Sample Guzzle 6 request to Drupal 8 using OAuth 1

README.md

This script helps you to test OAuth-signed requests against Drupal 8.

First, make sure that Drupal has been configured by following the steps at https://www.drupal.org/node/2110825. Then install this script with these steps:

1. Clone this gist.
2. Run composer.install.
3. Open oauth_request.php and fill out your consumer_key and consumer_secret. Then Adjust base_uri.
4. Execute the script with php oauth_request.php.

NOTE: I had to apply this patch to Guzzle's OAuth Subscriber or authentication would fail.

composer.json

{
   "require": {
      "guzzlehttp/guzzle": "~6.0",
      "guzzlehttp/oauth-subscriber": "0.3.*"
   }
}

oauth_request.php

<?php
/**
 * @file oauthRequest.php
 * Performs an OAuth request to retrieve a node.
 */

// Note: the following require is only needed if you want to run this
// code as a standalone script. If you are running this within a Drupal
// environment, then remove the following line, since Drupal does this
// for you already.
require 'vendor/autoload.php';

use GuzzleHttp\Client;
use GuzzleHttp\HandlerStack;
use GuzzleHttp\Subscriber\Oauth\Oauth1;

$stack = HandlerStack::create();

$middleware = new Oauth1([
  'consumer_key'    => 'my-consumer-key',
  'consumer_secret' => 'my-consumer-secret',
]);
$stack->push($middleware);

$client = new Client([
  'base_uri' => 'http://d8.local',
  'handler' => $stack,
]);

// Set the "auth" request option to "oauth" to sign using oauth
$response = $client->get('node/1?_format=json', ['auth' => 'oauth', 'debug' => true]);
$body = $response->getBody();
print_r(json_decode((string) $body));
