在Grav中使用hCaptcha的Zammad Feedbackform

Question

我正在用Grav创建一个网站。我使用Zammad作为票务系统，并希望在页面上包含反馈表单。为此，我使用了Zammad "https://admin-docs.zammad.org/en/latest/channels/form.html"“的应用程序接口。这就像它一样工作。可以通过表单创建新的票证。现在我想添加一个机器人保护。为此，我选择了hCaptcha。https://docs.hcaptcha.com/ (谷歌reCaptcha可以毫不费力地使用现成的插件”表单“，但我不想使用谷歌reCaptcha)。我也已经开始为hCaptcha编写一个插件，但我找不到正确的Grav入口。

我当前的代码：

function onFormProcessed(Event $event){

    if(is_entered_data_valid()) {
        if(isset($_POST['h-captcha-response']) && !empty($_POST['h-captcha-response'])){
            $secret = "0x0000000000000000000000000000000000000000";
            $remote_address = $_SERVER['REMOTE_ADDR'];
            $verify_url = "https://hcaptcha.com/siteverify?secret=".$secret."&response=".$_POST['h-captcha-response']."&remoteip=".$remote_address;
                // This is hcaptcha url
                $response = file_get_contents($verify_url); # Get token from post data with key 'h-captcha-response' and Make a POST request with data payload to hCaptcha API endpoint
                $responseData = json_decode($response);
                $success_msg="";
                $err_msg="";
                if($responseData->success){
                    $success_msg = "You can process your login functionality";
                }else{
                    $err_msg =  "Something went wrong while hCaptcha Validation. Please try again after sometime.";
                }
            }else{
                $err_msg =  "Please fill all the required fields";
            }
        } else {
            // Server side validation failed
            $error_output = "Please fill all the required fields";
        }
        // Get the response and pass it into your ajax as a response.
        $return_msg = array(
            'error'     =>  $err_msg,
            'success'   =>  $success_msg
        );
        echo json_encode($return_msg);

    }

此函数必须在提交表单时执行

如果你走对了方向，onFormProcessed就是你需要使用的事件。你可以从Grav的表单插件中学习。但是，您需要为您的插件定义一个特定的表单操作，否则您的代码将为站点上的所有表单运行，无论这些表单是否使用您的验证码。

假设您的表单操作是hcaptcha

    public function onFormProcessed(Event $event): void
    {
        $form = $event['form'];
        $action = $event['action'];

        switch ($action) {
            case 'hcaptcha':
                // If captcha validation fails, stop the form processing.
                if ($validation_fails) {
                    $message = "Please solve the captcha!";

                    $this->grav->fireEvent('onFormValidationError', new Event([
                        'form' => $form,
                        'message' => $message
                    ]));

                    $event->stopPropagation();

                    return;
                 }
