update at 2012.2.29: 传送门 to isnowfy大牛的方法

参考各种资料写的,有个小缺点是需要输入有多少页加心歌曲
改改输出格式应该可以用小众软件里介绍的E音乐盒批量下载吧
当时不知道这个软件,只好又写个爬谷歌音乐的,然后手动下载,真是蛋疼

python 2.7 + BeautifulSoupct

# coding: utf-8

from BeautifulSoup import BeautifulSoup
import urllib,urllib2,cookielib

loginurl='http://www.douban.com/accounts/login'
url='http://douban.fm/mine?start=%d&type=liked'
captchaurl='http://www.douban.com/misc/captcha?id=%s&size=s'
email=raw_input('email:')
passwd=raw_input('passwd:')
pages=int(raw_input('pages:'))

cookie_support= urllib2.HTTPCookieProcessor(cookielib.CookieJar())
opener = urllib2.build_opener(cookie_support, urllib2.HTTPHandler)
urllib2.install_opener(opener)

content=urllib2.urlopen(loginurl).read()

postdata=urllib.urlencode({
    'source':'simple',
    'form_email':email,
    'form_password':passwd,
    #'captcha-id':captchaid,
    #'captcha-solution':raw_input('code in pic:'),
    #'user_login':'登录',
})

req = urllib2.Request( url = loginurl, data = postdata)
content=urllib2.urlopen(req).read()

if opener.open(req).geturl() == 'http://www.douban.com/':
    print 'login success!'
    for i in range(pages):
        content=urllib2.urlopen(url % (i*9,)).read()
        soup=BeautifulSoup(str(content))
        for tr in soup.findAll('tr')[1:]:
            td=tr.findAll('td')
            print td[0].string,td[1].span.string #,td[1].a.string # title artist album
else:
    print 'login fault'

update:登录方式有变化,douban现在会对频繁登录的ip加验证码,总之此代码有时效性,仅供参考

另附一个从baidu爬歌曲url的脚本,把上面脚本的结果保存成文件,再用这个脚本得到url,最后再用downthemall或迅雷批量下载,多么蛋疼
