我编写了这个脚本来下载我的歌曲的歌词并将它们存储在一个文本文件中：

>>> lis = os.listdir('D:\Phone\Sounds')
>>> for i in lis:
    print i

    br.open('http://www.azlyrics.com/') # THE PROBLEM

    br.select_form(nr=0)
    track = eyed3.load(i).tag
    if(track.artist != None):
        ft = track.artist.find('ft.')
        if(ft != -1):
            br['q'] = track.title + ' ' + track.artist[:ft]
        else:
            br['q'] = track.title + ' ' + track.artist
    else:
        br['q'] = track.title
    br.submit()
    s = BeautifulSoup(br.response().read())
    a = s.find('div',{'class':'sen'})
    if(a != None):
        s = BeautifulSoup(urllib.urlopen(a.find('a')['href']))
        file = open(i.replace('.mp3','.txt'),'w')
        file.write(str(s.find('div',{'style':'margin-left:10px;margin-right:10px;'})).replace('<br />','\n'))
        file.close()
    else:
        print 'Lyrics not found'

这似乎工作了一段时间，我下载了一些歌曲的歌词，突然它引发了 BadStatusLine 错误

    raise BadStatusLine(line)
BadStatusLine: ''

那么，为什么 br.open 函数突然停止工作？提前致谢 。

httplib当它不理解响应状态代码时会生成错误。引用自文档：

HTTPException 的子类。如果服务器以我们不理解的 HTTP 状态代码响应，则引发。

运行时我没有收到任何错误br.open('http://www.azlyrics.com/')。所以，问题就在你身边。

您很可能正在使用代理，请查看Python 的 mechanize proxy support。

UPD：试试这个：

br = mechanize.Browser()
br.addheaders = [('User-agent', 'Mozilla/5.0 (X11; U; Linux i686; en-US; rv:1.9.0.1) Gecko/2008071615 Fedora/3.0.1-1.fc9 Firefox/3.0.1')]

br.set_debug_http(True)
br.set_debug_redirects(True)
br.set_debug_responses(True)

br.open('http://www.azlyrics.com')

print br.response().read()

希望有帮助。
