

#动作

re_tags = r'.+?'

p = re.compile(re_tags, re.DOTALL)

tags = p.findall(str(tags_all[0]))

if tags:

tags_url = {}

#print tags

for tag in tags:

tag_url = tag[0].decode('utf-8')

#print tag_url

#获取每个分类的页数

#print soup

#25

re_pages = r'(.+?)'

p = re.compile(re_pages, re.DOTALL)

#print pages

if len(pages) > 1:

def getmovielist(html):

print "%s : %d" % ("=" * 70, NUM)

print values

playlinks.insert(values)

#else:

def getmovieinfo(url):

def insertdb(movieinfo):

if __name__ == "__main__":

#print tags_url

#print tag_urls

for url in tag_urls.items():

print str(url[1]).encode('utf-8') #,url[0]

maxpage = int(get_pages(str(url[1]).encode('utf-8')))

print maxpage

for x in range(0, maxpage):

time.sleep(0.1)

这样我们就能够把企鹅家的视频给抓取下来了，学好这个抓取代码，日后想看哪个就抓取哪个下来。
