1. Overview

This tutorial will illustrate how to configure Basic Authentication on the Apache HttpClient 4.

2. Basic Authentication with the API

Let’s start with the standard way of configuring Basic Authentication on the HttpClient – via a CredentialsProvider:

CredentialsProvider provider = new BasicCredentialsProvider();
UsernamePasswordCredentials credentials = new UsernamePasswordCredentials("user1", "user1Pass");
provider.setCredentials(AuthScope.ANY, credentials);
HttpClient client = HttpClientBuilder.create().setDefaultCredentialsProvider(provider).build();

HttpResponse response = client.execute(new HttpGet(URL_SECURED_BY_BASIC_AUTHENTICATION));
int statusCode = response.getStatusLine().getStatusCode();
assertThat(statusCode, equalTo(HttpStatus.SC_OK));

As you can see, creating the client with a credentials provider to set it up with Basic Authentication is not difficult.
