README
This package provides JsonApiError
and JsonApiErrorResponse
classses to conveniently handle errors following the JSON:API specification.
The JsonApiErrorResponse
extends the JsonResponse
from symfony/http-foundation
, so this package is meant to be used in projects using that.
Table of contents:
Install
Install this package via composer:
composer require wunderwerkio/jsonapi-error
Usage
Return a simple error response
<?php use Symfony\Component\HttpFoundation\Response; use Wunderwerk\JsonApiError\JsonApiErrorResponse; function someRequestHandler(): Response { return JsonApiErrorResponse::fromArray([ 'code' => 'application_error_code', 'title' => 'An error occured!', 'status' => 500, ]); }
The above code would result in a JSON response with the following payload:
{ "errors": [{ "status": 500, "code": "application_error_code", "title": "An error occured!" }] }
Return multiple errors
<?php use Symfony\Component\HttpFoundation\Response; use Wunderwerk\JsonApiError\JsonApiErrorResponse; function someRequestHandler(): Response { return JsonApiErrorResponse::fromArrayMultiple([ [ 'status' => 422, 'code' => 'validation_failed', 'title' => 'Invalid request payload', 'detail' => 'The "name" field is required.', 'source' => [ 'pointer' => '/data/name' ] ], [ 'status' => 422, 'code' => 'validation_failed', 'title' => 'Invalid request payload', 'detail' => 'The "description" field is required.', 'source' => [ 'pointer' => '/data/description' ] ], ]); }
The above code would result in a JSON response with the following payload:
{ "errors": [{ "status": 422, "code": "validation_failed", "title": "Invalid request payload", "detail": "The \"name\" field is required.", "source": { "pointer": "/data/name" } }, { "status": 422, "code": "validation_failed", "title": "Invalid request payload", "detail": "The \"description\" field is required.", "source": { "pointer": "/data/description" } }] }
Build response from JsonApiError
objects
To ease building a response with multiple errors, the response can also be created by constricting it by
passing an array of JsonApiError
objects.
<?php use Symfony\Component\HttpFoundation\Request; use Symfony\Component\HttpFoundation\JsonResponse; use Symfony\Component\HttpFoundation\Response; use Wunderwerk\JsonApiError\JsonApiError; use Wunderwerk\JsonApiError\JsonApiErrorResponse; function someRequestHandler(Request $request): Response { /** @var JsonApiError[] $errors */ $errors = []; $payload = $request->getContent(); $entity = json_decode($payload, TRUE); // Make sure 'name' field is set. if (!array_key_exists('name', $entity['data'])) { $errors[] = JsonApiError::fromArray([ 'status' => 422, 'code' => 'validation_failed', 'title' => 'Invalid request payload', 'detail' => 'The "name" field is required.', 'source' => [ 'pointer' => '/data/name', ], ]); } // Make sure 'description' field is set. if (!array_key_exists('description', $entity['data'])) { $errors[] = JsonApiError::fromArray([ 'status' => 422, 'code' => 'validation_failed', 'title' => 'Invalid request payload', 'detail' => 'The "description" field is required.', 'source' => [ 'pointer' => '/data/description', ], ]); } if (!empty($errors)) { return new JsonApiErrorResponse($errors); } return new JsonResponse([ 'status' => 'success', ]); }
