Spray(8)REST API Project - Auth
6. How to Deal with Auth
My structure for this will be as follow:
/**
* 1 User(1, 'admin', ... , 'admin')
* 2 User(2, 'manager', ..., 'manager')
* 3 User(3, 'customer', ..., 'customer')
*/
caseclass User(id: Option[Long], userName: String, age: Int, userType: UserType.Value, createDate: DateTime, expirationDate: DateTime, password: String)

/**
* 1 Role(1, "admin", "")
* 2 Role(2, "manager", "")
* 3 Role(3, "customer", "")
*/
caseclass Role(id: Option[Long], roleCode: String, description: String)

/**
* 1. RUserRole(1, 1)
* 2. RUserRole(2, 2)
* 3. RUserRole(3, 3)
*/

caseclass RUserRole(roleId : Long, userId : Long)

Since we use basicHttpAuthority, the most important part is to get the data from the header
  def getToken(ctx: RequestContext): Option[UserPass] = {
    valauthHeader = ctx.request.headers.findByType[Authorization]
    valcredentials = authHeader.map { case Authorization(creds) => creds }
    credentials.flatMap {
      case BasicHttpCredentials(user, pass) => Some(UserPass(user, pass))
      case _ => None
    }

  }

Mock the user data for now
def auth(userName: String, password: String)(implicit session: Session) : Option[User] = {
      (userName, password) match {
        case ("admin","admin") => Option(User(Some(1), "admin", 100, UserType.ADMIN, new DateTime(), new DateTime(),"admin"))
        case ("customer","customer") => Option(User(Some(2), "customer", 100, UserType.CUSTOMER, new DateTime(), new DateTime(),"customer"))
        case ("manager","manager") => Option(User(Some(3), "manager", 100, UserType.SELLER, new DateTime(), new DateTime(),"manager"))
        case _ => None
      }

}

When we use that, it will be like this
trait URLRouterService extends HttpService with UsersAuthenticationDirectives {
authenticate(adminOnly) { user =>
…snip…
authenticate(customerOnly) { user =>
…snip...
authenticate(withRole("manager")) { user =>

The test specification class for this auth thing will be look like this>
package com.sillycat.easysprayrestserver.actor

import org.specs2.mutable.Specification
import spray.testkit.Specs2RouteTest
import spray.http._
import StatusCodes._
import spray.http.BasicHttpCredentials
import spray.http.HttpHeaders.Authorization
import spray.routing.AuthenticationFailedRejection
import spray.routing.AuthenticationRequiredRejection
import spray.routing.HttpService
import spray.routing.RequestContext
import spray.routing.authentication.Authentication
import spray.routing.authentication.UserPass
import spray.util.executionContextFromActorRefFactory
import spray.util.pimpSeq

class URLRouterActorSpec extends Specification with Specs2RouteTest with URLRouterService {

  def actorRefFactory = system

  "The URLRouterActor" should {

    "Anyone can visit this page." in {
      Get("/v1/sillycat/resource/all") ~> route ~> check { entityAs[String] must contain("Morning") }
    }

    "Admin can visit this page." in {
      Get("/v1/sillycat/resource/admin-only") ~> addCredentials(BasicHttpCredentials("admin", "admin")) ~> route ~> check { entityAs[String] must contain("Morning") }
    }

    "No UserName Password can not visit this page." in {
      Get("/v1/sillycat/resource/admin-only") ~> route ~> check {
      rejection === AuthenticationRequiredRejection("https", "sillycat")
      }
    }
   
    "Wrong UserName Password can not visit this page." in {
      Get("/v1/sillycat/resource/admin-only") ~> addCredentials(BasicHttpCredentials("admin", "asdfadsf")) ~> route ~> check {
      rejection === AuthenticationFailedRejection("sillycat")
      }
    }

  }


}

Tips:
1. Log Error
Error Message:
app[ERROR]: May 1, 2013 1:57:26 PM com.mchange.v2.log.MLog <clinit>
app[ERROR]: INFO: MLog clients using java 1.4+ standard logging.

Solution:

2. JRebel
The purpose for this is to enable hot reloading.
Follow the document here https://github.com/spray/sbt-revolver
Visit this website to get a free license https://my.jrebel.com/plans/

We can see the information here https://my.jrebel.com/account/my-dashboard

And get the license from here https://my.jrebel.com/account/how-to-activate
  
Download the latest package named rebel-5.2.2-nosetup.zip

Unzip this file and place in the directory /Users/carl/tool/jrebel
Link it to the working directory
>sudo ln -s /Users/carl/tool/jrebel /opt/jrebel

Run the active command
>cd /opt/jrebel/bin
>./jrebel-config.sh

After that, make sbt-revoler find that plugin
>vi ~/.profile
export JREBEL_PATH=/opt/jrebel/jrebel.jar
>. ~/.profile

That is it. We do not need to re-start our spray server now.
