Http Basic Authentication in Java using HttpClient?

Have you tried this (using HttpClient version 4):

String encoding = Base64Encoder.encode(user + ":" + pwd);HttpPost httpPost = new HttpPost("http://host:post/test/login");httpPost.setHeader(HttpHeaders.AUTHORIZATION, "Basic " + encoding);System.out.println("executing request " + httpPost.getRequestLine());HttpResponse response = httpClient.execute(httpPost);HttpEntity entity = response.getEntity();

Ok so this one works. Just in case anybody wants it, here's the version that works for me :)

import java.io.BufferedReader;import java.io.InputStream;import java.io.InputStreamReader;import java.net.HttpURLConnection;import java.net.URL;import java.util.Base64;public class HttpBasicAuth {    public static void main(String[] args) {        try {            URL url = new URL ("http://ip:port/login");            String encoding = Base64.getEncoder().encodeToString(("test1:test1").getBytes(‌"UTF‌​-8"​));            HttpURLConnection connection = (HttpURLConnection) url.openConnection();            connection.setRequestMethod("POST");            connection.setDoOutput(true);            connection.setRequestProperty  ("Authorization", "Basic " + encoding);            InputStream content = (InputStream)connection.getInputStream();            BufferedReader in   =                 new BufferedReader (new InputStreamReader (content));            String line;            while ((line = in.readLine()) != null) {                System.out.println(line);            }        } catch(Exception e) {            e.printStackTrace();        }    }}

This is the code from the accepted answer above, with some changes made regarding the Base64 encoding. The code below compiles.

import java.io.BufferedReader;import java.io.InputStream;import java.io.InputStreamReader;import java.net.HttpURLConnection;import java.net.URL;import org.apache.commons.codec.binary.Base64;public class HttpBasicAuth {    public static void main(String[] args) {        try {            URL url = new URL ("http://ip:port/login");            Base64 b = new Base64();            String encoding = b.encodeAsString(new String("test1:test1").getBytes());            HttpURLConnection connection = (HttpURLConnection) url.openConnection();            connection.setRequestMethod("POST");            connection.setDoOutput(true);            connection.setRequestProperty  ("Authorization", "Basic " + encoding);            InputStream content = (InputStream)connection.getInputStream();            BufferedReader in   =                 new BufferedReader (new InputStreamReader (content));            String line;            while ((line = in.readLine()) != null) {                System.out.println(line);            }        }         catch(Exception e) {            e.printStackTrace();        }    }}
