React Adapter

An HTTPlug adapter for the React Http client.

Installation

Use Composer_ to install the React adapter. It will also install React as it's a dependency.

$ composer require php-http/react-adapter

Usage

If you need control on the React instances, you can inject them during initialization:

use Http\Adapter\React\Client;

$systemDnsConfig = React\Dns\Config\Config::loadSystemConfigBlocking();
if (!$config->nameservers) {
    $config->nameservers[] = '8.8.8.8';
}

$dnsResolverFactory = new React\Dns\Resolver\Factory();
$dnsResolver = $factory->create($config);

$connector = new React\Socket\Connector([
    'dns' => $dnsResolver,
]);
$browser = new React\Http\Browser($connector);

$adapter = new Client($browser);

You can also use a ReactFactory in order to initialize React instances:

use Http\Adapter\React\ReactFactory;

$reactHttp = ReactFactory::buildHttpClient();

Then you can use the adapter 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);

Note that since v4 calling wait on HttpPromisePromise is expected to run inside a fiber:

use function React\Async\async;

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

    // Returns a Psr\Http\Message\ResponseInterface
    $response = $promise->wait();
})();
