node开发后端 邮箱验证码

163邮箱为例

邮箱开通授权

后端

依赖

npm i nodemailer --save

创建发送邮件公共方法

在util问价加下新增mail.js文件

const nodemailer = require("nodemailer"); //引入依赖
/**
 * 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) {
	/**
	 * 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, // true for 465, false for other ports
		auth: {
			user: "your-email@163.com", //发送方邮箱
			pass: "123123", //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 options = {
		from: "your-email@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(options, (err, data) => {
		callback &&
			callback(err, data, () => {
				transporter.close; //成功之后，关闭连接
			});
	});
}
module.exports = mail; //导出函数

创建路由

routers文件夹中新增mailRouter.js文件

const express = require("express");
const router = express.Router();
const mail = require("../util/mail");
router.get("/getcode", (req, res) => {
	const to = "to@163.com";
	let code = Math.floor(Math.random() * 900000) + 100000; //随机生成 6位数的验证码
	if (!req.session.mailCode) {
		req.session.mailCode = {};
	}
	req.session.mailCode[to] = code;// 将指定邮箱的code记录到session中
	mail(
		to,
		"欢迎使用",
		"您的验证码为：" + code + "，请妥善保管！",
		(err, data, successCallback) => {
			if (err) {
				res.json({ code: 0, msg: err });
			} else {
				res.json({ code: 200, msg: "验证码发送成功" });
				successCallback();
			}
		}
	);
});

module.exports = router;

app.js中导入

const mailRouter = require("./routes/mailRouter");
app.use(mailRouter);

前端调用

html
<el-button type="primary" size="default" @click="sendEmailCode">
    给邮箱发送验证码
</el-button>
js
const sendEmailCode = () => {
	axios.get("/api/getcode").then((res) => {
		if (res.data.code === 200) {
			ElMessage.success(res.data.msg);
		} else {
			ElMessage.error(res.data.msg);
		}
	});
};
