i've a json like this.
certificates: [{type: "abc",file: {name: "xyz",path:"/usr/local",extension: "csv"}} , {type: "xyz",file: {name: "xyz",path: "/usr/local",extension: "csv"}} , {type: "nmo",file: {name: "xyz",path: "/usr/local",extension: "csv"}}]
this solution isn't working in my case.
var list = (jsonValue \ "certificates").as[List[Map[String,String]]]
Can some suggest how to parse this?
with Play JSON:
case class CertFile(name: String, path: String, extension: String)
case class Certificate(certType: String, certFile: CertFile)
implicit val certFile: Reads[CertFile] = (
(JsPath \ "name").read[String] and
(JsPath \ "path").read[String] and
(JsPath \ "extension").read[String]
) (CertFile.apply _)
implicit val cert: Reads[Certificate] = (
(JsPath \ "type").read[String] and
(JsPath \ "file").read[CertFile]
) (Certificate.apply _)
and you can use this way:
val json =
"""{ "certificates": [{"type": "abc","file": {"name": "xyz","path":"/usr/local","extension": "csv"}} , {"type": "xyz","file": {"name": "xyz","path": "/usr/local","extension": "csv"}} , {"type": "nmo","file": {"name": "xyz","path": "/usr/local","extension": "csv"}}] }"""
val jsonValue = Json.parse(json)
val list = (jsonValue \ "certificates").as[List[Certificate]]
A small addition to the answer, You'll have to import the following to get this to work:
import play.api.libs.json._ // JSON library
import play.api.libs.json.Reads._ // Custom validation helpers
import play.api.libs.functional.syntax._ // Combinator syntax
As mentioned in the SDK: https://www.playframework.com/documentation/2.6.x/ScalaJsonCombinators
