Question

我有这段简单的代码：

object Main {

  def main(args: Array[String]) {
    val application = new DefaultApplication(new File(args(0)), this.getClass.getClassLoader, null, Mode.Prod)
    Play.start(application)

    val test: Future[Int] = WS.url("http://www.bestattungsvergleich.de/go/" + URLEncoder.encode("Döhren", "UTF-8"))
      .withFollowRedirects(true)
      .withRequestTimeout(5000)
      .get()
      .map(x => {
        println(x.status)
        x.status
      })
      .recover { case e: Exception => {
        println(e.getMessage)
        1000
      }
    }
    println(Await.result(test, Duration.Inf))
    Play.stop()
  }
}

基本上我使用Play! WS utils从url获取http响应代码，问题是这个url有一个临时重定向（它返回307），当重定向url似乎不是编码，这是从catch子句打印的消息：

name contains non-ascii character: lp-loaded-variation-Dￃﾶhren

我还尝试过其他类型的编码（LATIN1，某些ISO），我做错了什么，或者是从Play!网络服务进行重定向检查时出现问题？< / p>

如wingedsubmariner所述，lp-loaded-variation-Dￃﾶhren作为Set-Cookie标头的一部分返回。

如果您遇到Play 2.2，可能会有所帮助，但这似乎适用于Play 2.3.6。添加“com.typesafe.play”%%“play-ws”％“2.3.6”到build.sbt

import java.net.URLEncoder
import play.api.libs.ws.ning._
import play.api.libs.ws._

object testing extends App {

  override def main(args: Array[String]) {
    implicit val context = play.api.libs.concurrent.Execution.Implicits.defaultContext
    val config = new NingAsyncHttpClientConfigBuilder(DefaultWSClientConfig()).build()
    val builder = new com.ning.http.client.AsyncHttpClientConfig.Builder(config)
    val wsClient: NingWSClient = new NingWSClient(builder.build())
    val result = wsClient.url("http://www.bestattungsvergleich.de/go/" + URLEncoder.encode("Döhren", "UTF-8"))
      .withRequestTimeout(3000)
      .withFollowRedirects(true)
      .get
      .map { response =>
        println("Got a response")
        println(response.body)
        // close out properly in real application not like this
        wsClient.underlying[com.ning.http.client.AsyncHttpClient].close;
        System.exit(0)
      }
      .recover {
        case e: Throwable =>
          println("error", e)
          println("Couldn't open")
      }
  }

}
