main.js中加入http

import http from './utils/http'
Vue.use(http)

index.vue ↓

<template>
  <div class="dashboard-container">
    歡迎
  </div>
</template>

<script>
  import { mapGetters } from 'vuex'

  export default {
    name: 'Dashboard',
    computed: {
      ...mapGetters([
        'name'
      ])
    },
    mounted(){
      this.$http.get('/api/users/add').then(res => {
        console.log('this.panels', res)
      })
    }
  }
</script>

<style lang="scss" scoped>
  .dashboard {
    &-container {
      margin: 30px;
    }
    &-text {
      font-size: 30px;
      line-height: 46px;
    }
  }
</style>

6.全局安裝koa-generator,執(zhí)行下面命令

npm install -g koa-generator

7.構(gòu)建koa2項(xiàng)目代碼如下

koa2 projectName

構(gòu)建成功信息：

D:\project>koa2 projectName

   create : projectName
   create : projectName/package.json
   create : projectName/app.js
   create : projectName/public
   create : 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:
     > SET DEBUG=koa* & npm start projectName

   create : projectName/public/javascripts

D:\project>

初始化后臺項(xiàng)目插件，命令屬下:

cd projectName

初始化項(xiàng)目锹杈，如果沒有安裝git會報(bào)錯(cuò)

npm install

項(xiàng)目試運(yùn)行

npm run dev

這里koa2模板提示信息做的并不好，沒有輸出測試地址鳖链，成功后出現(xiàn)如下界面代表成功了葛超。

D:\project\projectName>npm run dev

> projectName@0.1.0 dev D:\project\projectName
> nodemon bin/www

[nodemon] 1.19.4
[nodemon] to restart at any time, enter `rs`
[nodemon] watching dir(s): *.*
[nodemon] watching extensions: js,mjs,json
[nodemon] starting `node bin/www`

在瀏覽器打開地址：
http://localhost:3000/
出現(xiàn)koa2的歡迎界面就代表成功了瓢姻。

8.安裝本地mongodb或者在mongodb官網(wǎng)新建免費(fèi)的云端服務(wù)器祝蝠。

本人在這里用的mongodb免費(fèi)云端數(shù)據(jù)庫。
抱歉密碼不能公開幻碱，請自行換成自己的密碼
鏈接如下：

mongodb+srv://xxwozixin:<password>@cluster0-7d5kk.mongodb.net/test?retryWrites=true&w=majority

安裝mongoose

npm install mongoose --save

在第7步建好的nodejs項(xiàng)目中根目錄創(chuàng)建db目錄
作者用的webstorm,可以根據(jù)自己需要下載編輯器
下面代碼中連接密碼需要修改成自己的
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'
}

user.js ↓

const mongoose = require('mongoose')
const feld={
    name: String,
    age: Number,
    //人物標(biāo)簽
    labels:Number
}
//自動添加更新時(shí)間創(chuàng)建時(shí)間:
let personSchema = new mongoose.Schema(feld, {timestamps: {createdAt: 'created', updatedAt: 'updated'}})
module.exports= mongoose.model('User',personSchema)

修改根目錄app.js
app.js ↓

const Koa = require('koa')
const app = new Koa()
const views = require('koa-views')
const json = require('koa-json')
const onerror = require('koa-onerror')
const bodyparser = require('koa-bodyparser')
const logger = require('koa-logger')

const index = require('./routes/index')
const users = require('./routes/users')


const mongoose = require('mongoose')
const dbconfig = require('./db/config')
mongoose.connect(dbconfig.dbs, {useNewUrlParser: true,useUnifiedTopology: true})
const db = mongoose.connection
db.on('error', console.error.bind(console, 'connection error:'));
db.once('open', function() {
  console.log('mongoose 連接成功')
});
// error handler
onerror(app)

// middlewares
app.use(bodyparser({
  enableTypes:['json', 'form', 'text']
}))
app.use(json())
app.use(logger())
app.use(require('koa-static')(__dirname + '/public'))

app.use(views(__dirname + '/views', {
  extension: 'pug'
}))

// logger
app.use(async (ctx, next) => {
  const start = new Date()
  await next()
  const ms = new Date() - start
  console.log(`${ctx.method} ${ctx.url} - ${ms}ms`)
})

// routes
app.use(index.routes(), index.allowedMethods())
app.use(users.routes(), users.allowedMethods())

// error-handling
app.on('error', (err, ctx) => {
  console.error('server error', err, ctx)
});

module.exports = app

// error handler
onerror(app)

// middlewares
app.use(bodyparser({
  enableTypes:['json', 'form', 'text']
}))
app.use(json())
app.use(logger())
app.use(require('koa-static')(__dirname + '/public'))

app.use(views(__dirname + '/views', {
  extension: 'pug'
}))

// logger
app.use(async (ctx, next) => {
  const start = new Date()
  await next()
  const ms = new Date() - start
  console.log(`${ctx.method} ${ctx.url} - ${ms}ms`)
})

// routes
app.use(index.routes(), index.allowedMethods())
app.use(users.routes(), users.allowedMethods())

// error-handling
app.on('error', (err, ctx) => {
  console.error('server error', err, ctx)
});

module.exports = app

user.js ↓

const router = require('koa-router')()
const User = require('../db/models/user')
router.prefix('/users')

router.get('/add', function (ctx, next) {
    ctx.body = 'this is a users/bar response'
})

router.get('/', function (ctx, next) {
  ctx.body = 'this is a users response!'
})

router.get('/bar', function (ctx, next) {
  ctx.body = 'this is a users/bar response'
})

module.exports = router

重啟項(xiàng)目
關(guān)掉前面我們啟動的服務(wù)在運(yùn)行

npm run dev

如下結(jié)果代表成功連接數(shù)據(jù)庫

屏幕截圖 2020-12-14 113538.png

到這里前后端就連接通了续膳，可以開始操作數(shù)據(jù)庫。
一收班、后臺三步驟：
1、打開projectName文件谒兄，在models目錄下創(chuàng)建school.js文件摔桦，接著文件操作：

const mongoose = require('mongoose')
const feld={
    name: String,
    //人物標(biāo)簽
    where:String,
    leixing: String
}
//自動添加更新時(shí)間創(chuàng)建時(shí)間:
let personSchema = new mongoose.Schema(feld, {timestamps: {createdAt: 'created', updatedAt: 'updated'}})
module.exports= mongoose.model('School',personSchema)

2、找到projectName下的routes目錄：

const router = require('koa-router')()
//建立模塊，require(“../db/models/文件名”)
let Model = require("../db/models/school");
router.prefix('/school')

router.get('/', function (ctx, next) {
    ctx.body = 'this is a users response!'
})

//數(shù)據(jù)庫增刪改查
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({})
    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
})

router.post('/update', async function (ctx, next) {
    console.log(ctx.request.body)
    let pbj = await Model.update({ _id: ctx.request.body._id }, ctx.request.body);
    ctx.body = pbj
})
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

3.在app.js中掛載路由：

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

二邻耕、前臺三步驟：
打開vue-admin-template-master文件鸥咖，在src/views目錄下創(chuàng)建一個(gè)school模塊：

屏幕截圖 2020-12-18 124345.png

并在school目錄下創(chuàng)建vue文件。

1.editor.vue為編輯文件兄世，用于創(chuàng)建學(xué)校記錄啼辣；

<template>
  <div class="dashboard-container">
    <el-form ref="form" :model="form" label-width="80px">
      <el-form-item label="學(xué)校名稱">
        <el-input v-model="form.name"></el-input>
      </el-form-item>
      <el-form-item label="位置">
        <el-input v-model="form.where"></el-input>
      </el-form-item>
      <el-form-item label="類型">
        <el-input v-model="form.leixing"></el-input>
      </el-form-item>
      <el-form-item>
        <el-button type="primary" @click="onSubmit">立即創(chuàng)建</el-button>
        <el-button>取消</el-button>
      </el-form-item>

    </el-form>
  </div>
</template>

        form:{}
      }
    },
    methods:{
      onSubmit(){
        console.log('222:', 222)
        if(this.form._id){
          this.$http.post(`/api/${this.apiModel}/update`,this.form).then(res => {
            console.log('bar:', res)
            this.$router.push({path:this.apiModel})
            this.form={}

2.index.vue為目錄文件，用于顯示結(jié)果御滩；

<template>

  import { mapGetters } from 'vuex'

  export default {

      ])
    },
    data() {
      return {

3.在index.js中添加路由：

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

一鸥拧、后臺三步驟：
1、打開projectName文件削解，在models目錄下創(chuàng)建academy.js文件富弦，接著文件操作：

const mongoose = require('mongoose')
const Schema= mongoose.Schema
const feld={
    name: String,
    //人物標(biāo)簽
    major:String,
    renshu: Number,
    school : { type: Schema.Types.ObjectId, ref: 'School' }
}
//自動添加更新時(shí)間創(chuàng)建時(shí)間:
let schema = new Schema(feld, {timestamps: {createdAt: 'created', updatedAt: 'updated'}})
module.exports= mongoose.model('Academy',schema)

2、找到projectName下的routes目錄氛驮，創(chuàng)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
})

router.post('/update', async function (ctx, next) {
    console.log(ctx.request.body)
    let pbj = await Model.update({ _id: ctx.request.body._id }, ctx.request.body);
    ctx.body = pbj
})
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

3.在app.js中掛載路由：

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

二腕柜、前臺三步驟：
打開vue-admin-template-master文件，在src/views目錄下創(chuàng)建一個(gè)academy模塊：

    },
    methods: {
      onSubmit() {

3.在index.js中添加路由：

{
    path: '/classs',
    component: Layout,
    meta: { title: '班級管理', icon: 'example' },
    redirect: '/classs',
    children: [{
      path: 'classs',
      name: 'classs',
      component: () => import('@/views/classs'),
      meta: { title: '班級管理', icon: 'classs' }
    },
      {
        path: 'editor',
        name: 'editor',
        component: () => import('@/views/classs/editor'),
        meta: { title: '添加班級', icon: 'classs' }
      }]
  },

1豺谈、打開projectName文件郑象，在models目錄下創(chuàng)建student.js文件，接著文件操作：

const mongoose = require('mongoose')
const Schema = mongoose.Schema
const feld={
    name: String,
    age: Number,
    student_number:Number,
    gender:String,
    school : { type: Schema.Types.ObjectId, ref: 'School' },
    academy : { type: Schema.Types.ObjectId, ref: 'Academy' },
    classs : { type: Schema.Types.ObjectId, ref: 'Classs' }

}
//自動添加更新時(shí)間創(chuàng)建時(shí)間:
let personSchema = new mongoose.Schema(feld, {timestamps: {createdAt: 'created', updatedAt: 'updated'}})
module.exports= mongoose.model('Student',personSchema)

2茬末、找到projectName下的routes目錄厂榛，創(chuàng)建student.js文件：

const router = require('koa-router')()
let Model = require("../db/models/student");
router.prefix('/student')

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('classs').populate('academy').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
})

router.post('/update', async function (ctx, next) {
    console.log(ctx.request.body)
    let pbj = await Model.update({ _id: ctx.request.body._id }, ctx.request.body);
    ctx.body = pbj
})
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

3.在app.js中掛載路由：

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

3.在index.js中添加路由：

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