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：
@H_502_3@<div class="g-recaptcha" data-sitekey="(site-key)"></div>PHP：
@H_502_3@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($responseKeys["success"]) === true) { echo '<h3>Thanks for your message!</h3>'; } else { echo '<h3>Error</h3>'; }
reCaptcha文档专门指定必须通过POST发送对
https://www.google.com/recaptcha/api/siteverify的请求的参数.您可以使用CURL.
@H_502_3@$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...
