编辑:我正在使用 reCaptcha 2.0，我不应该使用 recaptchalib.php 吗？
现场演示 http://josiahbertoli.com/
提交表单时出现以下错误(忽略输入字段的空白值)(带有调试代码):
错误
_POST: =========
Array
(
[first_name] =>
[last_name] =>
[email] =>
[subject] =>
[comments] =>
[g-recaptcha-response] => big-long-value
)
=========
reCAPTCHA 未正确输入。返回并再试一次。(reCAPTCHA 说:)`
我的网页是如何设置的:
HTML
<form id="query-form" action="wp-content/themes/portfolio/submit-form.php" method="post" name="myForm">
<input id="first_name" name="first_name" size="35" type="text" placeholder="e.g. John" />
<input id="last_name" name="last_name" size="35" type="text" placeholder="e.g. Smith" />
<input id="email" name="email" size="35" type="text" placeholder="e.g. <a href="https://stackoverflow.com/cdn-cgi/l/email-protection" class="__cf_email__" data-cfemail="6e0b160f031e020b2e0a01030f0700400d0103" rel="noreferrer noopener nofollow">[email protected]</a>" />
<input id="subject" name="subject" size="35" type="text" placeholder="e.g. Feedback" />
<textarea id="comments" name="comments"></textarea>
<div class="g-recaptcha" data-sitekey="6Le8WxcTAAAAAGqymotU9wtOBFEmWgjM3j2kqTcB"></div>
<input type="submit" value="Submit" />
</form>
Submit使用POST方法调用actionsubmit-form.php，如下
PHP
<?php
require_once('recaptchalib.php');
$privatekey = "the-key-that-i-put-in";
echo "<pre> _POST: =========\n"; print_r($_POST); echo "\n=========\n</pre>";
$resp = recaptcha_check_answer ($privatekey, $_SERVER["REMOTE_ADDR"],
$_POST["recaptcha_challenge_field"],
$_POST["recaptcha_response_field"]);
$resp = null;
if (!$resp->is_valid) {
// What happens when the CAPTCHA was entered incorrectly
die ("The reCAPTCHA wasn't entered correctly. Go back and try it again." . "(reCAPTCHA said: " . $resp->error . ")"); }
else {
// Your code here to handle a successful verification
include '../../../../process.php';
}
?>
感谢您的回复，我很感激。
最佳答案
要显示 reCAPTCHA 小部件，您不需要任何库文件，只需包含必要的 JavaScript 资源，如下所示:
<html>
<head>
<title>reCAPTCHA demo: Simple page</title>
<script src="https://www.google.com/recaptcha/api.js" async defer></script>
</head>
<body>
<form action="?" method="POST">
<div class="g-recaptcha" data-sitekey="your_site_key"></div>
<br/>
<input type="submit" value="Submit">
</form>
</body>
</html>
引用资料如下:
现在是您的用户的响应。由于您使用的是 Google reCAPTCHA V2，因此您应该使用 POST 参数 g-recaptcha-response 获取用户的响应。
引用资料如下:
所以你的代码应该是这样的:
<?php
if(isset($_POST['g-recaptcha-response']) && !empty($_POST['g-recaptcha-response'])){
$privatekey = "YOUR_PRIVATE_KEY";
//get verified response data
$param = "https://www.google.com/recaptcha/api/siteverify?secret=".$privatekey."&response=".$_POST['g-recaptcha-response'];
$verifyResponse = file_get_contents($param);
$responseData = json_decode($verifyResponse);
if($responseData->success){
// success
echo "success";
}else{
// failure
echo "failure";
}
}else{
// user didn't enter reCAPTCHA
echo "The reCAPTCHA wasn't entered correctly. Go back and try it again.";
}
?>
