…and `#[MapQueryString]` to map Request input to typed objects (Koc)This PR was merged into the 6.3 branch.Discussion----------[HttpKernel] Create Attributes `#[MapRequestPayload]` and `#[MapQueryString]` to map Request input to typed objects| Q             | A| ------------- | ---| Branch?       | 6.3| Bug fix?      | no| New feature?  | yes| Deprecations? | no| Tickets       |#36037,#36093,#45628,#47425,#49002,#49134| License       | MIT| Doc PR        | TBDYet another variation of how we can map raw Request data to typed objects with validation. We can even build OpenApi Specification based on this DTO classes using [NelmioApiDocBundle](https://github.com/nelmio/NelmioApiDocBundle).## Usage Example 🔧### `#[MapRequestPayload]````phpclass PostProductReviewPayload{    public function __construct(        #[Assert\NotBlank]        #[Assert\Length(min: 10, max: 500)]        public readonly string $comment,        #[Assert\GreaterThanOrEqual(1)]        #[Assert\LessThanOrEqual(5)]        public readonly int $rating,    ) {    }}class PostJsonApiController{    public function __invoke(        #[MapRequestPayload] PostProductReviewPayload $payload,    ): Response {        // $payload is validated and fully typed representation of the request body $request->getContent()        //  or $request->request->all()    }}```### `#[MapQueryString]````phpclass GetOrdersQuery{    public function __construct(        #[Assert\Valid]        public readonly ?GetOrdersFilter $filter,        #[Assert\LessThanOrEqual(500)]        public readonly int $limit = 25,        #[Assert\LessThanOrEqual(10_000)]        public readonly int $offset = 0,    ) {    }}class GetOrdersFilter{    public function __construct(        #[Assert\Choice(['placed', 'shipped', 'delivered'])]        public readonly ?string $status,        public readonly ?float $total,    ) {    }}class GetApiController{    public function __invoke(        #[MapQueryString] GetOrdersQuery $query,    ): Response {        // $query is validated and fully typed representation of the query string $request->query->all()    }}```### Exception handling 💥- Validation errors will result in an HTTP 422 response, accompanied by a serialized `ConstraintViolationList`.- Malformed data will be responded to with an HTTP 400 error.- Unsupported deserialization formats will be responded to with an HTTP 415 error.## Comparison to another implementations 📑Differences to#49002:- separate Attributes for explicit definition of the used source- no need to define which class use to map because Attributes already associated with typed argument- used ArgumentValueResolver mechanism instead of Subscribers- functional testsDifferences to#49134:- it is possible to map whole query string to object, not per parameter- there is validation of the mapped object- supports both `$request->getContent()` and `$request->request->all()` mapping- functional testsDifferences to#45628:- separate Attributes for explicit definition of the used source- supports `$request->request->all()` and `$request->query->all()` mapping- Exception handling opt-in- functional tests## Bonus part 🎁- Extracted `UnsupportedFormatException` which thrown when there is no decoder for a given formatCommits-------d987093 [HttpKernel] Create Attributes `#[MapRequestPayload]` and `#[MapQueryString]` to map Request input to typed objects

…or custom http status code (zim32)This PR was merged into the 6.4 branch.Discussion----------[HttpKernel] RequestPayloadValueResolver Add support for custom http status code| Q             | A| ------------- | ---| Branch?       | 6.4| Bug fix?      | no| New feature?  | yes| Deprecations? | no| Tickets       | no| License       | MIT| Doc PR        | Will do if acceptedReading this discussion#49134 (comment) it looks like a good idea to have ability to customize http status code in case of a validation error.This MR does not create any BC's.**MapQueryString** and **MapRequestPayload** attributes now have additional parameter `validationFailedStatusCode`, which allows to specify which http status code will be used if validation fails.Commits-------4d118c0 [HttpKernel] RequestPayloadValueResolver Add support for custom http status code
