请问在获取期刊点赞信息接口的设计时，课程里是这么设计的：GET: /:type/:id/favor, 需要传递两个参数，一个type,一个id

router.get('/:type/:id/favor', new Auth().m, async ctx => {
  const v = await new ClassicValidator().validate(ctx)
  const { type, id } = v.get('path')
  const art = await Art.getData(id, type)
  const { uid } = ctx.auth
  const likeStatus = await Favor.userLikeIt(id, type, uid)
  if (!art) {
    throw new global.errs.NotFound()
  }
  ctx.body = {
    favNums: art.favNums,
    likeStatus
  }
})

想问，如果只用期刊号(index),也能实现，从我的角度看，这种方式多调用了一次查询接口，但相对前端来说，我传递的参数都是index，对前端更友好，不是吗？ 想请问下，这样设计有什么不合理的地方吗？

下面是通过index来设计的接口：

router.get('/:index/favor', new Auth().m, async ctx => {
   const v = await new ClassicValidator().validate(ctx, {
    id: 'index'
  })
  const { index } = v.get('path')
  const flow = await Flow.findOne({
    where: {
      index
    }
  })
  if (!flow) {
    throw new global.errs.NotFound()
  }
  const { artId, type } = flow
  const art = await Art.getData(artId, type)
  const { uid } = ctx.auth
  const likeStatus = await Favor.userLikeIt(artId, type, uid)
   if (!art) {
    throw new global.errs.NotFound()
  }
  ctx.body = {
    favNums: art.favNums,
    likeStatus
  }
})
