User Guide

1. Implement com.twitter.finagle.oauth2.DataHandler using your own data store (in-memory, DB, etc).
2. Use com.twitter.finagle.OAuth2 API to authorize requests and issue access tokens.

A service that emits OAuth2 access tokens based on request's credentials.

import com.twitter.finagle.OAuth2
import com.twitter.finagle.oauth2.{OAuthError, DataHandler}

import com.twitter.finagle.http.{Request, Response, Version, Status}
import com.twitter.finagle.Service
import com.twitter.util.Future

val dataHandler: DataHandler[?] = ???

object TokenService extends Service[Request, Response] with OAuth2 {
  def apply(req: Request): Future[Response] =
    issueAccessToken(req, dataHandler).flatMap { token =>
      val rep = Response(Version.Http11, Status.Ok)
      rep.setContentString(token.accessToken)
      Future.value(rep)
    } handle {
      case e: OAuthError => e.toResponse
    }
}

A service that checks whether the request contains a valid token.

import com.twitter.finagle.OAuth2
import com.twitter.finagle.oauth2.{OAuthError, DataHandler}

import com.twitter.finagle.http.{Request, Response, Version, Status}
import com.twitter.finagle.Service
import com.twitter.util.Future

object ProtectedService extends Service[Request, Response] with OAuth2 {
  def apply(req: Request): Future[Response] =
    authorize(req, dataHandler).flatMap { authInfo =>
      val rep = Response(Version.Http11, Status.Ok)
      rep.setContentString(s"Hello ${authInfo.user}!")
      Future.value(rep)
    } handle {
      case e: OAuthError => e.toResponse
    }
}
