使用Moogoose鏈接Mongodb

1.安裝：
npm install mongoose --save-dev

2.koa項目中建立models文件夾:
建立Users.js
let mongoose = require('mongoose');

let Users = mongoose.model('users', new mongoose.Schema({
email: String,
pwd: String
},{_id:true}));

module.exports = Users;

3.routers/users.js中寫:
let mongoose = require('mongoose');
let Users = require('../models/Users')

router.post('/register', async function (ctx, next) {
// let email = ctx.request.body['email'];
// let pwd = ctx.request.body['pwd'];
// ctx.body = 'email:'+email+",pwd:"+pwd;
let conn = mongoose.connect('mongodb://localhost/partner');

delete ctx.request.body['repwd'];
let users = new Users(ctx.request.body);
let rs = await users.save();
console.log(rs);
ctx.body = rs;
})
