Yii Request Model

Request model simplifies working with request data. It allows you to decorate data for easy retrieval and automatically validate it when needed.

Installation

The package could be installed with composer:

composer require yiisoft/request-model

According to yiisoft/middleware-dispatcher docs, you need to set the implementation of ParametersResolverInterface to HandlerParametersResolver via container or pass directly.

General usage

A simple version of the request model looks like the following:

use Yiisoft\RequestModel\RequestModel;
use Yiisoft\Validator\RulesProviderInterface;
use Yiisoft\Validator\Rule\Email;
use Yiisoft\Validator\Rule\Required;

final class AuthRequest extends RequestModel implements RulesProviderInterface
{
    public function getLogin(): string
    {
        return (string)$this->getAttributeValue('body.login');
    }

    public function getPassword(): string
    {
        return (string)$this->getAttributeValue('body.password');
    }

    public function getRules(): array
    {
        return [
            'body.login' => [
                new Required(),
                new Email(),
            ],
            'body.password' => [
                new Required(),
            ]
        ];
    }
}

Route:

 Route::post('/test')
    ->action([SimpleController::class, 'action'])
    ->name('site/test')

Usage in controller:

use Psr\Http\Message\ResponseInterface;

final class SimpleController
{
    public function action(AuthRequest $request): ResponseInterface
    {
        echo $request->getLogin();
        ...
    }
}

If the data does not pass validation, RequestValidationException will be thrown. If you need to handle an exception and, for example, send a response, you can intercept its middleware.

For example:

final class ExceptionMiddleware implements MiddlewareInterface
{
    public function process(ServerRequestInterface $request, RequestHandlerInterface $handler): ResponseInterface
    {
        try {
            return $handler->handle($request);
        } catch (RequestValidationException $e) {
            return new Response(400, [], $e->getFirstError());
        }
    }
}

You can use the request model without validation. To do this, you need to remove the ValidatableModelInterface. In this case, the data will be included into the model, but will not be validated. For example:

final class ViewPostRequest extends RequestModel
{
    public function getId(): int
    {
        return (int)$this->getAttributeValue('router.id');
    }
}

Inside the request model class, data is available using the following keys:

key	source
query	$request->getQueryParams()
body	$request->getParsedBody()
attributes	$request->getAttributes()
headers	$request->getHeaders()
files	$request->getUploadedFiles()
cookie	$request->getCookieParams()
router	$currentRoute->getArguments()

This data can be obtained as follows

$this->requestData['router']['id'];

or through the methods

$this->hasAttribute('body.user_id');
$this->getAttributeValue('body.user_id');

Attributes

You can use attributes in an action handler to get data from a request:

use Psr\Http\Message\ResponseInterface;
use Yiisoft\RequestModel\Attribute\Request;
use Yiisoft\RequestModel\Attribute\Route;

final class SimpleController
{
    public function action(#[Route('id')] int $id, #[Request('foo')] $attribute,): ResponseInterface
    {
        echo $id;
        //...
    }
}
