ajax,jquery联系表单与reCAPTCHA v2 - 500内部服务器错误

I have a jquery/ajax contact form and tried to add the Google reCAPTCHA v2, but it isn't working. The form worked before I included the reCAPTCHA. The reCAPTCHA shows up (although it takes forever to load), and I can verify that I'm not a robot (which takes forever as well), but when I click on my submit button, the spot where I display my status messages shows this, including the code, as text:

<!DOCTYPE HTML PUBLIC "-//IETF//DTD HTML 2.0//EN"> <html><head> <title>500 Internal Server Error</title> </head><body> <h1>Internal Server Error</h1> <p>The server encountered an internal error or misconfiguration and was unable to complete your request.</p> <p>Please contact the server administrator, and inform them of the time the error occurred, and anything you might have done that may have caused the error.</p> <p>More information about this error may be available in the server error log.</p> </body></html> 

I can't figure out what's going wrong. I followed Google's instructions and included this just before my tag:

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

and integrated my form like this:

<div class="g-recaptcha" data-sitekey="6LeehAsUAAAAAILDfzizJ23GHH7yPGxWBFP_3tE7"></div>

I tried many different ways to integrate it in my mailer.php file without success, and I couldn't find many tutorials that address v2 specifically (not sure if it even matters). My most recent version of the mailer.php is based on an example I found on Google's recaptcha Github:

<?php
require_once __DIR__ . 'inc/autoload.php';
// If the form was submitted    
if ($_SERVER["REQUEST_METHOD"] == "POST") {

  // If the Google Recaptcha box was clicked
  if(isset($_POST['g-recaptcha-response']) && !empty($_POST['g-recaptcha-response'])){
        $siteKey = '6LeehAsUAAAAAILDfzizJ23GHH7yPGxWBFP_3tE7';
        $secret = 'I-removed-this-for-now';
        $recaptcha = new \ReCaptcha\ReCaptcha($secret);            
        $resp = $recaptcha->verify($gRecaptchaResponse, $remoteIp);

        // If the Google Recaptcha check was successful
        if ($resp->isSuccess()){
            $name = strip_tags(trim($_POST["name"]));
            $name = str_replace(array("","
"),array(" "," "),$name);
            $email = filter_var(trim($_POST["email"]), FILTER_SANITIZE_EMAIL);
            $message = trim($_POST["message"]);
            if ( empty($name) OR empty($message) OR !filter_var($email, FILTER_VALIDATE_EMAIL)) {
                http_response_code(400);
                echo "Oops! There was a problem with your submission. Please complete the form and try again.";
                exit;
            }
            $recipient = "I-removed-this@for-now.com";
            $subject = "New message from $name";
            $email_content = "Name: $name
";
            $email_content .= "Email: $email

";
            $email_content .= "Message:
$message
";
            $email_headers = "From: $name <$email>";
            if (mail($recipient, $subject, $email_content, $email_headers)) {
                http_response_code(200);
                echo "Thank You! Your message has been sent.";
            } 

            else {
                http_response_code(500);
                echo "Oops! Something went wrong, and we couldn't send your message. Check your email address.";
            }

        } 

        // If the Google Recaptcha check was not successful    
        else {
            echo "Robot verification failed. Please try again.";
        }

    } 

    // If the Google Recaptcha box was not clicked   
    else {
        echo "Please click the reCAPTCHA box.";
    }      

} 

// If the form was not submitted
// Not a POST request, set a 403 (forbidden) response code.         
else {
    http_response_code(403);
    echo "There was a problem with your submission, please try again.";
}      
?>

This is the app.js that goes with my contact form (I haven't changed this at all when trying to include the reCAPTCHA):

$(function() {

    // Get the form.
    var form = $('#ajax-contact');

    // Get the messages div.
    var formMessages = $('#form-messages');

    // Set up an event listener for the contact form.
    $(form).submit(function(e) {
        // Stop the browser from submitting the form.
        e.preventDefault();

        // Serialize the form data.
        var formData = $(form).serialize();

        // Submit the form using AJAX.
        $.ajax({
            type: 'POST',
            url: $(form).attr('action'),
            data: formData
        })
        .done(function(response) {
            // Make sure that the formMessages div has the 'success' class.
            $(formMessages).removeClass('error');
            $(formMessages).addClass('success');

            // Set the message text.
            $(formMessages).text(response);

            // Clear the form.
            $('#name').val('');
            $('#email').val('');
            $('#message').val('');
        })
        .fail(function(data) {
            // Make sure that the formMessages div has the 'error' class.
            $(formMessages).removeClass('success');
            $(formMessages).addClass('error');

            // Set the message text.
            if (data.responseText !== '') {
                $(formMessages).text(data.responseText);
            } else {
                $(formMessages).text('Oops! An error occured, and your message could not be sent.');
            }
        });

    });

});

The autoload.php comes directly from the Google Github, and I didn't make any changes:

<?php

/* An autoloader for ReCaptcha\Foo classes. This should be required()
 * by the user before attempting to instantiate any of the ReCaptcha
 * classes.
 */

spl_autoload_register(function ($class) {
    if (substr($class, 0, 10) !== 'ReCaptcha\\') {
      /* If the class does not lie under the "ReCaptcha" namespace,
       * then we can exit immediately.
       */
      return;
    }

    /* All of the classes have names like "ReCaptcha\Foo", so we need
     * to replace the backslashes with frontslashes if we want the
     * name to map directly to a location in the filesystem.
     */
    $class = str_replace('\\', '/', $class);

    /* First, check under the current directory. It is important that
     * we look here first, so that we don't waste time searching for
     * test classes in the common case.
     */
    $path = dirname(__FILE__).'/'.$class.'.php';
    if (is_readable($path)) {
        require_once $path;
    }

    /* If we didn't find what we're looking for already, maybe it's
     * a test class?
     */
    $path = dirname(__FILE__).'/../tests/'.$class.'.php';
    if (is_readable($path)) {
        require_once $path;
    }
});

I would really appreciate your help!

    Okay, I fixed it. One reason it wasn't working was that I had to enable allow_url_fopen in php.ini.

    Then I completely changed the code to get rid of that autoload.php and the class error. I didn't change app.js. The working mailer.php now looks like this:

    <?php
    // If the form was submitted
    if ($_SERVER["REQUEST_METHOD"] == "POST") {
    
        // If the Google Recaptcha box was clicked
        if(isset($_POST['g-recaptcha-response']) && !empty($_POST['g-recaptcha-response'])){
            $captcha=$_POST['g-recaptcha-response'];
            $response=file_get_contents("https://www.google.com/recaptcha/api/siteverify?secret=MYKEY&response=".$captcha."&remoteip=".$_SERVER['REMOTE_ADDR']);
            $obj = json_decode($response);
    
            // If the Google Recaptcha check was successful
            if($obj->success == true) {
              $name = strip_tags(trim($_POST["name"]));
              $name = str_replace(array("","
    "),array(" "," "),$name);
              $email = filter_var(trim($_POST["email"]), FILTER_SANITIZE_EMAIL);
              $message = trim($_POST["message"]);
              if ( empty($name) OR empty($message) OR !filter_var($email, FILTER_VALIDATE_EMAIL)) {
                http_response_code(400);
                echo "Oops! There was a problem with your submission. Please complete the form and try again.";
                exit;
              }
              $recipient = "I-removed-this@for-now.com";
              $subject = "New message from $name";
              $email_content = "Name: $name
    ";
              $email_content .= "Email: $email
    
    ";
              $email_content .= "Message:
    $message
    ";
              $email_headers = "From: $name <$email>";
              if (mail($recipient, $subject, $email_content, $email_headers)) {
                http_response_code(200);
                echo "Thank You! Your message has been sent.";
              } 
    
              else {
                http_response_code(500);
                echo "Oops! Something went wrong, and we couldn't send your message. Check your email address.";
              }
    
          } 
    
          // If the Google Recaptcha check was not successful    
          else {
            echo "Robot verification failed. Please try again.";
          }
    
      } 
    
      // If the Google Recaptcha box was not clicked   
      else {
        echo "Please click the reCAPTCHA box.";
      }      
    
    } 
    
    // If the form was not submitted
    // Not a POST request, set a 403 (forbidden) response code.         
    else {
      http_response_code(403);
      echo "There was a problem with your submission, please try again.";
    }      
    ?>
