29. 使用 bcryptjs 加密

$ npm install --save bcryptjs

'use strict';
const {
  Model
} = require('sequelize');
const bcryptjs = require('bcryptjs');
module.exports = (sequelize, DataTypes) => {
  class User extends Model {
    /**
     * Helper method for defining associations.
     * This method is not a part of Sequelize lifecycle.
     * The `models/index` file will call this method automatically.
     */
    static associate(models) {
      // define association here
    }
  }
  User.init({
    email: {
      type: DataTypes.STRING,
      allowNull: false,
      validate: {
        notNull: { msg: "必须填写" },
        notEmpty: { msg: "不能为空字符串" },
        isEmail: { msg: "格式不正确" },
        async isUnique(value) {
          const user = await User.findOne({ where: { email: value } })
          if (user) {
