Web scraping 抓取YouTube播放列表视频链接
我想下载Youtube频道的所有视频。所以我试着用Web scraping 抓取YouTube播放列表视频链接,web-scraping,beautifulsoup,python-2.x,Web Scraping,Beautifulsoup,Python 2.x,我想下载Youtube频道的所有视频。所以我试着用beautifulsou编写一个脚本，以删除视频的所有链接 我做了一些检查，发现“tr class=“pl video yt uix tile”可以用来获取链接。这是Python代码： import urllib2 from bs4 import BeautifulSoup url='https://www.youtube.com/playlist?list=PL3D7BFF1DDBDAAFE5' html=urllib2.urlopen(url
beautifulsoutr class=“pl video yt uix tileimport urllib2
from bs4 import BeautifulSoup
url='https://www.youtube.com/playlist?list=PL3D7BFF1DDBDAAFE5'
html=urllib2.urlopen(url)
response=html.read()
soup=BeautifulSoup(response)
res=soup.find_all('tr',class_="pl-video yt-uix-tile ")
print res
import urllib2
from bs4 import BeautifulSoup
htmlParser = "lxml"
url='https://www.youtube.com/playlist?list=PL3D7BFF1DDBDAAFE5'
html=urllib2.urlopen(url)
response=html.read()
soup=BeautifulSoup(response, htmlParser)
links = soup.find_all('a', attrs={'class':'pl-video-title-link'})
for a in links:
print(a.get("href"))

我没有得到我输出中链接的完整列表。只有前几个（17）输出中只有视频。我使用了与您在答案中输入的相同的代码。我如何修复此问题？提前谢谢。@user6739649我获得了100个链接。我不知道为什么您的链接只有17个。您没有收到任何错误吗？没有错误。您使用的是哪一版本的Python？只有在命令行中执行脚本时，我才能获得17个链接。如果我运行它作为一个脚本，我得到了[]作为输出。@user6739649我使用的版本是2.7.6您的代码为我返回100行，所以逻辑没有问题，bs4的哪个版本？@padraiccningham我使用的是Beauty Soup版本4.3.2和Python 2.7尝试升级，pip安装-Ubs4@PadraicCunningham尝试升级了…现在我得到了部分输出（18个链接）。您的代码也可以在我的系统中运行。知道为什么其他代码不起作用吗？提前谢谢。@user6739649，运行Meysam提供的其他代码时，我没有得到任何输出。@user6739649。原因同样是在“lxml”和“html.parser”中解析代码的方式“不同，请参阅了解更多详细信息。当我在Meysam代码中打印soup并尝试查找类“pl video title link”时，它将返回0个结果，而当我在代码中打印soup并搜索同一类时，它将按预期显示所有100个结果。我对其他代码进行了大约10次迭代，只得到了空白输出
