PSR-7
You can get server side request information using PSR7 HTTP message interface. Also, you can run BEAR.Sunday application as PSR 7 middleware.
HTTP Request
PHP has Superglobals such as $_SERVER and $_COOKIE, but instead of using them it receives server side request information using the PSR-7 HTTP message interface.
ServerRequest （general）
class Index extends ResourceObject
{
public function __construct(ServerRequestInterface $serverRequest)
{
// retrieve cookies
$cookie = $serverRequest->getCookieParams(); // $_COOKIE
}
}
Upload Files
use Psr\Http\Message\UploadedFileInterface;
use Ray\HttpMessage\Annotation\UploadFiles;
class Index extends ResourceObject
{
/**
* @UploadFiles
*/
public function __construct(array $files)
{
// retrieve file name
$file = $files['my-form']['details']['avatar'][0]
/* @var UploadedFileInterface $file */
$name = $file->getClientFilename(); // my-avatar3.png
}
}
URI
use Psr\Http\Message\UriInterface;
class Index extends ResourceObject
{
public function __construct(UriInterface $uri)
{
// retrieve host name
$host = $uri->getHost();
}
}
PSR-7
An existing BEAR.Sunday application can work as a PSR-7 middleware with these easy steps:
1) Add bear/middleware package then replace bootstrap.php script.
composer require bear/middleware
cp vendor/bear/middleware/bootstrap/bootstrap.php bootstrap/bootstrap.php
2) Replace __PACKAGE__\__VENDOR__ in bootstrap.php to application namespace.
Stat the server.
php -S 127.0.0.1:8080 -t public
Stream
BEAR.Sunday supports HTTP body of a message output in a stream.
In ResourceObject, you can mix stream with a normal string. The output is converted to a single stream.
StreamTransfer is the default HTTP transfer. Seem more at Stream Response.
New Project
You can also create a BEAR.Sunday PSR-7 project with bear/project from scratch.
composer create-project bear/project my-psr7-project
cd my-psr7-project/
php -S 127.0.0.1:8080 -t public
