课程目标

• 运用vue+vue-router+vuex+element-ui搭建网站
• 对项目进行需求分析和模块划分以及功能划分
• 实现首页+全部+品牌周边页面渲染
• 查看商品详情页制作、商品排序以及分页功能实现
• 使用token+jwt实现网站用户登录退出 (后台)
• 使用meta元信息实现路由权限控制
• 实现加入购物车、图片懒加载功能
• 实现数据持久化存储用户数据和购物车数据
• 项目优化以及如何打包上线整个流程

项目初始化

• vue create xmall_front

• 项目目录如下

  

• 

cd xmall_front
npm run server
//访问https://localhost:8080

效果如下：

安装依赖

• 安装sass:npm install -D sass-loader node-sass 现在是：npm install -D sass-loader sass 地址：https://cli.vuejs.org/zh/guide/css.html#预处理器

• 安装element-ui第三方组件库：vue add element

• 安装图片懒加载插件：npm i vue-lazyload -S 安装vant解决后期懒加载警告图片显示不了问题：npm i vant@2.12.47 -S

• 安装请求库：npm i axios -S

• 注意版本问题：

  

jwt-token原理:

• 安装 模拟后端数据一些对应模块

npm i jsonwebtoken -S

npm i cors -S

npm i body-parse -S

npm i express -S

路由配置

import Vue from 'vue'
import VueRouter from 'vue-router'


// import Index from "../views/Index";
// import Login from '../views/Login'
// import Home from '../views/Home'
// import Goods from '../views/Goods'
// import Thanks from '../views/Thanks'

// 解决路由命名冲突的方法
const routerPush = VueRouter.prototype.push
VueRouter.prototype.push = function push(location) {
  return routerPush.call(this, location).catch(error => error)
}

// 异步组件加载，控制台中通过查看source查看到js分成很多小文件加载（而不是一个大的app.js加载），减轻资源消耗问题
const Index = ()=> import('@/views/Index')
const Login = ()=> import('@/views/Login')
const Home = ()=> import('@/views/Home')
const Goods = ()=> import('@/views/Goods')
const Thanks = ()=> import('@/views/Thanks')


Vue.use(VueRouter)

const routes = [
  {
    path: '/',
    name: 'Home',
    redirect: '/home',
    component: Index,
    children:[
      {
        path: '/home',
        name: 'Home',
        component: Home,
      },
      {
        path: '/goods',
        name: 'Goods',
        component: Goods,
      },
      {
        path: 'goodsDetail',
        name: 'GoodsDetail',
        component: ()=>import('@/views/GoodsDetail')
      },
      {
        path: 'thanks',
        name: 'Thanks',
        component: Thanks,
      },
      {
        path: 'user',
        name: 'User',
        component: ()=>import('@/views/User'),
        meta:{
          auth:true
        }
      },

    ]
  },
  {
    path: '/login',
    name: 'Login',
    component: Login,
  }

]

const router = new VueRouter({
  mode: 'history',    // 去除路由的#
  base: process.env.BASE_URL,
  routes
})

export default router

修改db文件夹的位置到当前server目录下

测试启动: nodemon app.js

浏览器访问：http://localhost:3000/api/goods/home拿到全部数据

修改项目中端口地址：http://localhost:3000/

阿里云买台服务器

登录服务器

用户名：ssh root@123.206.16.61

安装node二进制文件

node版本必须高于8，否则后面 npm install 会报错

cd /tmp/

wget https://nodejs.org/download/release/v10.15.3/node-v10.15.3-linux-x64.tar.xz

解压node

xz -d node-v10.15.3-linux-x64.tar.xz :去除掉.xz后缀

tar -xf node-v10.15.3-linux-x64.tar

配置环境变量

ln -s /opt/node-v10.15.3-linux-x64/bin/node  /usr/local/sbin/ 
ln -s /opt/node-v10.15.3-linux-x64/bin/npm  /usr/local/sbin/

安装pm2进程管理工具

npm install pm2 -g

部署Node后端

• git pull https://www.github.com/xiaomage/server
• 模拟本地文件上传到服务器
  • 本地终端运行：scp ./server.zip root@123.206.16.61:/tmp
  • 服务器终端运行：unzip server.zip && cd server && npm install && pm2 start app.js

开放3000端口在防火墙中：

部署Vue前端项目

前端打包文件dist：

npm run build

• 本地终端运行：scp ./dist.zip root@123.206.16.61:/tmp

• 服务器终端运行：unzip dist.zip

部署nginx

找到nginx的安装目录

//以我的服务器为例：nginx目录
cd /opt/ngx112/conf 
vim nginx.conf

//修改配置文件如下
 server {
        listen       80; //端口号
        server_name  www.pythonav.cn; //域名
        location / {
                 try_files $uri $uri/ /index.html;  #匹配所有的路由
                 root /tmp/dist; //填写前端的根目录
            index  index.html index.htm;
        }
    }

输入nginx的启动命令

nginx 第一次输入是启动
nginx -s reload  #平滑重启，重新读取配置文件，不重启进程
nginx -s stop
