Let's extend the JSON parser so that we get a subscription model. We will assume that the Subscription model is defined as follows:
case class Subscription(emailId: String, interval: String)
Now, let's write a parser that transforms the request body into a subscription object. The following code should be written in a controller:
val parseAsSubscription = parse.using {
request =>
parse.json.map {
body =>
val emailId:String = (body \ "emailId").as[String]
val fromDate:Long = (body \ "fromDate").as[Long]
Subscription(emailId, fromDate)
}
}
implicit val subWrites = Json.writes[Subscription]
def getSub = Action(parseAsSubscription) {
request =>
val subscription: Subscription = request.body
Ok(Json.toJson(subscription))
} There are also tolerant parsers. By tolerant, we mean that errors in a format are not ignored. This simply means that it ignores the content type header in the request...
