我正在为我的客户集成一个新的Google，我厌倦了我的工作服务器，一切正常工作，但是在客户端服务器上，它的go (!$captcha)部分。

好像Json每次回复错误，我尝试了不同的方法，但都失败了。

这里是我的代码:

ob_start();
require("class.phpmailer.php");
$captcha = $_POST['g-recaptcha-response'];
$mail = new PHPMailer();

$mail->IsSMTP();                        // set mailer to use SMTP
$mail->Host = "";   // specify main and backup server
$mail->SMTPAuth = true;                 // turn on SMTP authentication
$mail->Username = "";  // SMTP username
$mail->Password = "";               // SMTP password


$Name = $_REQUEST['name'];
$Email = $_REQUEST['email'];
$Subject = $_REQUEST['subject'];
$Remarks = $_REQUEST['remarks'];

$mail->From = "";
$mail->FromName = "Vision Pilates Enquiry Form";

$mail->AddAddress("", "Admin");
//$mail->AddAddress("ellen@example.com");                  // name is optional
$mail->AddReplyTo("$Email", "$Name");

$mail->WordWrap = 50;                                 // set word wrap to 50 characters
//$mail->AddAttachment("/var/tmp/file.tar.gz");         // add attachments
//$mail->AddAttachment("/tmp/image.jpg", "new.jpg");    // optional name
//$mail->IsHTML(true);                                  // set email format to HTML

$mail->Subject = "Enquiry from website: $Subject";
$mail->Body    = "<strong>Name:</strong> $Name <br><strong>Email:</strong> $Email <br><strong>Subject:</strong> $Subject <br><strong>Remarks:</strong> $Remarks <br>"; 
$mail->AltBody = "This is the body in plain text for non-HTML mail clients";
if($_SERVER["REQUEST_METHOD"] === "POST") {
    //form submitted

    //check if other form details are correct

    //verify captcha
    if (!$captcha) {
        echo '<h2>Please check the the captcha form.</h2>';
        exit;
    }
    $response = file_get_contents("https://www.google.com/recaptcha/api/siteverify?secret==SecretKey=&response=" . $captcha . "&remoteip=" . $_SERVER['REMOTE_ADDR']);
    if ($response . success == false) {
        echo '<h2>You are spammer ! Get the @$%K out</h2>';
    } else {
        if (!$mail->Send()) {
            header("location: error.htm");
            exit;
        } else {
            header("location: sent.htm");
        }
    }
}

提交后的最终结果是

请查一下卡普查表格。

谢谢

该方法必须根据post的recaptcha文件

API请求网址：https://www.google.com/recaptcha/api/siteverify 方法:员额

function VerifyRecaptcha($g_recaptcha_response) {
    $ch = curl_init();
    $curlConfig = array(
        CURLOPT_URL            => "https://www.google.com/recaptcha/api/siteverify",
        CURLOPT_POST           => true,
        CURLOPT_RETURNTRANSFER => true,
        CURLOPT_POSTFIELDS     => array(
            'secret' => 'your secret goes here <<<<<<<',
            'response' => $g_recaptcha_response,
            'remoteip' => $_SERVER['REMOTE_ADDR']
        )
    );
    curl_setopt_array($ch, $curlConfig);
    if($result = curl_exec($ch)){
        curl_close($ch);
        $response = json_decode($result);
        return $response->success;
    }else{
        var_dump(curl_error($ch)); // this for debug remove after you test it
        return false;
    }
}

那就这样用吧

if(!VerifyRecaptcha($_POST['g-recaptcha-response']))
{
    echo '<h2>Please check the the captcha form.</h2>';
    exit;
}

你做事情的顺序很有趣。在设置其他内容之前检查captcha --如果captcha错误，则不需要PHPMailer实例。

我还怀疑您的URL被破坏了：

$response = file_get_contents("https://www.google.com/recaptcha/api/siteverify?secret==SecretKey=&response=" . $captcha . "&remoteip=" . $_SERVER['REMOTE_ADDR']);

你有一个额外的=在那里，你不会逃避你的对立面。这可能导致无效的URL - recaptcha通常要求两个单词，而空格在URL中无效，所以我建议您这样做：

$response = file_get_contents("https://www.google.com/recaptcha/api/siteverify?secret=SecretKey=&response=" . rawurlencode($captcha) . "&remoteip=" . rawurlencode($_SERVER['REMOTE_ADDR']));
