# 1 启动mongodb数据库

 

# 2连接本地存储表

 

# 3 采用mongoose连接node

官网 https://mongoosejs.com

node项目存储数据得接口

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

# 4 再insomia中测试接口

 

# 5 在robo 3t可视化工具查看数据已经存入
