How to click on elements within an iframe to enable the captcha through the audio using Selenium and Python

问题

I want to, click on the button to resolve the captcha through the audio, but selenium does not detect the specified "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()

回答1:

To click() on the button to resolve the captcha through the audio as the the desired elements are 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 the following Locator Strategies:

  • Code Block:

    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()
