Symfony2 serialze entity escape backslash from output

Question

Hi I am using Symfony2 for my application. I am using the serializer component.

    $encoder = new JsonEncoder();
    $normalizer = new GetSetMethodNormalizer();

    $callback = function ($dateTime) {
        return $dateTime instanceof \DateTime
            ? $dateTime->format(\DateTime::ISO8601)
            : '';
    };

    $normalizer->setCallbacks(array('matchAStartTime' => $callback, 'matchBStartTime'=> $callback, 'matchDate'=> $callback));
    $normalizer->setIgnoredAttributes(array('createdAt', 'updatedAt'));
    $serializer = new Serializer(array($normalizer), array($encoder));
    $json = $serializer->serialize($entity, 'json');

but in the output i am having response like this:

\"id\":1,\"matchAStatus\":\"Live\"

my question is how can I remove that slash in output? I know in raw php there is option for escape backslash but what can I use in Symfony?

How do you output your JSON? Do you use twig or simple echo? — Irmantas

I had the same problem and it not come from Serializer but the way I return the response:

Do this (Take note of the true):

return new JsonResponse($serialized, 200, array(), true);

Instead of:

return new JsonResponse($serialized);

in order to avoid JsonResponse to encode an encoded JSON and thus quoted the JSON.

I've been struggling with this problem as well. Yey I've used another approach maybe it would be good for you to know.

Symfony 2 serializer allow you to specify some options that will be used by the JsonEncoder directly passed to json_encode function. Then you can personalize your usage adding more options under the key json_encode_options of the third parameter array passed to the serialize method

$serializer->serialize($entity, 'json',  ['json_encode_options' => JSON_UNESCAPED_SLASHES]);

You can use JSON_UNESCAPED_SLASHES constant (php >= 5.4.0).

use Symfony\Component\Serializer\Encoder\JsonDecode;
use Symfony\Component\Serializer\Encoder\JsonEncode;

$encoder = new JsonEncoder(new JsonEncode(JSON_UNESCAPED_SLASHES), new JsonDecode(false))
