yiisoft/input-http

View on github

The package provides Yii Hydrator attributes to get data from PSR-7 HTTP request and adds extra abilities to middlewares processed by Yii Middleware Dispatcher:

maps data from PSR-7 HTTP request to PHP DTO representing user input;
uses Yii Hydrator parameter attributes for resolving middleware parameters.

Requirements

PHP 8.1 or higher.

Installation

The package could be installed with Composer:

composer require yiisoft/input-http

General usage

Yii Input HTTP allows to have DTO with attributes like this:

use Yiisoft\Input\Http\AbstractInput;
use Yiisoft\Input\Http\Attribute\Data\FromBody;

#[FromBody]
final class UpdatePostInput extends AbstractInput
{
    public int $id;
    public string $title;
    public string $description = '';
    public string $content;
}

and automatically resolve and hydrate it, for example, for arguments like that:

final class UpdatePostController
{
    public function update(UpdatePostInput $post): ResponseInterface
    {
        // ...
        
        /** @var ResponseInterface $response */
        return $response;
    }
}

Basic steps:

Configure storing request.
Configure parameters resolver.
Create DTO (request input).
Mark DTO properties with hydrator attributes provided by this package.
Add DTO class name as type hint to a class method argument where you want to it to be resolved.
