How to create a method which prints the entire Request and Response in Play? - playframework-2.6

Question

I want to create a helper method which could be called from a Controller and prints the different parameters of the Request. I tried to do something like following but I need to pass type parameter to Request. What should I pass for type parameter?
import play.api.mvc.Request
package object utilities {
def printPlayHttpRequest (request:Request): Unit ={ //Request needs type parameter. What should I pass as type parameter?
}
}
Looking at the apply method of Request object, it seems that the type parameter passed corresponds to the Body type. So do I need to pass some body type?
def apply[A](rh: RequestHeader, body: A): Request[A]

Answer 1

From Play documentation, I suppose the A in Request[A] corresponds to type of body and it could be any Scala type as the request body, for example String, NodeSeq, Array[Byte], JsonValue, or java.io.File, as long as we have a body parser able to process it
From documentation
Previously we said that an Action was a Request => Result function. This is not entirely true. Let’s have a more precise look at the Action trait:
trait Action[A] extends (Request[A] => Result) {
def parser: BodyParser[A]
}
First we see that there is a generic type A, and then that an action must define a BodyParser[A]. With Request[A] being defined as:
trait Request[+A] extends RequestHeader {
def body: A
}
The A type is the type of the request body. We can use any Scala type as the request body, for example String, NodeSeq, Array[Byte], JsonValue, or java.io.File, as long as we have a body parser able to process it.
To summarize, an Action[A] uses a BodyParser[A] to retrieve a value of type A from the HTTP request, and to build a Request[A] object that is passed to the action code.
Following is my implementation
import play.api.mvc.{AnyContent, Request}
package object utilities {
def printPlayHttpRequest (request:Request[AnyContent]): Unit ={
println(s"Attr: ${request.attrs}, \n Body: ${request.body}, \n connection: ${request.connection}, \n headers: ${request.headers}, \n method: ${request.method}, \n target: ${request.target}, \n version: ${request.version}, \n mediatype: ${request.mediaType}")
}
}
