node.js - Nodemailer 无法识别来自环境变量的凭据

问题描述

我创建了一个用于发送电子邮件的传输，如下所示：

const nodemailer = require('nodemailer');

const transport = nodemailer.createTransport({
  host: process.env.MAIL_HOST, 
  port: parseInt(process.env.MAIL_PORT),
  auth: {
    user: process.env.MAIL_USER,
    user: process.env.MAIL_PASS
  }
});

在我的variables.env文件中包含以下变量：

MAIL_USER=def
MAIL_PASS=abc
MAIL_HOST=smtp.mailtrap.io
MAIL_PORT=2525

有了这个，我得到以下错误：

(node:39148) UnhandledPromiseRejectionWarning: Error: Invalid login: 535 5.7.0 Invalid login or password

我试过控制台记录变量，它们是正确的。

console.log(process.env.MAIL_HOST)           // smtp.mailtrap.io
console.log(parseInt(process.env.MAIL_PORT)) // 2525
console.log(process.env.MAIL_USER)           // def
console.log(process.env.MAIL_PASS);          // abc

作为一种解决方法，我已经尝试过这个并且它有效：

const transport = nodemailer.createTransport({
  host: "smtp.mailtrap.io",
  port: 2525,
  auth: {
    user: "def",
    pass: "abc"
  }
});

据我所知，我看不出有什么不同。这里有什么问题？谢谢
