UniApp实现用户注册与账号安全的设计与开发技巧

<template><view><input type="text" v-model="username" placeholder="手机号/邮箱"><input type="password" v-model="password" placeholder="密码"><input type="text" v-model="verificationCode" placeholder="验证码"><button>注册</button>    </view></template><script>    export default {        data() {            return {                username: '',                password: '',                verificationCode: ''            }        },        methods: {            register() {                // 前端验证用户名、密码、验证码的合法性                // 发送请求给后端接口            }        }    }</script>

const express = require('express');const app = express();app.post('/register', (req, res) => {    const { username, password, verificationCode } = req.body;        // 后端验证用户名、密码、验证码的合法性    // 数据库操作，保存用户信息，并生成唯一的用户ID        res.send({        code: 200,        message: '注册成功',        data: {            userId: 'xxxxxxxxxx'        }    });});app.listen(3000, () => {    console.log('Server is running on port 3000');});

const bcrypt = require('bcrypt');const saltRounds = 10;// 生成密码的哈希值const hashPassword = bcrypt.hashSync(password, saltRounds);// 比较用户输入的密码和数据库中保存的密码是否一致const isMatch = bcrypt.compareSync(password, hashPassword);
