nodemailer
In order to send messages, those three would be following.
- Create a nodemailer transporter using either SMTP or some other transport mechanism
- Set up message options (who sends what to whom)
- Deliver the message object using the sendMail() method of your previously created transporter
nodemailer 설치하고 transporter 객체 생성하기
//install Nodemailer from npm
npm install nodemailer
//generate SMTP service account from etherea.email
const nodemailer = require("../lib/nodemailer");
nodemailer.createTestAccount((err, account) => {
if(err){
console.err('Failed to create a testing account');
console.err(err);
return process.exit(1);
}
console.log('Credentials obtained, sending message...');
//create a SMTP transporter object (to send emails you need a transporter object)
let transporter = nodemailer.createTransport(transport[, defaults]);
//defining transport와 default
let transporter = nodemailer.createTransport({
host: account.smtp.host;
port: account.smtp.port,
secure: account.smtp.port,
auth: {
user: account.user,
pass: account.pass
},
logger: true,
transactionLog: true
},
{ //default message fields
//sender info
from: 'Nodemailer <example@nodemailer.com>',
});- transporter: an object that is able to send email
- transport: the transport configuration object
- defaults: an object that defines default values for mail options
메시지 옵션 작성하고 이메일 전송하기
//Once you have a transporter object you can send mail with it
const message = {
to: 'Nodemailer <example@nodemailer.com>',
subject: 'Nodemailer is unicode friendly ✔' + Date.now(),
text: 'Hello to myself',
html: '<p><b>Hello</b> to myself</p>',
amp: `<!doctype html>
<html ⚡4email>
<head>
<meta charset="utf-8">
<style amp4email-boilerplate>body{visibility:hidden}</style>
<script async src="https://cdn.ampproject.org/v0.js"></script>
<script async custom-element="amp-anim" src="https://cdn.ampproject.org/v0/amp-anim-0.1.js"></script>
</head>
<body>
<p><b>Hello</b> to myself</p>
</body>
</html>`,
}
transporter.sendMail(data[, callback]);
transporter.sendMail(message, (error, info)=>{
if(error){
console.log('Error occurred');
console.log(error.message);
return process.exit(1);
}
console.log('Message sent successfully!');
console.log(nodemailer.getTestMessageUrl(info));
//only needed when using pooled connections
transporter.close();
});
});- data:
필수전송할 메일 내용 - callback:
옵션메시지가 전송에 성공하거나 실패했을때 동작하는 함수- err: 메시지 전송에 실패했을때 보내지는 에러 객체
- info: 사용된 전송 매커니즘에 따른 정확한 포맷의 결과를 포함한다
- info.messageId
- info.envelope
- info.accepted
- info.rejected
- info.pending
- response
- 메시지가 여러명의 수신자에게 전송되는 경우, 한 명의 수신자에게만 성공적으로 전달되어도 전송된 것으로 간주된다.
- callback 인자가 전달되지 않으면, sendMail 메소드는 프로미스 객체를 리턴시킨다. Nodemailer는 내부적으로 프로미스를 사용하지 않지만, 편의를 위해 반환을 Promise로 래핑한다.
