我正试图建立一个非常基本的网站，包括reCAPTCHA。我已经获得了我的站点密钥和秘密密钥，并且到目前为止，我已经完成了两个教程的学习，但运气不佳

  <form method="post" action="verify.php">
    Number:<br> 
    <input type="text" name="number"><br>
    <?php
      require_once('recaptchalib.php');
      $publickey = "your_public_key"; // you got this from the signup page
      echo recaptcha_get_html($publickey);
    ?>
    <input type="submit" />
  </form>

sites的目标是使用表单从用户处获取一个数字作为输入，并在reCAPTCHA成功并按下submit按钮后显示一个字符串

  <form method="post" action="verify.php">
    Number:<br> 
    <input type="text" name="number"><br>
    <?php
      require_once('recaptchalib.php');
      $publickey = "your_public_key"; // you got this from the signup page
      echo recaptcha_get_html($publickey);
    ?>
    <input type="submit" />
  </form>

这是我的php

<html>
<body>

The number is <?php echo $_GET["number"]; ?><br>

<?php 
  if ($_GET["number"] == 42)
  echo "42 is the right answer!";
?>

</body>
</html>

  <form method="post" action="verify.php">

到目前为止，该网站工作良好。。。除了我不知道如何添加reCAPTCHA代码和Google文档之外，我很困惑，因为我对php知之甚少

  <form method="post" action="verify.php">
    Number:<br> 
    <input type="text" name="number"><br>
    <?php
      require_once('recaptchalib.php');
      $publickey = "your_public_key"; // you got this from the signup page
      echo recaptcha_get_html($publickey);
    ?>
    <input type="submit" />
  </form>

非常感谢您提供任何代码示例或简单文档的链接。这是我关于stackoverflow的第一篇文章。。。我希望我能很好地遵守规则

这将是您的verify.php

$post_data = http_build_query(
    array(
        'secret' => CAPTCHA_SECRET, //as provided from google
        'response' => $_POST['g-recaptcha-response'],
        'remoteip' => $_SERVER['REMOTE_ADDR']
    )
);
$opts = array('http' =>
    array(
        'method'  => 'POST',
        'header'  => 'Content-type: application/x-www-form-urlencoded',
        'content' => $post_data
    )
);
$context  = stream_context_create($opts);
$response = file_get_contents('https://www.google.com/recaptcha/api/siteverify', false, $context);
$result = json_decode($response);
if ($result->success) {
//success,
echo $_GET["firstname"]; //your input field name was 'firstname' not 'number'

}else{
echo 'we think you are a bot';
//fail

}

  <form method="post" action="verify.php">
    Number:<br> 
    <input type="text" name="number"><br>
    <?php
      require_once('recaptchalib.php');
      $publickey = "your_public_key"; // you got this from the signup page
      echo recaptcha_get_html($publickey);
    ?>
    <input type="submit" />
  </form>

我建议将您的HTML代码更改为：

  <form method="post" action="verify.php">
    Number:<br> 
    <input type="text" name="number"><br>
    <?php
      require_once('recaptchalib.php');
      $publickey = "your_public_key"; // you got this from the signup page
      echo recaptcha_get_html($publickey);
    ?>
    <input type="submit" />
  </form>

  <!-- more of your HTML content -->
</body>

  <form method="post" action="verify.php">
    Number:<br> 
    <input type="text" name="number"><br>
    <?php
      require_once('recaptchalib.php');
      $publickey = "your_public_key"; // you got this from the signup page
      echo recaptcha_get_html($publickey);
    ?>
    <input type="submit" />
  </form>

  <form method="post" action="verify.php">
    Number:<br> 
    <input type="text" name="number"><br>
    <?php
      require_once('recaptchalib.php');
      $publickey = "your_public_key"; // you got this from the signup page
      echo recaptcha_get_html($publickey);
    ?>
    <input type="submit" />
  </form>

  <!-- more of your HTML content -->

并在verify.php中添加以下内容：

<form method="post" action="verify.php"> Number:<br> <input type="text" name="number"><br> <?php require_once('recaptchalib.php'); $publickey = "your_public_key"; // you got this from the signup page echo recaptcha_get_html($publickey); ?> <input type="submit" /> </form>  </body>

<?php require_once('recaptchalib.php'); $privatekey = "your_private_key"; $resp = recaptcha_check_answer ($privatekey, $_SERVER["REMOTE_ADDR"], $_POST["recaptcha_challenge_field"], $_POST["recaptcha_response_field"]); if (!$resp->is_valid) { // What happens when the CAPTCHA was entered incorrectly die ("The reCAPTCHA wasn't entered correctly. Go back and try it again." . "(reCAPTCHA said: " . $resp->error . ")"); } else { // Your code here to handle a successful verification if (isset($_POST['number']) && $_POST['number'] == '42') { echo "42 is the right answer!"; } } ?>

OP需要recaptchalib.php 我使用的教程。。。向我介绍了“recaptchalib.php”文件。。。但是当我运行代码时。。。我收到错误。。。主要的一个似乎连接到第124行，这一行的部分说[错误代码]，我想用这个文件来帮助我更好地理解reCAPTCHA和php。。。但是对于像我这样的外行来说，关于这些东西的教程似乎大部分都没有。谢谢你的回复，我修正了你注意到的打字错误，并添加了我的密钥，但是。。。现在，当我运行应用程序时，我得到了以下错误：“注意：未定义的索引：C:\Users\Brandon\Google Drive\WWWWWW\Middle\verify.php中的g-recaptcha-response，在第10行”我的问题可能是我使用的是localhost吗？我有localhost和127.0.0.1作为我的域用于RecaptchayYour表单需要使用POST，不，我很感激我爱你们，哈哈，太谢谢你们了！几年来，我一直想建立一个这样的reCAPTCHA东西
