如何使用Scala/Akka Http处理多个HTTP标头

libraryDependencies += "com.typesafe.akka" %% "akka-http" % "2.6.16"

import akka.http.scaladsl.server.Directives._

val route = get {
  optionalHeaderValueByName("Header1") { header1 =>
    optionalHeaderValueByName("Header2") { header2 =>
      complete(s"Header1: $header1, Header2: $header2")
    }
  }
}

import akka.actor.ActorSystem
import akka.http.scaladsl.Http
import akka.stream.ActorMaterializer

implicit val system = ActorSystem()
implicit val materializer = ActorMaterializer()
implicit val executionContext = system.dispatcher

val bindingFuture = Http().bindAndHandle(route, "localhost", 8080)

curl -X GET http://localhost:8080 -H "Header1: Value1" -H "Header2: Value2"

Header1: Some(Value1), Header2: Some(Value2)
