How to parse Json data returned from a HTTP request in scala

I am trying to parse JSON data returned from an HTTP request as below. import scalaj.http.{Http, HttpResponse}

import scala.util.parsing.json.JSON
import scalaj.http.{Http, HttpResponse}

object ScalaHttp {
    def main(args: Array[String]): Unit = {
        def get(url: String,i: Int) = Http(url).param("page",i.toString)
        for(i <- 1 to 15 by 1) {
            var jsonFile = get("url",i).asString
            println(jsonFile)
        }
    }
}

The data comes in pages so I looped through all the pages manually from 1 to 15 and each page returns one element give below. When I print the string:L jsonFile, I see the string in below format:

HttpResponse({"run_sessions":[{"id":9003843,"start_time":"2012-02-22T10:59:06.000Z","end_time":"2012-02-22T11:52:43.000Z","duration":3217769,"distance":13644,"encoded_trace":null,"sport_type_id":3},{"id":9000024,"start_time":"2012-02-22T09:12:51.000Z","end_time":"2012-02-22T18:49:26.000Z","duration":7009,"distance":0,"encoded_trace":null,"sport_type_id":7},{"id":9003605,"start_time":"2012-02-21T12:21:00.000Z","end_time":"2012-02-21T12:43:47.000Z","duration":1367000,"distance":2600,"encoded_trace":"kd}wHuo~n@?fDlCbG?vE{@|GfB|FmAjHzCtIzBmEhAgGcE}DuDyEuE}DaCeEAsHjDSrBnDlBaA_EuGf@aEGjD","sport_type_id":1},{"id":9003604,"start_time":"2012-02-21T12:21:00.000Z","end_time":"2012-02-21T12:44:02.000Z","duration":1382000,"distance":2600,"encoded_trace":"gd}wHiq~n@_@hDvDpGe@nEi@tG~C|FgDtFxCjKvCaB`CqFsEuEgDcFkEsCaCyH{@}D|CmBrBhCxCp@oE}Hb@wEDn@","sport_type_id":1},{"id":9003952,"start_time":"2012-02-21T12:15:00.000Z","end_time":"2012-02-21T12:59:59.000Z","duration":2699120,"distance":6990,"encoded_trace":"ktcsGi~x]{@]rD~@{Jt@k@jI{BfJqJ{a@f@xa@}CmGsHa\\\\KhJsD}CaA}MrO{`@cCrL|Iub@hCsJvAyClB}DxAqD`EtA}End@rCtFdKiQbCdAbDaH~B}FjAlDbGlCvMmCyLf\\\\?nEnAhL{B|H}@hEvWiPqBbEan@|\\\\h@oDqBrCuDgILaHhBeFzGgFxE|@pB|BdBnCl@rC{Bt@qB~BJnG}@tA","sport_type_id":1},{"id":9004251,"start_time":"2012-02-21T12:07:13.000Z","end_time":"2012-02-21T14:38:45.000Z","duration":7820873,"distance":54670,"encoded_trace":"ybtzHqgx_@ifAp}Bw^n}B{Dl{DhBlqDqzCvi@aWdaDtf@~tCru@x~CdL~mExYjuEhoBqNvlC{gAbtA`mAxByyCx@{eFm`@wuF_j@elGiMqeG_k@a{E_y@w`D","sport_type_id":4},{"id":9004249,"start_time":"2012-02-21T12:07:04.000Z","end_time":"2012-02-21T13:41:35.000Z","duration":5676621,"distance":8909,"encoded_trace":"irveHulcvAMP{CzWiGvEyEtCs@uHiDzIqBfH{ErH{ExD{HuBgFvA{Dr@o@jH}D`GqFpE}GeBvAmExBqFjOcBRzDkEvFeH`GgGy@n@iIdEmHtO`@uGxLcL|EaC_GjDkFxMaF`DxDiErGkGhFsFVk@qHxCqF`QaGnHgCfEjAdGB|FoDlDgFbCgIpBcGrBJrArFxAkIhGuCzDa@?yU","sport_type_id":2},{"id":9004252,"start_time":"2012-02-21T12:07:00.000Z","end_time":null,"duration":0,"distance":0,"encoded_trace":null,"sport_type_id":1},{"id":9004245,"start_time":"2012-02-21T12:06:51.000Z","end_time":"2012-02-21T12:39:51.000Z","duration":1760262,"distance":4579,"encoded_trace":"axfvBrsr|Q?GTeCp@_EdBkD|@uD\\\\sDVuA}@`DWpDs@nDiAzCaAvDIn@r@oDhAmDdAsDd@cDb@}CJ_Aq@~Da@`Di@lDyArCq@dDSlBj@iDr@{CzA_Et@cEDaC`AqCeAxC?zBu@pCq@rCsAxCk@rCOfAl@aDbAwDrA_Dp@iDV}CRiAq@|De@rDk@zCkAnC_AhDSdC","sport_type_id":1},{"id":9004243,"start_time":"2012-02-21T12:06:48.000Z","end_time":"2012-02-21T13:05:57.000Z","duration":3547966,"distance":8096,"encoded_trace":"ckrtGs_ew@cZ_R_]gXg\\\\hAaJu@iBwJ_N{OuHuGiE{XKgNlCcLkAhLNbN`Kt_@dQxSnFnMzL}UfOxL`f@da@|VdV??","sport_type_id":1},{"id":9004239,"start_time":"2012-02-21T12:06:48.000Z","end_time":"2012-02-21T14:53:22.000Z","duration":9985106,"distance":13048,"encoded_trace":null,"sport_type_id":2},{"id":9004238,"start_time":"2012-02-21T12:06:47.000Z","end_time":"2012-02-21T12:21:38.000Z","duration":891191,"distance":2721,"encoded_trace":"u{ckGiy`LBHPjBHrBpAxAPnBIdC]xCU`CVpBF~BLnBpArA|ApAjAj@lAn@hBj@~A_@lBKbAmBb@eB?aCEgA}Aw@w@NiA]iAOuAF{Bp@kA`BX|B^~BxAvAxAp@jBi@`@iDb@wCmAs@}AYQaAL{Bd@uBVyCL{CY}AyAAuAKiBs@}AgA}@uAoAcB]g@","sport_type_id":1},{"id":9004232,"start_time":"2012-02-21T12:06:34.000Z","end_time":"2012-02-21T12:08:16.000Z","duration":101937,"distance":845,"encoded_trace":null,"sport_type_id":9},{"id":9004230,"start_time":"2012-02-21T12:06:30.000Z","end_time":null,"duration":0,"distance":0,"encoded_trace":null,"sport_type_id":1},{"id":9004226,"start_time":"2012-02-21T12:06:18.000Z","end_time":null,"duration":0,"distance":0,"encoded_trace":null,"sport_type_id":5}],"meta":{"pagination":{"per_page":15,"available_pages":71,"total":1059,"page":"1","sort_by":"start_time","order":"desc"}}},200,Map(Cache-Control -> Vector(max-age=0, private, must-revalidate), Connection -> Vector(keep-alive), Content-Length -> Vector(3727), Content-Type -> Vector(application/json; charset=utf-8), Date -> Vector(Tue, 01 Oct 2019 11:44:24 GMT), Etag -> Vector("2269df166d2348a8adc43b8170651bc8"), Server -> Vector(WEBrick/1.3.1 (Ruby/1.9.3/2014-05-14)), Set-Cookie -> Vector(request_method=GET; path=/), Status -> Vector(HTTP/1.1 200 OK), Via -> Vector(1.1 vegur), X-Content-Type-Options -> Vector(nosniff), X-Frame-Options -> Vector(SAMEORIGIN), X-Request-Id -> Vector(321da733-1172-4547-90a2-42d5d3b027fa), X-Runtime -> Vector(0.068370), X-Ua-Compatible -> Vector(chrome=1), X-Xss-Protection -> Vector(1; mode=block)))

Libraries used:

name := "ScalaRest"

version := "0.1"

scalaVersion := "2.11.8"
libraryDependencies += "org.scalaj" %% "scalaj-http" % "2.3.0"

It has Maps, Sets in the string which I don't understand how to parse. From the above string which is in JSON format, how can I parse the data and extract data of the elements: id, starttime, endtime, duration

Most safe and efficient way to parse the body of that HTTP response is using of jsoniter-scala.

1) Add dependencies:

libraryDependencies ++= Seq(
  "com.github.plokhotnyuk.jsoniter-scala" %% "jsoniter-scala-core"   % "0.55.4" % Compile,
  "com.github.plokhotnyuk.jsoniter-scala" %% "jsoniter-scala-macros" % "0.55.4" % Provided // required only in compile-time
)

2) Define data structures, derive codec for the root structure and parse the response body:

import java.time.Instant

import com.github.plokhotnyuk.jsoniter_scala.macros._
import com.github.plokhotnyuk.jsoniter_scala.core._

case class Response(
  run_sessions: List[RunSession],
  meta: Meta)

case class RunSession(
  id: Int,
  start_time: Instant,
  end_time: Option[Instant],
  duration: Int,
  distance: Int,
  encoded_trace: Option[String],
  sport_type_id: Int)

case class Meta(pagination: Pagination)

case class Pagination(
  per_page: Int,
  available_pages: Int,
  total: Int,
  @stringified page: Int,
  sort_by: String,
  order: String)

implicit val codec: JsonValueCodec[Response] = JsonCodecMaker.make(CodecMakerConfig())

val body: Array[Byte] = """{"run_sessions":[{"id":9003843,"start_time":"2012-02-22T10:59:06.000Z","end_time":"2012-02-22T11:52:43.000Z","duration":3217769,"distance":13644,"encoded_trace":null,"sport_type_id":3},{"id":9000024,"start_time":"2012-02-22T09:12:51.000Z","end_time":"2012-02-22T18:49:26.000Z","duration":7009,"distance":0,"encoded_trace":null,"sport_type_id":7},{"id":9003605,"start_time":"2012-02-21T12:21:00.000Z","end_time":"2012-02-21T12:43:47.000Z","duration":1367000,"distance":2600,"encoded_trace":"kd}wHuo~n@?fDlCbG?vE{@|GfB|FmAjHzCtIzBmEhAgGcE}DuDyEuE}DaCeEAsHjDSrBnDlBaA_EuGf@aEGjD","sport_type_id":1},{"id":9003604,"start_time":"2012-02-21T12:21:00.000Z","end_time":"2012-02-21T12:44:02.000Z","duration":1382000,"distance":2600,"encoded_trace":"gd}wHiq~n@_@hDvDpGe@nEi@tG~C|FgDtFxCjKvCaB`CqFsEuEgDcFkEsCaCyH{@}D|CmBrBhCxCp@oE}Hb@wEDn@","sport_type_id":1},{"id":9003952,"start_time":"2012-02-21T12:15:00.000Z","end_time":"2012-02-21T12:59:59.000Z","duration":2699120,"distance":6990,"encoded_trace":"ktcsGi~x]{@]rD~@{Jt@k@jI{BfJqJ{a@f@xa@}CmGsHa\\\\KhJsD}CaA}MrO{`@cCrL|Iub@hCsJvAyClB}DxAqD`EtA}End@rCtFdKiQbCdAbDaH~B}FjAlDbGlCvMmCyLf\\\\?nEnAhL{B|H}@hEvWiPqBbEan@|\\\\h@oDqBrCuDgILaHhBeFzGgFxE|@pB|BdBnCl@rC{Bt@qB~BJnG}@tA","sport_type_id":1},{"id":9004251,"start_time":"2012-02-21T12:07:13.000Z","end_time":"2012-02-21T14:38:45.000Z","duration":7820873,"distance":54670,"encoded_trace":"ybtzHqgx_@ifAp}Bw^n}B{Dl{DhBlqDqzCvi@aWdaDtf@~tCru@x~CdL~mExYjuEhoBqNvlC{gAbtA`mAxByyCx@{eFm`@wuF_j@elGiMqeG_k@a{E_y@w`D","sport_type_id":4},{"id":9004249,"start_time":"2012-02-21T12:07:04.000Z","end_time":"2012-02-21T13:41:35.000Z","duration":5676621,"distance":8909,"encoded_trace":"irveHulcvAMP{CzWiGvEyEtCs@uHiDzIqBfH{ErH{ExD{HuBgFvA{Dr@o@jH}D`GqFpE}GeBvAmExBqFjOcBRzDkEvFeH`GgGy@n@iIdEmHtO`@uGxLcL|EaC_GjDkFxMaF`DxDiErGkGhFsFVk@qHxCqF`QaGnHgCfEjAdGB|FoDlDgFbCgIpBcGrBJrArFxAkIhGuCzDa@?yU","sport_type_id":2},{"id":9004252,"start_time":"2012-02-21T12:07:00.000Z","end_time":null,"duration":0,"distance":0,"encoded_trace":null,"sport_type_id":1},{"id":9004245,"start_time":"2012-02-21T12:06:51.000Z","end_time":"2012-02-21T12:39:51.000Z","duration":1760262,"distance":4579,"encoded_trace":"axfvBrsr|Q?GTeCp@_EdBkD|@uD\\\\sDVuA}@`DWpDs@nDiAzCaAvDIn@r@oDhAmDdAsDd@cDb@}CJ_Aq@~Da@`Di@lDyArCq@dDSlBj@iDr@{CzA_Et@cEDaC`AqCeAxC?zBu@pCq@rCsAxCk@rCOfAl@aDbAwDrA_Dp@iDV}CRiAq@|De@rDk@zCkAnC_AhDSdC","sport_type_id":1},{"id":9004243,"start_time":"2012-02-21T12:06:48.000Z","end_time":"2012-02-21T13:05:57.000Z","duration":3547966,"distance":8096,"encoded_trace":"ckrtGs_ew@cZ_R_]gXg\\\\hAaJu@iBwJ_N{OuHuGiE{XKgNlCcLkAhLNbN`Kt_@dQxSnFnMzL}UfOxL`f@da@|VdV??","sport_type_id":1},{"id":9004239,"start_time":"2012-02-21T12:06:48.000Z","end_time":"2012-02-21T14:53:22.000Z","duration":9985106,"distance":13048,"encoded_trace":null,"sport_type_id":2},{"id":9004238,"start_time":"2012-02-21T12:06:47.000Z","end_time":"2012-02-21T12:21:38.000Z","duration":891191,"distance":2721,"encoded_trace":"u{ckGiy`LBHPjBHrBpAxAPnBIdC]xCU`CVpBF~BLnBpArA|ApAjAj@lAn@hBj@~A_@lBKbAmBb@eB?aCEgA}Aw@w@NiA]iAOuAF{Bp@kA`BX|B^~BxAvAxAp@jBi@`@iDb@wCmAs@}AYQaAL{Bd@uBVyCL{CY}AyAAuAKiBs@}AgA}@uAoAcB]g@","sport_type_id":1},{"id":9004232,"start_time":"2012-02-21T12:06:34.000Z","end_time":"2012-02-21T12:08:16.000Z","duration":101937,"distance":845,"encoded_trace":null,"sport_type_id":9},{"id":9004230,"start_time":"2012-02-21T12:06:30.000Z","end_time":null,"duration":0,"distance":0,"encoded_trace":null,"sport_type_id":1},{"id":9004226,"start_time":"2012-02-21T12:06:18.000Z","end_time":null,"duration":0,"distance":0,"encoded_trace":null,"sport_type_id":5}],"meta":{"pagination":{"per_page":15,"available_pages":71,"total":1059,"page":"1","sort_by":"start_time","order":"desc"}}}""".getBytes("UTF-8")

You can try uJson, which is very fast and intuitive. No need for dedicated classes or implicit parsers. I have used it in multiple projects:

val json = ujson.read(Http("my_url").asString.body))
val tuples = json("run_sessions").arr /* <-- run_sessions is an array */ .map { item => 
    (item("id"), item("start_time"), item("end_time"), item("duration")) 
}

Using play.api.libs.json._ You can do it through implicits and case classes

Define the case-class like this:

import play.api.libs.json._

 case class Run_sessions(
  id: Double,
  start_time: String,
  end_time: Option[String],
  duration: Double,
  distance: Double,
  encoded_trace: Option[String],
  sport_type_id: Double
)
case class Pagination(
  per_page: Double,
  available_pages: Double,
  total: Double,
  page: String,
  sort_by: String,
  order: String
)
case class MetaBis(
  pagination: Pagination
)
case class RootJsonObject(
  run_sessions: List[Run_sessions],
  meta: MetaBis
)

Define some implicit Formats for the case classes:

object formatters {
implicit val a: Format[Run_sessions] = Json.format[Run_sessions]
implicit val b: Format[Pagination] = Json.format[Pagination]
implicit val c: Format[MetaBis] = Json.format[MetaBis]
implicit val d: Format[RootJsonObject] = Json.format[RootJsonObject]
}

Use validate to create the case-class from the Json

val json = Json.parse("""{

  "run_sessions": [
    {
      "id": 9003843,
      "start_time": "2012-02-22T10:59:06.000Z",
      "end_time": "2012-02-22T11:52:43.000Z",
      "duration": 3217769,
      "distance": 13644,
      "encoded_trace": null,
      "sport_type_id": 3
