您可以在不使用recaptcha的情况下访问工作表单，也可以在此处访问非工作recaptcha：

首先，使用联系人表单html，您不需要css样式，也不需要教程中的斜杠

然后是send-mail.php脚本。我把我的名字叫做“send-mail\u SO2\u repact.php”

我看到您的代码中有很多错误。尝试下面的代码，看看它是否工作，它是测试和工作为我。它不是基于您所遵循的教程，而是使用curl进行验证
我认为您最大的错误是没有定义isInfected函数，=>代替->并且有时文件内容在所有服务器上都不起作用

PHP代码：
<?php
//check form is submitted
if( isset($_POST['submit']) ){

  // get values
  $error = '';
  $name          = $_POST["name"];
  $visitor_email = $_POST['web_email'];
  $message       = $_POST["message"];

  //Validate first
  if(empty($name)||empty($visitor_email)) {
    $error = "Name and email are needed!";
  }

  //handle captcha response
  $captcha = $_REQUEST['g-recaptcha-response'];
  $handle = curl_init('https://www.google.com/recaptcha/api/siteverify');
  curl_setopt($handle, CURLOPT_POST, true);
  curl_setopt($handle, CURLOPT_POSTFIELDS, "secret=YOUR_SECRET_KEY&response=$captcha");
  curl_setopt($handle, CURLOPT_RETURNTRANSFER, true);
  $response = curl_exec($handle);
  $explodedArr = explode(",",$response);
  $doubleExplodedArr = explode(":",$explodedArr[0]);
  $captchaConfirmation = end($doubleExplodedArr);
  print_r($doubleExplodedArr);
  if ( trim($captchaConfirmation) != "true" ) {
    $error = "<p>You are a bot! Go away!</p>";
  }

  if( empty($error) ){ //no error
    // mail than
    $to = "youremail@mail.com";
    $email_subject = "New Form submission";
    $email_body = "You have received a new message from ".$name.".\n".
    "sender's email:\n ".$visitor_email."\n".
    "Here is the message:\n ".$message;
    $headers = "From: ".$visitor_email." \r\n";
    $headers .= "Reply-To: ".$visitor_email." \r\n";
    //Send the email!
    $mail_check = mail($to,$email_subject,$email_body,$headers);
    if( $mail_check ){
      // echo "all is well. mail sent";
      header('Location: thank_you.html');
    } else {

这是一个对我有用的答案。我真的要感谢Galzor，因为他的回答对我帮助很大。我从代码极客那里得到的基本代码，我在这里添加了一些东西来添加到表单中。这种格式有望消除谷歌“SITE-KEY”和“SECRET-KEY”中到底应该包含什么的混淆，因为它在处理字符串之前将它们作为变量。这实际上是40个字符串。成功的验证码进入登录页

这就是所谓的send-mail_form.php。我不会在这里显示thank_you_SO2.html

Tutorial:谢谢，我按照您的示例所概述的思路编辑了HTML和PHP代码。虽然它仍然不起作用，但我觉得我离它更近了。我了解了如何将中的recaptcha表单数据与请求姓名、电子邮件和消息的原始表单数据相结合。它还显示了在哪里添加Google密钥的“秘密响应”并进行比较。然而，我现在得到一个HTTP500错误。注意，我将kaplankomputing代码中的所有引用从http更改为https。哦，作为参考，您可以在这里看到工作的普通表单和非工作的recaptcha表单：非常感谢！然而，我得到了一个新的错误。这是数组（[0]=>{“success”[1]=>false）你是一个机器人！走开！我应该说我还在学习javascript，还没有开始学习函数。在php文件中，如果我将if（trim）测试改为：if（trim（$captchaConfirmation）！=“false”）{$error=“你是一个机器人！走开！”；然后无论复选框是否选中，重述始终成功。我确实返回了谷歌，并确保我直接从谷歌复制了数据站点密钥和机密。它们以原始形式显示正确。如果您获得数组（[0]=>{“成功”[1]=>false），这意味着google没有将u作为人传递。我添加了print_r（$doubleExplodedArr）；行以显示来自recaptcha本身的原始响应。我认为代码中没有错误。可能尝试在同一页面上提交，而不是离开表单action=“”空，并在同一页上编写php代码。如果您对此感到失望，请随时发送电子邮件至aspnetusername@gmail.com.good，看起来你走的方向是对的。我再次测试了整个代码，我为你提供了另一个recaptcha密钥，它工作得很好。因此，它肯定是这个cod中的另一个这个问题阻碍了它的工作。我很高兴它成功了。干得好。希望你在过程中学到了很多。非常感谢你的帮助Galzor。你关于php电子邮件标题的文章非常有用。下面是参考：我添加的代码是$headers.=”来自：myemail@mydomain.com\r\n“；注意$headers后面的空格和句点。这是必需的，因为ISP的服务器不信任来自未知来源的邮件。
