然後在form的action程式裏面貼上利用這個function ，如果false就不給登入，就能夠啦~

若是已註冊過，想查詢自己的公私鑰:
https://www.google.com/recaptcha/admin#list
還沒註冊過的，下面三步調設立建設Google reCAPTCHA~

前去 Google機械人官網，點選右上的「Admin console」按鈕。

STEP I

複製代碼

<script src="https://www.google.com/recaptcha/api.js?onload=onloadCallback2&render=explicit" async></script>
<script>
var onloadCallback2 = function() {
grecaptcha.render("recaptcha_box2", {
/* Change Your sitekey */
"sitekey": "公鑰",
"callback": callback2
});
};
function callback2() {
/* 這裡可履行提交表單的動作
alert("恭喜你驗證成功");
*/
document.getElementById("submit2").disabled = false;
document.getElementById("submit2").classList.remove('au-btn--gray');
document.getElementById("submit2").classList.add('au-btn--yellow');
}
</script>

複製代碼

// GOOGLE RECAPTHA
$data['secret'] = '私鑰';
$data['response'] = $_POST['g-recaptcha-response'];
$ch = curl_init();
// 使用CURL驗證
curl_setopt($ch,CURLOPT_SSL_VERIFYHOST,0);
curl_setopt($ch,CURLOPT_SSL_VERIFYPEER,0);
curl_setopt($ch,CURLOPT_RETURNTRANSFER, true);
curl_setopt($ch, CURLOPT_URL, 'https://www.google.com/recaptcha/api/siteverify');
curl_setopt($ch, CURLOPT_POST, true);
curl_setopt($ch, CURLOPT_POSTFIELDS, http_build_query($data));
$result = curl_exec($ch);
curl_close($ch);
// 解密
$result = json_decode($result, true);
// 搜檢是不是經由過程驗證
if ( ! isset($result['success']) || ! $result['success']) {
// 驗證失敗
echo "<script>alert('驗證碼機械人失敗!');history.go(-1);</script>";
exit;
}
