Nodemailer Gmail 身份验证问题

Question

我正在尝试在 Node.js 应用程序中使用 Nodemailer 通过 Gmail 发送电子邮件。但是，我遇到了身份验证问题，错误消息为“缺少‘PLAIN’的凭据”。我已经检查了我的代码和环境变量，一切似乎都是正确的。

// Import nodemailer module
import nodemailer from 'nodemailer';

// Create a transporter using Gmail SMTP
const transporter = nodemailer.createTransport({
  host: 'smtp.gmail.com',
  port: 465,
  secure: true,
  auth: {
    user: process.env.ADDRESS,
    pass: process.env.MAILING_SERVICE_APP_PASSWORD,
  },
  tls: {
    rejectUnauthorized: false, 
  },
});

// Function to send an email
async function sendEmail(to: string, subject: string, text: string) {
  // Email options
  const mailOptions = {
    from: process.env.ADDRESS,
    to: to,
    subject: subject,
    text: text,
  };

  // Send email
  return transporter.sendMail(mailOptions);
}

// Export the sendEmail function
export default sendEmail;

我已经仔细检查了我的环境变量，并且我已经为此 gmail 帐户设置了应用程序密码。但是，我仍然遇到同样的错误。有人可以帮助我确定 Nodemailer 设置的问题吗？

这就是我正在使用的，唯一的区别是我认为的端口

const nodemailer = require("nodemailer");

// async..await is not allowed in global scope, must use a wrapper
async function main() {
    // Generate test SMTP service account from ethereal.email
    // Only needed if you don't have a real mail account for testing
    let testAccount = await nodemailer.createTestAccount();

    // create reusable transporter object using the default SMTP transport
    let transporter = nodemailer.createTransport({
        host: "smtp.gmail.com",
        port: 587,
        secure: false, // true for 465, false for other ports
        auth: {
            user: '[REDACTED]',
            pass: '[Apps password redacted]',
        },
    });

    // send mail with defined transport object
    let info = await transporter.sendMail({
        from: '"Linda Lawton " <[REDACTED]>', // sender address
        to: "[REDACTED]", // list of receivers
        subject: "Hello ✔", // Subject line
        text: "Hello world?", // plain text body
        html: "<b>Hello world?</b>", // html body
    });

    console.log("Message sent: %s", info.messageId);

    // Preview only available when sending through an Ethereal account
    console.log("Preview URL: %s", nodemailer.getTestMessageUrl(info));

}

main().catch(console.error);
