mogonDB使用操作

1.电脑本地安装mogonDB 地址：https://www.mongodb.com/download-center/community进行下载安装

2.同时安装ROBO3T 地址https://robomongo.org/

3.在ssr项目nuxtjs中，安装mongoose

npm install mongoose

4.在文件夹中创建文件 

mkdir dbs

mkdir dbs/config.js

配置链接文件config.js

module.exports = {

    dbs: 'mongodb://127.0.0.1:27017/dbs'

}

创建Schema 和 models

const mongoose = require('mongoose')

let personSchema = new mongoose.Schema({name: String, age: Number})

module.exports = mongoose.model('Person', personSchema)

在app.js中需要配置

const mongoose = require('mongoose')

const dbConfig = require('./dbs/config')

mongoose.connect(dbConfig.dbs,{

useNewUrlParser:true

})

在user.js中配置增删改查，调用api

const router = require('koa-router')()

const Redis = require('koa-redis')

const Person = require('../dbs/models/person')

const Store = new Redis().client

router.prefix('/users')

router.get('/', function(ctx, next) {

ctx.body = 'this is a users response!'

})

// 增加

router.post('/addPerson', async function(ctx) {

const person = new Person({name: ctx.request.body.name, age: ctx.request.body.age})

let code

try {

await person.save()

code = 0

} catch (e) {

code = -1

}

ctx.body = {

code: code

}

})

// 查询

router.post('/getPerson', async function(ctx) {

const result = await Person.findOne({name: ctx.request.body.name})

const results = await Person.find({name: ctx.request.body.name})

ctx.body = {

code: 0,

result,

results

}

})

// 更新

router.post('/updatePerson',async function(ctx){

const result = await Person.where({

name: ctx.request.body.name

}).update({

age: ctx.request.body.age

})

ctx.body={

code:0

}

})

// 删除

router.post('/removePerson',async function(ctx){

const result = await Person.where({

name: ctx.request.body.name

}).remove()

ctx.body={

code:0

}

})

module.exports = router

最后：目录结构参考
