README

Requirements

- PHP 7.3
- PHP 7.4
- PHP 8.0
- PHP 8.1
- PHP 8.2
Installation
To install, use composer:
$ composer require wohali/oauth2-discord-new
Usage
Usage is the same as The League's OAuth client, using \Wohali\OAuth2\Client\Provider\Discord
as the provider.
Sample Authorization Code Flow
This self-contained example:
- Gets an authorization code
- Gets an access token using the provided authorization code
- Looks up the user's profile with the provided access token
You can try this script by registering a Discord App with a redirect URI to your server's copy of this sample script. Then, place the Discord app's client id and secret, along with that same URI, into the settings at the top of the script.
<?php require __DIR__ . '/vendor/autoload.php'; session_start(); echo ('Main screen turn on!<br/><br/>'); $provider = new \Wohali\OAuth2\Client\Provider\Discord([ 'clientId' => '{discord-client-id}', 'clientSecret' => '{discord-client-secret}', 'redirectUri' => '{your-server-uri-to-this-script-here}' ]); if (!isset($_GET['code'])) { // Step 1. Get authorization code $authUrl = $provider->getAuthorizationUrl(); $_SESSION['oauth2state'] = $provider->getState(); header('Location: ' . $authUrl); // Check given state against previously stored one to mitigate CSRF attack } elseif (empty($_GET['state']) || ($_GET['state'] !== $_SESSION['oauth2state'])) { unset($_SESSION['oauth2state']); exit('Invalid state'); } else { // Step 2. Get an access token using the provided authorization code $token = $provider->getAccessToken('authorization_code', [ 'code' => $_GET['code'] ]); // Show some token details echo '<h2>Token details:</h2>'; echo 'Token: ' . $token->getToken() . "<br/>"; echo 'Refresh token: ' . $token->getRefreshToken() . "<br/>"; echo 'Expires: ' . $token->getExpires() . " - "; echo ($token->hasExpired() ? 'expired' : 'not expired') . "<br/>"; // Step 3. (Optional) Look up the user's profile with the provided token try { $user = $provider->getResourceOwner($token); echo '<h2>Resource owner details:</h2>'; printf('Hello %s#%s!<br/><br/>', $user->getUsername(), $user->getDiscriminator()); var_export($user->toArray()); } catch (Exception $e) { // Failed to get user details exit('Oh dear...'); } }
Managing Scopes
When creating your Discord authorization URL in Step 1, you can specify the state and scopes your application may authorize.
$options = [ 'state' => 'OPTIONAL_CUSTOM_CONFIGURED_STATE', 'scope' => ['identify', 'email', '...'] // 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:
- bot
- connections
- identify
- guilds
- guilds.join
- gdm.join
- messages.read
- rpc
- rpc.api
- rpc.notifications.read
- webhook.incoming
Refreshing a Token
You can refresh an expired token using a refresh token rather than going through the entire process of obtaining a brand new token. To do so, simply reuse the fresh token from your data store to request a refresh:
// create $provider as in the initial example $existingAccessToken = getAccessTokenFromYourDataStore(); if ($existingAccessToken->hasExpired()) { $newAccessToken = $provider->getAccessToken('refresh_token', [ 'refresh_token' => $existingAccessToken->getRefreshToken() ]); // Purge old access token and store new access token to your data store. }
Client Credentials Grant
Discord provides a client credentials flow for bot developers to get their own bearer tokens for testing purposes. This returns an access token for the bot owner:
// create $provider as in the initial example try { // Try to get an access token using the client credentials grant. $accessToken = $provider->getAccessToken('client_credentials'); } catch (\League\OAuth2\Client\Provider\Exception\IdentityProviderException $e) { // Failed to get the access token exit($e->getMessage()); }
Bot Authorization
To authorize a bot, specify a scope of bot
and set permissions appropriately:
// create $provider as in the initial example $options = [ 'scope' => ['bot'], 'permissions' => 1 ]; $authorizationUrl = $provider->getAuthorizationUrl($options); // Redirect user to authorization page header('Location: ' . $authUrl);
