Previously I have setup a a Drupal 8 which is RESTful ready.

• Drupal 8 – Setup the RESTful Service @ 1

Guzzle is a PHP HTTP client & framework for building RESTful web service clients. In this example, we would create a simple .php to fetch a node from Drupal 8.

1. Make sure you have the Composer installed. You can refer to my previous post.

• Composer – Manage your PHP dependencies

2. Create the composer.json in your webroot.

{
  "name": "eureka/test-composer",
  "require": {
    "php": ">=5.3.2",
    "guzzle/guzzle": "*"
  }
}

3. Download the dependencies by running the following command in shell.

composer install

4. Create the index.php.

<?php
  require 'vendor/autoload.php';
  use Guzzle\Http\Client;

  $client = new Client('http://drupal8.localhost.com');
  // If in a Drupal environment use the HTTP client service.
  //$client = Drupal::httpClient()->setBaseUrl(''<server url>');

  $request = $client->get('entity/node/1');
  $request->addHeader('Accept', 'application/json');
  $response = $request->send()->json();

  print '<pre>';
  print_r($response);
  print '</pre>';
?>

5. Open the index.php in browser and check if your RESTful call works or not.

 

6. Again, you could get a JSON in HAL response by modifying your request header. This is required in POST request for Drupal 8.

<?php
  require 'vendor/autoload.php';
  use Guzzle\Http\Client;

  $client = new Client('http://drupal8.localhost.com');
  // If in a Drupal environment use the HTTP client service.
  //$client = Drupal::httpClient()->setBaseUrl('<server url>');

  $request = $client->get('entity/node/1');
  $request->addHeader('Accept', 'application/hal+json');
  $response = $request->send()->json();

  print '<pre>';
  print_r($response);
  print '</pre>';
?>

Done =)
