"missing input response" 错误 recaptcha v3

Question

我正在创建一个表单来发送带有验证码的电子邮件。一切正常，但我注意到 recaptcha v3 只持续了 3 分钟，需要重新设置。从那里开始出现 "missing-input-response" 错误。

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>

class 验证码

<?php

    class Captcha{

    public function getCaptcha($SecretKey){

        $Resposta = file_get_contents("https://www.google.com/recaptcha/api/siteverify?secret=key&response={$SecretKey}");
        $Retorno = json_decode($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;
    }
    }

?>

根据适用于版本 2 的用户评论。您需要为 file_get_contents 函数调用指定其他参数，如果您的网站有 SSL，则设置上下文选项。

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;
    }
}
