node.js發送郵件

步驟一，開啓郵箱服務

在郵箱設置裏面開啓POP3/SMTP/IMAP服務，如圖

步驟二，安裝nodemailer插件

npm install -save nodemailer

步驟三，構造以下代碼

const nodemailer=require('nodemailer');

let transporter=nodemailer.createTransport({
    host:'smtp.126.com',
    secure:true,
    auth:{
        user:'*****@126.com',
        pass:'*****'

    },
});

let mailOptions={
    from:'******@126.com',
    to:'******@163.com',
    subject:'天氣',
    text:'今每天氣很好！',
    html:'<b>今每天氣很好！</b>'
};

transporter.sendMail(mailOptions,(err,info)=>{
    if(err){
        console.log(err);
    }
    else{
        console.log(info);
    }
});

步驟四，測試

注意點

發送程序中，subject,和主題須要相一致，否則致使以下錯誤，504，SUM 信封發件人和信頭髮件人不匹配
