Backbone.js和REST API与Silex（PHP）

Question

lets say I have a model called John with those params:

{
    Language : {
        code    :  'gr',
        title   :  'Greek'
    },
    Name : 'john'
}

So now when I trigger John.save() it POST those to server:

post params http://o7.no/ypvWNp

with those headers:

headers http://o7.no/x5DVw0

The code in Silex is really simple:

<?php

require_once __DIR__.'/silex.phar';

$app = new Silex\Application();

use Symfony\Component\HttpFoundation\Request;
use Symfony\Component\HttpFoundation\Response;

// definitions
$app['debug'] = true;

$app->post('/api/user', function (Request $request) {
    var_dump($request->get('Name'));

    $params = json_decode(file_get_contents('php://input'));
    var_dump($params->Name);
});

$app->run();

but first var_dump return null second var_dump of course works since I'm getting the request directly from php://input resource. I'm wondering how I could get the params using Request object from Silex

Thanks

It's pretty easy actually.

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);
        $request->request = new ParameterBag(is_array($data) ? $data : array());
    }
});

And then an example route:

$app->match('/', function (Request $request) {
    return $request->get('foo');
});

And testing with curl:

$ curl http://localhost/foobarbazapp/app.php -d '{"foo": "bar"}' -H 'Content-Type: application/json'
bar
$

Alternatively look at the (slightly outdated) RestServiceProvider.
