我已经连续几周收到垃圾邮件了。我能够通过表单在我的几个页面上进行一些重新访问，但有一些不起作用。我的一些网站是使用CMS完成的，其他部分是从头开始完成的。所以...有一个名为sign-up.php的页面。这是一个受到最多打击的表单的页面。表单结构有点奇怪。我添加的唯一内容是标记内的php标记和recaptcha脚本。我找到了这个表单发布的文件，但是当我添加google recaptcha告诉我添加的任何内容时，它会崩溃。我试过添加一些简单的行，比如include_once（recaptchalib.php），它仍然会崩溃。

答案 0 :(得分：0)
我建议你看一下EasyCaptchas，因为与recaptcha相比，使用它是非常容易的（使用PHP）？
该代码示例已损坏:)。查询字符串中缺少?。这是一个正确的例子：
<?php
session_start();
if(isset($_POST['captcha'])) {
$captcha = $_POST['captcha'];
$uid = $_SESSION['uid'];
echo file_get_contents("http://www.easycaptchas.com/check.aspx?sessionid=$uid&input=$captcha");
exit();
}
$uid = $_SESSION['uid'] = uniqid();
?>
<form method="post">
<input name="captcha" size="16"/>
<img id="captchaimg" src="http://www.EasyCaptchas.com/<?= $uid; ?>.captcha?" />
<a href="http://www.easycaptchas.com/" onclick="document.getElementById('captchaimg').src+='rf=1';return false;" style="font-size:9px">refresh</a><br />
<!-- Free Captcha provided courtesy of www.EasyCaptchas.com (please do not remove this link) -->
<noscript><a href="http://www.easycaptchas.com/" onclick="return false;" style="display:none">Captcha</a></noscript>
</form>
<script>
console.log(document.getElementById('captchaimg').src);
