RequestObjectResolverBundle

This bundle can help you to deserialize incoming request parameters from symfomy http request object to your DTO objects.

Deserialized objects are validated via symfony/validator, so when using such objects in controllers, we can be sure that the data format and their set in the object are correct and ready for further processing.

Bundle can deserialize:

• route parameters (attribute RequestObjectResolverBundle\Attribute\Path)
• query parameters (attribute RequestObjectResolverBundle\Attribute\Query)
• content body (supports all symfony serializer formats) (attribute RequestObjectResolverBundle\Attribute\Content)
• form parameters (attribute RequestObjectResolverBundle\Attribute\Form)
• uploaded files (attribute RequestObjectResolverBundle\Attribute\Form)

Install

composer require mops1k/request-object-resolver-bundle

Use

Example:

<?php

use RequestObjectResolverBundle\Attribute\Query;
use RequestObjectResolverBundle\Attribute\Path;
use Symfony\Bundle\FrameworkBundle\Controller\AbstractController;
use Symfony\Component\HttpFoundation\JsonResponse;
use Symfony\Component\HttpFoundation\Request;
use Symfony\Component\Routing\Annotation\Route;
use Symfony\Component\Validator\Constraints as Assert;

class ExampleRequest
{
    #[Assert\NotNull]
    #[Assert\GreaterThan(0)]
    public ?int $id = null;
    
    #[Assert\NotNull]
    #[Assert\NotBlank]
    public ?string $name = null;
}

/**
 * Request path example: /25?name=Julian
 */
class ExampleController extends AbstractController
{
    #[Route('/{id}', methods: [Request::METHOD_GET])]
    public function __invoke(#[Query, Path] ExampleRequest $exampleRequest): JsonResponse
    {
        // some logic with $exampleRequest
        
        return new JsonResponse([
            'id' => $exampleRequest->id,
            'name' => $exampleRequest->name,
        ]);
    }
}

Map field to another name

Whole library attributes have a map parameter. With this parameter you can map from one field name to another.

Example:

<?php

use RequestObjectResolverBundle\Attribute\Query;
use RequestObjectResolverBundle\Attribute\Path;
use Symfony\Bundle\FrameworkBundle\Controller\AbstractController;
use Symfony\Component\HttpFoundation\JsonResponse;
use Symfony\Component\HttpFoundation\Request;
use Symfony\Component\Routing\Annotation\Route;
use Symfony\Component\Validator\Constraints as Assert;

class ExampleRequest
{
    #[Assert\NotNull]
    #[Assert\GreaterThan(0)]
    public ?int $id = null;
    
    #[Assert\NotNull]
    #[Assert\NotBlank]
    public ?string $title = null;
}

/**
 * Request path example: /25?name=Julian
 */
class ExampleController extends AbstractController
{
    #[Route('/{id}', methods: [Request::METHOD_GET])]
    public function __invoke(#[Query(map: ['name' => 'title']), Path] ExampleRequest $exampleRequest): JsonResponse
    {
        // some logic with $exampleRequest
        
        return new JsonResponse([
            'id' => $exampleRequest->id,
            'title' => $exampleRequest->name,
        ]);
    }
}

Skip dto validation

If your logic does not need automatic validation of the request object for some reason, then you can disable it with RequestObjectResolverBundle\Attribute\SkipValidation attribute.

Example:

<?php

use RequestObjectResolverBundle\Attribute\Query;
use RequestObjectResolverBundle\Attribute\Path;
use RequestObjectResolverBundle\Attribute\SkipValidation;
use Symfony\Bundle\FrameworkBundle\Controller\AbstractController;
use Symfony\Component\HttpFoundation\JsonResponse;
use Symfony\Component\HttpFoundation\Request;
use Symfony\Component\Routing\Annotation\Route;
use Symfony\Component\Validator\Constraints as Assert;

class ExampleRequest
{
    #[Assert\NotNull]
    #[Assert\GreaterThan(0)]
    public ?int $id = null;
    
    #[Assert\NotNull]
    #[Assert\NotBlank]
    public ?string $name = null;
}

/**
 * Request path example: /-1?name=
 */
class ExampleController extends AbstractController
{
    #[Route('/{id}', methods: [Request::METHOD_GET])]
    public function __invoke(#[Query, Path, SkipValidation] ExampleRequest $exampleRequest): JsonResponse
    {
        // some logic with $exampleRequest
        
        return new JsonResponse([
            'id' => $exampleRequest->id,
            'name' => $exampleRequest->name,
        ]);
    }
}

Validation groups

If you want to use validation groups, then use attribute \RequestObjectResolverBundle\Attribute\ValidationGroups.

Example:

<?php

use RequestObjectResolverBundle\Attribute\Query;
use RequestObjectResolverBundle\Attribute\Path;
use RequestObjectResolverBundle\Attribute\ValidationGroups;
use Symfony\Bundle\FrameworkBundle\Controller\AbstractController;
use Symfony\Component\HttpFoundation\JsonResponse;
use Symfony\Component\HttpFoundation\Request;
use Symfony\Component\Routing\Annotation\Route;
use Symfony\Component\Validator\Constraints as Assert;

class ExampleRequest
{
    #[Assert\NotNull]
    #[Assert\GreaterThan(0, groups: ['default'])]
    public ?int $id = null;
    
    #[Assert\NotNull]
    #[Assert\NotBlank]
    public ?string $name = null;
}

/**
 * Request path example: /25?name=Julian
 */
class ExampleController extends AbstractController
{
    #[Route('/{id}', methods: [Request::METHOD_POST])]
    public function __invoke(#[Query, Path, ValidationGroups(groups: 'default')] ExampleRequest $exampleRequest): JsonResponse
    {
        // some logic with $exampleRequest
        
        return new JsonResponse([
            'id' => $exampleRequest->id,
            'name' => $exampleRequest->name,
        ]);
    }
}

Serialization context

If you want to add some serialization context, then in attributes you can set serializationContext property.

Example:

<?php

use RequestObjectResolverBundle\Attribute\Query;
use RequestObjectResolverBundle\Attribute\Path;
use RequestObjectResolverBundle\Attribute\ValidationGroups;
use Symfony\Bundle\FrameworkBundle\Controller\AbstractController;
use Symfony\Component\HttpFoundation\JsonResponse;
use Symfony\Component\HttpFoundation\Request;
use Symfony\Component\Routing\Annotation\Route;
use Symfony\Component\Serializer\Annotation\Groups;
use Symfony\Component\Validator\Constraints as Assert;

class ExampleRequest
{
    #[Assert\NotNull]
    #[Assert\GreaterThan(0)]
    #[Groups(['default'])]
    public ?int $id = null;
    
    #[Assert\NotNull]
    #[Assert\NotBlank]
    public ?string $name = null;
}

/**
 * Request path example: /25?name=Julian
 */
class ExampleController extends AbstractController
{
    #[Route('/{id}', methods: [Request::METHOD_POST])]
    public function __invoke(#[Query(serializerContext: ['groups': ['default']]), Path] ExampleRequest $exampleRequest): JsonResponse
    {
        // some logic with $exampleRequest
        
        return new JsonResponse([
            'id' => $exampleRequest->id,
            'name' => $exampleRequest->name, // will throw error as uninitialized property
        ]);
    }
}

If you want to set context to all request parts which you want to deserialize to object, use \RequestObjectResolverBundle\Attribute\SerializerContext attribute.

<?php

use RequestObjectResolverBundle\Attribute\Query;
use RequestObjectResolverBundle\Attribute\Path;
use RequestObjectResolverBundle\Attribute\SerializerContext;
use Symfony\Bundle\FrameworkBundle\Controller\AbstractController;
use Symfony\Component\HttpFoundation\JsonResponse;
use Symfony\Component\HttpFoundation\Request;
use Symfony\Component\Routing\Annotation\Route;
use Symfony\Component\Serializer\Annotation\Groups;
use Symfony\Component\Validator\Constraints as Assert;

class ExampleRequest
{
    #[Assert\NotNull]
    #[Assert\GreaterThan(0)]
    #[Groups(['default'])]
    public ?int $id = null;
    
    #[Assert\NotNull]
    #[Assert\NotBlank]
    public ?string $name = null;
}

/**
 * Request path example: /25?name=Julian
 */
class ExampleController extends AbstractController
{
    #[Route('/{id}', methods: [Request::METHOD_POST])]
    public function __invoke(#[Query, Path, SerializerContext(['groups': ['default']])] ExampleRequest $exampleRequest): JsonResponse
    {
        // some logic with $exampleRequest
        
        return new JsonResponse([
            'id' => $exampleRequest->id,
            'name' => $exampleRequest->name, // will throw error as uninitialized property
        ]);
    }
}

Overriding values with request parts combination

These are table of request parts priority overriding (if have same key name):

Request part	Priority (lower value = higher priority)
Query	30
Path	20
Form	10
Content	0

Example. If you handle Path, Query and Content in same object and all of them have same field (id for example), then resulting field value will be from Form request part.
