I'm trying to get Slim setup and working, and am using Postman (in Chrome) to test Slim calls but cant figure out how to get any of the posted JSON data.

Im submitting raw JSON:

{name":"John Smith", "age":"30", "gender

With Content-Type: application/json in the header

via POST to:


Every attempt to get the JSON data gives a fatal error (see code comments below)

require 'vendor/autoload.php';
$app = new \Slim\Slim(); $app->add(new \Slim\Middleware\ContentTypes());

$app->group('/api/v1', function () use ($app) {

$app->group('/users/post', function () use ($app) {

    $app->post('/test/', function () {

            print_r($app->request->headers); //no errors, but no output?

            echo "Hello!"; // outputs as expected

            $data = $app->request()->params('name'); //Fatal error: Call to a member function request() on a non-object
            $data = $app->request->getBody(); //Fatal error: Call to a member function getBody() on a non-object
            $data = $app->request->post('name'); //Fatal error: Call to a member function post() on a non-object
            $data = $app->request()->post(); //Fatal error: Call to a member function request() on a non-object




$app->run(); ?>

Status is 200. What am I doing wrong? :0

    Sorry, but as was pointed out by someone on another forum, the problem ended up being an issue with how I was interpreting the docs.

    $app->post('/test/', function () {

    Should be:

    $app->post('/test/', function () use ($app) {

    My bad. Carry on!

    Its not about the post function. Its about how to read the json request from the client.
    For your info, there is no problem when using the application/x-www-form-urlencoded. Only facing the issue when handle/read the json request.
    i am also facing the same issue by reading json request.

    $request = $app->request();
        $body    = $request->getBody();
        $input   = array(json_decode($body,true));

    this doesn't help at all.
    Why not post example of the code how to read json request. It will be a pleasure for us.
