the right way to POST application/x-www-form-urlencoded

[David Riccitelli]

Hello,

Is this the right way to POST x-www-form-urlencoded data using spray client (it works), or is it there a DSL to set POST params?

    val raw = "param1=%1$s&param2=%2$s&param3=%3$s".format(

      URLEncoder.encode(value1, "UTF-8"),

      URLEncoder.encode(value2, "UTF-8"),

      URLEncoder.encode(value3, "UTF-8")

    )

    

    val request = HttpRequest(method = POST, uri = "https://example.org/path",

      entity = HttpEntity(MediaTypes.`application/x-www-form-urlencoded`, raw))

    val pipeline: HttpRequest => Future[MyClass] = (

        encode(Gzip)

        ~> sendReceive

        ~> decode(Deflate)

        ~> unmarshal[MyClass]

      )

    pipeline(request) onComplete {

      case Success(myClass) => // ... add shutdown()

      case Failure(error) => // ... add shutdown()

    }

David,

you can use the `FormData` class (https://github.com/spray/spray/blob/master/spray-http/src/main/scala/spray/http/HttpForm.scala#L29), which has a predefined marshaller.
So, rather than saying:

> val raw = "param1=%1$s&param2=%2$s&param3=%3$s".format(
> URLEncoder.encode(value1, "UTF-8"),
> URLEncoder.encode(value2, "UTF-8"),
> URLEncoder.encode(value3, "UTF-8")
> )
>
> val request = HttpRequest(method = POST, uri =
> "https://example.org/path",
> entity = HttpEntity(MediaTypes.`application/x-www-form-urlencoded`,
> raw))

you can just say:

val data = Map("param1" -> value1, "param2" -> value2, "param3" -> value3)
val request = Post("https://example.org/path", FormData(data))

Cheers,
Mathias
