董文轩的VUE实训（一）~（六）

1.安装 nodejs

2.安装 git

3.下载 vue-admin-template

删除多余界面 router/index

删除后的界面如下

import Vue from 'vue'

import Router from 'vue-router'

Vue.use(Router)

/* Layout */

import Layout from '@/layout'

/**

* Note: sub-menu only appear when route children.length >= 1

* Detail see: https://panjiachen.github.io/vue-element-admin-site/guide/essentials/router-and-nav.html

*

* hidden: true                  if set true, item will not show in the sidebar(default is false)

* alwaysShow: true              if set true, will always show the root menu

*                                if not set alwaysShow, when item has more than one children route,

*                                it will becomes nested mode, otherwise not show the root menu

* redirect: noRedirect          if set noRedirect will no redirect in the breadcrumb

* name:'router-name'            the name is used by  (must set!!!)

* meta : {

    roles: ['admin','editor']    control the page roles (you can set multiple roles)

    title: 'title'              the name show in sidebar and breadcrumb (recommend set)

    icon: 'svg-name'            the icon show in the sidebar

    breadcrumb: false            if set false, the item will hidden in breadcrumb(default is true)

    activeMenu: '/example/list'  if set path, the sidebar will highlight the path you set

  }

*/

/**

* constantRoutes

* a base page that does not have permission requirements

* all roles can be accessed

*/

export const constantRoutes = [

  {

    path: '/login',

    component: () => import('@/views/login/index'),

    hidden: true

  },

export function resetRouter() {

  const newRouter = createRouter()

  router.matcher = newRouter.matcher // reset router

}

export default router

安装ES6语法插件

npm install --save es6-promise

更改http.js

main.js中加入http

importhttpfrom'./utils/http'Vue.use(http)

index.vue

.dashboard { &-container { margin: 30px; } &-text { font-size: 30px; line-height: 46px; } }

全局安装koa-generator

cmd输入

npm install -g koa-generator

构建koa2项目的代码

koa2 projectName

成功后会出现的代码：

D:\project>koa2 projectName create:projectName create:projectName/package.json create:projectName/app.js create:projectName/publiccreate:projectName/public/images create:projectName/routes create:projectName/routes/index.js create:projectName/routes/users.js create:projectName/views create:projectName/views/index.pug create:projectName/views/layout.pug create:projectName/views/error.pug create:projectName/public/stylesheets create:projectName/public/stylesheets/style.css create:projectName/bin create:projectName/bin/www install dependencies:>cd projectName&&npm install run the app:>SETDEBUG=koa*&npm start projectName create:projectName/public/javascriptsD:\project>

初始化后台项目插件:

cd projectName

初始化项目(需要安装git)

npm install

项目试运行

npm run dev

出现以下代码代表运行成功

D:\project\projectName>npm run dev>[email protected] D:\project\projectName>nodemon bin/www[nodemon]1.19.4[nodemon]to restart at any time,enter `rs`[nodemon]watchingdir(s):*.*[nodemon]watching extensions:js,mjs,json[nodemon]starting `node bin/www`

在浏览器打开地址：

http://localhost:3000/

出现koa2的欢迎界面就代表成功了。

安装本地mongodb或者在mongodb官网新建免费的云端服务器。

百度搜索MongoDB，在官网下载。创建自己的用户。

我的数据库名字为dwx，密码用*号代替。

dbs:'mongodb+srv://dongwenxuan:******@cluster0.v7rxt.mongodb.net/dwx?retryWrites=true&w=majority'

安装Mongooes

npm install mongoose --save

下面代码中连接密码改成自己的

config.js:

module.exports={// dbs: 'mongodb://139.159.253.110:27017/test1'dbs:'mongodb+srv://xxwozixin:<需要修改>@cluster0-7d5kk.mongodb.net/test?retryWrites=true&w=majority'}

随后重启项目，运行：npm run dev

出现“mogooes 连接成功”的字样代表成功。

实训二

打开projectName文件，在models目录下创建school.js文件，接着文件操作：

constmongoose=require('mongoose')constfeld={name:String,//人物标签where:String,leixing:String}//自动添加更新时间创建时间:letpersonSchema=newmongoose.Schema(feld,{timestamps:{createdAt:'created',updatedAt:'updated'}})module.exports=mongoose.model('School',personSchema)

找到projectName下的routes目录：

constrouter=require('koa-router')()//建立模块，require(“../db/models/文件名”)letModel=require("../db/models/school");router.prefix('/school')router.get('/',function(ctx,next){ctx.body='this is a users response!'})//数据库增删改查router.post('/add',asyncfunction(ctx,next){console.log(ctx.request.body)letmodel=newModel(ctx.request.body);model=awaitmodel.save();console.log('user',model)ctx.body=model})router.post('/find',asyncfunction(ctx,next){letmodels=awaitModel.find({})ctx.body=models})router.post('/get',asyncfunction(ctx,next){// let users = await User.// find({})console.log(ctx.request.body)letmodel=awaitModel.find(ctx.request.body)console.log(model)ctx.body=model})router.post('/update',asyncfunction(ctx,next){console.log(ctx.request.body)letpbj=awaitModel.update({_id:ctx.request.body._id},ctx.request.body);ctx.body=pbj})router.post('/delete',asyncfunction(ctx,next){console.log(ctx.request.body)awaitModel.remove({_id:ctx.request.body._id});ctx.body='shibai '})module.exports=router

    path: '/school',
    component: Layout,
    meta: { title: '学校管理', icon: 'example' },
    redirect: 'school',
    children: [{
      path: 'school',
      name: 'school',
      component: () => import('@/views/school'),
      meta: { title: '学校管理', icon: 'school' }
    },
      {
        path: 'editor',

    let model = new Model(ctx.request.body);
    model = await model.save();
    console.log('user',model)
    ctx.body = model
})

router.post('/find', async function (ctx, next) {
    let models = await Model.
    find({}).populate('school')
    ctx.body = models

})
router.post('/delete', async function (ctx, next) {
    console.log(ctx.request.body)
    await Model.remove({ _id: ctx.request.body._id });
    ctx.body = 'shibai '
})
module.exports = router

在app.js中挂载路由：

const teacher= require('./routes/teacher')
app.use(teacher.routes(), teacher.allowedMethods())

前台三步骤：

打开vue-admin-template-master文件，在src/views目录下创建一个teacher模块，并在teacher目录下创建vue文件。

editor.vue为编辑文件，用于创建班级记录；

index.vue为目录文件，用于显示结果；

在index.js中添加路由：

  {
    path: '/teacher',
    component: Layout,
    meta: { title: '老师管理', icon: 'example' },
    redirect: '/teacher',
    children: [{
      path: 'teacher',
      name: 'teacher',
      component: () => import('@/views/teacher'),
      meta: { title: '老师管理', icon: 'user' }
    },
      {
        path: 'editor',
        name: 'editor',
        component: () => import('@/views/teacher/editor'),
        meta: { title: '添加老师', icon: 'user' }
      }]
  },
