python - 如何使用 Selenium 和 Python 与 reCAPTCHA 音频元素交互

Question

我想，点击按钮通过音频解析验证码，但是selenium没有检测到指定的“id”。

browser.get("https://www.google.com/recaptcha/api2/demo")
mainWin = browser.current_window_handle  
iframe = browser.find_elements_by_tag_name("iframe")[0]
browser.switch_to_frame(iframe)
CheckBox = WebDriverWait(browser, 10).until(EC.presence_of_element_located((By.ID ,"recaptcha-anchor"))).click()
sleep(4)
audio = WebDriverWait(browser, 10).until(EC.presence_of_element_located((By.ID ,"recaptcha-audio-button"))).click()

Answer 1

致click()按钮上通过音频解析验证码，因为所需的元素位于 <iframe> 内所以你必须:

• 引发WebDriverWait以使所需的框架可用并切换到它。

• 引发WebDriverWait以使所需的元素可点击。

• 您可以使用以下 Locator Strategies :

• 代码块:

  from selenium import webdriver
  from selenium.webdriver.support.ui import WebDriverWait
  from selenium.webdriver.common.by import By
  from selenium.webdriver.support import expected_conditions as EC
  
  options = webdriver.ChromeOptions() 
  options.add_argument("start-maximized")
  options.add_experimental_option("excludeSwitches", ["enable-automation"])
  options.add_experimental_option('useAutomationExtension', False)
  driver = webdriver.Chrome(options=options, executable_path=r'C:\WebDrivers\chromedriver.exe')
  driver.get("https://www.google.com/recaptcha/api2/demo")
  WebDriverWait(driver, 10).until(EC.frame_to_be_available_and_switch_to_it((By.CSS_SELECTOR,"iframe[src^='https://www.google.com/recaptcha/api2/anchor']")))
  WebDriverWait(driver, 10).until(EC.element_to_be_clickable((By.CSS_SELECTOR, "span#recaptcha-anchor"))).click()
  driver.switch_to.default_content()
  WebDriverWait(driver, 10).until(EC.frame_to_be_available_and_switch_to_it((By.CSS_SELECTOR,"iframe[title='recaptcha challenge']")))
  WebDriverWait(driver, 10).until(EC.element_to_be_clickable((By.CSS_SELECTOR, "button#recaptcha-audio-button"))).click()
