Disable symfony 2 csrf token protection on ajax su

问题:

i'm building a mobile app talking to my symfony2 app via webservices I can't find a way to disable csrf protection on a specific controller/action

i want to post registration data to this action and use sf2 form validation. I do not call the form in my mobile app

Can't change container parameters in action, throw an exception because it is a frozen parameter...

I do not want to disable form protection for whole my application

any clue ?

thanks !

update: with symfony 2.1.x

/**
 * {@inheritdoc}
 */
public function setDefaultOptions(OptionsResolverInterface $resolver)
{
    $resolver->setDefaults(array(
        'csrf_protection'   => false,
    ));
}

If you're looking for a bit easier and faster solution than suggested in answer above, here's how:

<?php

// ...

use Symfony\Component\Form\AbstractType;
use Symfony\Component\Form\FormBuilder;
use Symfony\Component\OptionsResolver\OptionsResolver;

class MyType extends AbstractType
{
    // ...

   public function configureOptions(OptionsResolver $resolver)
    {
        $resolver->setDefaults(array(
            'csrf_protection' => false,
        ));
    }
}

.. or if you're using older versions (Symfony 2.0.*):

<?php

// ...

use Symfony\Component\Form\AbstractType;
use Symfony\Component\Form\FormBuilder;

class MyType extends AbstractType
{
    // ....

    public function getDefaultOptions(array $options)
    {
        $options = parent::getDefaultOptions($options);
        $options['csrf_protection'] = false;

        return $options;
    }
}

Consult the Symfony documentation for additional information.

Using the form factory

For those who want to create a simple form in a controller:

$form = $this->container->get('form.factory')
    ->createNamedBuilder(null, 'form', null, array('csrf_protection' => false))
    ->add('yourField','text', array(
        'label' => false,
        'mapped' => false
    ))
    ->getForm();

回答3:

public function configureOptions(OptionsResolver $resolver)
{
    $resolver->setDefaults([
        'csrf_protection' => false,
    ]);
}

Using the form factory in Symfony 3

use Symfony\Component\Form\Extension\Core\Type\FormType;

$form = $this->container->get('form.factory')
    ->createNamedBuilder(null, FormType::class, null, array('csrf_protection' => false))
    ->add('yourField','text', array(
        'label' => false,
        'mapped' => false
    ))
    ->getForm();

I can't be 100% sure but I think I read somewhere that you can pass csrf_provider option while creating form.

All providers are subtypes of interface Symfony\Component\Form\Extension\Csrf\CsrfProvider and you should be able to create your own:

class MyNonCsrfProvider extends DefaultCsrfProvider{
    public function isCsrfTokenValid($intention, $token)
    {
        return true;
    }
}

and in controller:

$this->createForm(new CustomFormType(), array(
    'csrf_provider' => new MyNonCsrfProvider()
));

I haven't tried this myself but this sounds like a possible solution...
