Question

我已经通过Dreamweaver创建了一个网站，该网站带有一个简单的联系表来发送电子邮件。以前，它没有重新安装并可以正常工作，可以发送电子邮件并正确显示成功/失败消息。我现在使用Recaptcha v2复选框将其重写，但是现在总是收到错误消息“无效的验证码”，并且没有电子邮件。页面显示正确。验证码显示正确，允许您进行选择，然后单击验证按钮，从而显示绿色的勾号。但是，单击“发送”按钮时，它总是失败。

任何帮助表示感谢。

实时网站：https://www.simpleenglish.info/en/contact_us/contact_form.php

我确认站点密钥和秘密密钥以及所有电子邮件地址都是正确的。我已经删除并创建了密钥，并两次通过google admin关联了域，但没有成功。我相信代码是正确的（没有明显的错误）。我在这里或Google网上论坛都没有找到任何类似的问题来指明我的方向。我不知道还能去哪里。

Answer 1

您的Recaptcha的div标签未正确关闭。查看页面源代码，您将在表格行中看到它。

<tr><td>Spam Check:</td><td><div class="g-recaptcha" data-sitekey="6Lc8OZ8UAAAAABUosvouUbamfotW9Pp-9ioRIEOZ"></td></tr>

Answer 2

因为我使用类，所以将其放入函数中。 Google希望该方法为POST。您可以通过设置file_get_contents选项来使用stream_context_create。

其余的内容很容易解释，$secretkey是您的身份验证密钥，$captcha是您的$_POST['g-recaptcha-response']

https://www.php.net/manual/en/function.stream-context-create.php

function checkRecaptcha( $secretkey , $captcha ){

    $url = 'https://www.google.com/recaptcha/api/siteverify';
    $data = [
        'secret' => $secretkey , 
        'response' => $captcha ,
        'remoteip' => $_SERVER['REMOTE_ADDR'] ,
    ];
    $options = [
        'http' => [
          'header'  => "Content-type: application/x-www-form-urlencoded\r\n",
          'method'  => 'POST',
          'content' => http_build_query( $data )
          ]
    ];
    $context  = stream_context_create( $options );
    $contents = file_get_contents( $url , false , $context );
    $response = json_decode( $contents , true ); //convert to assoc array
    // if you want to use objects, remove true from json decode and then use $response->success
    if( ! $response["success"] ) { 
        return false;
    }
    return true;
}

然后您可以像这样使用它：

<?php

function checkRecaptcha( $secretkey , $captcha ){

    $url = 'https://www.google.com/recaptcha/api/siteverify';
    $data = [
        'secret' => $secretkey , 
        'response' => $captcha ,
        'remoteip' => $_SERVER['REMOTE_ADDR'] ,
    ];
    $options = [
        'http' => [
            'header'  => "Content-type: application/x-www-form-urlencoded\r\n",
            'method'  => 'POST',
            'content' => http_build_query( $data )
            ]
    ];
    $context  = stream_context_create( $options );
    $contents = file_get_contents( $url , false , $context );
    $response = json_decode( $contents , true ); //convert to assoc array
    // if you want to use objects, remove true from json decode and then use $response->success
    if( ! $response["success"] ) { 
        return false;
    }
    return true;
}

if( isset($_POST['submit'] ) ) {

    $secretkey = "XXX Correct key here XXX";

    if( ! checkRecaptcha( $secretkey , $_POST['g-recaptcha-response'] ) ) {

        //only set variables if passes recaptcha

        //validate email address
        if ( ! filter_var( $_POST['senderemail'] , FILTER_VALIDATE_EMAIL)) {
            echo "Please provide a valid email";
            die();
        }

        //ensure user doesn't post HTML
        $user_name = strip_tags ( $_POST['sendername'] ); 
        $user_context = strip_tags ( $_POST['sendercontext'] );
        $user_message = strip_tags ( $_POST['sendermessage'] );

        $email_body = "Name: $user_name.\n"."Email: {$_POST['senderemail']}.\n"."Context: $user_context.\n"."Message: $user_message.\n";

        $header = "From: bla@simpleenglish.info \r\n";
        $header .= "Reply-To: {$_POST['senderemail']} \r\n";

        mail( 'bla@simpleenglish.com' , 'Simple English Contact' , $email_body , $header );
        echo "Message sent successfully";

    }else{

        echo "Invalid Captcha. Please try again.";

    }
}

?>
