我正在尝试使用Akka Http客户端向REST Web服务发出GET请求。Akka Http客户端在HttpRequest上设置Cookie
我无法弄清楚如何在进行GET之前在请求上设置cookie。
我搜索了网页,并找到了在服务器端读取cookie的方法。但我找不到任何告诉我如何在客户端请求上设置Cookie的内容。
根据我自己的研究,我尝试了以下方法来设置HTTP请求
import akka.actor.ActorSystem
import akka.http.scaladsl.Http
import akka.http.scaladsl.model._
import akka.http.scaladsl.unmarshalling.Unmarshal
import akka.stream.scaladsl.{Sink, Source}
import akka.http.scaladsl.marshallers.sprayjson.SprayJsonSupport
import akka.http.scaladsl.model.headers.HttpCookie
import akka.stream.ActorMaterializer
import spray.json._
import scala.util.{Failure, Success}
case class Post(postId: Int, id: Int, name: String, email: String, body: String)
trait JsonSupport extends SprayJsonSupport with DefaultJsonProtocol {
implicit val postFormat = jsonFormat5(Post.apply)
}
object AkkaHttpClient extends JsonSupport{
def main(args: Array[String]) : Unit = {
val cookie = headers.`Set-Cookie`(HttpCookie(name="foo", value="bar"))
implicit val system = ActorSystem("my-Actor")
implicit val actorMaterializer = ActorMaterializer()
implicit val executionContext = system.dispatcher
val mycookie = HttpCookie(name="foo", value="bar")
val httpClient = Http().outgoingConnection(host = "jsonplaceholder.typicode.com")
val request = HttpRequest(uri = Uri("/comments"), headers = List(cookie))
val flow = Source.single(request)
.via(httpClient)
.mapAsync(1)(r => Unmarshal(r.entity).to[List[Post]])
.runWith(Sink.head)
flow.andThen {
case Success(list) => println(s"request succeded ${list.size}")
case Failure(_) => println("request failed")
}.andThen {
case _ => system.terminate()
}
}
}
一个cookie但是这给出了一个错误
[WARN] [08/05/2016 10:50:11.134] [my-Actor-akka.actor.default-dispatcher-3] [akka.actor.ActorSystemImpl(my-Actor)]
HTTP header 'Set-Cookie: foo=bar' is not allowed in requests
'设置Cookie'是响应头。对于请求标题,请使用标题名称“Cookie”(请参阅https://en.wikipedia.org/wiki/HTTP_cookie#Setting_a_cookie)。 – devkat
