This is an annotation-based validation extension for the php-json-rpc library. It validates the JSON-RPC API endpoints against well-defined constraints, e.g. type checking, regex checking, etc.
The library depends on symfony/Validator, doctrine/annotations as well as on php-json-rpc-simple.
Annotate your API endpoint classes like this:
namespace Datto\API;
use Datto\JsonRpc\Validator\Validate;
use Symfony\Component\Validator\Constraints as Assert;
class Math
{
/**
* @Validate(fields={
* "a" = @Assert\Type(type="integer"),
* "b" = {
* @Assert\Type(type="integer"),
* @Assert\NotEqualTo(value="0"),
* }
* })
*/
public function divide($a, $b)
{
return $a / $b;
}Once you have that, just use it like this. This example uses the Simple\Evaluator (see php-json-rpc-simple) as underlying mapping mechanism:
$server = new Server(new Validator\Evaluator(new Simple\Evaluator()));
$result = $server->reply('{"jsonrpc": "2.0", "method": "math/divide", "params": { "a": 1, "b": 0 }, "id": 1}');
// Because 'b' cannot be 0, this will return
// {"jsonrpc":"2.0","id":1,"error":{"code":-32602,"message":"Invalid params"}}- PHP >= 5.3
