Drupal::request()->request->all() returns an empty array

Question

I have a custom controller that expects POST data. I had it working fine in 8.1.0 retrieving the data using \Drupal::request()->request->all() and \Drupal::request()->request->get($myvar).

Now, without any changes in my custom module, \Drupal::request()->request->all() is returning an empty array, and \Drupal::request()->request->get($myvar) is returning NULL.

Between the time it was working and when the issue arose, my hosting service Pantheon updated their Drupal 8 version from 8.1.0 to 8.1.1 and then 8.1.2. I suspect something may have changed then that affected this.

How can I fix this?

EDIT: Thanks for the comments, still not quite working...

Route YAML:

mymodule.foobar:
  path: '/foobar'
  options:
    _auth: [ 'basic_auth' ]
  defaults:
    _controller: '\Drupal\mymodule\Controller\FooBarController::foobar'
    _title: 'foobar'
  requirements:
    _user_is_logged_in: 'TRUE'
    _permission: 'administer site configuration'

Controller:

<?php
namespace Drupal\mymodule\Controller;
use Drupal\Core\Controller\ControllerBase;
use Symfony\Component\HttpFoundation\JsonResponse;
use Symfony\Component\HttpFoundation\Request;
/**
 * Class FooBarController.
 *
 * @package Drupal\mymodule\Controller
 */
class FooBarController extends ControllerBase {
  /**
   * Provides content for the /mymodule/foobar path.
   *
   * @param \Symfony\Component\HttpFoundation\Request $request
   *   The current request
   */
  public function foobar(Request $request) {
    $content = $request->getContent();
    $data = array();
    $data['a'] = $request->get('foo');
    $data['b'] = $request->request->get('foo');
    $data['c'] = \Drupal::requestStack()->getCurrentRequest()->request->get('foo');
    $data['e'] = $request->request->all();
    $data['f'] = $content;

    $request = \Drupal::requestStack()->getCurrentRequest();
    $content = $request->getContent();
    $data['g'] = $request->get('foo');
    $data['h'] = $request->request->get('foo');
    $data['j'] = $request->request->all();
    $data['k'] = $content;

    return new JsonResponse((object) $data);
  }
}

Postman Request:

Note: This was working before with this exact code, correctly using basic HTTP authentication. There have been no changes other than these variations to my controller, and core updates.

Any more ideas?

Answer 1

I had the same issue and the request parameters were always empty. I think it could be due to using it in a controller rather than a REST endpoint but I'm not sure.

The following line of code worked for me:

$request->getContent();

Answer 2

Try this:

$request = \Drupal::requestStack()->getCurrentRequest()->query->all();

Sidenote: Using a Controller you shouldn't use "\Drupal::..." static request call. Instead, you always have in your controller's enter point function a "Request $request" object as a last argument.
