> ------------------------------------------------
>
> Key: HTTPCLIENT-1435
> URL: https://issues.apache.org/jira/browse/HTTPCLIENT-1435
> Project: HttpComponents HttpClient
> Issue Type: Bug
> Components: Fluent HC
> Affects Versions: 4.3.1
> Environment: Win7 + JDK6 + HttpClient 4.3.1 + HttpCore 4.3
> Reporter: Remis
> Fix For: 4.3.2
>
>
> The sample code below demonstrates the issue:
> package com.test;
> import org.apache.http.HttpHost;
> import org.apache.http.auth.AuthScope;
> import org.apache.http.auth.UsernamePasswordCredentials;
> import org.apache.http.client.CredentialsProvider;
> import org.apache.http.client.config.RequestConfig;
> import org.apache.http.client.fluent.Executor;
> import org.apache.http.client.fluent.Request;
> import org.apache.http.client.methods.HttpPost;
> import org.apache.http.impl.client.BasicCredentialsProvider;
> import org.apache.http.impl.client.HttpClientBuilder;
> public class Test {
> public static void main(final String[] args) {
> final HttpHost proxy = new HttpHost("my-proxy.com", 8080);
> final String username = "username";
> final String password = "password";
> final String uri = "https://www.my-uri.com/servlet/action";;
> // WORKS: HTTP/1.1 200 OK
> final CredentialsProvider credsProvider = new
> BasicCredentialsProvider();
> credsProvider.setCredentials(new AuthScope(proxy), new
> UsernamePasswordCredentials(username, password));
> final HttpPost httppost = new HttpPost(uri);
> httppost.setConfig(RequestConfig.custom().setProxy(proxy).build());
> try {
>
> System.out.println(HttpClientBuilder.create().setDefaultCredentialsProvider(credsProvider).build()
> .execute(httppost).getStatusLine());
> } catch (final Exception e) {
> e.printStackTrace();
> }
> // WORKS: as expected: HTTP/1.1 407 Proxy Authentication Required
> try {
>
> System.out.println(Request.Post(uri).viaProxy(proxy).execute().returnResponse().getStatusLine());
> } catch (final Exception e) {
> e.printStackTrace();
> }
> // FAILS (not expected): java.net.UnknownHostException:
> try {
> final Executor executor = Executor.newInstance().auth(proxy,
> username, password).authPreemptive(proxy);
>
> System.out.println(executor.execute(Request.Post(uri).viaProxy(proxy)).returnResponse().getStatusLine());
> } catch (final Exception e) {
> e.printStackTrace();
> }
> }
> }
