  HTTP Messages

  At the core of Scamper is HttpMessage, which is a trait that defines the fundamental characteristics of an HTTP message. HttpRequest and HttpResponse extend the specification to define characteristics specific to their respective message types.

  An HttpRequest is created using a factory method defined in its companion object. Or you can start with a RequestMethod and use builder methods to further define the request.

  import scamper.Header
  import scamper.Implicits.stringToUri
  import scamper.RequestMethod.Registry.Get
  
  val request = Get("/motd").setHeaders(
    Header("Host: localhost:8080"),
    Header("Accept: text/plain")
  )
  
  printf("Request Method: %s%n", request.method)
  printf("Target URI: %s%n", request.target)
  
  request.headers.foreach(println)
  
  val host: Option[String] = request.getHeaderValue("Host")

  An HttpResponse is created using a factory method defined in its companion object. Or you can start with a ResponseStatus and use builder methods to further define the response.

  import scamper.{ BodyParser, Header }
  import scamper.Implicits.stringToEntity
  import scamper.ResponseStatus.Registry.Ok
  
  val response = Ok("There is an answer.").setHeaders(
    Header("Content-Type: text/plain"),
    Header("Connection: close")
  )
  
  printf("Status Code: %s%n", response.statusCode)
  printf("Reason Phrase: %s%n", response.reasonPhrase)
  
  response.headers.foreach(println)
  
  val contentType: Option[String] = response.getHeaderValue("Content-Type")
  
  implicit val parser = BodyParser.text()
  
  printf("Body: %s%n", response.as[String])

  Provides specialized access to message headers.

  Provides specialized access to message headers.

  Using Header Classes

  Specialized header access is provided by type classes. Some headers are available to both requests and responses, and others are available only to a specific message type. This behavior is driven by the HTTP specification.

  import scamper.Implicits.stringToUri
  import scamper.RequestMethod.Registry.Get
  import scamper.headers.{ Accept, Host }
  import scamper.types.Implicits.stringToMediaRange
  
  // Build request using 'Host' and 'Accept' headers
  val req = Get("/motd")
    .setHost("localhost:8080")
    .setAccept("text/plain")
  
  // Access and print header values
  printf("Host: %s%n", req.host)
  printf("Accept: %s%n", req.accept.mkString(", "))
