sequelize的get/post方法例子

定义两个model，一个给get的，一个给post的

var Sequelize = require('sequelize');

const DeviceNos = sequelize.define('DeviceDetail',
  {
    DeviceNo: {
      type: Sequelize.INTEGER
    }
  },
  {
    tableName: 'DeviceDetail',
    timestamps: false,
    freezeTableName: true
  })

const Device = sequelize.define('DeviceDetail',
  {
    DeviceNo: {
      type: Sequelize.INTEGER
    },
    Tem: {
      type: Sequelize.FLOAT,
      get() {
        return this.getDataValue("Tem").toFixed(2);
      }
    },
    Hum: {
      type: Sequelize.FLOAT,
      get() {
        return this.getDataValue("Hum").toFixed(2);
      }
    },
    Lng: {
      type: Sequelize.FLOAT,
      get() {
        return this.getDataValue("Lng").toFixed(2);
      }
    },
    Lat: {
      type: Sequelize.FLOAT,
      get() {
        return this.getDataValue("Lat").toFixed(2);
      }
    },

    ServiceTime: {
      type: Sequelize.DATE,
      get() {
        return moment(this.getDataValue('ServiceTime')).format('YYYY-MM-DD HH:mm:ss');
      }
    }
  }, {
    tableName: 'DeviceDetail',
    timestamps: false,
    freezeTableName: true
  });

定义运算符

const Op = Sequelize.Op;

定义get/Post方法

router.post('/searchDeviceRecord', async function (ctx, next) {
  let deviceNo = ctx.request.body.deviceNo;
  let st = ctx.request.body.st;
  let et = ctx.request.body.et;
  console.log(st);
  try {
    var data = await Device.findAll({
      attributes: ['DeviceNo', 'Tem', 'Hum', 'Lng', 'Lat', 'ServiceTime'],
      where: {
        deviceNo: deviceNo,
        serviceTime: {
          [Op.lte]: et,
          [Op.gte]: st
        }
      },
      order: [['ServiceTime', 'ASC']]
    })
    ctx.body = JSON.stringify(data);
  } catch (e) {
    console.log(e);
  }
});

router.get('/getDeviceList', async function (ctx, next) {
  try {
    var data = await DeviceNos.findAll({
      attributes: [[sequelize.literal('distinct DeviceNo'), 'DeviceNo']], order: [['DeviceNo', 'ASC']]
    })
    ctx.body = JSON.stringify(data);
  } catch (e) {
    console.log(e);
  }

});
