js邮箱验证怎么做

function validateEmail(email) {
    const re = /^(([^<>()\[\]\\.,;:\s@"]+(\.[^<>()\[\]\\.,;:\s@"]+)*)|(".+"))@((\[[0-9]{1,3}\.[0-9]{1,3}\.[0-9]{1,3}\.[0-9]{1,3}\])|(([a-zA-Z\-0-9]+\.)+[a-zA-Z]{2,}))$/;
    return re.test(String(email).toLowerCase());
}

// 使用示例
const email = "example@example.com";
if (validateEmail(email)) {
    console.log("邮箱格式正确");
} else {
    console.log("邮箱格式不正确");
}

const express = require('express');
const nodemailer = require('nodemailer');
const app = express();
app.use(express.json());

// 假设我们有一个数据库模型User
const User = require('./models/User');

// 发送验证邮件的函数
async function sendVerificationEmail(email, token) {
    let transporter = nodemailer.createTransport({
        service: 'gmail',
        auth: {
            user: 'your-email@gmail.com',
            pass: 'your-email-password'
        }
    });

    let mailOptions = {
        from: 'your-email@gmail.com',
        to: email,
        subject: '邮箱验证',
        text: `点击以下链接验证你的邮箱: http://yourdomain.com/verify/${token}`
    };

    await transporter.sendMail(mailOptions);
}

// 注册路由
app.post('/register', async (req, res) => {
    const { email } = req.body;
    const token = generateUniqueToken(); // 生成唯一令牌的函数

    // 保存用户和令牌到数据库
    const user = new User({ email, verificationToken: token });
    await user.save();

    // 发送验证邮件
    await sendVerificationEmail(email, token);

    res.send('注册成功，请检查你的邮箱进行验证');
});

// 验证路由
app.get('/verify/:token', async (req, res) => {
    const { token } = req.params;

    // 查找用户并验证令牌
    const user = await User.findOne({ verificationToken: token });
    if (user) {
        user.verified = true;
        user.verificationToken = undefined; // 清除令牌
        await user.save();
        res.send('邮箱验证成功');
    } else {
        res.send('无效的验证令牌');
    }
});

app.listen(3000, () => console.log('Server started on port 3000'));
