1.安装 nodejs
2.安装 git
3.下载 vue-admin-template
删除多余界面 router/index

前台三步骤
打开vue-admin-template-master文件，在src/views目录下创建一个school模块
并在school目录下创建vue文件。
editor.vue为编辑文件，用于创建学校记录

实训三
后台三步骤：
打开projectName文件，在models目录下创建academy.js文件，接着文件操作：
const mongoose = require('mongoose')
const Schema= mongoose.Schema
const feld={

major:String,
renshu: Number,

}
//自动添加更新时间创建时间:
let schema = new Schema(feld, {timestamps: {createdAt: 'created', updatedAt: 'updated'}})
module.exports= mongoose.model('Academy',schema)
找到projectName下的routes目录，创建academy.js文件：
const router = require('koa-router')()
let Model = require("../db/models/academy");
router.prefix('/academy')
router.get('/', function (ctx, next) {
ctx.body = 'this is a users response!'
})
router.post('/add', async function (ctx, next) {
console.log(ctx.request.body)
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('/get', async function (ctx, next) {
// let users = await User.
// find({})
console.log(ctx.request.body)
let model = await Model.find(ctx.request.body)
console.log(model)
ctx.body = model

console.log(ctx.request.body)
await Model.remove({ _id: ctx.request.body._id });
ctx.body = 'shibai '
})
module.exports = router

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