如何使用python硒在Google验证码测试页上找到iframe

Question

我正在尝试访问此页面上的iframe：https://www.google.com/recaptcha/api2/demo。这是您必须点击带有图片的iframe。 iframe出现，然后单击“我不是机器人”按钮。您必须使用硒才能起作用，如果您在chrome中手动进行操作，它将无法正常工作。

代码：

from selenium import webdriver

driver = webdriver.Chrome()
driver.get('https://www.google.com/recaptcha/api2/demo')
iframe = driver.find_element_by_xpath('//*[@id="recaptcha-demo"]/div/div/iframe')
driver.switch_to.frame(iframe)
driver.find_element_by_class_name('recaptcha-checkbox').click()
#choose new iframe with pictures - doesn't work
iframe = driver.find_element_by_xpath('/html/body/div[2]/div[4]/iframe')

这里是什么问题？tnx，vasja

要在reCAPTCHA click()上调用checkbox，您需要：

• 将WebDriverWait设置为所需的[[框架可用并切换到它]]。将
• WebDriverWait
表示为所需的[[可点击的元素。您可以使用以下Locator Strategies：

• from selenium import webdriver
  from selenium.webdriver.common.by import By
  from selenium.webdriver.support.ui import WebDriverWait
  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:\Utility\BrowserDrivers\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-checkbox.goog-inline-block.recaptcha-checkbox-unchecked.rc-anchor-checkbox"))).click()
