This package provides [Phabricator](https://www.phacility.com/) OAuth 2.0 support for the PHP League's [OAuth 2.0 Client](https://github.com/thephpleague/oauth2-client).

## Updates

The project is considered in a usable state and feature complete.

This project is used in corporate applications. As such, the authors are unlikely to update it on a regular basis, but instead when the corporate applications that use it run into problems. You should expect updates in the 5-10yr range.

Issues and PRs will be monitored, and we will continue to work with the community to provide updates as they are contributed.

## Installation

To install, use composer:

```
composer require ofbeaton/oauth2-phabricator
```

## Usage

Usage is the same as The League's OAuth client, using `\Ofbeaton\OAuth2\Client\Provider\Phabricator` as the provider.

### With oauth2-client bundles

[Symfony Bundles](http://symfony.com/) like [knpuniversity's oauth2-client-bundle](https://github.com/knpuniversity/oauth2-client-bundle) or [HWIOAuthBundle](https://github.com/hwi/HWIOAuthBundle) use the PHP League's [OAuth 2.0 Client](https://github.com/thephpleague/oauth2-client) under the hood.

It is vital that you pass the domain for your phabricator install. For knpuniversity's oauth2-client-bundle this means in your Symfony `config.yml` you want this instead:

```yml
knpu_oauth2_client:
clients:
phabricator_oauth:
type: generic
provider_class: Ofbeaton\OAuth2\Client\Provider\Phabricator

provider_options:
domain: %phab_host%

client_id: %phab_client_id%
client_secret: %phab_client_secret%
redirect_route: connect_phabricator_check
redirect_params: {}
```

### Authorization Code Flow

```php
$provider = new Ofbeaton\OAuth2\Client\Provider\Phabricator([
'domain' => 'https://your-phabricator-install.com',
'clientId' => '{phabricator-client-id}',
'clientSecret' => '{phabricator-client-secret}',
'redirectUri' => 'https://your-application.com/callback-url',
]);

if (!isset($_GET['code'])) {

// If we don't have an authorization code then get one
$authUrl = $provider->getAuthorizationUrl();
$_SESSION['oauth2state'] = $provider->getState();
header('Location: '.$authUrl);
exit;

// Check given state against previously stored one to mitigate CSRF attack
} elseif (empty($_GET['state']) || ($_GET['state'] !== $_SESSION['oauth2state'])) {

unset($_SESSION['oauth2state']);
exit('Invalid state');

} else {

// Try to get an access token (using the authorization code grant)
$token = $provider->getAccessToken('authorization_code', [
'code' => $_GET['code']
]);

// Optional: Now you have a token you can look up a users profile data
try {

// We got an access token, let's now get the user's details
$user = $provider->getResourceOwner($token);

// Use these details to create a new profile
printf('Hello %s!', $user->getRealName());

} catch (Exception $e) {

// Failed to get user details
exit('Oh dear...');
}

// Use this to interact with an API on the users behalf
echo $token->getToken();
}
```

### Managing Scopes

When creating your Phabricator authorization URL, you can specify the state and scopes your application may authorize.

```php
$options = [
'state' => 'OPTIONAL_CUSTOM_CONFIGURED_STATE',
'scope' => ['user','user:email','repo'] // array or string
];

$authorizationUrl = $provider->getAuthorizationUrl($options);
```
If neither are defined, the provider will utilize internal defaults.

At the time of authoring this documentation, [no scopes are available](https://secure.phabricator.com/book/phabcontrib/article/using_oauthserver/).

## Testing

``` bash
$ ./vendor/bin/phpunit
