如何使用 Python 和 Selenium 通过 cookie 协议页面？

Question

我对 selenium 和 python 很陌生。我正在尝试浏览网页 (https://www.heise.de/download/)，但无法通过 cookiewall（cookie 协议页面）。 webdriver 好像找不到可以点击的按钮

HTML代码：

<button type="button" backgroundcolor="[object Object]" data-testid="uc-accept-all-button" fullwidth="true" class="sc-bdnylx fmRkNf">Alles akzeptieren</button>

from selenium import webdriver
from time import sleep
from selenium.webdriver.common.by import By
from selenium.webdriver.support.wait import WebDriverWait
from selenium.webdriver.support import expected_conditions as EC

# Using Firefox to access web
driver = webdriver.Firefox(executable_path=r'C:\Users\aphro\Anaconda3\geckodriver.exe')

# Open the website
driver.get('https://www.heise.de/download/')
sleep(5)
if driver.find_element_by_xpath('//*[@id="usercentrics-root"]'):
    print("found popup window")

# find button class
wait = WebDriverWait(driver, 10)
element = wait.until(EC.element_to_be_clickable((By.XPATH, '//div[@class="sc-bdnylx fmRkNf"]')))
element.click()

错误信息：

Traceback (most recent call last):
  File "<input>", line 1, in <module>
  File "C:\Program Files\JetBrains\PyCharm Community Edition 2020.1.1\plugins\python-ce\helpers\pydev\_pydev_bundle\pydev_umd.py", line 197, in runfile
    pydev_imports.execfile(filename, global_vars, local_vars)  # execute the script
  File "C:\Program Files\JetBrains\PyCharm Community Edition 2020.1.1\plugins\python-ce\helpers\pydev\_pydev_imps\_pydev_execfile.py", line 18, in execfile
    exec(compile(contents+"\n", file, 'exec'), glob, loc)
  File "C:/Users/aphro/PycharmProjects/SoftwareProject/SoftwareProject/webControl.py", line 18, in <module>
    x = WebDriverWait(driver, 10).until(EC.visibility_of_element_located((By.CSS_SELECTOR, "div[data-testid='uc-accept-all-button'][role='button']"))).click()
  File "C:\Users\aphro\AppData\Roaming\Python\Python38\site-packages\selenium\webdriver\support\wait.py", line 80, in until
    raise TimeoutException(message, screen, stacktrace)
selenium.common.exceptions.TimeoutException: Message:

我尝试了不同的方法，包括 CSS 选择器和 XPATH。我使用 Python 3.8 和 Selenium 3.141。

任何人都可以指出正确的方向，告诉我如何绕过这个 cookiewall（人为 'click' 按钮）并转到实际网页吗？

元素 Alles akzeptieren 在 .

内

解决方案

要点击 Alles akzeptieren，您必须使用 and you can use the following :

代码块：

driver.get("https://www.heise.de/download/")
time.sleep(5)
element = driver.execute_script("""return document.querySelector('#usercentrics-root').shadowRoot.querySelector('footer div div div button[data-testid="uc-accept-all-button"]')""")
element.click()
