Question

    hdr = {'User-Agent': 'Mozilla/5.0'}
    url = "https://www.youtube.com/results?search_query=%s+%s" % (artistName, songName)
    req = urllib2.Request(url, headers=hdr)
    page = urllib2.urlopen(req)
    soup = BeautifulSoup(page)
    for SongTitle in soup.findAll('a', {'class': 'yt-uix-tile-link yt-ui-ellipsis yt-ui-ellipsis-2 yt-uix-sessionlink     spf-link '}):
        song_titles.append(SongTitle.string)
        i += 1

所以这是我用来搜索带有自定义网址的YouTube页面的代码。之后，用户可以根据视频号码选择要下载的视频。问题是，我尝试下载的大多数视频都会返回以下错误：

WARNING:root:ciphertag doesn't match signature type

只有非常少量的视频才有效。我已经用Google搜索并找到类似的东西的答案，它说插入一个标题，所以我做了但它仍然无法正常工作。提前谢谢！

HTTP错误403：尝试使用Pafy下载YouTube视频时被禁止
