Question

I’m trying to execute (in IntelliJ IDE or from sbt command-line) this very basic dispatch snippet from behind a proxy :

import dispatch._
val svc = url("http://api.hostip.info/country.php")
val country = Http(svc > as.String)
println(country())

and all I can get is an exception :

java.net.ConnectException: Connection timed out: no further information to
    http://api.hostip.info/country.php java.util.concurrent.ExecutionException:
       java.net.ConnectException: Connection timed out: no further information 
            to http://api.hostip.info/country.php

I tried with no conclusive result to set the usual vm parameters :
-Dhttp.proxyHost=_my_proxy_host_ -Dhttp.proxyPort=80
and still got the same exception.

On the other hand, the following snippet does work well :

import dispatch._
val svc = url("http://api.hostip.info/country.php") setProxyServer(new com.ning.http.client.ProxyServer(myproxyhost,80))
val country = Http(svc > as.String)
println(country())

Since it does not seem quite aesthetic nor scala-ish, I wonder if it is really what I am supposed to do in such a case.

Any help would be welcome, thanks in advance.

http.proxyHost and http.proxyPort will be used if you set this parameter:

-Dcom.ning.http.client.AsyncHttpClientConfig.useProxyProperties=true

Additionaly there are parameters:

-Dcom.ning.http.client.AsyncHttpClientConfig.proxy.user=user
-Dcom.ning.http.client.AsyncHttpClientConfig.proxy.password=password
-Dcom.ning.http.client.AsyncHttpClientConfig.proxy.protocol=NTLM
