POST variables not seen in Symfony's 3.2 Controller

Question

Debugger shows, that there is POST data in request, but I cannot get it by $request->get('foo');

And $request->request->all(); gives array [0].

My Ajax POST request (by AngularJS):

...
    $http.post('http://admin/about-company/setJSONObj',
        {foo: 'bar'}
    );

My controller with debugging info in comments (Symfony 3.2.9):

use Symfony\Component\HttpFoundation\Request;
    ...
    public function updateAction(Request $request)
        {
             $foo = $request->get('foo'); // null
             $requestType = $request->getContentType(); // json
             $content = $request->getContent(); // {"foo":"bar"}

I used these approach on Symfony 2.7 project, and it worked fine, but I'm not sure, what's happening in these case?

Also, maybe there is any Symfony framework config variable that tells not to parse POST data, or hides it during caching the request?

I don't know about pre 2.8 (started late) but see [symfony-request-object](http://symfony.com/doc/current/introduction/http_fundamentals.html#symfony-request-object) — Jenne, Jun 02 '17 at 12:13
Thanks guys, seems I tried all such variants and not worked. I think soon I'll parce json from $content to roughly fix this ))) — Parks, Jun 02 '17 at 12:19
@eRIZ, nope, I think AngularJS cares about headers. By the way it sends Content-Type:application/json;charset=UTF-8 — Parks, Jun 02 '17 at 12:28
if you are using Angular, please check this [answer](https://stackoverflow.com/questions/12190166/angularjs-any-way-for-http-post-to-send-request-parameters-instead-of-json). — Fnayou, Jun 02 '17 at 15:25

For POST request is:

$request->request->get('foo');

Try to dump all the data in the request using `$request->request->all();`. – Ilario Pierbattista Jun 02 '17 at 12:16
it gave me array [0] – Parks Jun 02 '17 at 12:22
Can you post your javascript code and your definitions of routes too? – Ilario Pierbattista Jun 02 '17 at 12:23
For details: I'm using KunstmaanCMS, and in admin page created angular app (to update some general data using Ajax and not to build heavy interface with forms and other stuff) – Parks Jun 02 '17 at 12:25
My advice is to use a tool like [postman](https://chrome.google.com/webstore/detail/postman/fhbjgbiflinjbdggehcddcbncdddomop) to send post request to your controller. Don't forget to add `Content-Type: application/json` to yout header). – Ilario Pierbattista Jun 02 '17 at 12:30

Try using FormData for your client-side ajax's call

For example : try something like

var formData = new FormData();
formData.append('foo', 'bar')

  $http.post('http://url',
       formData
  );

Ok, I wasn't paying attention that you used json so, You wont get the content of $foo in request but you need to json_decode the $content

So by keeping the same way you sent data :

$http.post('http://admin/about-company/setJSONObj',
    {foo: 'bar'}
);

You just have to call

use Symfony\Component\HttpFoundation\Request;
use Sensio\Bundle\FrameworkExtraBundle\Configuration\Route;
use Sensio\Bundle\FrameworkExtraBundle\Configuration\Method;
    ...
    /**
    * @Route("/setJSONObj", name="admin_pages_set_ajax_obj")
    * @Method("POST")
    */
    public function updateAction(Request $request)
        {
             $foo = $request->get('foo'); // null
             $requestType = $request->getContentType(); // json
             $content = $request->getContent(); // {"foo":"bar"}
             $data = json_decode($content, true);
             dump($data['foo']); // "foo"
             //And you can know replace the data of the request. So
             $request->request->replace($data);

My guess is because symfony need have the 'Content-Type' 'application/x-www-form-urlencoded' but Angular by default have a application/json (so you can override the headers on the $http.post call.

The same, except $content = `------WebKitFormBoundaryHLFYNZeven585hAi Content-Disposition: form-data; name="foo" bar ------WebKitFormBoundaryHLFYNZeven585hAi--` — Parks, Jun 02 '17 at 12:39
thanks for variant, but things was already like you suggesting: 'json application-type' header sets AngularJS for request, and Symfony don't handle it — Parks, Jun 02 '17 at 13:26
json_decode - yes, it should work, but I'll use if not find better solution ) — Parks, Jun 02 '17 at 13:30
have you tried to change the header to `'application/x-www-form-urlencoded'` and use `new FormData()` ? This one should work — henrily, Jun 02 '17 at 13:37
yes, it changed $type = `form`, `...request->all()` gives same result as `$content` in 1st comment, but `...->get('foo')` gives `null`... — Parks, Jun 02 '17 at 16:19

It turned out, my mistake was to expect POST variables in $request->request->all(); while posting JSON: see explanation https://www.toptal.com/....

For creating REST api with Symfony it's normal to use FOSRestBundle: see body listener. So, it solves my problem in elegant way.

Also, @henrily suggested a workaroud somebody can use, but it's just a workaround.
