# OAuth wrapper for Laravel 5

oauth-5-laravel is a simple laravel 5 service provider (wrapper) for [Lusitanian/PHPoAuthLib](https://github.com/Lusitanian/PHPoAuthLib) 
which provides oAuth support in PHP 5.4+ and is very easy to integrate with any project which requires an oAuth client.

Was first developed by [Artdarek](https://github.com/artdarek/oauth-4-laravel) for Laravel 4 and I ported it to Laravel 5.

## Installation

Add oauth-5-laravel to your composer.json file:

```
"require": {
  "oriceon/oauth-5-laravel": "dev-master"
}
```

Use composer to install this package.

```
$ composer update
```

### Registering the Package

Register the service provider within the ```providers``` array found in ```config/app.php```:

```php
'providers' => [
	// ...
	
	Artdarek\OAuth\OAuthServiceProvider::class,
]
```

Add an alias within the ```aliases``` array found in ```config/app.php```:


```php
'aliases' => [
	// ...
	
	'OAuth'     => Artdarek\OAuth\Facade\OAuth::class,
]
```

## Configuration

There are two ways to configure oauth-5-laravel.
You can choose the most convenient way for you. 
You can use package config file which can be 
generated through command line by artisan (option 1) or 
you can simply create a config file called ``oauth-5-laravel.php`` in 
your ``config`` directory (option 2).

#### Option 1

Create configuration file for package using artisan command

```
$ php artisan vendor:publish
```

#### Option 2

Create configuration file manually in config directory ``config/oauth-5-laravel.php`` and put there code from below.

```php
<?php

use OAuth\Common\Storage\Session;

return [ 
	
	/*
	|--------------------------------------------------------------------------
	| oAuth Config
	|--------------------------------------------------------------------------
	*/

	/**
	 * Storage
	 */
	'storage' => new Session(), 

	/**
	 * Consumers
	 */
	'consumers' => [

		/**
		 * Facebook
		 */
		'Facebook' => [
		    'client_id'     => '',
		    'client_secret' => '',
		    'scope'         => [],
		],		

	]

];
```

### Credentials

Add your credentials to ``config/oauth-5-laravel.php`` (depending on which option of configuration you choose)


The `Storage` attribute is optional and defaults to `Session`. 
Other [options](https://github.com/Lusitanian/PHPoAuthLib/tree/master/src/OAuth/Common/Storage).

## Usage

### Basic usage

Just follow the steps below and you will be able to get a [service class object](https://github.com/Lusitanian/PHPoAuthLib/tree/master/src/OAuth/OAuth2/Service) with this one rule:

```php
$fb = \OAuth::consumer('Facebook');
```

Optionally, add a second parameter with the URL which the service needs to redirect to, otherwise it will redirect to the current URL.

```php
$fb = \OAuth::consumer('Facebook', 'http://url.to.redirect.to');
```

## Usage examples

###Facebook:

Configuration:
Add your Facebook credentials to ``config/oauth-5-laravel.php``

    'scope'         => ['email','read_friendlists','user_online_presence'],
],	
```
In your Controller use the following code:

```php

public function loginWithFacebook(Request $request)
{
	// get data from request
	$code = $request->get('code');
	
	// get fb service
	$fb = \OAuth::consumer('Facebook');
	
	// check if code is valid
	
	// if code is provided get user data and sign in
	if ( ! is_null($code))
	{
		// This was a callback request from facebook, get the token
		$token = $fb->requestAccessToken($code);
		
		// Send a request with it
		$result = json_decode($fb->request('/me'), true);
		
		$message = 'Your unique facebook user id is: ' . $result['id'] . ' and your name is ' . $result['name'];
		echo $message. "<br/>";
		
		//Var_dump
		//display whole array.
		dd($result);
	}
	// if not ask for permission first
