如何在同一return语句中返回文本语句和函数输出？

Question

我试图了解如何在if (count > 1)内返回“多个折扣”以及this.redeemDisc

`if (count > 1) {
    //return 'multiple discounts';
    return this.redeemDisc(
      {
        //BusinessId: BusinessId,
        discountId: offer.id,
        userUuid: userUuid,
        code: code,
        locationId: locationId
      }).then(redeemed => {
        return redeemed;
      }
      )
  }`

感谢您的帮助！

Answer 1

您不能返回字符串和对象，但是可以随消息一起返回对象

return { ...redeemed, message: 'multiple discounts' }

Answer 2

这将返回一个数组，其中第一个解析是您的字符串，第二个是来自请求的结果。您会同时获得两者。

    if (count > 1) {
    return Promise.all([Promise.resolve('multiple discounts'), this.redeemDisc(
        {
            //BusinessId: BusinessId,
            discountId: offer.id,
            userUuid: userUuid,
            code: code,
            locationId: locationId
        });
    )])
  }
