Python: Headless mode picks up the older version of chrome

问题

I am trying to automate sending a text message using python & selenium from https://voice.google.com/about. When I run below code, it picks up the lattest version/ instance of google chrome and works fine. But, when I run it headless mode, it uses an older version of google chrome(guessing from screenshot) and gives TimeoutException() exception. It fails while logging in.

I checked an element id of sign in box in an IE emulator and it appears to be the same.

        url = "https://voice.google.com/about"
        driver.get(url)
        time.sleep(5)
        driver.get_screenshot_as_file('C:\\Drivers\\Q11-0.png')

        # Click on a GET GOOGLE VOICE
        WebDriverWait(driver, 60).until(
            EC.element_to_be_clickable((By.XPATH, '//*[@id="heroToggle"]/button/span'))).click()

        print("Clicked on a get google voice")

        # Click on a WEB
        WebDriverWait(driver, 60).until(
            EC.element_to_be_clickable((By.XPATH, '//*[@id="heroToggle"]/div/button[3]'))).click()
        print("Clicked on a WEB button.")

        driver.get_screenshot_as_file('C:\\Drivers\\Q11-1.png')

        # Enter username and password
        # THIS IS WHERE IT FAILS
        WebDriverWait(driver, 30).until(EC.element_to_be_clickable((By.ID, 'identifierId')))
        email = driver.find_element_by_id('identifierId')
        time.sleep(10)
        email.send_keys('username')
        time.sleep(10)
        nextBtn = driver.find_element_by_xpath('//*[@id="identifierNext"]/content/span')
        nextBtn.click()

        driver.get_screenshot_as_file('C:\\Drivers\\Q11-2.png')


        # Enter password
        password = driver.find_element_by_xpath('//*[@id="password"]/div[1]/div/div[1]/input')
        password.send_keys('password')
        nextBtn = driver.find_element_by_xpath('//*[@id="passwordNext"]/content')
        nextBtn.click()

Screenshot when I run in normal mode,

Screenshot when I run in headless mode,

Drivers are updated properly. I am not sure what I am doing wrong. Any help would really be appreciated.

回答1:

Try to override user-agent, so it wont contains headless tag.

opts = Options()
opts.add_argument("user-agent=User-Agent: Mozilla/5.0 (Windows NT 10.0; Win64; x64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/69.0.3497.100 Safari/537.36")

driver = webdriver.Chrome(chrome_options=opts)
