Yii Data Response

The package allows responding with data that is automatically converted into PSR-7 response.

Requirements

• PHP 8.1 - 8.5.
• DOM PHP extension.

Installation

The package could be installed with Composer:

composer require yiisoft/data-response

General usage

The package provides DataResponseFactory class that, given a PSR-17 response factory, is able to create data response.

Data response contains raw data to be processed later.

use Yiisoft\DataResponse\DataResponseFactory;

/**
 * @var Psr\Http\Message\ResponseFactoryInterface $responseFactory
 */

$factory = new DataResponseFactory($responseFactory);
$dataResponse = $factory->createResponse('test');
$dataResponse
    ->getBody()
    ->rewind();

echo $dataResponse
    ->getBody()
    ->getContents(); // "test"

Formatters

Formatter purpose is to format a data response. In the following example we format data as JSON.

use Yiisoft\DataResponse\DataResponseFactory;
use Yiisoft\DataResponse\Formatter\JsonDataResponseFormatter;

/**
 * @var Psr\Http\Message\ResponseFactoryInterface $responseFactory
 */

$factory = new DataResponseFactory($responseFactory);
$dataResponse = $factory->createResponse('test');
$dataResponse = $dataResponse->withResponseFormatter(new JsonDataResponseFormatter());
$dataResponse
    ->getBody()
    ->rewind();

echo $dataResponse->getHeader('Content-Type'); // ["application/json; charset=UTF-8"]
echo $dataResponse
    ->getBody()
    ->getContents(); // "test"

The following formatters are available:

• HtmlDataResponseFormatter
• JsonDataResponseFormatter
• XmlDataResponseFormatter
• PlainTextDataResponseFormatter

Middleware

The package provides a PSR-15 middleware that is able to format a data response.

use Yiisoft\DataResponse\Middleware\FormatDataResponse;
use Yiisoft\DataResponse\Formatter\JsonDataResponseFormatter;

$middleware = (new FormatDataResponse(new JsonDataResponseFormatter()));
//$middleware->process($request, $handler);

Also, the package provides PSR-15 middleware for content negotiation:

use Yiisoft\DataResponse\Formatter\HtmlDataResponseFormatter;
use Yiisoft\DataResponse\Formatter\XmlDataResponseFormatter;
use Yiisoft\DataResponse\Formatter\JsonDataResponseFormatter;
use Yiisoft\DataResponse\Middleware\ContentNegotiator;

$middleware = new ContentNegotiator([
    'text/html' => new HtmlDataResponseFormatter(),
    'application/xml' => new XmlDataResponseFormatter(),
    'application/json' => new JsonDataResponseFormatter(),
]);

You can override middlewares with method withContentFormatters():

$middleware->withContentFormatters([
    'application/xml' => new XmlDataResponseFormatter(),
    'application/json' => new JsonDataResponseFormatter(),
]);
