README
This package provides Slack OAuth 2.0 support for the PHP League's OAuth 2.0 Client.
Installation
To install, use composer:
composer require bramdevries/oauth2-slack
Usage
Usage is the same as The League's OAuth client, using \League\OAuth2\Client\Provider\Slack
as the provider.
Authorization Code Flow
$provider = new League\OAuth2\Client\Provider\Slack([ 'clientId' => '{slack-client-id}', 'clientSecret' => '{slack-client-secret}', 'redirectUri' => 'https://example.com/callback-url', ]); if (!isset($_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->getNickname()); } 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 Slack authorization URL, you can specify the state and scopes your application may authorize.
$options = [ 'state' => 'OPTIONAL_CUSTOM_CONFIGURED_STATE', 'scope' => ['identify','read','post'] // array or string ]; $authorizationUrl = $provider->getAuthorizationUrl($options);
If neither are defined, the provider will utilize internal defaults.
At the time of authoring this documentation, the following scopes are available.
- identify
- read
- post
- client
- admin
Testing
