Sequelize 日期格式化

本篇文章于 2020-12-18 初次写在我的个人小站，链接：liuxianyu.cn/article/seq…

  最近 koa2 项目中用到的 ORM 是 Sequelize V6，查询时返回的时间格式是 2020-12-18T09:11:12.668Z，希望得到的是 YYYY-MM-dd HH:mm:ss，记录一下处理过程。

一、统一配置项 推荐

  添加 dialectOptions 配置项，并设置 dateStrings、typeCast 两个参数的值为 true，如下：

const { host, user, password, database, dialect, timezone, logging } = require('../../../config/db.config')
const options = {
    host,
    dialect,
    define: {
        timestamps: false
    },
    timezone,
    logging,
    dialectOptions: {
        dateStrings: true,
        typeCast: true
    } 
}
const sequelize = new Sequelize(database, user, password, options)

二、方法转换 不推荐

const sequelize = require('sequelize')

const userInfo = await db.User.findOne({
  where,
  attributes: {
    exclude: ['isDelete', 'openId', 'password'],
    include: [
      [sequelize.Sequelize.fn('date_format', sequelize.Sequelize.col('createTime'), '%Y-%m-%d %H:%i:%s'), 'createTime'],
      [sequelize.Sequelize.fn('date_format', sequelize.Sequelize.col('updateTime'), '%Y-%m-%d %H:%i:%s'), 'updateTime'],
    ]
  }
})
