006.mongodb的模块开发

1.确保你安装了monk

npm install monk --save

2.model层如下图所示

model.js
const config = require('../config/config');

let db_url = ''
if(config.debug == false)
{
    db_url = config.db_test_url;
}
else
{
    db_url = config.db_online_url;
}
const url = db_url + '/' + config.db_table;

const db = require('monk')(url);

module.exports = db;

db.js
const db_users = require('./db/db_users');

module.exports = {
    db_users
}

db_users.js
const db = require('../model');

const users = db.get('test');

class db_user{
  async user_find(){
    let haha = await users.find({})   
    return haha;
  }  
}

var userdb = new db_user();

module.exports = userdb;

运用：

var router = require('koa-router')();
const db = require('../../model/db')

router.get('/', async (ctx)=> {
  var temp = await db.db_users.user_find();
  ctx.body = temp;
  console.log(temp)
  //db_users.user_find();
});

router.get('/cmd', function (ctx) {
  ctx.body = 'this a index/hi response!';
});

router.post('/denglu', function (ctx, next) {
  ctx.body = ctx.request.body
  console.log('123')
})

module.exports = router;
