Nodejs使用mongoose

框架：nodejs+express+mongoose+es6

import mongoose from 'mongoose'
import config from '../config'
var DB_URL = config.mongodb_url;
mongoose.Promise = global.Promise;
/**
 * 连接
 */
mongoose.connect(DB_URL);

/**
  * 连接成功
  */
mongoose.connection.on('connected', function () {
    console.log('Mongoose connection success to ' + DB_URL);
});

/**
 * 连接异常
 */
mongoose.connection.on('error',function (err) {
    console.log('Mongoose connection error: ' + err);
});

/**
 * 连接断开
 */
mongoose.connection.on('disconnected', function () {
    console.log('Mongoose connection disconnected');
});

export default mongoose

创建Model

import mongoose from '../db/mongooseDb'


var Schema = mongoose.Schema;

var UsersSchema = new Schema({
    uid : { type: String },
    type: {type: Number}, /
    uname: {type: String},
    logintime : { type: Date, default: Date.now}                      
    }, { versionKey: false });//去掉版本控制

const Users = mongoose.model('User',UsersSchema);

export default Users

使用

async getUserInfo(){
   var userInfo = await  UsersModel.findOne({ 'uid': result.UId })
}
