Introduction

The RPurinton Discord OAuth2 Library is a PHP library designed to facilitate OAuth2 authentication with Discord. It provides functionality for obtaining and refreshing access tokens using Discord's API.

Installation

Composer Installation

To install the library, use Composer:

composer require rpurinton/discordoauth2

Configuration Setup

1. Create a config directory at the same level as the vendor directory.
2. Place the DiscordOAuth2.json file with your credentials in the config directory.
   • Note: The access_token, refresh_token, and expires_at will be added later by the library.

Discord Developer Portal Setup

1. Create a Discord application in the Discord Developer Portal.
2. Enable OAuth2 and set up the necessary redirect URIs.
3. Obtain the client ID and client secret.
4. Download the credentials JSON file and place it in the config directory as DiscordOAuth2.json.

Usage

Initialization

• Create a new instance of the DiscordOAuth2 class.
• Run the ->init() method to start the OAuth2 authentication flow.
• This method will redirect to Discord for authentication and back to your script with the authorization code.
• The init() method is crucial for the first-time setup to obtain the access_token and refresh_token.
• These tokens are stored in the DiscordOAuth2.json configuration file.
• Once the tokens are obtained, the init() method is not required again unless the user deauthorizes the app from their Discord account.

API Methods

• init(): Initiates the OAuth2 flow to obtain access and refresh tokens.
• refresh_token(): Refreshes the access token using the refresh token.

Examples

<?php
require 'vendor/autoload.php';

use RPurinton\DiscordOAuth2\DiscordOAuth2;

$discord = new DiscordOAuth2();
$discord->init(); // Only needed for the first-time setup

Troubleshooting

• Ensure that the DiscordOAuth2.json file is correctly configured and accessible.
• Verify that the Discord application is set up with the correct credentials and permissions.
• If you encounter issues with token expiration, ensure the refresh_token is valid and the init() method was successfully executed initially.
