symfony3: create a restful api controller

We want to implement a basic api controller and a client to test it.

create a controller in your bundle.
Save it to AppBundle/controllers/Api/UserController.php
edit you routing under app/config/routing.yml and add the app_api part

At that point the api controller is available unter "localhost:8000/api/user"

But we wan to write a short testfile, to test our api with gusszle.

add guzzle to your composer composer 
cmd->require eightpoints/guzzle-bundle

This loads guzzle.

Create a file named test.php in your project root
open a terminal an hit the file:
php test.php

You will get your controller response directly.
