How to integrate OAuth2 authentication to REST API library

Dear Friends,

I am using Simple-REST Library for my REST Web service purpose . I need to integrate "OAuth2.0" with my REST API skeleton.

I attached the REST - API Client & Server for your reference . Please check it and help me with a good solution for implementation.

The code of attached "simple_rest_client->index.php" as follows:

<?php

	$ch = curl_init();


	curl_setopt($ch, CURLOPT_URL, "http://localhost/simple_rest_master/test");

	curl_setopt($ch, CURLOPT_HEADER, 0);

	curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);

	curl_setopt($ch, CURLOPT_POST, 1);


	$data = array(

		'username' => 'foo',

		'password' => 'bar'

	);


	curl_setopt($ch, CURLOPT_POSTFIELDS, $data);


	$contents = curl_exec($ch);


	curl_close($ch);


	echo $contents;





?> 

Here the client call the Controller method "Test" as in cURL http://localhost/simple_rest_master/test. It's URL in localhost is : http://localhost/simple_rest_client/

I also add the code of "Server" in zip file as "simple_rest_master.zip".

In this case I need to implement the authentication using OAuth2.0 .

I looked the RFC standard for it here : http://tools.ietf.org/html/rfc6749

Please help,

Thanks,

Anes
