Cant get JSON POST data submitted via Slim

Question

Im 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":"male"}

With Content-Type: application/json in the header

via POST to:

http://domain/api/v1/users/post/test/

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

<?php
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 just fine

        $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

                print_r($data);
                echo $data;

        });

    });

});

$app->run();
?>

What am I missing?

Thanks!

Answer 1

Make sure to curry $app into the last nested route, like so:

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

You're doing it everywhere else, so I'm assuming you just overlooked it.

Answer 2

you have to get the body from the request:

$app->request->getBody();

http://docs.slimframework.com/request/body/

Answer 3

In Slim 3 I've used the value of body in curl POST data and it didn't work, to fix this I've used this, the body is object not string:

$app->post('/proxy', function($request, $response) {
    $data = $request->getBody()->getContents();
    $response->getBody()->write(post('http://example.com', $data));
});

You can check more methods on body in docs
