python-3.x - 在 iframe id="swGoogleDrive" 中获取 PDF

Question

如何获取在此URL的 iframe 中找到的 PDF ？

(1) 以下代码抛出错误。

import requests, re
from bs4 import BeautifulSoup

url = r'https://www.d88a.org/domain/102'
headers = {'User-Agent': 'C19SchoolsWebscrape'}

s = requests.Session()
r = s.get(url, headers=headers)

soup = BeautifulSoup(r.content, "lxml")
iframe_src = soup.select_one("swGoogleDrive").attrs["src"]
r = s.get(f"https:{iframe_src}")
print(r)

error: 'NoneType' object has no attribute 'attrs'

(2) 这也会引发错误。

response = requests.get(url, headers=headers)
t = re.search(b'(?<=artist":")(.*?)(?=")', response.content).group(0).decode("utf-8")
print(t)

error: 'NoneType' object has no attribute 'group'

Answer 1

要获取 PDF 的所有链接，您可以使用以下示例：

import requests
from bs4 import BeautifulSoup


url = 'https://www.d88a.org/domain/102'

soup = BeautifulSoup(requests.get(url).content, 'html.parser')
soup = BeautifulSoup(requests.get(soup.iframe['src']).content, 'html.parser')

for a in soup.select('a'):
    print(a['href'])
