When using Json-feature in ktor-client to perform requests, we can do something like:

val response = client.get<MyClass>(“<https://en.wikipedia.org/wiki/Main_Page”>)

This will return convert the returned Json to MyClass. However, this won’t allow us to get additional info such as return status code etc. Is there a way to get around this?

So what you would want is a function that returns a class containing the typed instance + a instance with the response to check headers and the status of the response?

Yeah I mean we could have http response take in a class using something like:

val response = client.get<HttpResponse<Myclass>>(“<https://en.wikipedia.org/wiki/Main_Page”>)

Where MyClass defines serialized return type along with body maybe?

This is how Retrofit works, allows you to get result directly or response instance with result if you need additional information

I guess that would be a reasonable thing to add. Maybe a feature could enable this by injecting something in the pipeline so it is compatible with other transformers.

But in the meantime, you can add something like this:

data class HttpClientTypedResponse<T>(val response: HttpResponse, val instance: T) : HttpResponse by response

suspend inline fun <reified T> HttpClient.getTyped(
    url: String = "<http://127.0.0.1:8080/>",
    body: Any = EmptyContent,
    noinline block: HttpRequestBuilder.() -> Unit = {}
): HttpClientTypedResponse<T> {
    val call = call {
        url(url)
        method = HttpMethod.Get
        this.body = body
        block()
    }
    return HttpClientTypedResponse(call.response, call.receive())
}

Sure. I’ll try to add something like that soon.
