基于node vue的电商系统 mongodb express框架

前言
- 技术栈
- 基本功能
- - 普通用户
  - 管理员
一、运行截图？
二、使用步骤
- 1.前端main.js
- 2.后端admin路由
- 源码

前言

技术栈

本项目采用前后端分离的开发方式，使用的技术栈是:Vue+Node+MongoDB
前端：用vue-cli搭建，使用vue全家桶+element-ui
后端：express框架
数据库：mongodb

基本功能

普通用户

注册、登录
根据关键词对商品模糊搜索
根据分类查询商品
商品详情展示
加入购物车及创建订单
商品评论
用户个人中心（修改个人信息及查看订单）

管理员

登录
用户管理
权限管理
商品管理
订单管理
数据统计

提示：以下是本篇文章正文内容，下面案例可供参考

一、运行截图？

二、使用步骤

1.前端main.js

代码如下（示例）：

import Vue from 'vue'
import App from './App'
import router from './router'
import store from './store&#fig.productionTip = false//图片懒加载
import LazyLoad from 'vue-lazyload'
Vue.use(LazyLoad, {error:require('./assets/img/error.png'),// 占位图loading:require('./assets/img/loading.png')
})//引入ElementUI库
import ElementUI from 'element-ui'
import 'element-ui/lib/theme-chalk/index.css'
Vue.use(ElementUI);//省市区联动
import VueAreaLinkage from 'vue-area-linkage';
import 'vue-area-linkage/dist/index.css';
Vue.use(VueAreaLinkage);//引入图标库
import 'assets/fonts/iconfont.css'//引入全局样式
import 'assets/css/base.css'//事件总线
Vue.prototype.$bus = new Vue();new Vue({router,store,render: h => h(App)
}).$mount('#app')//通过methods里的代码跳转路由需要写下面代码: (不然重复点击会报错)
import Router from 'vue-router'
const routerPush = place
place = function replace(location) {return routerPush.call(this, location).catch(error => error)
}

2.后端admin路由

代码如下（示例）：

import express from 'express'
import mongoose from 'mongoose'
import path from 'path'
import md5 from 'blueimp-md5'
import formidable from 'formidable'
import config from '../src/config.js'
import {Administrator,User,Category,Goods,Comment,Order
} from '../db/db'
const router = express.Router();const S_KEY = 'leavehao@foxmail' //盐//管理员登录
router.post('/login', async (req, res) => {let adminName = req.body.adminName;let adminPsw = md5(md5(req.body.adminPsw) + S_KEY);let result = await Administrator.findOne({adminName})if (result) {if (adminPsw === result.password) {req.session.admin = adminName;res.json({status_code: 200,message: '登录成功',})} else {res.json({status_code: 400,message: '密码错误'})}} else {res.json({status_code: 400,message: '用户名不存在'})}
})//设置后台访问权限
router.use((req, res, next) => {if (!req.session.admin) {res.json({status_code: 400,message: '无权访问'})}next();
})// 验证登录状态,若未被中间件拦截则为登录状态
('/isadmin', async (req, res) => {console.log(req.session.admin)if(req.session.admin){let result = await Administrator.findOne({adminName: req.session.admin})console.log(result)res.json({status_code: 200,message: '进入管理员界面',adminName: req.session.admin,role: le})}})//退出登录
