php - 表单操作忽略了 Google Recaptcha

Question

刚刚集成了 Google Recaptcha。我将此表单用作安全交易站点 (API) 的安全结帐的 POST。

我的挑战是，我有表单 action =

"action="https://securepayments.cardconnect.com/hpp/payment/"

如果我使用事件:

if (isset($_POST['submit'])) {

为了验证::recaptcha::它仍然直接进入表单操作 URL，而不验证 recaptcha。

这里是更多的代码:

    $secret = '-- XX --';
    $response = $_POST['g-recaptcha-response'];
    $remoteip = $_SERVER['REMOTE_ADDR'];

    $url = file_get_contents("https://www.google.com/recaptcha/api/siteverify?secret=$secret&response=$response&remoteip=$remoteip");

    $res = json_decode($unpass, TRUE);

    $result = json_decode($url, TRUE);
    if ($result['success'] == 1) {
        echo $_POST['name'];
        echo $_POST['companyname'];

    }
    else { echo 'you are a robot'; }
}

表单操作 URL 传递 POST/隐藏变量以通过 MID/密码连接以使用 API 验证自己。我不知道如何集成一个解决方案来使用 recaptcha，然后执行表单操作。任何帮助都会很棒!

    function isValid()
          {
              try {

                  $url = 'https://www.google.com/recaptcha/api/siteverify';
                  $data = ['secret'   => 'secret',
                           'response' => $_POST['g-recaptcha-response'],
                           'remoteip' => $_SERVER['REMOTE_ADDR']];

                  $options = [
                      'http' => [
                          'header'  => "Content-type: application/x-www-form-urlencoded\r\n",
                          'method'  => 'POST',
                          'content' => http_build_query($data)
                      ]
                  ];

                  $context  = stream_context_create($options);
                  $result = file_get_contents($url, false, $context);
                  return json_decode($result)->success;
              }
              catch (Exception $e) {
                  return null;
              }
          }

if($_POST && isValid())
 {
 //do stuff
 }
