Detect protocol with finatra

Question

Hello I'm faily new with Finatra and wanted to know if there is a way to validate that a request was made using the https protocol?

Answer 1

If you want to always use HTTPS you can disable the http server server

import com.twitter.finagle.Http
import com.twitter.finatra.http.HttpServer
import com.twitter.finatra.http.routing.HttpRouter

object ExampleHttpsServerMain extends ExampleHttpsServer

class ExampleHttpsServer
  extends HttpServer
  with Tls {

  override val defaultHttpPort: String = "" // disable the default HTTP port
  override val defaultHttpsPort: String = ":443"

  override def configureHttp(router: HttpRouter): Unit = {
    router
      .add[ExampleController]
  }
}

But if you want for some specific controller or route to check if it is https for example Login should only be used via https then you can define Filters for example:

Per Route

class ExampleController @Inject()(
  exampleService: ExampleService
) extends Controller {

  filter[ExampleFilter].get("/ping") { request: Request =>
    "pong"
  }

  filter[ExampleFilter]
    .filter[AnotherExampleFilter]
    .get("/name") { request: Request =>
    response.ok.body("Bob")
  }

  filter(new OtherFilter).post("/foo") { request: Request =>
    exampleService.do(request)
    "bar"
  }
}

Per Controller

import DoEverythingModule
import ExampleController
import ExampleFilter
import com.twitter.finagle.http.Request
import com.twitter.finatra.http.filters.AccessLoggingFilter
import com.twitter.finatra.http.routing.HttpRouter
import com.twitter.finatra.http.{Controller, HttpServer}

object ExampleServerMain extends ExampleServer

class ExampleServer extends HttpServer {

  override val modules = Seq(
    DoEverythingModule)

  override def configureHttp(router: HttpRouter) {
    router
      .add[ExampleFilter, ExampleController]
  }
}

If you check all implementations of SimpleFilter you may find some filters that you can reuse or base your filter from.
