Comment contourner Google Recaptcha lors du scraping avec des demandes

Code Python pour demander l'URL:

agent = {"User-Agent":'Mozilla/5.0 (Windows NT 6.3; WOW64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/59.0.3071.115 Safari/537.36'} #using agent to solve the blocking issue
response = requests.get('https://www.naukri.com/jobs-in-andhra-pradesh', headers=agent)
#making the request to the link

Sortie lors de l'impression du html:

<!DOCTYPE html>

<html>
  <head>
    <title>Naukri reCAPTCHA</title> #the title in the actual title of the URL that I am requested for
    <meta name="robots" content="noindex, nofollow">
        <link rel="stylesheet" href="https://static.naukimg.com/s/4/101/c/common_v62.min.css" />      
        <script src="https://www.google.com/recaptcha/api.js" async defer></script>   
    </head>
</html>

En utilisant Google Cache avec un referer empêche ces captcha (n'oubliez pas de ne pas envoyer plus de 2 requêtes en 1 seconde. Vous risquez d'être bloqué:

header = {"user-agent": "Mozilla/5.0 (Windows NT 10.0; Win64; x64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/74.0.3729.169 Safari/537.36" ,'referer':'https://www.google.com/'}
r = requests.get("http://webcache.googleusercontent.com/search?q=cache:www.naukri.com/jobs-in-andhra-pradesh",headers=header)

Cela donne:

>>> r.content
