我正在使用 PHP 和 Mailgun API 制作电子邮件订阅表格，但我只能将电子邮件发送到我在 mailgun.com 创建帐户时使用的主电子邮件地址。当我用该电子邮件填写表格时，我会收到确认信，但它不适用于其他电子邮件。为什么会这样呢？这是代码：
初始化文件：
<?php
require_once 'vendor/autoload.php';
define('MAILGUN_KEY', 'key-2ce40f5e23c90b0d666f3e....');
define('MAILGUN_PUBKEY', 'pubkey-8cf7125996....');
define('MAILGUN_DOMAIN', 'sandboxc03eaee7674c4a9094ffa8d61845ddf5.mailgun.org');
define('MAILING_LIST', '[email protected]');
define('MAILGUN_SECRET', '...');
$mailgun = new Mailgun\Mailgun(MAILGUN_KEY);
$mailgunValidate = new Mailgun\Mailgun(MAILGUN_PUBKEY);
$mailgunOptIn = $mailgun->OptInHandler();
?>
主index.php文件：
<?php
require_once 'init.php';
if(isset($_POST['name'], $_POST['email']))
{
$name = $_POST['name'];
$email = $_POST['email'];
$validate = $mailgunValidate->get('address/validate', [
'address' => $email
])->http_response_body;
if($validate->is_valid)
{
$hash = $mailgunOptIn->generateHash(MAILING_LIST, MAILGUN_SECRET, $email);
$mailgun->sendMessage(MAILGUN_DOMAIN, [
'from' => '[email protected]',
'to' => $email,
'subject' => 'Please confirm your subscription to us',
'html' => "Hello {$name}<br><br>You signed up to our mailing list. Please confirm below"
]);
$mailgun->post('lists/' . MAILING_LIST . '/members', [
'name' => $name,
'address' => $email,
'subscribed' => 'no'
]);
header('Location: http://localhost:8888/exam/index.php');
}
}
?>
