@dbrumann / [email protected] 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 / [email protected] 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 / [email protected] 25 $request = new Request('GET', 'https://reqres.in/api/users'); use GuzzleHttp\Psr7\Request; use Psr\Http\Client\ClientInterface; $response = $client->sendRequest($request);

@dbrumann / [email protected] 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 / [email protected] 31 NetworkExceptionInterface

@dbrumann / [email protected] 32 A Client must not treat a well-formed HTTP request or HTTP response as an error condition.

@dbrumann / [email protected] 33 Wie konfiguriere ich meinen HttpClient?

@dbrumann / [email protected] 34 Wie kann ich Requests asynchron versenden?

@dbrumann / [email protected] 35 Was ist mit HTTP/2- oder HTTP/3-Features?
