Question

我想将http请求发布到具有给定ca证书的安全服务器。

我正在使用Spray 1.3.1，代码看起来像这样：

val is = this.getClass().getResourceAsStream("/cacert.crt")

val cf: CertificateFactory = CertificateFactory.getInstance("X.509")

val caCert: X509Certificate = cf.generateCertificate(is).asInstanceOf[X509Certificate];

val tmf: TrustManagerFactory  = TrustManagerFactory.getInstance(TrustManagerFactory.getDefaultAlgorithm());
val ks: KeyStore = KeyStore.getInstance(KeyStore.getDefaultType());
ks.load(null); 
ks.setCertificateEntry("caCert", caCert);

tmf.init(ks);

implicit val sslContext: SSLContext = SSLContext.getInstance("TLS");
sslContext.init(null, tmf.getTrustManagers(), null);

implicit val timeout: Timeout = Timeout(15.seconds)
import spray.httpx.RequestBuilding._

val respFuture = (IO(Http) ? Post( uri=Uri(url), content="my content")).mapTo[HttpResponse]

问题是没有采用定义的隐式SSLContext，我得到：“无法在运行时找到有效的证书路径”。

如何定义与喷雾客户端一起使用的SSLContext？

Answer 1

我使用以下命令在spray中定义SSLContext。就我而言，我使用的是非常宽松的上下文，不会验证远程服务器的证书。基于this post中的第一个解决方案 - 对我有用。

import java.security.SecureRandom
import java.security.cert.X509Certificate
import javax.net.ssl.{SSLContext, X509TrustManager, TrustManager}

import akka.actor.ActorRef
import akka.io.IO
import akka.util.Timeout
import spray.can.Http

import scala.concurrent.Future

trait HttpClient {
  /** For the HostConnectorSetup ask operation. */
  implicit val ImplicitPoolSetupTimeout: Timeout = 30 seconds

  val hostName: String
  val hostPort: Int

  implicit val sslContext = {
    /** Create a trust manager that does not validate certificate chains. */
    val permissiveTrustManager: TrustManager = new X509TrustManager() {
      override def checkClientTrusted(chain: Array[X509Certificate], authType: String): Unit = {
      }
      override def checkServerTrusted(chain: Array[X509Certificate], authType: String): Unit = {
      }
      override def getAcceptedIssuers(): Array[X509Certificate] = {
        null
      }
    }

    val initTrustManagers = Array(permissiveTrustManager)
    val ctx = SSLContext.getInstance("TLS")
    ctx.init(null, initTrustManagers, new SecureRandom())
    ctx
  }

  def initClientPool(): Future[ActorRef] = {
    val hostPoolFuture = for {
      Http.HostConnectorInfo(connector, _) <- IO(Http) ? Http.HostConnectorSetup(hostName, port = hostPort,
        sslEncryption = true)
    } yield connector
  }
}

我想出了sendReceive的替代品，允许传递自定义SSLContext（作为implicit）

def mySendReceive( request: HttpRequest )( implicit uri: spray.http.Uri, ec: ExecutionContext, futureTimeout: Timeout = 60.seconds, sslContext: SSLContext = SSLContext.getDefault): Future[ HttpResponse ] = {

    implicit val clientSSLEngineProvider = ClientSSLEngineProvider { _ =>
        val engine = sslContext.createSSLEngine( )
        engine.setUseClientMode( true )
        engine
    }

    for {
        Http.HostConnectorInfo( connector, _ ) <- IO( Http ) ? Http.HostConnectorSetup( uri.authority.host.address, port = uri.authority.port, sslEncryption = true )
        response <- connector ? request
    } yield response match {
        case x: HttpResponse ⇒ x
        case x: HttpResponsePart ⇒ sys.error( "sendReceive doesn't support chunked responses, try sendTo instead" )
        case x: Http.ConnectionClosed ⇒ sys.error( "Connection closed before reception of response: " + x )
        case x ⇒ sys.error( "Unexpected response from HTTP transport: " + x )
    }
}

然后将其用作＆＃34;通常＆＃34; （几乎见下文）：

val pipeline: HttpRequest => Future[ HttpResponse ] = mySendReceive
pipeline( Get( uri ) ) map processResponse

我真的有几件事情不喜欢：

这是一个黑客攻击。我希望spray-client能够原生地支持自定义SSLContext。这些在开发和测试期间非常有用，通常强制自定义TrustManagers
有一个implicit uri: spray.http.Uri参数可以避免连接器上主机和端口的硬编码。因此uri必须声明为implicit。

对此代码的任何改进，甚至更好，spray-client的补丁，都是最受欢迎的（SSLEngine创建的外部化是显而易见的）

我开始工作的最短时间是：

IO(Http) ! HostConnectorSetup(host = Conf.base.getHost, port = 443, sslEncryption = true)

即。 @ reed-sandberg的回答是什么，但似乎不需要问问模式。我没有将连接参数传递给sendReceive，而是：

// `host` is the host part of the service
//
def addHost = { req: HttpRequest => req.withEffectiveUri(true, Host(host, 443)) }

val pipeline: HttpRequest => Future[Seq[PartitionInfo]] = (
    addHost
    ~> sendReceive
    ~> unmarshal[...]
)

这似乎有效，但我很自然会想知道这种方法是否有缺点。

我同意所有喷涂客户端SSL支持批评。像这样的事情是如此艰难，这很尴尬。我可能花了两天时间来合并来自不同来源的数据（SO，喷雾文档，邮件列表）。
