## Installation

Add oauth-4-laravel to your composer.json file:

```
"require": {
  "artdarek/oauth-4-laravel": "dev-master"
}
```

Use composer to install this package.

```
$ composer update
```

## Configuration

There are two ways to configure oauth-4-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-4-laravel.php`` in 
your ``app\config\`` directory (option 2).

#### Option 1

Create configuration file for package using artisan command

```
$ php artisan config:publish artdarek/oauth-4-laravel
```

#### Option 2

Create configuration file manually in config directory ``app/config/oauth-4-laravel.php`` and put there code from below.

```php
return array( 
	
	/*
	|--------------------------------------------------------------------------
	| oAuth Config
	|--------------------------------------------------------------------------
	*/

	/**
	 * Storage
	 */
	'storage' => 'Session', 

	/**
	 * Consumers
	 */
	'consumers' => array(

		/**
		 * Facebook
		 */
		'Facebook' => array(
		    'client_id'     => '',
		    'client_secret' => '',
		    'scope'         => array(),
		),		

	)

);
```


### Registering the Package

Add an alias to the bottom of app/config/app.php

```php
'OAuth' => 'Artdarek\OAuth\Facade\OAuth',
```

and register this service provider at the bottom of the `$providers` array:

```php
'Artdarek\OAuth\OAuthServiceProvider',
```

### Credentials

Add your credentials to ``app/config/packages/artdarek/oauth-4-laravel/config.php`` or ``app/config/oauth-4-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:

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

## Usage examples

###Facebook:

Configuration:
Add your Facebook credentials to ``app/config/packages/artdarek/oauth-4-laravel/config.php``

```php

    'client_secret' => 'Your Facebook Client Secret',
    'scope'         => array('email','read_friendlists','user_online_presence'),
),	
```
In your Controller use the following code:

```php
/**
 * Login user with facebook
 *
 * @return void
 */

public function loginWithFacebook() {
	
	// get data from input
	$code = Input::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 ( !empty( $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
	else {
		// get fb authorization
