How to set a basePath in Ktor similar to Retrofit's `Retrofit.Builder().baseUrl(baseUrl)?

I am trying out Ktor by converting some existing project that's currently using Retrofit.

Although I could easily convert the request into something like:

client.get {
    url("$BASE_URL/something/somepage/another")
}

It seems very tedious to always add the $BASE_URL to all paths every time. In retrofit, we could simply do something like:

Retrofit.Builder()
    .baseUrl(BASE_URL)
    .create(SomeServiceClass::class.java)

I've triede using defaultRequest and setting the BASE_URL there but apparently you could only set the url.host and not the whole basePath.

Is there a way to do the same thing in Ktor? or if there is none, what's the best practice to handle this?

You can!

In order to do so you need to set your default request when you instantiate your client.

val httpClient = HttpClient(Android) {
        defaultRequest {
            host = "my.zoo.com"
            url {
                protocol = URLProtocol.HTTPS
            }
        }
    }

val response = httpClient.get<List<CatsResponse>>(
        path = "animals/cats"
)

This will call https://my.zoo.com/animals/cats

Hope it helps :)
