Question

我正在尝试使用Google ReCaptcha验证给定的输入，并在必要时将错误消息发送到字符串中。目前，我有以下形式的问题块：

//Google ReCaptcha
if(isset($_POST['g-recaptcha-response'])) {
   // RECAPTCHA SETTINGS
   $captcha = $_POST['g-recaptcha-response'];
   $ip = $_SERVER['REMOTE_ADDR'];
   $key = 'SECRET_KEY';
   $url = 'https://www.google.com/recaptcha/api/siteverify';

   // RECAPTCH RESPONSE
   $recaptcha_response = file_get_contents($url.'?secret='.$key.'&response='.$captcha.'&remoteip='.$ip);
   $_POST = json_decode($recaptcha_response);

   if(isset($_POST->success) &&  $_POST->success === true) {
       // code goes here
   }
   else {
      die('Your account has been logged as a spammer, you cannot continue!');
   }
}

但是我的尝试是：

//Google ReCaptcha
if(isset($_POST['g-recaptcha-response'])) {
   // RECAPTCHA SETTINGS
   $captcha = $_POST['g-recaptcha-response'];
   $ip = $_SERVER['REMOTE_ADDR'];
   $key = 'SECRET_KEY';
   $url = 'https://www.google.com/recaptcha/api/siteverify';

   // RECAPTCH RESPONSE
   $recaptcha_response = file_get_contents($url.'?secret='.$key.'&response='.$captcha.'&remoteip='.$ip);
   $_POST = json_decode($recaptcha_response);

   else {
      $errors .= 'Captcha is Required.<br/>';
   }
}

那是不正确的，但想法仍然相同，我不确定如何完成此工作。

我还有其他字段，如果尚未填写，则进行评估，如果没有填写，则脚本将通过电子邮件发送内容。如果有错误，则错误消息将记录到$ errors字符串中，然后发送到JS脚本进行打印。

那么我该如何使用Google ReCaptcha完成相同的工作？

以下是所有需要它的人的完整脚本：

<?php
require_once 'config.php';
require 'vendor/autoload.php';

    'status' => 'success',
    'message' => 'Mail sent successfully',

if (0 && strtolower($_SERVER['HTTP_X_REQUESTED_WITH']) !== 'xmlhttprequest') {
    //Invalid Ajax request
    http_response_code(403);
    $response = [
        'status' => 'error',
        'message' => 'Invalid request, please try again.',
        'data' => []
    ];
    responseHandler($response);
}

// $_POST = json_decode($_POST['data'], true); $errors = '';

//Email validation
if ( isset($_POST["userEmail"]) && !empty( $_POST["userEmail"] ) ) {
    $email = trim($_POST["userEmail"]);
    if ( filter_var($email, FILTER_VALIDATE_EMAIL) === false){
        $errors .= "$email is <strong>NOT</strong> a valid email address.<br/>";
    }

}

否则设置Google ReCaptcha并在字符串中输入错误
