如何使用PHP和Vue实现邮件发送功能

<?php
// 配置邮件服务器信息
$smtpServer = 'smtp.example.com';
$smtpPort = 465;
$smtpUsername = 'your-email@example.com';
$smtpPassWord = 'your-email-password';
?>

<?php
function sendMail($to, $subject, $content) {
    // 配置邮件服务器信息
    $smtpServer = 'smtp.example.com';
    $smtpPort = 465;
    $smtpUsername = 'your-email@example.com';
    $smtpPassword = 'your-email-password';

    // 发送邮件
    require_once('PHPMailerAutoload.php');
    $mail = new PHPMailer();
   
    $mail->iSSMTP();
    $mail->SMTPAuth = true;
    $mail->Host = $smtpServer;
    $mail->Port = $smtpPort;
    $mail->SMTPSecure = 'ssl';
    $mail->Username = $smtpUsername;
    $mail->Password = $smtpPassword;
   
    $mail->From = $smtpUsername;
    $mail->FromName = 'Your Name';
    $mail->addAddress($to);
   
    $mail->ishtml(true);
    $mail->Subject = $subject;
    $mail->Body = $content;
   
    if (!$mail->send()) {
        return false;
    } else {
        return true;
    }
}
?>

<?php
header('Access-Control-Allow-Origin: *');
header('Content-Type: application/JSON');
require 'sendMail.php';

$to = $_POST['to'];
$subject = $_POST['subject'];
$content = $_POST['content'];

if (sendMail($to, $subject, $content)) {
    echo json_encode(array('result' => 'success'));
} else {
    echo json_encode(array('result' => 'failed'));
}
?>

<script>
new Vue({
  el: '#app',
  data: {
    to: '',
    subject: '',
    content: ''
  },
  methods: {
    sendMail: function() {
      axios.post('http://localhost/sendMail.php', {
        to: this.to,
        subject: this.subject,
        content: this.content
      })
      .then(function(response) {
        console.log(response.data);
        if (response.data.result === 'success') {
          alert('邮件发送成功！');
        } else {
          alert('邮件发送失败！');
        }
      })
      .catch(function(error) {
        console.log(error);
      });
    }
  }
})
</script>
