“缺少輸入響應”錯誤重新獲取v3

Question

我正在創建一個表單，用recaptcha發送電子郵件。 一切都很完美，但我注意到recaptcha v3只持續了3分鍾，需要重置。 從那里開始給出“缺失 - 輸入 - 響應”錯誤。

的index.php

<script>
  grecaptcha.ready(function() {
      grecaptcha.execute('key', {action: 'homepage'}).then(function(token) {
         document.getElementById('g-recaptcha-response').value=token;
      }); 
  });
  </script>

  <script>
    var callback = function() {
      grecaptcha.render('id-of-render-element', {
         'sitekey': 'key',
         'expired-callback': expCallback
       });
   };
   var expCallback = function() {
      alert("Your recatpcha has expired, please verify again ...");
      setInterval(function(){ grecaptcha.reset(); }, 5 * 60 * 1000 ); 
   };
  </script>

 <div id="id-of-render-element"></div>
<script src="https://www.google.com/recaptcha/api.js?onload=callback&render=explicit" async defer></script>

  }else{

  }
  return $EnviaMail;
    }
    }

Answer 1

根據用於版本2的用戶注釋。您需要為file_get_contents函數調用指定其他參數，如果您的站點具有SSL，則設置上下文選項。

class Captcha{        
    public function getCaptcha($SecretKey){
        if($SecretKey){
            // Input data
            $secret = 'SECRET_KEY';
            $response = $SecretKey;
            $remoteip = $_SERVER['REMOTE_ADDR'];

            $url = "https://www.google.com/recaptcha/api/siteverify";

            $post_data = http_build_query(
                array(
                    'secret' => $secret,
                    'response' => $response,
                    'remoteip' => $remoteip
                )
            );
            $options=array(
                // If site has SSL then
                'ssl'=>array(
                    // In my case its /etc/ssl/certs/cacert.pem
                    'cafile'            => '/path/to/cacert.pem',
                    'verify_peer'       => true,
                    'verify_peer_name'  => true,
                ),
                'http' =>array(
                        'method'  => 'POST',
                        'header'  => 'Content-type: application/x-www-form-urlencoded',
                        'content' => $post_data
                )
            );
            $context  = stream_context_create( $options );
            $Resposta = file_get_contents( $url, false, $context );
            $Retorno = json_decode($Resposta);
            return $Retorno;
        }
    }
    public function returnCaptcha(){
        echo "entrou calss_captcha";
        $EnviaMail = False;
        $ObjCaptcha = new Captcha();
        $Retorno=$ObjCaptcha->getCaptcha($_POST['g-recaptcha-response']);
        var_dump($Retorno);
        if($Retorno->success == true && $Retorno->score > 0.5){
            $EnviaMail = True;
        }else{
            $EnviaMail = False;
        }
        return $EnviaMail;
    }
}
