Usage
Create validation schemes
See json-schema for more details
JsonSchema/Request/myAction.json
{ "description": "Request JSON schema", "type": "object", "properties": { "test": { "type": "string", "minLength": 1 } }, "required": [ "test" ] }
JsonSchema/Response/myAction.json
{ "description": "Response JSON schema", "type": "object", "properties": { "test": { "type": "string", "minLength": 1 } }, "required": [ "test" ] }
Create controller with annotations ValidateJsonRequest
and/or ValidateJsonResponse
Specify $validJson
argument if you want get decoded JSON data from the request
Specify the array
type of the $validJson
argument if you want get decoded JSON data as array
Specify the object
type of the $validJson
argument or don't specify type if you want get decoded JSON data as object
Controller/MyController.php
<?php use Mrsuh\JsonValidationBundle\Annotation\ValidateJsonRequest; use Mrsuh\JsonValidationBundle\Annotation\ValidateJsonResponse; use Symfony\Component\HttpFoundation\JsonResponse; class MyController { /** * @ValidateJsonRequest("JsonSchema/Request/myAction.json", methods={"POST"}, emptyIsValid=true) * @ValidateJsonResponse("JsonSchema/Response/myAction.json", statuses={"200"}, emptyIsValid=true) */ public function myAction(array $validJson): JsonResponse { return new JsonResponse($validJson); } }
Invalid JSON passed to request
If invalid JSON passed to request and config enable_request_listener
, enable_exception_listener
enabled
you get response as detailed in RFC7807 with header Content-Type:application/problem+json
and error
log entry
{ "detail": "There was a problem with the JSON that was sent with the request", "errors": [ { "constraint": "minLength", "context": 1, "message": "Must be at least 1 characters long", "minLength": 1, "pointer": "/test", "property": "test" } ], "status": 400, "title": "Unable to parse/validate JSON" }
app.ERROR: Json request validation {"uri":"http://127.0.0.1:8000/my","schemaPath":"JsonSchema/Request/myAction.json","errors":[{"property":"test","pointer":"/test","message":"Must be at least 1 characters long","constraint":"minLength","context":1,"minLength":1}]} []
Invalid JSON passed to response
If invalid JSON passed to response and config enable_response_listener
enabled
you get warning
log entry
app.WARNING: Json response validation {"uri":"http://127.0.0.1:8000/my","schemaPath":"JsonSchema/Response/myAction.json","errors":[{"property":"test","pointer":"/test","message":"Must be at least 1 characters long","constraint":"minLength","context":1,"minLength":1}]} []

Single validator usage
<?php use Mrsuh\JsonValidationBundle\JsonValidator\JsonValidator; use Symfony\Component\HttpFoundation\Request; use Symfony\Component\HttpFoundation\Response; class MyController { public function myAction(Request $request, JsonValidator $validator): Response { $validator->validate($request->getContent(), 'JsonSchema/Request/myAction.json'); $errors = $validator->getErrors(); if(!empty($errors)) { // do something with errors } return new Response(); } }
