Can I bypass Recaptcha in the form

[Nikita Chavan]

Hi,

I am trying to automate form and stuck at Recaptcha. I could able to tick the checkbox but how should I bypass the image validating?

Is that doable? 

In Advance: Thanks for your help!

In the test version of what you are automating you can use 

https://cloud.google.com/recaptcha/docs/quickstart-app.

You can't. Their purpose is to determine if you are human.

If this is your own site, disable CAPTCHA in your test environment.

Thanks a lot all. I will try it on test environment instead of prod by disabling recaptcha.

Actually, you can bypass recaptcha using a third party service called 2Captcha, but it's a paid service. I use and recommend this service, but in some cases (callback recaptcha), you'll need to implement some tools to set the response like:

log = LoggerFactory.get_stream_logger('CaptchaSolver')

FLATTEN_OBJECT_SCRIPT = 'window._flattenObject=function(e,t=2,n=!0){const c=e=>e&&"object"==typeof e,o=e=>e&&e instanceof HTMLElement;let f={};for(let r=0;r<t;r++)e=Object.keys(f).length?f:e,Object.keys(e).forEach(t=>{n&&o(e[t])||(c(e[t])?Object.keys(e[t]).forEach(r=>{if(n&&o(e[t][r]))return;const b=c(e[t][r])?`obj_${t}_${r}`:`${r}`;f[b]=e[t][r]}):f[t]=e[t])});return f};'
DATA_RECAPTCHA_SCRIPT = 'return window._flattenObject(window.___grecaptcha_cfg.clients[0]);'
SET_RESPONSE_SCRIPT = 'arguments[0].innerHTML = arguments[1];'
CALLBACK_SCRIPT = 'var flat = window._flattenObject(window.___grecaptcha_cfg.clients[0]); if (flat.callback) {flat.callback.call(window, arguments[0]);}'


class CaptchaSolver:
def __init__(self) -> None:
self.solver = twocaptcha.TwoCaptcha(**{
'apiKey': os.environ.get('TWO_CAPTCHA_KEY', default='<YOUR_API_KEY>'),
'defaultTimeout': 120,
'recaptchaTimeout': 600,
'pollingInterval': 10,
})

def solve_captcha(self, driver: WebDriver):
if not DriverUtils.is_headless(driver):
log.info('solving the captcha using the screen')
return input('Solved?')
log.info('trying to solve captcha')
driver.execute_script(FLATTEN_OBJECT_SCRIPT)

response: Dict[str, Any] = self.solver.recaptcha(
sitekey=driver.execute_script(DATA_RECAPTCHA_SCRIPT).get('sitekey'),
url=driver.current_url
)

log.info(f'RECAPTCHA RESPONSE: {response}')

g_captcha = DriverUtils.find_by_tag(driver, 'textarea')
driver.execute_script(SET_RESPONSE_SCRIPT, g_captcha, response.get('code'))

try:
driver.execute_script(CALLBACK_SCRIPT, response.get('code'))
except Exception:
...

log.info('solved captcha')
