README

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.

Examples

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"}}
