用malgun api php发送邮件

Question

大家。

如何通过mailgun API服务正确发送邮件？

尝试这种方式：

$name = strip_tags(htmlspecialchars($_POST['name']));
$phone = strip_tags(htmlspecialchars($_POST['phone']));

// mailgun
function send_mailgun($email){
    $config = array();
    $config['api_key'] = "key-32312312-12312312312-8";
    $config['api_url'] = "https://api.mailgun.net/v3/domain.com/messages";
    $message = array();
    $message['from'] = "test@gmail.com";
    $message['to'] = $email;
    $message['subject'] = "Eye-Catching Subject Line";
    $ch = curl_init();

    curl_setopt($ch, CURLOPT_URL, $config['api_url']);
    curl_setopt($ch, CURLOPT_HTTPAUTH, CURLAUTH_BASIC);
    curl_setopt($ch, CURLOPT_USERPWD, "api:{$config['api_key']}");
    curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
    curl_setopt($ch, CURLOPT_CONNECTTIMEOUT, 10);
    curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, 0);
    curl_setopt($ch, CURLOPT_SSL_VERIFYHOST, 0);
    curl_setopt($ch, CURLOPT_POST, true); 
    curl_setopt($ch, CURLOPT_POSTFIELDS,$message);
    $result = curl_exec($ch);
    curl_close($ch);
    return $result;
}


send_mailgun('test@gmail.com');

但是，它不起作用。根本不发送电子邮件。使用Mailgun和php发送简单表单提交值的最简单/最快方法是什么？
