安装步骤:
参照原文：http://www.yookoala.idv.hk/en/node/24仅支持Discuz!6.0，修改后，使其在DZX1.0下使用。具体做法：

首先在http://www.google.com/recaptcha申请账号，注册你的网站，获取Public Key和Private Key

到这里下载recaptcha-php-1.11

在/source/include文件夹下新建一个recaptcha文件夹，将下载的recaptchalib.php文件复制到该文件夹内。

打开/source/module/member/member_register.php文件
查找：

^?Download download.php

1	$username = dhtmlspecialchars($username);

在上面添加：

^?Download download.php

// recaptcha hack start
        require_once DISCUZ_ROOT.'./source/include/recaptcha/recaptchalib.php';
        $recaptcha_publickey = '这里替换为你申请到的Public Key';
        $recaptcha_show = recaptcha_get_html($recaptcha_publickey);
// recaptcha hack end

查找：

^?Download download.php

1	$username = addslashes(trim(dstripslashes($username)));

在上面添加：

^?Download download.php

// recaptcha hack start
        require_once DISCUZ_ROOT.'./source/include/recaptcha/recaptchalib.php';
        $recaptcha_privatekey = '这里替换为你申请到Private Key';
        $resp = recaptcha_check_answer ($recaptcha_privatekey,
                  $_SERVER["REMOTE_ADDR"],
                  $_POST["recaptcha_challenge_field"],
                  $_POST["recaptcha_response_field"]);
        if (!$resp->is_valid) {
          // What happens when the CAPTCHA was entered incorrectly
if ($resp->error = 'incorrect-captcha-sol') {
$resp->error = "验证码输入不正确，请按\"刷新\"按钮重新获取验证码并再试一次。";
        }
          showmessage('reCAPTCHA failed. reCAPTCHA said: ' . trim($resp->error));
        }
// recaptcha hack end
