0. 사전준비 사항

메일 발송하는 계정은 테스트 계정으로 새로 만들어서 테스트 하시는것을 추천합니다.

1) 보안 수준이 낮은 앱 엑세스 허용

보안 수준이 낮은 앱 허용을 해줘야 테스트 하는 어플리케이션에서 메일 발송이 가능합니다.

아래 URL을 클릭하시면 로그인 되어있는 계정으로 바로 설정 가능합니다.

https://myaccount.google.com/lesssecureapps

2) 내 Google 계정에 대한 액세스 허용

내 Google 계정에 대한 액세스 허용화면에서 계속 버튼을 클릭 해줍니다.

아래 URL을 클릭하시면 로그인 되어있는 계정으로 바로 설정 가능합니다.

1. nodemailer 모듈

nodemailer는 node 서버에서 메일을 보낼 수 있는 메일 전송 모듈입니다. 사용법이 간편하다는 장점이 있습니다.

nodemailer 공식문서는 하단 URL을 참고해주세요

https://nodemailer.com/about/

npm을 사용하시는 분들은 npm install nodemailer --save yarn을 사용하시는 분들은
yarn add nodemailer 명령으로 설치 가능합니다.

2. nodemailer을 이용한 발송 코드

1) nodemailer 발송 모듈

// nodemailer 모듈 요청
var nodemailer = require('nodemailer');

// 메일발송 객체
var mailSender = {
    // 메일발송 함수
    sendGmail : function(param){
        var transporter = nodemailer.createTransport({
            service: 'gmail'
            ,prot : 587
            ,host :'smtp.gmlail.com'
            ,secure : false
            ,requireTLS : true
            , auth: {
              user: '발송할 메일@gmail.com'
              ,pass: '패스워드'
            }
        });
        // 메일 옵션
        var mailOptions = {
                from: '발송할 메일@gmail.com',
                to: param.toEmail, // 수신할 이메일
                subject: param.subject, // 메일 제목
                text: param.text // 메일 내용
            };
        // 메일 발송    
        transporter.sendMail(mailOptions, function(error, info){
            if (error) {
            console.log(error);
            } else {
            console.log('Email sent: ' + info.response);
            }
        });

    }
}
// 메일객체 exports
module.exports = mailSender;

2) 메일 발송 함수 사용

let emailParam = {
    toEmail : loginId
    ,subject  : '메일 제목'
    ,text : '메일 내용'
};
mail.sendGmail(emailParam);
