I integrated Googles funky ReCaptcha NoCaptcha into a simple html5 form. On localhost it is working, but testing online it always returns the error 'invalid-json'. Here is part of my code:
$secret = 'TEHSEHCRET';
$recaptcha = new \ReCaptcha\ReCaptcha($secret);
$resp = $recaptcha->verify($_POST['g-recaptcha-response'], $_SERVER['REMOTE_ADDR']);
if ($resp->isSuccess()) {
// do some
}
else {
print_r($errors = $resp->getErrorCodes());
}
Returns Array ( [0] => invalid-json )
I googled for some help but found nothing really helpful.
Since the code on- and offline is the same I am really clueless where the problem is coming from. https://developers.google.com/recaptcha/docs/verify says nothing about the error code. Guess the solution is too simple.
I had the same issue and fixed it by using cURL as request method instead POST.
$recaptcha = new \ReCaptcha\ReCaptcha($secret, new \ReCaptcha\RequestMethod\CurlPost());
