对于为什么这不起作用感到困惑.提交表单时,我收到错误消息,这意味着我的重新验证失败.
从我的形式：
<div class="g-recaptcha" data-sitekey="(site-key)"></div>
PHP：
if(isset($_POST['g-recaptcha-response'])){
$captcha=$_POST['g-recaptcha-response'];
}
$secretKey = "(secret-key)";
$response = file_get_contents("https://www.google.com/recaptcha/api/siteverify?secret=".$secretKey."&response=".$captcha);
$responseKeys = json_decode($response,true);
if(intval($responseKeys["success"]) === true) {
echo '<h3>Thanks for your message!</h3>';
} else {
echo '<h3>Error</h3>';
}
reCaptcha文档专门指定必须通过POST发送对
https://www.google.com/recaptcha/api/siteverify的请求的参数.您可以使用CURL.
原文链接：https://www.f2er.com/php/136681.html$ch = curl_init();
curl_setopt_array($ch,[
CURLOPT_URL => 'https://www.google.com/recaptcha/api/siteverify',CURLOPT_POST => true,CURLOPT_POSTFIELDS => [
'secret' => $secretKey,'response' => $captcha,'remoteip' => $_SERVER['REMOTE_ADDR']
],CURLOPT_RETURNTRANSFER => true
]);
$output = curl_exec($ch);
curl_close($ch);
$json = json_decode($output);
// check response...
