please support RECAPTCHA_PROXY

If you require a proxy, add a RECAPTCHA_PROXY setting, for example:

RECAPTCHA_PROXY = 'http://127.0.0.1:8000'

Just a question, why you want to use a proxy only for recaptcha requests?

You can always set the proxy when you run your Django app with environment vars:

$ export HTTP_PROXY="http://localhost:8000"
$ export HTTPS_PROXY="https://localhost:8443"

This is only an example of course!

@kbytesys thank you very much

in china ， we can not access *.google.com ， but www.recaptcha.net

You don't need a proxy, because you need to change the url used by frontend and backend only. For the frontend I've added a configuration key, but I think that it's useful to add this feature also for the server requests.

Reopened because I'm adding the proxy support also on the backend

Link to Google's documentation https://developers.google.com/recaptcha/docs/faq#can-i-use-recaptcha-globally

Can I use reCAPTCHA globally?
Yes, please use "www.recaptcha.net" in your code in circumstances when "www.google.com" is not accessible.

First, replace <script src="https://www.google.com/recaptcha/api.js" async defer></script> with

<script src="https://www.recaptcha.net/recaptcha/api.js" async defer></script>

After that, apply the same to everywhere else that uses "www.google.com/recaptcha/" on your site.

Presumably for web hosting in CN the server side verification URL might need to be changed too?
