@dbrumann / denis.brumann@sensiolabs.de 23 Encourage devs to depend on the HTTPlug interface instead of concrete clients. Provide good quality HTTP- related packages to the PHP community. Over time, make HTTPlug a PHP Standards Recommendation (PSR)

@dbrumann / denis.brumann@sensiolabs.de 24 The goal of this PSR is to allow developers to create libraries decoupled from HTTP client implementations. This will make libraries more reusable as it reduces the number of dependencies and lowers the likelihood of version conflicts.

@dbrumann / denis.brumann@sensiolabs.de 26 use Psr\Http\Client\ClientInterface; $response = $client->sendRequest($request); $request = $requestFactory->createRequest('GET', 'https://reqres.in/api/users'); use Psr\Http\Message\RequestFactoryInterface;

@dbrumann / denis.brumann@sensiolabs.de 32 A Client must not treat a well-formed HTTP request or HTTP response as an error condition.
