README

This is a simple wrapper on Guzzle 6 to access and use the API provided by drupal.org. It was built for DruStats which was built for a developer contest in DrupalCon Asia. You can refer to DruStats for example usage.

Installation

Use composer to install the package.

composer require hussainweb/drupal-api-client:"^2.0"

Drupal API client version 2+ no longer depends on Guzzle. It can work with any HTTP client that implements a HTTPlug compatible ClientInterface. Here's a list of providers.

For example, to use Guzzle, you would need the Guzzle 6 adapter. This will install Guzzle 6 as well.

composer require php-http/guzzle6-adapter

Usage

The library provides a single client and multiple request classes to send requests to drupal.org API. To send a request, create a request object and call the getEntity method on the client class.

use Http\Adapter\Guzzle6\Client as GuzzleAdapter;
use Hussainweb\DrupalApi\Client;
use Hussainweb\DrupalApi\Request\UserRequest;

$config = [
    'timeout' => 2,
    // 'handler' => ...
    // ...
];
$adapter = GuzzleAdapter::createWithConfig($config);

// Retrieve user with uid 314031.
$client = new Client($adapter);
$user_request = new UserRequest('314031');
$user = $client->getEntity($user_request);

The above example uses Guzzle 6 Adapter but any HTTP client implementing php-http based clients will work. Construct the HTTP client and pass it when constructing the Hussainweb\DrupalApi\Client class.

There are various request classes to retrieve different types of entities and entity listings. Many of the entity request classes have a corresponding list request class as well, e.g. CommentRequest and CommentCollectionRequest.

User Agent

In accordance with responsible usage of Drupal.org API, it is important to set the user-agent header to indicate your application. You may set this request once globally using the static property on the Request class.

Request::$userAgent = 'Drupal Statistics Collector';

You have to do this only once as this user-agent is applied to all child requests as well. See the test in \Hussainweb\DrupalApi\Tests\Request\RequestTest::testRequestUserAgent for verifying the behaviour.

Note on HTTP client implementations

As noted above, Drupal API Client version 2+ no longer depends on Guzzle but any HTTP client which provides a php-http/client-implementation. This is a PSR-18 compatible HTTP client interface and you can read more about it at HTTPlug.

Since PSR-18 has been implemented in a different provider (psr/http-client-implementation), this client might move to that in the near future. Right now, almost all clients that support the HTTPlug interface also supports the PSR-18 interface and you would be able to use that client right now. The only notable exception is Guzzle 7 but there is discussion to add support for that in an adapter.
