为什么 Google Invisible recaptcha 没有回应？
Why No response from Google Invisible recaptcha?
试图实现Google不可见的recaptcha，但是验证后我没有收到任何回复。
这是我的代码：
invisible_recaptcha.php（表格）
<!doctype html>
<html>
<head>
<meta charset="utf-8">
<title>Recaptcha Demo</title>
<script src="https://www.google.com/recaptcha/api.js" async defer></script>
<script>
function onSubmit(token) {
document.getElementById("i-recaptcha").submit();
}
</script>
</head>
<body>
<!-- FORM GOES HERE -->
<form id='i-recaptcha' action="process_recaptcha.php" method="post">
<label for="fname">First Name*</label><br>
<input type="text" name="fname" id="fname" required autofocus><br><br>
<label for="lname">Last Name*</label><br>
<input type="text" name="lname" id="lname" required><br><br>
<label for="email">Email Address*</label><br>
<input type="email" name="email" id="email" required><br><br>
<button class="g-recaptcha" data-sitekey="XXXXXXmy_site_keyXXXXXXXXX" data-size="invisible" data-callback="onSubmit">
Submit
</button>
</form>
</body>
</html>
process_recaptcha.php（验证验证码）
<?php
// Checks if form has been submitted
if ($_SERVER['REQUEST_METHOD'] == 'POST') {
function post_captcha($user_response) {
$fields_string = '';
$fields = array(
'secret' => 'XXXXXX_my_secret_key_XXXXXXXXX',
'response' => $user_response
);
foreach($fields as $key=>$value)
$fields_string .= $key . '=' . $value . '&';
$fields_string = rtrim($fields_string, '&');
//echo $user_response."<br><br><br><br>". $fields_string;exit;
$ch = curl_init();
curl_setopt($ch, CURLOPT_URL, 'https://www.google.com/recaptcha/api/siteverify');
curl_setopt($ch, CURLOPT_POST, count($fields));
curl_setopt($ch, CURLOPT_POSTFIELDS, $fields_string);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, True);
$result = curl_exec($ch);
curl_close($ch);
return json_decode($result, true);
}
// Call the function post_captcha
$res = post_captcha($_POST['g-recaptcha-response']);
if (!$res['success']) {
// What happens when the reCAPTCHA is not properly set up
echo 'reCAPTCHA error: Check to make sure your keys match the registered domain and are in the correct locations. You may also want to doublecheck your code for typos or syntax errors.';
} else {
// If CAPTCHA is successful...
// Paste mail function or whatever else you want to happen here!
echo '<br><p>CAPTCHA was completed successfully!</p><br>';
}
} ?>
它总是给我这样的信息：
reCAPTCHA 错误：检查以确保您的密钥与注册域匹配并且位于正确的位置。您可能还想仔细检查您的代码是否有拼写错误或语法错误。
请试试这个
try {
//Get google capcha details
if ($site_details['google_captcha_secret_key'] != '') {
$site_key = $site_details['google_captcha_secret_key'];
} else {
$site_key = GOOGLE_CAPTCHA_SECRET_KEY;
}
$url = 'https://www.google.com/recaptcha/api/siteverify';
$data = ['secret' => $site_key,
'response' => $captcha,
'remoteip' => $this->userIpAddress];
$options = [
'http' => [
'header' => "Content-type: application/x-www-form-urlencoded\r\n",
'method' => 'POST',
'content' => http_build_query($data)
]
];
$context = stream_context_create($options);
$result = file_get_contents($url, false, $context);
return json_decode($result)->success;
} catch (Exception $e) {
return null;
}
确保仔细检查代码是否存在语法错误。您缺少站点密钥周围的左引号。你还有一个额外的括号，上面写着 json_decode.
最后，如果您要使用此条件，则无需将其分成两个 PHP 文件：
if ($_SERVER['REQUEST_METHOD'] == 'POST')
所以process_recaptcha.php中的php代码可以嵌入到invisible_recaptcha.php中。然后您必须将表单的操作属性更改为其自身 (invisible_recaptcha.php)。该条件将检查表单是否已提交。如果有，它将处理您的 recaptcha 代码，如果没有，它将跳过它。
