Koa2 Same Route Different Params

I have two endpoints:

GET all users by ID

http.get(API_URL + "users/" + id)

GET all users by username

http.get(API_URL + "users/" + username)

Can I send different parameters on a same route:

router.get("/users/:id",  async ctx => {
    //ctx.request.param is id 
    //do something

});


router.get("/users/:username",  async ctx => {
    //ctx.request.param is username 
    //do something
});

Thanks for your help!

short answer is no.

I think the good solution maybe, your route setup like this

GET /users?<your query here>

then your can query your users with <your query>.id or query>.username

In your example, you are providing URL parameters, not (named) query parameters, so it is just a part of the URL, so this is anyway "just a string".

This means, that koa router would then be aware of data types (e.g. integer for :id and string for :name). This is - as far as I know - not the case.

When you have 

"/users/:id"

or

"/users/:username"

you just give this part of the URL string a name - nothing more. (ctx.params.id OR ctx.params.username)

So you need to implement a logic, where you determine if the parameter is an integer (and handle is as an ID) or not (in which case you handle it as a username).

This could look like that:

router.get("/users/:id",  async ctx => {
    //ctx.request.id
    if (!isNaN(ctx.request.id)) // it IS a number {
        //do something with user ID
    } else {
        //do something with username
    }
});

hope that makes sense ... otherwise, you really have to create two routes with a distingiashable signature
