我已经成功将ReCaptcha 2.0应用到我的网站上。但是,只有在我不使用AJAX并允许表单“自然地”提交时才能正常工作。
我希望能够使用验证码提交表单,并通过成功提示而无需刷新页面来提醒用户。
我尝试了下面的代码,但似乎服务器没有收到用户的响应:
HTML:
<form class="form" action="javascript:void(0)" novalidate>
<!-- all the inputs... -->
<!-- captcha -->
<div class="input-group">
<div class="g-recaptcha" data-sitekey="6LdOPgYTAAAAAE3ltWQGar80KUavaR-JblgPZjDI"></div>
</div>
<div class="errors" id="errors" style="display: none"></div>
<div class="input-group">
<input type="button" value="Send" class="btn-default right" id="submit">
<div class="clear"></div>
</div>
</form>
JS:
$('#submit').click(function(e) {
console.log('clicked submit'); // --> works
var $errors = $('#errors'),
$status = $('#status'),
name = $('#name').val().replace(/<|>/g, ""), // prevent xss
email = $('#email').val().replace(/<|>/g, ""),
msg = $('#message').val().replace(/<|>/g, "");
if (name == '' || email == '' || msg == '') {
valid = false;
errors = "All fields are required.";
}
// pretty sure the problem is here
console.log('captcha response: ' + grecaptcha.getResponse()); // --> captcha response:
if (!errors) {
// hide the errors
$errors.slideUp();
// ajax to the php file to send the mail
$.ajax({
type: "POST",
url: "http://orenurbach.com/assets/sendmail.php",
data: "email=" + email + "&name=" + name + "&msg=" + msg + "&g-recaptcha-response=" + grecaptcha.getResponse()
}).done(function(status) {
if (status == "ok") {
// slide down the "ok" message to the user
$status.text('Thanks! Your message has been sent, and I will contact you soon.');
$status.slideDown();
// clear the form fields
$('#name').val('');
$('#email').val('');
$('#message').val('');
}
});
} else {
$errors.text(errors);
$errors.slideDown();
}
});
PHP:
<?php
// assemble the message from the POST fields
// getting the captcha
$captcha = '';
if (isset($_POST['g-recaptcha-response']))
$captcha = $_POST['g-recaptcha-response'];
echo 'captcha: '.$captcha;
if (!$captcha)
echo 'The captcha has not been checked.';
// handling the captcha and checking if it's ok
$secret = 'MY_SECRET';
$response = json_decode(file_get_contents("https://www.google.com/recaptcha/api/siteverify?secret=".$secret."&response=".$captcha."&remoteip=".$_SERVER['REMOTE_ADDR']), true);
var_dump($response);
// if the captcha is cleared with google, send the mail and echo ok.
if ($response['success'] != false) {
// send the actual mail
@mail($email_to, $subject, $finalMsg);
// the echo goes back to the ajax, so the user can know if everything is ok
echo 'ok';
} else {
echo 'not ok';
}
?>
PHP页面中的结果:
captcha: The captcha has not been checked.array(2) { ["success"]=> bool(false) ["error-codes"]=> array(1) { [0]=> string(22) "missing-input-response" } } not ok
底线是,我如何手动获取输入响应而不让它自动与其余的POST数据一起发送?
grecaptcha.getResponse()
,你得到了什么?是空的吗? - Samurai
