我有什么可能是一个非常基本的问题，但对 PHP 和表单创建很陌生，所以希望有人能帮助我。

尽管使用了蜜罐方法，但我们的网站上仍有垃圾邮件机器人不断提交单字段电子邮件表单，因此我希望使用 Google 的 Invisible reCaptcha 来对抗这种情况。

我正在按照这个有用的指南中的说明进行操作：https ://www.pinnacleinternet.com/installing-invisible-recaptcha/但是我遇到困难的是，在结果成功之后，我想采取通过表单提交的电子邮件地址，然后将其发布到第三方服务器（在本例中为我们的营销自动化工具 Pardot）。

这是 Invisible reCaptcha 代码：

前端

<script>
function captchaSubmit(data) {
document.getElementsByClassName("invisible-recaptcha").submit();
}
</script>  

<form action="utils/recaptcha.php" method="post" class="pardot-email-form-handler invisible-recaptcha" novalidate>    
        <input class="one-field-pardot-form-handler" maxlength="80" name="email" size="20" type="email" placeholder="Enter Email Address" required="required" />
        <div style="position:absolute; left:-9999px; top: -9999px;">
          <label for="pardot_extra_field">Comments</label>
          <input type="text" id="pardot_extra_field" name="pardot_extra_field">
        </div>

        <button class="g-recaptcha" data-sitekey="anonymous" data-callback="captchaSubmit" type="submit" name="captchaSubmit">Submit</button>
    </form>

后端：

<?php
    // reCaptcha info
    $secret = "anonymous";
    $remoteip = $_SERVER["REMOTE_ADDR"];
    $url = "https://www.google.com/recaptcha/api/siteverify";

    // Form info
    $email = $_POST["email"];
    $response = $_POST["g-recaptcha-response"];

    // Curl Request
    $curl = curl_init();
    curl_setopt($curl, CURLOPT_URL, $url);
    curl_setopt($curl, CURLOPT_POST, true);
    curl_setopt($curl, CURLOPT_RETURNTRANSFER, 1);
    curl_setopt($curl, CURLOPT_POSTFIELDS, array(
        'secret' => $secret,
        'response' => $response,
        'remoteip' => $remoteip
        ));
    $curlData = curl_exec($curl);
    curl_close($curl);

    // Parse data
    $recaptcha = json_decode($curlData, true);
    if ($recaptcha["success"])
        echo "Success!";
    else
        echo "Failure!";
?>

我之前曾使用下面的代码发布到 Pardot，但现在不清楚如何做到这一点，因为最初的帖子是发给 Google 而不是 Pardot。在 Invisible reCaptcha 成功确认后，我将如何发布到 Pardot？

<div class="nav-email-form">    
<form action="https://go.pardot.com/l/43312/2017-10-24/7dnr3n" method="post" class="pardot-email-form-handler" novalidate>

<input class="one-field-pardot-form-handler" maxlength="80" name="email" size="20" type="email" placeholder="Enter Email Address" required="required" />
<div style="position:absolute; left:-9999px; top: -9999px;">
  <label for="pardot_extra_field">Comments</label>
  <input type="text" id="pardot_extra_field" name="pardot_extra_field">
</div>

<button type="submit" name="submit">Submit</button>
</form>

由于您curl最初已经在使用来处理验证码，因此您可能应该在响应POST时使用 curl 向 Pardot 发出请求success。你也许可以这样尝试 - 顺便说一句，未经测试

function curl( $url=NULL, $options=NULL ){
    /*
        Download a copy of cacert.pem from
        https://curl.haxx.se/docs/caextract.html

        and then edit below as appropriate
    */
    $cacert='c:/wwwroot/cacert.pem';    #<-------- edit to suit own environment

    $res=array(
        'response'  =>  NULL,
        'info'      =>  array( 'http_code' => 100 ),
        'headers'   =>  NULL,
        'errors'    =>  NULL
    );
    if( is_null( $url ) ) return (object)$res;
    /* Initialise curl request object */
    $curl=curl_init();
    if( parse_url( $url,PHP_URL_SCHEME )=='https' ){
        curl_setopt( $curl, CURLOPT_SSL_VERIFYPEER, true );
        curl_setopt( $curl, CURLOPT_SSL_VERIFYHOST, 2 );
        curl_setopt( $curl, CURLOPT_CAINFO, $cacert );
    }
    /* Define standard options */
    curl_setopt( $curl, CURLOPT_URL,trim( $url ) );
    curl_setopt( $curl, CURLOPT_AUTOREFERER, true );
    curl_setopt( $curl, CURLOPT_FOLLOWLOCATION, true );

    curl_setopt( $curl, CURLOPT_ENCODING, '' );
    /* Assign runtime parameters as options */
    if( isset( $options ) && is_array( $options ) ){
        foreach( $options as $param => $value ) curl_setopt( $curl, $param, $value );
    }
    /* Execute the request and store responses */
    $res=(object)array(
        'response'  =>  curl_exec( $curl ),
        'info'      =>  (object)curl_getinfo( $curl ),
        'errors'    =>  curl_error( $curl )
    );
    curl_close( $curl );
    return $res;
}

/*

$url='https://www.google.com/recaptcha/api/siteverify';
$params=array(
    'secret'    => $secret,
    'response'  => $_POST['g-recaptcha-response'],
    'remoteip'  => $_SERVER['REMOTE_ADDR']
);
$options=array(
    CURLOPT_POST        =>  true,
    CURLOPT_POSTFIELDS  =>  $params
);
$result=curl( $url, $options );
if( $result->info->http_code==200 ){

    $json=json_decode( $result->response );
    $status=$json->success;
    if( $status ){

        /*

        $_POST['pardot_extra_field']='';
        $_POST['submit']='';

        /* no need to send this field */
        unset( $_POST['g-recaptcha-response'] );

        /* this needs a value - but from where? */
        #$_POST['email']='GERONIMO@EXAMPLE.COM';

以下是我最终对后端代码所做的事情。需要更好的成功和错误处理，我只将 SSL_VERIFYPEER 设置为 false，因为我是在本地环境中设置它，但它已经过测试并成功发布到 Pardot：

<!DOCTYPE html>
<html lang="en">
<head>
    <meta charset="utf-8">
    <title>Results</title>
</head>
<body>
    <p>Thank you for entering the form.</p>

    <?php
        // reCaptcha info
        $secret = "anonymous";
        $remoteip = $_SERVER["REMOTE_ADDR"];
        $url = "https://www.google.com/recaptcha/api/siteverify";

        // Form info
        $email = $_POST["email"];
        $response = $_POST["g-recaptcha-response"];

        // Curl Request
        $curl = curl_init();
        curl_setopt($curl, CURLOPT_URL, $url);
        curl_setopt($curl, CURLOPT_POST, true);
        curl_setopt($curl, CURLOPT_SSL_VERIFYPEER, false);
        curl_setopt($curl, CURLOPT_RETURNTRANSFER, 1);
        curl_setopt($curl, CURLOPT_POSTFIELDS, array(
            'secret' => $secret,
            'response' => $response,
            'remoteip' => $remoteip
            ));
        $curlData = curl_exec($curl);
        curl_close($curl);

        // Parse data
        $recaptcha = json_decode($curlData, true);

        if ($recaptcha["success"]) {
            echo "Success!";

            $pardotPost ='email='. $_POST["email"];
            $curl_handle = curl_init();
            $url = "anonymous";
            curl_setopt ($curl_handle, CURLOPT_URL,$url);
            curl_setopt($curl_handle, CURLOPT_POST, true);
            curl_setopt ($curl_handle, CURLOPT_RETURNTRANSFER, 1);
            curl_setopt ($curl_handle, CURLOPT_POSTFIELDS, $pardotPost);
            curl_setopt( $curl_handle, CURLOPT_SSL_VERIFYPEER, false ); 
            $result = curl_exec ($curl_handle);
            curl_close ($curl_handle); 
        }   

        else {
            echo "Failure!";
        }
    ?>
</body>
</html>
