const User = require('../models/User');
const nodemailer = require('nodemailer');

module.exports.User = (req, res) => {   
     if(req.body.password != req.body.confirm_password){
            res.redirect('back')
        }
        
    User.findOne({email: req.body.email}, function(err, user){
        //error in creating the user
        if(err){console.log('error in creating the user');}

        //if user doesnot initially exist in the daatbase
        if(!user){
            User.create(req.body, function(err, user){
                if(err){console.log('error');}
                console.log('User created');
            })
            return res.send('<script>alert("User created")</script>');
        }
        else{
            console.log('User already present in the database');
            let mailTransporter = nodemailer.createTransport({ 
                service: 'gmail', 
                host: 'smtp.gmail.com',
                auth: { 
                    email: 'my_email',
                    pass: 'my_email_password'
                } 
            }); 
              
            let mailDetails = { 
                from: 'my_email', 
                to: req.body.email, 
                subject: 'from dhruv singhal as a project', 
                text: 'your data is successfully stored on our database'
            }; 
              
            mailTransporter.sendMail(mailDetails, function(err, data) { 
                if(err) { 
                    console.log(err); 
                } else { 
                    console.log('Email sent successfully'); 
                } 
            });

Answer 1

除了启用不太安全的应用程序之外，您是否完成了“验证码挑战”？

Answer 2

而不是email：'my_email'我相信您需要user：'my_email'。请参阅此nodemailer示例。

如另一个答案所述：在第一次从应用程序发送之前，请从相关的谷歌帐户中单击此项：https://accounts.google.com/DisplayUnlockCaptcha
