Play Json

• API Documentation

libraryDependencies += "com.github.jwt-scala" %% "jwt-play-json" % "10.0.2"

Basic usage

copysourceimport java.time.Clock

import pdi.jwt._
import play.api.libs.json.Json

implicit val clock: Clock = Clock.systemUTC

val claim = Json.obj(("user", 1), ("nbf", 1431520421))
val key = "secretKey"
val algo = JwtAlgorithm.HS256

JwtJson.encode(claim)

val token = JwtJson.encode(claim, key, algo)

JwtJson.decodeJson(token, key, Seq(JwtAlgorithm.HS256))

JwtJson.decode(token, key, Seq(JwtAlgorithm.HS256))

Encoding

copysourceval header = Json.obj(("typ", "JWT"), ("alg", "HS256"))
// From just the claim to all possible attributes
JwtJson.encode(claim)
JwtJson.encode(claim, key, algo)
JwtJson.encode(header, claim, key)

Decoding

copysource// You can decode to JsObject
JwtJson.decodeJson(token, key, Seq(JwtAlgorithm.HS256))
JwtJson.decodeJsonAll(token, key, Seq(JwtAlgorithm.HS256))
// Or to case classes
JwtJson.decode(token, key, Seq(JwtAlgorithm.HS256))
JwtJson.decodeAll(token, key, Seq(JwtAlgorithm.HS256))

Formating

The project provides implicit reader and writer for both JwtHeader and JwtClaim

copysourceimport pdi.jwt.JwtJson._

// Reads
Json.fromJson[JwtHeader](header)
Json.fromJson[JwtClaim](claim)

// Writes
Json.toJson(JwtHeader(JwtAlgorithm.HS256))
Json.toJson(JwtClaim("""{"user":1}""").issuedNow.expiresIn(10))
// Or
JwtHeader(JwtAlgorithm.HS256).toJsValue()
JwtClaim("""{"user":1}""").issuedNow.expiresIn(10).toJsValue()
