nodemailer不在服务器上发送电子邮件？

Question

所以我创建了一个带有 react 前端和 node js 和 nodemailer 后端的表单。我正在尝试通过电子邮件发送该数据。我可以将它发送到后端，接收效果很好但是，我在发送电子邮件时遇到问题，因为从 Transporter.sendMail 函数执行“邮件未发送”错误，我不确定为什么。

很想得到一些帮助。请查看我的服务器的以下代码。出于安全考虑，我显然删除了我的身份验证详细信息。

控制台日志错误：

[0] 未发送

const nodemailer = require('nodemailer');
const path = require('path');
const express = require("express");
const app = express();
const port = 5000;
const cors = require("cors");
app.use(cors());
const bodyParser = require("body-parser");
app.use(bodyParser.json()); // to support JSON-encoded bodies
app.use(
  bodyParser.urlencoded({
    // to support URL-encoded bodies
    extended: true
  })
);

const transporter = nodemailer.createTransport({
  service: 'gmail',
  auth: {
    user: 'email',
    pass: 'password',

  }
});




app.get("/home", (req, res) => {
    console.log("Hello from .get /home", req.body.generalDetails, req.body.firstName, req.body.mName );

})






app.post("/home", (req, res) => {

  var mailOptions = {
                from: 'email',
                to: 'email',
                subject: 'Hello',
                text: req.body.generalDetails,

            }

            transporter.sendMail(mailOptions, function(err, res) {
                if (err) {
                    console.log('Mail not sent');
                } else {
                    console.log('Mail sent');
                }
            });

  let data = [{
    //page one data
    generalDetails: req.body.generalDetails,
    fName: req.body.fName,
    mName: req.body.mName,
    lName: req.body.lName,
    email: req.body.email,

   }];

   res.json(data);
 }

);



app.listen(port, () => `Server running on port ${port}`);

我想在你的代码中修改一些sn-ps如下：

const smtpTransport = nodemailer.createTransport({
  service: "Gmail", // <======
  auth: {
    user: YOUR_GMAIL_ADDRESS,
    pass: YOUR_GMAIL_PASSWORD
  }
});
...
let mailOptions = {
  from: FROM_ADDRESS,
  to: TARGET_MAIL_ADDRESS,
  subject: 'Hello',
  text: req.body.generalDetails,
  html: req.body.generalDetails, // <======
};
smtpTransport.sendMail(mailOptions, function (err) {
  if (err) {
    // failed
  } else {
    // sent
  }
});
...

PS：如果仍然出现错误日志，为什么不分享？
