How to click on "Verify you are human" checkbox challenge by cloudflare using Selenium

问题

抱歉，我只能为您提供代码的翻译，以下是您提供的Python代码的翻译：

  1. from selenium.webdriver.support.ui import WebDriverWait
  2. from selenium.webdriver.common.by import By
  3. from selenium.webdriver.support import expected_conditions as EC
  4. from selenium import webdriver
  5. import time
  7. chromedriver_path = r"./driver/chromedriver"
  8. browser = webdriver.Chrome(executable_path=chromedriver_path)
  9. url = "https://pace.coe.int/en/aplist/committees/9/commission-des-questions-politiques-et-de-la-democratie"
  10. topics_xpath = '//*[@id="challenge-stage"]/div/label/span[2]'
  11. browser.get(url)
  12. time.sleep(5)  # 等待页面加载
  13. escolhe = browser.find_element("xpath", topics_xpath)
  14. time.sleep(5)
  15. escolhe.click()
  16. time.sleep(5)

希望这可以帮助您解决问题。如果您有其他问题或需要进一步的帮助，请告诉我。

I need to automatically download using Python a .csv file that is in this web page:

  1. https://pace.coe.int/en/aplist/committees/9/commission-des-questions-politiques-et-de-la-democratie

Now, I have written this code:

  1. from selenium.webdriver.support.ui import WebDriverWait
  2. from selenium.webdriver.common.by import By
  3. from selenium.webdriver.support import expected_conditions as EC
  4. from selenium import webdriver
  5. import time
  6. from selenium.webdriver.support import expected_conditions
  7. from selenium.webdriver.support import expected_conditions
  8. from selenium.webdriver.common.by import By
  9. from selenium.webdriver.support.ui import WebDriverWait
  10.  
  11. chromedriver_path = r"./driver/chromedriver"
  12. browser = webdriver.Chrome(executable_path=chromedriver_path)
  13. url = "https://pace.coe.int/en/aplist/committees/9/commission-des-questions-politiques-et-de-la-democratie"
  14. topics_xpath = '//*[@id="challenge-stage"]/div/label/span[2]'
  15. browser.get(url)
  16. time.sleep(5)  #Wait a little for page to load.
  17. escolhe = browser.find_element("xpath", topics_xpath)
  18. time.sleep(5)
  19. escolhe.click()
  20. time.sleep(5)

The web page opens up and I am then prompted to click on "Verify you are human":

I have "inspected" the button and copied the xpath (see code above).
But I get this error:

  1. NoSuchElementException: no such element: Unable to locate element: {"method":"xpath","selector":"//*[@id="challenge-stage"]/div/label/span[2]"}
  2.   (Session info: chrome=114.0.5735.198)

Can anyone help me, please?

与文本“验证您是否为人类”元素相关联的[标签：复选框]位于<iframe>内，因此您需要：

  • 引发WebDriverWait以等待所需的_可用帧并切换到它_。
  • 引发WebDriverWait以等待所需的_可单击元素_。
  • 您可以使用以下任一定位策略之一：
    • 使用_CSS_SELECTOR_：
  1.     driver.get("https://pace.coe.int/en/aplist/committees/9/commission-des-questions-politiques-et-de-la-democratie")
  2.     time.sleep(5)
  3.     WebDriverWait(driver, 20).until(EC.frame_to_be_available_and_switch_to_it((By.CSS_SELECTOR,"iframe[title='Widget containing a Cloudflare security challenge']")))
  4.     WebDriverWait(driver, 20).until(EC.element_to_be_clickable((By.CSS_SELECTOR, "label.ctp-checkbox-label"))).click()
  • 使用_XPATH_：
  1.     driver.get("https://pace.coe.int/en/aplist/committees/9/commission-des-questions-politiques-et-de-la-democratie")
  2.     time.sleep(5)
  3.     WebDriverWait(driver, 20).until(EC.frame_to_be_available_and_switch_to_it((By.XPATH,"//iframe[@title='Widget containing a Cloudflare security challenge']")))
  4.     WebDriverWait(driver, 20).until(EC.element_to_be_clickable((By.XPATH, "//label[@class='ctp-checkbox-label']"))).click()
  • 注意：您需要添加以下导入语句：
  1.     from selenium.webdriver.support.ui import WebDriverWait
  2.     from selenium.webdriver.common.by import By
  3.     from selenium.webdriver.support import expected_conditions as EC

您可以在以下几个相关讨论中找到相关信息：

英文:

The [tag:checkbox] associated with the text Verify you are human element is within an <iframe> so you have to:

  • Induce WebDriverWait for the desired frame to be available and switch to it.

  • Induce WebDriverWait for the desired element to be clickable.

  • You can use either of the following locator strategies:

    • Using CSS_SELECTOR:

      1. driver.get("https://pace.coe.int/en/aplist/committees/9/commission-des-questions-politiques-et-de-la-democratie")
      2. time.sleep(5)
      3. WebDriverWait(driver, 20).until(EC.frame_to_be_available_and_switch_to_it((By.CSS_SELECTOR,"iframe[title='Widget containing a Cloudflare security challenge']")))
      4. WebDriverWait(driver, 20).until(EC.element_to_be_clickable((By.CSS_SELECTOR, "label.ctp-checkbox-label"))).click()

    • Using XPATH:

      1. driver.get("https://pace.coe.int/en/aplist/committees/9/commission-des-questions-politiques-et-de-la-democratie")
      2. time.sleep(5)
      3. WebDriverWait(driver, 20).until(EC.frame_to_be_available_and_switch_to_it((By.XPATH,"//iframe[@title='Widget containing a Cloudflare security challenge']")))
      4. WebDriverWait(driver, 20).until(EC.element_to_be_clickable((By.XPATH, "//label[@class='ctp-checkbox-label']"))).click()

  • Note : You have to add the following imports :

    1.  from selenium.webdriver.support.ui import WebDriverWait
    2.  from selenium.webdriver.common.by import By
    3.  from selenium.webdriver.support import expected_conditions as EC

这是一个用于绕过Cloudflare的完整SeleniumBase脚本。

pip install seleniumbase，然后用python运行：

  1. from seleniumbase import SB
  3. def verify_success(sb):
  4.     sb.assert_element('img[alt="Logo Assembly"]', timeout=8)
  5.     sb.sleep(4)
  7. with SB(uc_cdp=True, guest_mode=True) as sb:
  8.     sb.open("https://pace.coe.int/en/aplist/committees/9/commission-des-questions-politiques-et-de-la-democratie")
  9.     try:
  10.         verify_success(sb)
  11.     except Exception:
  12.         if sb.is_element_visible('input[value*="Verify"]'):
  13.             sb.click('input[value*="Verify"]')
  14.         elif sb.is_element_visible('iframe[title*="challenge"]'):
  15.             sb.switch_to_frame('iframe[title*="challenge"]')
  16.             sb.click("span.mark")
  17.         else:
  18.             raise Exception("Detected!")
  19.         try:
  20.             verify_success(sb)
  21.         except Exception:
  22.             raise Exception("Detected!")

只有在必要时才会点击复选框。使用sb.driver来访问原始的driver。该脚本尽量避免被检测到。

英文:

Here's a complete SeleniumBase script for bypassing Cloudflare on that site.

pip install seleniumbase, then run with python:

  1. from seleniumbase import SB
  3. def verify_success(sb):
  4.     sb.assert_element('img[alt="Logo Assembly"]', timeout=8)
  5.     sb.sleep(4)
  7. with SB(uc_cdp=True, guest_mode=True) as sb:
  8.     sb.open("https://pace.coe.int/en/aplist/committees/9/commission-des-questions-politiques-et-de-la-democratie")
  9.     try:
  10.         verify_success(sb)
  11.     except Exception:
  12.         if sb.is_element_visible('input[value*="Verify"]'):
  13.             sb.click('input[value*="Verify"]')
  14.         elif sb.is_element_visible('iframe[title*="challenge"]'):
  15.             sb.switch_to_frame('iframe[title*="challenge"]')
  16.             sb.click("span.mark")
  17.         else:
  18.             raise Exception("Detected!")
  19.         try:
  20.             verify_success(sb)
  21.         except Exception:
  22.             raise Exception("Detected!")

It will only click the checkbox if necessary. Use sb.driver to access the raw driver. The script tries to avoid detection altogether.
