我们一般都在优酷里看一些好玩的视频，有时候看到精彩的就想下载到本地保存起来留作纪念，在win下可以用维棠等软件下载，但苦了用linux的孩子们。尽管chrome和firefox的一些插件可以下载，但有时候下载下来是分段的视频，还要手动用ffmpeg合成一个视频太繁琐，而且用插件下载要点击好多次鼠标，太不符合linuxer的性格了哈~于是我用python3写了一个youkuDown.py，代码如下：

import re
import urllib.request
import json
import time
import random
import sys

def getVideoInfo(url):
	ruleTitle=re.compile(‘<title>(.*)</title>‘)
	ruleId=re.compile(‘http://v.youku.com/v_show/id_(.*).html‘)
	videoTitle=ruleTitle.findall(urllib.request.urlopen(url).read().decode(‘utf8‘))
	videoId=ruleId.findall(url)
	return videoTitle[0],videoId[0]

def getTrueLink(videoid):
	data=urllib.request.urlopen(‘http://v.youku.com/player/getPlayList/VideoIDS/‘+videoid)
	info=json.loads(data.read().decode(‘utf8‘))

	segs=info[‘data‘][0][‘segs‘]
	types=segs.keys()

	seed=info[‘data‘][0][‘seed‘]
	source=list("abcdefghijklmnopqrstuvwxyzABCDEFGHIJKLMNOPQRSTUVWXYZ/\\:._-1234567890")
	mixed=‘‘
	while source:
		seed=(seed*211+30031)&0xFFFF
		index=seed*len(source)>>16
		c=source.pop(index)
		mixed+=c

	ids=info[‘data‘][0][‘streamfileids‘][‘flv‘].split(‘*‘)[:-1]
	vid=‘‘.join(mixed[int(i)] for i in ids)

	sid=‘%s%s%s‘%(int(time.time()*1000),random.randint(1000,1999),random.randint(1000,9999))

	urls=[]
	for s in segs[‘flv‘]:
		no=‘%02x‘%int(s[‘no‘])
		url=‘http://f.youku.com/player/getFlvPath/sid/%s_%s/st/flv/fileid/%s%s%s?K=%s&ts=%s‘%(sid,no,vid[:8],no.upper(),vid[10:],s[‘k‘],s[‘seconds‘])
		urls.append(url)
	return urls

def down2file(urls,filename):
	f=open(filename,‘wb‘)
	fileNum=len(urls)
	count=0
	for url in urls:
		count+=1
		print(‘downloading file %d/%d‘%(count,fileNum))
		req=urllib.request.Request(url,headers={‘Referer‘:‘http://www.youku.com‘})
		data=urllib.request.urlopen(req).read()
		f.write(data)
	f.close()
	print(‘download ‘+filename+‘ OK!‘)

def youkuDown(link):
	videotitle,videoid=getVideoInfo(link)
	urls=getTrueLink(videoid)
	down2file(urls,videotitle+‘.flv‘)

if __name__==‘__main__‘:
	if len(sys.argv)<2:
		print(‘Example Usage: python3 youkuDown.py http://v.youku.com/v_show/id_XNjUzNDQwMzIw.html‘)
		print(‘‘)
		exit() 
	youkuDown(sys.argv[1])
