<script src='https://www.google.com/recaptcha/api.js?render=6Le7-FkUAAAAADDSsTVBvpoUB5MkesNKgPVemFf-UD'></script>
</head>
<body>
<script>
// when form is submit
$('form').submit(function() {
// we stoped it
event.preventDefault();
// needs for recaptacha ready
grecaptcha.ready(function() {
// do request for recaptcha token
// response is promise with passed token
grecaptcha.execute('6Le7-FkUAAAAADDSsTVBvpoUB5MkesNKgPVemFf-UD', {action: 'create_comment'}).then(function(token) {
// add token to form
$('form').prepend('<input type="hidden" name="token" value="' + token + '">');
$('form').prepend('<input type="hidden" name="action" value="create_comment">');
// submit form now
$('form').unbind('submit').submit();
});;
});
});
</script>
<form action="verify.php" method="post">
<input type="text" name="name" placeholder="Your name" required >
<input type="email" name="email" placeholder="Your email address" required>
<textarea name="message" placeholder="Type your message here...." required></textarea>
<input type="submit" name="submit" value="SUBMIT">
</form>
</body>
</html>
php
$token = $_POST['token'];
$secret = 'ur secret';
$action = $_POST['action'];
// now you need do a POST requst to google recaptcha server.
// url: https://www.google.com/recaptcha/api/siteverify.
// with data secret:$secret and response:$token
此时，在代码中，您需要向ReCAPTCHA发出发布请求以验证令牌，如此处所述: https://www.google.com/recaptcha/api/siteverify .响应将是一个具有字段"success"(正确/错误)和"action"的json对象 用于比较(==)和得分(数字从0.0-1.0)
At this point in the code, you will need to do a post request to ReCAPTCHA to verify the token, as documented here: https://www.google.com/recaptcha/api/siteverify. The response will be a json object with field "success" (true/false) and "action" for comparison (==) and score (number from 0.0 - 1.0)
https://developers.google.com/recaptcha/docs/v3 #api-response .
您还可以为每个请求指定操作名称(create_post，update_post，create_comment ...)
You can also specify action name for each request (create_post, update_post, create_comment ...)
