备忘--node连接mongodb

const express = require(‘express‘);
const router = express.Router()

const mongoose = require(‘mongoose‘)
mongoose.connect(‘mongodb://localhost:27017/testdb‘, { useNewUrlParser: true })

const PositionModel = mongoose.model(‘positions‘, {
  positionName: String,
})
const position = new PositionModel({
  positionName: ‘就安大略‘
})
router.post(‘/save‘, (req, res) => {
  position.save().then((result) => {
    console.log(result)
    res.send(‘datas have saved mongodb‘)
  });
})

module.exports = router
