Php google recaptcha和表单不起作用

我试图在我的网站上实现google recaptcha。但由于某些原因，它不起作用。表格未提交。此外，验证码重新检查错误不起作用。我还插入了我的google recaptcha密钥

我在网上找到了验证码 我做错了什么

<?php


if ( isset( $_POST[ 'g-recaptcha-response' ] ) && $_POST[ 'g-recaptcha-response' ] ) {
    var_dump( $_POST );
    $secret = "my secret key";
    $ip = $_SERVER[ 'REMOTE_ADDR' ];
    $captcha = $_POST[ 'g-recaptcha-response' ];
    $rsp = file_get_contents( "https://www.google.com/recaptcha/api/siteverify?secret=$secret&response=$captcha&remoteip$ip" );
    var_dump( $rsp );
    $arr = json_decode( $rsp, TRUE );

    if ( $arr[ 'success' ] ) {


        $address = "myemail@yahoo.com";


        $CompanyName = $_POST[ 'CompanyName' ];
        $ContactName = $_POST[ 'ContactName' ];
        $City = $_POST[ 'City' ];
        $State = $_POST[ 'State' ];
        $Phone = $_POST[ 'Phone' ];
        $Email = $_POST[ 'Email' ];
        $FromFind = $_POST[ 'FromFind' ];
        $Comments = $_POST[ 'Comments' ];
        $Page = $_POST[ 'Page' ];

        $headers = "From: $Email";
        $headers .= "Reply-To: $Email";
        $headers .= "MIME-Version: 1.0";
        $headers .= "Content-type: text/plain; charset=utf-8";
        $headers .= "Content-Transfer-Encoding: quoted-printable";

        $e_subject = 'MicroShred.com Form Contact by ' . $ContactName . '.';
        // Email message:
        $msg = "You have been contacted by $ContactName, in $City $State, through your $Page. Their message is as follows:";
        $msg .= "$Comments";
        $msg .= "You can contact $ContactName via email, $Email or via phone $Phone.";
        $msg .= "-------------------------------------------------------------------------------------------";
        $msg .= "This message was sent to you via your website Contact Form";
        $msg = wordwrap( $msg, 70 );

        if ( mail( $address, $e_subject, $msg, $headers ) ) {

            echo "<fieldset>";
            echo "<div class=\"notification success closeable\">";
            echo "<p><strong>Email Sent Successfully.</strong><br />";
            echo "Thank you $name, your message has been submitted to us.</p>";
            echo "</div>";
            echo "</fieldset>";

        } else {

            echo 'ERROR!';

        }




    } else {
        echo ' please make sure that you have checked the captcha';
    }


}


?>

这是表格

*=必填字段

您的web服务器可能正在阻止您的文件获取内容命令。通过检查“allow\u url\u fopen”指令是否关闭，可以在phpinfo详细信息中验证这一点。如果是，则文件获取内容将无法工作

在过去遇到过这个问题，我不得不使用curl来让验证过程正常工作，作为文件内容的替代

$ch = curl_init();
curl_setopt_array($ch, [
    CURLOPT_URL => 'https://www.google.com/recaptcha/api/siteverify',
    CURLOPT_POST => true,
    CURLOPT_POSTFIELDS => [
        'secret' => $secret,
        'response' => $captcha,
        'remoteip' => $ip
        ],
    CURLOPT_RETURNTRANSFER => true
    ]);

$output = curl_exec($ch);
curl_close($ch);

$arr = json_decode($output);

if ( $arr->success !== true ) {
    //Submission errored out
    }
else {
    //Send Email
    }

如果表单未提交，则显示表单可能会很有用。另外，请考虑不包括私钥。这将是明智的改变关键，因为一些机器人或用户可能已经刮了它，现在可以使用它了。谢谢
