如何将多个值传递给一个参数 [英] How to pass multiple values to one parameter

问题描述

当前，我已完成代码以在参数中接受一个category_id并基于category_id返回输出.

Currently i have done code to accept one category_id in the param and return output base on category_id.

if ('category' in params) {
        assert.number(params.category, 'params.category')

        const { category: category_id } = params
        query = query.where('category.id', category_id)
      }

现在，我想将多个值传递给category_id并返回所有category_id的结果.

Now i want to pass multiple values to category_id and return result for all category_id's.

我会这样通过， category_id = 1,2,3

有人可以帮我解决这个问题吗?

Can someone helps me to fix this?
