Create REST api in Symfony

A) Download the Bundle

Open a command console, enter your project directory and execute the following command to download the latest stable version of this bundle:

$ composer require friendsofsymfony/rest-bundle

B) Enable the Bundle

Then, enable the bundle by adding the following line in the app/AppKernel.php file of your project:

1  2  3  4  5  6  7  8  9 10 11 12 13

// app/AppKernel.php class AppKernel extends Kernel {     public function registerBundles()     {         $bundles = [             // ...             new FOS\RestBundle\FOSRestBundle(),         ];         // ...     } }

C) Enable a Serializer

This bundle needs a serializer to work correctly. In most cases, you'll need to enable a serializer or install one. This bundle tries the following (in the given order) to determine the serializer to use:

1.The one you configured using fos_rest.service.serializer (if you did).

2.The JMS serializer, if the JMSSerializerBundle is available (and registered).

3.The Symfony Serializer if it's enabled (or any service called serializer).

D) Update config.yml
