Get data on a PUT route using Silex

Question

I would like to know how to obtain data passed to a route put using the Silex. For example :

$app->put('foo/{id}', function(Request $request, $id) use ($app){
  return var_dump($request->get('bar')); //return null 
});

This returns NULL, someone knows a way to get the data passed by the request ?

Answer 1

According to the documentation of Silex, you have to instruct your application to accept a request via JSON:

use Symfony\Component\HttpFoundation\Request;
use Symfony\Component\HttpFoundation\ParameterBag;

$app->before(function (Request $request) {
    if (0 === strpos($request->headers->get('Content-Type'), 'application/json')) {
        $data = json_decode($request->getContent(), true);
        $request->request->replace(is_array($data) ? $data : array());
    }
});

Edit: follows a functional example:

<?php

require_once __DIR__.'/../vendor/autoload.php';

use Symfony\Component\HttpFoundation\Request;

$app = new Silex\Application();

$app->before(function(Request $request) {
    if (0 === strpos($request->headers->get('Content-Type'), 'application/json')) {
        $data = json_decode($request->getContent(), true);
        $request->request->replace(is_array($data) ? $data : []);
    }
});

$app->put('/foo/{id}', function(Request $request, $id) use($app) {
    var_dump($request->request->all()); die;
});

$app->run();

I used the Httpie to test the request:

$ echo '{ "lala": "lele" }' | http PUT silex.dev/foo/1
