React PNPJ发送电子邮件抄送和密件抄送不工作

const nodemailer = require('nodemailer');

// 创建一个SMTP传输对象
let transporter = nodemailer.createTransport({
  host: 'smtp.example.com',
  port: 587,
  secure: false, // true for 465, false for other ports
  auth: {
    user: 'your-email@example.com',
    pass: 'your-email-password'
  }
});

// 邮件选项
let mailOptions = {
  from: 'your-email@example.com',
  to: 'recipient@example.com',
  subject: 'Test Email',
  text: 'This is a test email with CC and BCC',
  cc: 'cc-recipient@example.com', // 抄送
  bcc: 'bcc-recipient@example.com' // 密件抄送
};

// 发送邮件
transporter.sendMail(mailOptions, (error, info) => {
  if (error) {
    console.log(error);
  } else {
    console.log('Email sent: ' + info.response);
  }
});
