Question

我一直在尝试编写一个python脚本，它将获取播放列表中包含的歌曲的名称，其中将提供链接。例如来自终端的https://www.youtube.com/watch?v=foE1mO2yM04&list=RDGMEMYH9CUrFO7CfLJpaD7UR85wVMfoE1mO2yM04。

我发现可以使用＆＃34; li＆＃34;提取姓名。标签或＆＃34; h4＆＃34;标签。我写了以下代码，

  import sys

link = sys.argv[1]


from bs4 import BeautifulSoup
import requests

req = requests.get(link)

try:
    req.raise_for_status()
except Exception as exc:
    print('There was a problem:',exc)

soup = BeautifulSoup(req.text,"html.parser")

然后我尝试使用li-tag作为：

i=soup.findAll('li')
print(type(i))
for o in i:
    print(o.get('data-video-title'))

但它打印了＃34;无＆＃34;那些时间。我相信它无法达到那些包含data-video-title属性的li标签。
然后我尝试使用div和h4标签，

for i in soup.findAll('div', attrs={'class':'playlist-video-description'}):
    o = i.find('h4')
    print(o.text)

但没有再发生......

Answer 1

import requests
from bs4 import BeautifulSoup

url = 'https://www.youtube.com/watch?v=foE1mO2yM04&list=RDGMEMYH9CUrFO7CfLJpaD7UR85wVMfoE1mO2yM04'

data = requests.get(url)
data = data.text
soup = BeautifulSoup(data)

h4 = soup.find_all("h4")
for h in h4:
    print(h.text)

Answer 2

好的，伙计们，我已经知道发生了什么。我的代码是完美的，它工作正常，问题是我从终端传递链接作为参数，并且同时，链接包含一些符号，这些符号以其他方式解释为例如。（＆＃39;＆安培;＆＃39）。现在我将链接作为字符串传递到终端，一切正常。如此愚蠢又耗时的错误。
