Forms ReCaptcha 2.0-页面加载时出现错误；缺少输入响应“；

我又回来了。问题就在这里。在实现ReCaptcha 2.0时，我从Github下载了该文件，并完成了所有指示的操作（显然不是这样，否则我就不会有问题）。我的表单会自动加载，并在提交按钮上方显示“缺少输入响应”错误。但是，我可以填写并提交表格，表格会重定向到“谢谢”页面。如果我试图提交表单而不选中复选框，它会给出错误（这是好的），但无论发生什么，错误都存在。我需要做什么？我真的很感激任何帮助

这是我的代码：

<?php
     require('recaptcha-master/src/autoload.php');

    $siteKey = 'MY SITE KEY';
     $secret = 'MY SECRET KEY';


     $recaptcha = new \ReCaptcha\ReCaptcha($secret, new \ReCaptcha\RequestMethod\SocketPost());

    $gRecaptchaResponse = $_POST['g-recaptcha-response']; //google captcha post data
    $remoteIp = $_SERVER['REMOTE_ADDR']; //to get user's ip

    $recaptchaErrors = ''; // blank variable to store error

    $resp = $recaptcha->verify($gRecaptchaResponse, $remoteIp); //method to verify captcha
    if ($resp->isSuccess()) {
       // send mail or insert in db or do whatever you wish to

        $emailbody = 'Name: '.$_POST['name']."\n"
        .'Phone: '.$_POST['phone']."\n"
        .'Email: '.$_POST['email']."\n"
        .'Message: '.$_POST['message'];     
        mail('newsong80@maxxsouth.net', 'More Information', $emailbody);
        echo "<meta http-equiv='refresh' content=\"0; url=thankyou.php\">";


    } else {
       $recaptchaErrors = $resp->getErrorCodes(); // set the error in varible
    }
     ?>

**Here is my form:**  

<form action="contact.php" method="POST" title="Contact us for more information">
                <p><b>Name:<br>
</b>
                    <input name="name" type="text" required id="name" tabindex="1" value="" size="50" maxlength="50"/>
                    <br/> Phone:
                    <br>

                    <input name="phone" type="text" id="phone" tabindex="2" value="" size="50" maxlength="50"/><br/>
                    <b>E-mail:</b><br>
                    <input name="email" type="text" id="email" tabindex="3" value="" size="50" maxlength="25"/><br/>
                    <br>
                    <b>Message:</b><br/>
                    <textarea name="message" cols="60" rows="10" maxlength="150" id="message" tabindex="4"></textarea><br>

                    <br>
                     <div class="g-recaptcha" data-sitekey="MY SITE KEY"></div>
                    <br>
                <?php
                        if ( isset( $recaptchaErrors[ 0 ] ) )
                            echo $recaptchaErrors[ 0 ];

                        ?>
                    <p>&nbsp; </p>
                    <p><input name="submit" type="submit" formmethod="POST" onClick="MM_validateForm('name','','R','phone','','NisNum','email','','RisEmail','message','','R');return document.MM_returnValue" value="Submit">
                    </p>

            </form>

我找到了正在工作的

$ch = curl_init();
curl_setopt($ch, CURLOPT_URL,"https://www.google.com/recaptcha/api/siteverify?");
curl_setopt($ch, CURLOPT_POST, 1);
$campos=array('secret'=>$secreto,'response'=>$TheResponse);
curl_setopt($ch, CURLOPT_POSTFIELDS,$campos);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
$ch_exec = curl_exec($ch);
$respuesta_google = json_decode($ch_exec,true);
var_dump($ch_exec);
var_dump($respuesta_google);
curl_close ($ch);

如果有人能帮忙，我仍然需要一个答案。如果在这个网站上得到了答复，我就找不到了。谢谢
