scala - 如何解决 Scala 调用中的 https 连接问题？

问题描述

我正在尝试下载我的 Facebook 个人资料图片。我成功地使用 oauth 来连接并获取所有正确的令牌，并被 facebook API 告知我的个人资料图片的 url。

但是，当我尝试检索它时，我收到有关连接异常的错误。它看起来像 sslhandler 中的东西，但我不确定。我已经包含了一些显示我如何下载图像的 scala 代码。如果我更改为http，我可以得到它，但是https失败。

在不同的服务器上进行更深入的研究表明问题是由于 SSL/TLS 验证造成的。

Sep 19 12:38:23 ip-172-31-24-217 server: 12:38:23.449 [New I/O worker #2] DEBUG c.n.h.c.p.n.NettyAsyncHttpProvider - Unexpected I/O exception on channel [id: 0x4b7d650e, /172.31.24.217:47572 => scontent-syd2-1.xx.fbcdn.net/157.240.8.23:443]
Sep 19 12:38:23 ip-172-31-24-217 server: org.jboss.netty.handler.ssl.NotSslRecordException: not an SSL/TLS record:

我正在使用 0.11.2 的数据绑定器调度。

构建.sbt

name := "url-test"

organization := "dev.undrewb"

version := "0.0.1"

scalaVersion := "2.11.12"

resolvers ++= Seq(
  "Sonatype scala-tools releases"  at "https://oss.sonatype.org/content/repositories/releases",
  "Sonatype scala-tools snapshots" at "https://oss.sonatype.org/content/repositories/snapshots"
)

libraryDependencies ++= {
  Seq(
    "net.databinder.dispatch" %% "dispatch-core" % "0.11.2"
  )
}

斯卡拉代码

import dispatch.Defaults._
import dispatch._
import scala.concurrent.Await
import scala.concurrent.duration._

  def fetchUrl( uri : String ) : Array[Byte] = {
         val svc = url(uri)
         val future_img = Http(svc OK as.Bytes)
         Await.result(future_img, Duration(1, "seconds"))
    
         future_img()
}

在我使用上面的 build.sbt 完成 sbt 控制台并粘贴上面的代码后，我得到以下信息 - 首先是 https 失败，然后是 http 工作
