OAuth2 Provider for Finagle

---------------------------

This is a [Finagle]-friendly version of [scala-oauth2-provider].

## 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.

```scala

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.

```scala

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

    }

}

```
