使用Beautifulsoup和Python进行网页抓取无法工作

Question

我试图从以下页面获得网站地址列表:https://www.wer-zu-wem.de/dienstleister/filmstudios.html

我代码:

import requests
from bs4 import BeautifulSoup
result = requests.get("https://www.wer-zu-wem.de/dienstleister/filmstudios.html")
src = result.content
soup = BeautifulSoup(src, 'lxml')
links = soup.find_all('a', {'class': 'col-md-4 col-lg-5 col-xl-4 text-center text-lg-right'})
print(links)
import requests
from bs4 import BeautifulSoup
webLinksList = []
result = requests.get(
"https://www.wer-zu-wem.de/dienstleister/filmstudios.html")
src = result.content
soup = BeautifulSoup(src, 'lxml')

website_Links = soup.find_all(
'div', class_='col-md-4 col-lg-5 col-xl-4 text-center text-lg-right')

if website_Links != "":
print("List is empty")
for website_Link in website_Links:
try:
realLink = website_Link.find(
"a", attrs={"class": "btn btn-primary external-link"})
webLinksList.append(featured_challenge.attrs['href'])
except:
continue
for link in webLinksList:
print(link)

list is empty"在开始时打印，并且我所做的任何尝试都没有向列表中添加任何数据。

Answer 1

尝试以下链接获取所有指向外部网站的链接:

import requests
from bs4 import BeautifulSoup
link = "https://www.wer-zu-wem.de/dienstleister/filmstudios.html"
headers = {
'User-Agent': 'Mozilla/5.0 (Windows NT 6.1) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/88.0.4324.150 Safari/537.36'
}
result = requests.get(link,headers=headers)
soup = BeautifulSoup(result.text,'lxml')
for links in soup.find_all('a',{'class':'external-link'}):
print(links.get("href"))

Answer 2

试试这个:

import requests
from bs4 import BeautifulSoup
headers = {

"User-Agent": "Mozilla/5.0 (Windows NT 10.0; Win64; x64; rv:85.0) Gecko/20100101 Firefox/85.0",
}
result = requests.get("https://www.wer-zu-wem.de/dienstleister/filmstudios.html", headers=headers)
src = result.content
soup = BeautifulSoup(src, 'lxml')
links = soup.find('ul', {'class': 'wzwListeFirmen'}).findAll("a")
print(links)
