java - 为什么 dispatch 会针对特定 URL 抛出 "java.net.ConnectException: General SSLEngine ..."和 "unexpected status"异常？

Question

我有以下无效代码:

object Main extends App {
  import dispatch._

  def test(address: String) = {
    Await.result(Http.default(url(address).GET OK as.String), Duration.Inf)
  }

  // This works fine
  val s1 = test("http://download.finance.yahoo.com/d/quotes.csv?s=MSFT&f=sohgbav")
  println(s1)

  // This throws Exception 1
  val s2 = test("http://www.alphavantage.co/query?function=TIME_SERIES_DAILY_ADJUSTED&symbol=MSFT&apikey=demo&datatype=csv")
  println(s2) 

  // This throws Exception 2
  val s3 = test("https://www.alphavantage.co/query?function=TIME_SERIES_DAILY_ADJUSTED&symbol=MSFT&apikey=demo&datatype=csv")
  println(s3) 
}

我想知道为什么“s1”工作正常，而“s2”和“s3”抛出异常。抛出的异常是:

异常(exception)情况 1:

[error]   ! access URL
[error]    java.util.concurrent.ExecutionException: dispatch.StatusCode: Unexpected response status: 301 (NettyResponseFuture.java:172)
[error] org.asynchttpclient.netty.NettyResponseFuture.get(NettyResponseFuture.java:172)
[error] dispatch.HttpExecutor.$anonfun$apply$3(execution.scala:123) 

异常(exception) 2:

[error]   ! access URL
[error]    java.util.concurrent.ExecutionException: java.net.ConnectException: General SSLEngine problem (NettyResponseFuture.java:172)
[error] org.asynchttpclient.netty.NettyResponseFuture.get(NettyResponseFuture.java:172)
[error] dispatch.HttpExecutor.$anonfun$apply$3(execution.scala:123)

此外，当我通过 Safari 网络浏览器访问所有三个 URL 时，它们都按预期工作。为什么第一个 URL 通过调度工作正常，但最后两个却不行？

如果您想信任所有证书，如链接的 Play 示例中所示，请尝试以下操作:

Http.withConfiguration(config => config.setAcceptAnyCertificate(true))(url(address).GET OK as.String)
