Django reCAPTCHA Integration Django.How

1. Get a reCAPTCHA Account

• Visit google.com/recaptcha Create Account
• Choose V3
• Add domains
• Get keys and save them in settings.py

# reCAPTCHA
GOOGLE_RECAPTCHA_SITE_KEY = '6LfHCw0pAAasddasdasd'
GOOGLE_RECAPTCHA_SECRET_KEY = '6LfHCw0pasdasdasdasdas'
  

2. Create a reusable function to validate reCAPTCHA

install the request packages

pip install requests
  

We choose lib.py to create our reusable function

from django.conf import settings
import requests

def validate_recaptcha(request):
''' reCAPTCHA validation '''
recaptcha_response = request.POST.get('g-recaptcha-response')
data = {
'secret': settings.GOOGLE_RECAPTCHA_SECRET_KEY,
'response': recaptcha_response
}
r = requests.post('https://www.google.com/recaptcha/api/siteverify', data=data)
result = r.json()

return result

On any template, you want to use reCAPTCHA, add the reCAPTCHA field and script to the desired form
</p> <form method="post" id="contactform"> {% csrf_token %}<br /> …<br /> <script src='https://www.google.com/recaptcha/api.js?render=your_site_key'></script><br /> <input type="hidden" id="g-recaptcha-response" name="g-recaptcha-response"><br /> …<br /> <button type="submit">Submit</button><br /> </form> <p>

to the view

from .lib import validate_recaptcha

def my_view(request):
  if request.method == 'POST':
    # do your form validation
    if validate_recaptcha(request):
      #Save
    else:
      print('wrong recaptcha')
