Converting to PSR-7
This module works by providing either a HTTPRequest
or a HTTPResponse
class that is pre-configured and ready to be sent to the client/server to the corresponding adapter class:
HTTPRequest
uses theRobbie\Psr7\HttpRequestAdapter
classHTTPResponse
uses theRobbie\Psr7\HttpResponseAdapter
class
To retrieve a bootstrapped PSR-7 ServerRequestInterface
or ResponseInterface
you can call ->toPsr7($request)
on either of these classes, for example:
<?php $myResponse = new \SilverStripe\Control\HTTPResponse( json_encode(['success' => true, 'message' => 'Your request was successful!']), 200, 'OK' ); /** @var \Psr\Http\Message\ResponseInterface $response */ $response = (new \Robbie\Psr7\HttpResponseAdapter)->toPsr7($myResponse);
From here you can use any of the PSR-7 interface methods, and the results will be immutable:
<?php $newResponse = $response->withHeader('Content-Type', 'application/json'); $newResponse = $newResponse->withHeader('X-Custom-Header', 'my-value-here'); // $response !== $newResponse -> #psr7-ftw
The same concept applies to the HttpRequestAdapter
, for example:
<?php # Context: PageController use Robbie\Psr7\HttpRequestAdapter; // ... $request = $this->getRequest(); $adapter = new HttpRequestAdapter; $psrInterface = $adapter->toPsr7($request); // Outputs all your initial request headers: print_r($psrInterface->getHeaders());
Converting from PSR-7
To return a PSR-7 interface back to either an HTTPRequest
or HTTPResponse
class you simply need to do the same thing as going to, only use ->fromPsr7($input)
instead:
<?php // $requestInterface is an instance of Psr\Http\Message\ServerRequestInterface $httpRequest = (new HttpRequestAdapter)->fromPsr7($requestInterface);
$httpRequest
is now a SilverStripe\Control\HTTPRequest
instance.
