Endpoint requires authentication Rest API Spray - scala

Question

I would like to consume some resources from This Rest API
But it seems that I need some Authorization. And actually as a beginner I don't know how to access to this endpoint using Spray.
A simple example of Spray Client:
val pipeline = sendReceive ~> unmarshal[GuildwarsApiResult]
val responseFuture = pipeline {
Get("https://api.guildwars2.com/v2/commerce/listings/46741")
}
Thanks !

I see a lot of questions lately from people who want to use API of GuilWars. Was it recently created ?
As per your question you need to specify HTTP header with API token as stated in documentation for POST requests. For GET requests you should pass token in URL.
This shows how to create and use custom http header.
object ApiTokenHeader extends ModeledCustomHeaderCompanion[ApiTokenHeader] {
def renderInRequests = false
def renderInResponses = false
override val name = "Authorization"
override def parse(value: String) = Try(new ApiTokenHeader(value))
}
final class ApiTokenHeader(token: String) extends ModeledCustomHeader[ApiTokenHeader] {
def renderInRequests = false
def renderInResponses = false
override val companion = ApiTokenHeader
override def value: String = "Bearer " + token
}
and use it as
val responseFuture = pipeline {
Get("https://api.guildwars2.com/v2/commerce/listings/46741").withHeaders(ApiTokenHeader("55eec993e046c63bc8f486ee"))
}
I didn't compile it but it should work.
