Hey everyone, how can I copy an HttpRequest?

I want to send a new request in responsePipeline based on the previous request, with a small difference in the body

[Tiago Nunes]

My idea is to do something like this:

override fun install(feature: TokenAutoRefresh, scope: HttpClient) {
    scope.responsePipeline.intercept(HttpRequestPipeline.State) { (type, content) ->
        if (content !is ByteReadChannel) return@intercept

        with(feature) {
            if (context.response.isTokenValid()) {
                proceed()
            } else {
                val newToken = runCatching { refreshToken?.invoke() }.getOrNull() ?: return@intercept
                val newRequest = context.request.copy() <-- doesn't exist
scope.request(newRequest)
            }
        }
    }
}

HttpRequestBuilder().takeFrom(context.request)

is it what you need?

[Tiago Nunes]

Yes it is! Thank you very much for the fast response

[Tiago Nunes]

Do you think this will work? I can’t find any examples online…

[Rustam Siniukov]

you can check examples in Auth feature. It does very similar to what you try to achieve

I’m SO close (i think)!
I was able to make the interceptor check from the response if the token is valid, and if it isn’t, get a new token.

But now I don’t understand how to resend the request with the new token…

I tried this:

val newRequest = HttpRequestBuilder().takeFrom(context.request).apply {
    header("token", newToken)
}
proceedWith(HttpResponseContainer(type, scope.request(newRequest)))

But unfortunately, it doesn’t seem to do anything and shows no logs…
