Google reCaptcha json 响应返回 false

Answer 1

你可以按照这个方法尝试一下。 希望对你有帮助。

if(isset($_POST['g-recaptcha-response']) && !empty($_POST['g-recaptcha-response'])){
  $privatekey = "XXXXXXXXXXXXXXXXXXXXXX";
  $captcha = $_POST['g-recaptcha-response'];
  $url = 'https://www.google.com/recaptcha/api/siteverify';
  $data = array(
      'secret' => $privatekey,
      'response' => $captcha,
      'remoteip' => $_SERVER['REMOTE_ADDR']
  );

  $curlConfig = array(
      CURLOPT_URL => $url,
      CURLOPT_POST => true,
      CURLOPT_RETURNTRANSFER => true,
      CURLOPT_POSTFIELDS => $data
  );

  $ch = curl_init();
  curl_setopt_array($ch, $curlConfig);
  $response = curl_exec($ch);
  curl_close($ch);
  $jsonResponse = json_decode($response);
  if ($jsonResponse->success === true) {

  }
  else {
      $errMsg = 'Robot verification failed, please try again.';
    }
} else{

  $errMsg = 'Please click on the reCAPTCHA box.';
}

Answer 2

如果您的验证码经过两次验证，您可能会遇到

timeout-or-duplicate

问题。以附加模式将日志保存在文件中，并检查您是否验证验证码两次。

例如，请检查以下内容：

$verifyResponse = file_get_contents('https://www.google.com/recaptcha/api/siteverify?secret='.$secret.'&response='.$_POST['g-recaptcha-response'])

file_put_contents( "logfile",  $verifyResponse, FILE_APPEND );

现在，检查上面创建的日志文件并尝试检查验证码是否已验证两次。
