PHP-使用Google reCaptcha总是显示’incorrect-captcha-sol’

我正在尝试在我的网站上使用Google reCaptcha,并在完成了一些教程之后,在HTML页面上使用了以下方法：

<section class="row" id="Contact">
        <div class="col-full">
             <form method="post" action="contact.php">
                <input name="sender" placeholder="Name" size="30"><br><br>
                <input name="senderEmail" placeholder="Email" size="30"><br><br>
                <textarea rows="10" cols="30" name="message" placeholder="Message"></textarea><br><br>
                <div class="g-recaptcha" data-sitekey="6LdFOQcTAAAAABKsku3bD6Mp3HuGYNDRN1tLlSkw"></div><br>
                <input type="submit" name="submit">
            </form>
        </div>
</section>

在< head>中包含以下内容标签：

    <script src='https://www.google.com/recaptcha/api.js'></script>

该表单将加载以下PHP脚本,如Google’s tutorial所示：

<?php

require_once('recaptchalib.php');

echo "<pre> _POST: =========\n";
print_r($_POST);
echo "\n=========\n</pre>";

$privatekey = "privatekey";
$resp = recaptcha_check_answer ($privatekey,
                             $_SERVER["REMOTE_ADDR"],
                             $_POST["recaptcha_challenge_field"],
                             $_POST["recaptcha_response_field"]);
if (!$resp->is_valid)
{
  die ("The reCAPTCHA wasn't entered correctly. Go back and try it again." .
    "(reCAPTCHA said: " . $resp->error . ")");
}

？>

问题是我总是收到错误不正确的验证码溶胶,并且不明白为什么.我从PHP脚本获得的输出是：

 _POST: =========
Array
(
 [g-recaptcha-response] => 03AHJ_VusLbTZVbhMBH2-cyOdbM81IoG7ShDtTmyVa8e34PbghyKaRYnrb4bbeuPoJXFa-2sD5B-UIOWq_zClya-VOtq8iLHXBkAR0PrElQYiQjKTm2POkjci43-yEaenh1tu_M4vKsjJGswKFlVs6IdlWhdVaMdznLBeutgHjiHRBy7fzAi0It0x5IadwMxAqVpmG7F1gRvUcQmakij4ObTqPUK4lPdc84HkkKmY62uJ45d8DwKSeR2ifRg6wL9JFxpcZkjSp4oIlltin2uCMiBDU58QQQLLKPJuSKcmm-N5p7OEt7E6gc4UZyTLpKrJ-9mMUusvLpixwFHop0e5155vEZssxzu6Zizo-LyB1mX3XOrQ8LEceydssgLvl9gJBC4f9zDBKPQdLmjfxVKdPCXLtUZVNbMDYe7cNL7gsgwJC-hLbZYTh6UV1nUdKnFnkHAACjI7M28hpKWdiyIwcJ5UAzTMPfIllMw

为什么我的POST上没有Recaptcha_challenge_field或recaptcha_response_field字段,我该如何解决？

解决方法:

我用于我的Recaptcha的代码如下：

这放在标题中：

<script src='https://www.google.com/recaptcha/api.js'></script>

这就是您想要的实际recapcha所在的位置：

<div class="g-recaptcha" data-sitekey="PUBLIC_KEY_HERE"></div>

您可以将其添加到div中以更改主题：data-theme =“ theme”

这是PHP脚本：

if(isset($_POST['g-recaptcha-response']))
$captcha=$_POST['g-recaptcha-response'];
if(!$captcha){
    //Captcha hasn't been checked
}
$response=json_decode(file_get_contents("https://www.google.com/recaptcha/api/siteverify?secret=SECRET_KEY_HERE&response=".$captcha."&remoteip=".$_SERVER['REMOTE_ADDR']), true);
if($response['success'] == false){
    //Captcha incorrect
}
else {
    //Success code here
}
