how can I access / manhour without writing path parameters?
in addition, I would like to ask, do not directly operate the database, only interface forwarding, koa2 can have the concept of model ?
now I am using the chained router.get ("/ manhour", controllers.manhour.get, ) to insert the data into the page, but the page cannot always have only one interface, and it is confusing to write too much, so I would like to ask if there is a model concept

routes/api.js

router.get("/api/manhour/:userid/:year/:weeks", controllers.manhour.get)

routes/manhour.js

router.get("/manhour", controllers.manhour.get, async (ctx, next) => {
    await ctx.render("manhour", {
        data: ctx.state.data,
    })
})

controllers/manhour.js

async function get(ctx, next) {
    const { userid, year, weeks } = ctx.params

    const params = {
        userid,
        year,
        weeks,
    }

    await axios.get(getWorkingTimeList, { params })
        .then(res => {
            if (res.status === 200) {
                ctx.state.code = 0
                ctx.state.data = res.data
            } else {
                ctx.state.code = -1
                ctx.state.data = {}
            }
        })

    await next()
}


module.exports = {
    get,
}
