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
.
Installation
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
Usage
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);
Note
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', 'http://httpbin.org');
// Returns a Psr\Http\Message\ResponseInterface
$response = $adapter->sendRequest($request);
Or send asynchronous ones:
use GuzzleHttp\Psr7\Request;
$request = new Request('GET', 'http://httpbin.org');
// Returns a Http\Promise\Promise
$promise = $adapter->sendAsyncRequest(request);
