beautifulsoup webscraper 问题：无法在网页上找到表格

Question

我想使用以下代码从 this 网站获取表格：

from urllib.request import urlopen as uReq
from bs4 import BeautifulSoup as soup

my_url = 'https://www.flashscore.pl/pilka-nozna/'
uClient = uReq(my_url)
page_html = uClient.read()
uClient.close()
page_soup = soup(page_html, "html.parser")
containers = page_soup.find_all('table', {'class': 'soccer'})

print(len(containers))

但是当我尝试检查 print(len(containers)) 得到了多少表时，我得到了 0。有什么解决办法吗？

页面可能是动态的。您可以像我在这里所做的那样使用 requests-html which allows you to let the page render before pulling the html, or you can use Selenium。

这导致 table class="soccer"

的 42 个元素

import bs4 
from selenium import webdriver 

url = 'https://www.flashscore.pl/pilka-nozna/'

browser = webdriver.Chrome('C:\chromedriver_win32\chromedriver.exe')
browser.get(url)

html = browser.page_source
soup = bs4.BeautifulSoup(html,'html.parser')  

containers = soup.find_all('table', {'class': 'soccer'})

browser.close()

In  [11]: print(len(containers))
42
