我有以下非工作代码:
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”则抛出异常。抛出的异常是:
例外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$3(execution.scala:123)
例外2:
[error] ! access URL
[error] java.util.concurrent.ExecutionException: java.net.ConnectException: General SSLEngine problem (NettyResponseFuture.java:172)
[error] org.asynchttpclient.netty.NettyResponseFuture.get(NettyResponseFuture.java:172)
[error] dispatch.HttpExecutor.$anonfun$apply$3(execution.scala:123)
此外,当我通过Safari Web浏览器访问它们时,所有三个URL都按预期工作。为什么第一个URL通过发送工作正常,但最后两个没有?

如果您想信任所有证书,例如在链接的Play示例中,请尝试以下操作:
Http.withConfiguration(config => config.setAcceptAnyCertificate(true))(url(address).GET OK as.String)

要创建一个验证证书的Http客户端,我在这里找到了一些示例代码:https://kevinlocke.name/bits/2012/10/03/ssl-certificate-verification-in-dispatch-and-asynchttpclient/。
