node.js模拟实现自动发送邮件验证码

npm i -S nodemailer

//1. 导入nodemailer
const nodemailer = require('nodemailer')
//2. 创建运输对象
let transporter = nodemailer.createTransport({
    host: 'smtp.qq.com',
    secure: true,
    auth: {
        user: '5641132547@qq.com',//输入你开启SMTP服务的QQ邮箱
        pass: 'oxpbfzjtnurbjhei' //输入我们刚才获得的那串字符
    }
})
//3.配置发送邮件的信息
let mailOptions = {
    from: '5641132547@qq.com', // 发送者,也就是你的QQ邮箱
    to: '12938203121@qq.com', // 接受者邮箱,可以同时发送多个,以逗号隔开
    subject: '测试发送邮件', // 邮件标题
    html: `
<p>这是我的测试邮件</p>
<p>哈哈哈，收到请回复</p>	
    `      //邮件内容，以html的形式输入，在邮件中会自动解析显示
};
//4.发送邮件
transporter.sendMail(mailOptions, function(err, data){
	//回调函数，用于判断邮件是否发送成功
	...
})

const nodemailer = require('nodemailer')
let transporter = nodemailer.createTransport({
    host: 'smtp.qq.com',
    secure: true,
    auth: {
        user: '5641132547@qq.com',
        pass: 'asdasfsfwqqw' 
    }
});
module.exports = async function fn(email, code){
    let status = null
    await new Promise((resolve, reject) => {
        transporter.sendMail({
            from: '5641132547@qq.com',
            to: email, 
            subject: '网站账户注册验证码',
            html: `
            <p>网站账户注册验证码：</p>
        <span style="font-size: 18px; color: red">` + code + `</span>`
        }, function (err, info) {
            if (err) {
                status = 0
                reject()
            } else {
                status = 1
                resolve()
            }
        });
    })
    return status
}

//导入我们sendEmail.js文件中导出的东西
const sendEmail = require('./sendEmail.js')
//此时sendEmail是一个函数，可传参数有 email, code , 执行完会返回一个status, 用于判断是否发送成功
const result = sendEmail('190380192@qq.com', 568712)
if(result === 0) {
	console.log('邮件发送失败')
}
else if(result === 1) {
	console.log('邮件发送成功')
}
