Question

我的所有代码都设置了Google如何记录API，但它一直返回false的布尔值，我做错了吗？

<?php
  if(isset($_POST['sendEmail'])) {
    $privateKey = "__my_secret_key__";
    $response = $_POST['g-recaptcha-response'];
    $remoteip = $_SERVER['REMOTE_ADDR'];
    $url = file_get_contents("https://www.google.com/recaptcha/api/siteverify?secret=$privateKey&response=$response&remoteip=$remoteip");

    $result = json_decode($url, true);

    if($result->success == true) {
      $name = strip_tags(trim($_POST['name_1']));
      $surname = strip_tags(trim($_POST['surname_1']));
      $userArray = [
        'name' => $name,
        'surname' => $surname,
      ];
      var_dump($userArray);

    } else {
      echo "reCaptcha failed, please try again...";
    }
  }

?>

我的HTML表单包含从Google复制的JavaScript链接和我收到的data-sitekey：

<html lang="en">
<head>
  <meta charset="utf-8">
  <title>Recaptcha Example</title>
</head>

<body>
<br>
<br>
<form action="" method="post">
  <div class="form-row">
  <input name="name_1" placeholder="Your name" type="text">
  </div>

  <br>

  <div class="form-row">
  <input name="surname_1" placeholder="Your surname" type="text">
  </div>

  <br>

  <div class="form-row">
    <div class="g-recaptcha" data-sitekey="__Site_key__"></div>
  </div>

  <br>

  <input name="sendEmail" type="submit" value="Call me back">

  <br>

  <h4 id="response"></h4>
  </form>

    <script src='https://www.google.com/recaptcha/api.js'></script>
  </body>
</html>

添加此脚本：

<script src='https://www.google.com/recaptcha/api.js'></script>
<script>

function get_action(form) 
{
    var v = grecaptcha.getResponse();
    if(v.length == 0)
    {
        document.getElementById('captcha').innerHTML="You can't leave Captcha Code empty";
        return false;
    }
    else
    {
         document.getElementById('captcha').innerHTML="Captcha completed";
        return true; 
    }
}

</script>

并在提交按钮之前添加此HTML：

<div class="g-recaptcha" id="rcaptcha"  data-sitekey="site key"></div>
<span id="captcha" style="color:red" /></span> <!-- this will show captcha errors -->
