Guzzle 7 Adapter

An HTTPlug adapter for the Guzzle 7 HTTP client. Guzzle 7 supports PSR-18 out of the box. This adapter makes sense if you want to use HTTPlug async interface or to use Guzzle 7 with a library that did not upgrade to PSR-18 yet and depends on php-http/client-implementation.


To install the Guzzle adapter, which will also install Guzzle itself (if it was not yet included in your project), run:

$ composer require php-http/guzzle7-adapter


To create a Guzzle7 adapter you should use the createWithConfig() function. It will let you to pass Guzzle configuration to the client:

use Http\Adapter\Guzzle7\Client as GuzzleAdapter;

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


If you want even more control over your Guzzle object, you may give a Guzzle client as first argument to the adapter’s constructor:

use GuzzleHttp\Client as GuzzleClient;
use Http\Adapter\Guzzle7\Client as GuzzleAdapter;

$config = ['timeout' => 5];
// ...
$guzzle = new GuzzleClient($config);
// ...
$adapter = new GuzzleAdapter($guzzle);

If you pass a Guzzle instance to the adapter, make sure to configure Guzzle to not throw exceptions on HTTP error status codes, or this adapter will violate PSR-18.

And use it to send synchronous requests:

use GuzzleHttp\Psr7\Request;

$request = new Request('GET', '');

// Returns a Psr\Http\Message\ResponseInterface
$response = $adapter->sendRequest($request);

Or send asynchronous ones:

use GuzzleHttp\Psr7\Request;

$request = new Request('GET', '');

// Returns a Http\Promise\Promise
$promise = $adapter->sendAsyncRequest(request);
