我有一个jquery/ajax联系人表单，并试图添加谷歌reCAPTCHA v2，但它不工作。表单工作之前，我包括验证码。reCAPTCHA显示出来了(尽管加载需要很长时间)，我可以验证我不是机器人(这也需要很长时间)，但是当我单击提交按钮时，我显示状态消息的位置显示了这个，包括代码，作为文本:
<!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>
<script src='https://www.google.com/recaptcha/api.js'></script>
并像这样整合我的表单:
<div class="g-recaptcha" data-sitekey="6LeehAsUAAAAAILDfzizJ23GHH7yPGxWBFP_3tE7"></div>
我尝试了许多不同的方法将它集成到我的mail .php文件中，但没有成功，而且我找不到许多专门针对v2的教程(不确定它是否重要)。我最新版本的mail .php是基于我在Google的recaptcha Github上发现的一个例子:
<?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"]));
$name = str_replace(array("'r","'n"),array(" "," "),$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'n";
$email_content .= "Email: $email'n'n";
$email_content .= "Message:'n$message'n";
$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.";
}
?>
这是app.js与我的联系表单(我没有改变这在试图包括reCAPTCHA时):
$(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 {
$(formMessages).text('Oops! An error occured, and your message could not be sent.');
}
});
});
});
autoload.php直接来自Google Github，我没有做任何修改:
<?php
/* An autoloader for ReCaptcha'Foo classes. This should be required()
* by the user before attempting to instantiate any of the ReCaptcha
* classes.
*/
spl_autoload_register(function ($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 $path;
}
});
好了，我修好了。它不起作用的一个原因是我必须在php.ini中启用allow_url_fopen。
然后我完全改变了代码，以摆脱autolload .php和类错误。我没有改变app.js。工作的mail .php现在看起来像这样:
<?php
// If the form was submitted
if ($_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"]));
$name = str_replace(array("'r","'n"),array(" "," "),$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'n";
$email_content .= "Email: $email'n'n";
$email_content .= "Message:'n$message'n";
$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.";
}
