Flask-ReCaptcha
The new Google ReCaptcha implementation for Flask without Flask-WTF.
Can also be used as standalone
Install
pip install flask-recaptcha
Usage
Implementation view.py
from flask import Flask
from flask_recaptcha import ReCaptcha
app = Flask(__name__)
recaptcha = ReCaptcha(app=app)
#or
recaptcha = Recaptcha()
recaptcha.init_app(app)
In your template: {{ recaptcha }}
Inside of the form you want to protect, include the tag: {{ recaptcha }}
It will insert the code automatically
<form method="post" action="/submit">
... your field
... your field
{{ recaptcha }}
[submit button]
</form>
Verify the captcha
In the view that's going to validate the captcha
from flask import Flask
from flask_recaptcha import ReCaptcha
app = Flask(__name__)
recaptcha = ReCaptcha(app=app)
@route("/submit", methods=["POST"])
def submit():
if recaptcha.verify():
# SUCCESS
pass
else:
# FAILED
pass
Api
reCaptcha.init(app, site_key, secret_key, is_enabled=True)
reCaptcha.get_code()
Returns the HTML code to implement. But you can use {{ recaptcha }} directly in your template
reCaptcha.verfiy()
Returns bool
In Template
Just include {{ recaptcha }} wherever you want to show the recaptcha
