要想实现发送邮件功能，主要是运用nodemailer这个依赖包，官网地址：https://nodemailer.com/about/
utils.js 代码：
module.exports = {
mail
}
/**
* 发送邮件
* @param {string} to 收件方邮箱
* @param {string} title 内容标题
* @param {string} content 邮件内容
* @param {Function} callback 回调函数（内置参数）
*
*/
function mail(to,title,content,callback) {
const nodemailer = require('nodemailer'); //引入依赖
/**
* 详细配置文件地址： node_modules/lib/well-known/services
*/
let transporter = nodemailer.createTransport({
host: 'smtp.163.com',
port: 465,
secure: true,
auth: {
user: 'xxxx@163.com', //发送方邮箱
pass: 'xxx' //发送方邮箱的授权码,一般去邮箱设置里面找，应该可以找到
}
});
let info = {
from: 'xxxx@163.com',//发送方邮箱
to: to,
subject: title,
text: content
//html: '<h1>这里内容</h1>'，text和html任选其一即可
}
//发送邮件
transporter.sendMail(info,(err,data) => {
callback && callback(err,data)
})
}
NodeJs代码：
const http = require('http');
const path = require('path');
const fs = require('fs');
const url = require('url');
const utils = require(path.resolve(__dirname,'./utils.js'));
let time = null; //全局存储时间戳
let code = null; //全局存储验证码
const server = http.createServer(function (req,res) {
if (req.url == '/') {
fs.readFile('./index.html','utf8',function (err,data) {
res.writeHead(200,{'Content-type': 'text/html'});
if (err) {
res.write('文件读取错误！');
} else {
res.write(data);
}
res.end();
})
}
if (url.parse(req.url).pathname == '/date') {
let query = url.parse(req.url,true).query;
let mail = query.mail; //获取前端传递的邮箱信息
code = Math.floor(Math.random() * 1000); //存入验证码
time = new Date().getTime(); //存入发送验证码的时间戳
utils.mail(mail,'验证码',code + '',function (err,data) {
res.writeHead(200);
if (err) {
res.write('验证码发送失败')
} else {
res.write('验证码发送成功')
}
res.end();
});
}
if (url.parse(req.url).pathname == '/code') {
let query = url.parse(req.url,true).query;
let cd = query.code; //传递用户输入的验证码
let ct = query.time; //传递用户点击提交验证码的时间戳
res.writeHead(200);
console.log('code:' + code,'cd:' + cd, 'time:' + time, 'ct:' + ct)
//判断是否超过规定时间
if (ct - time >= 1 * 60 * 1000) {
res.write('验证码已过期')
} else {
if (cd == code) {
res.write('验证通过')
} else {
res.write('验证码错误')
}
}
res.end();
}
});
server.listen('80','localhost',() => {
console.log('start server!');
})
