Question

我在实施recaptcha v2 chekbox时遇到了麻烦。我首先以表单形式实现，它仅在本地服务器上有效。经过多次尝试失败后，我搜索了一些代码，并在教程中原始使用它，并不断出错。网址：https://afrumex.com/google_reCAPTCHA/prueba.html 希望有人可以帮忙。谢谢！

    if(!$captcha){

Answer 1

在尝试以我的形式实现复选框Recaptcha v2一段时间后，我尝试实现不可见的Recaptcha v2，并且此版本运行良好。我不知道这怎么可能！您可以在函数here中看到。

我不知道这与我的ssl证书有关（通过加密）。

这tutorial对我有很大帮助。

感谢您的评论ehacinom！

Answer 2

我遇到了完全相同的问题，并将解决方案发布在INDIRECT下。

我测试过的解决方案是：

$google_url = "https://www.google.com/recaptcha/api/siteverify";
$secret_key = 'YOUR_SECRET_KEY';

$response = $_POST['g-recaptcha-response']; 

$message  = 'Google reCaptcha Test';

if(!empty($response))
{
    $url = $google_url."?secret=".$secret_key."&response=".$response;

    $curl = curl_init();
    curl_setopt($curl, CURLOPT_URL, $url);
    curl_setopt($curl, CURLOPT_RETURNTRANSFER, TRUE);
    curl_setopt($curl, CURLOPT_TIMEOUT, 15);
    curl_setopt($curl, CURLOPT_SSL_VERIFYPEER, TRUE);
    curl_setopt($curl, CURLOPT_SSL_VERIFYHOST, TRUE); 
    $curlData = curl_exec($curl);

    curl_close($curl);

    $res = json_decode($curlData, TRUE);
    if($res['success'] == 'true') 
        $message = "Success!";
    else
        $message = "Enter captcha again!";
}

recaptcha v2没有获得“成功”
