Akka-HTTP服务器支持https

import java.io.InputStream
import java.security.{ SecureRandom, KeyStore }
import javax.net.ssl.{ SSLContext, TrustManagerFactory, KeyManagerFactory }

import akka.actor.ActorSystem
import akka.http.scaladsl.server.{ Route, Directives }
import akka.http.scaladsl.{ ConnectionContext, HttpsConnectionContext, Http }
import akka.stream.ActorMaterializer
import com.typesafe.sslconfig.akka.AkkaSSLConfig
implicit val system = ActorSystem()
implicit val mat = ActorMaterializer()
implicit val dispatcher = system.dispatcher

// Manual HTTPS configuration

val password: Array[Char] = "change me".toCharArray // do not store passwords in code, read them from somewhere safe!

val ks: KeyStore = KeyStore.getInstance("PKCS12")
val keystore: InputStream = getClass.getClassLoader.getResourceAsStream("server.p12")  
//数字证书是固定的p12文件格式

require(keystore != null, "Keystore required!")
ks.load(keystore, password)

val keyManagerFactory: KeyManagerFactory = KeyManagerFactory.getInstance("SunX509")
keyManagerFactory.init(ks, password)

val tmf: TrustManagerFactory = TrustManagerFactory.getInstance("SunX509")
tmf.init(ks)

val sslContext: SSLContext = SSLContext.getInstance("TLS")
sslContext.init(keyManagerFactory.getKeyManagers, tmf.getTrustManagers, new SecureRandom)
val https: HttpsConnectionContext = ConnectionContext.https(sslContext)

上面的2的https的代码也要调用
// you can run both HTTP and HTTPS in the same application as follows:
val commonRoutes: Route = get { complete("Hello world!") }
Http().bindAndHandle(commonRoutes, "127.0.0.1", 443, connectionContext = https)
Http().bindAndHandle(commonRoutes, "127.0.0.1", 80)
