laravel-restcord (Laravel 8)

The repository is a fork of more-cores/laravel-restcord, it was updated to be compatible with PHP 8 and recent versions of Laravel.

A small, fluent wrapper for Restcord.

Features

Integrates Restcord with Laravel Socialite so currently OAuth'd user is used for api calls (when sessionHasDiscordToken middleware is used)
Handles creation of webhooks via OAuth (no bot required)
Handles adding bots to to guilds via OAuth (no websocket connection required)
Obtain information about a member's relationship with a guild (roles, permissions, etc.)

Installation

Install package

composer require more-cores/laravel-restcord:2.*

Define the DISCORD_BOT_TOKEN environmental variable.
Add the middleware sessionHasDiscordToken for the routes where you need to use the current OAuth'd user's credentials to interact with the Discord API. This is required because session information is not available in a ServiceProvider.
For Laravel <= 5.4, register the service provider in config/app.php

'providers' => [
    ...
    LaravelRestcord\ServiceProvider::class,
]

Environment Variables

DISCORD_BOT_KEY
DISCORD_BOT_SECRET
DISCORD_BOT_TOKEN
DISCORD_KEY
DISCORD_SECRET

Bot key/secret will be used for callback endpoints related to adding a bot or creating a webhook as well as when the application is running in the console such as queue workers and cron.

Usage

This documentation assumes your users are logging in via the Discord driver for Laravel Socialite.

Anytime you see $discord in this documentation it is assumed to be an instance of LaravelRestcord\Discord\Discord::class which is available from Laravel's IOC container.

Guilds

Get a list of guilds the current user has access to:

$discord->guilds() // Guild[]

Get information about a user's relationship with a guild

$guild->userCan(Permission::KICK_MEMBERS); // bool - uses permissions of the currently oauth'd user

$member = $guild->getMemberById($discordUserId); // \LaravelRestcord\Discord\Member
$member->roles(); // \LaravelRestcord\Discord\Role[]
$member->joinedAt(); // Carbon

Adding Bots To Guilds

This implementation uses the Advanced Bot Authorization flow to add the bot to a guild. You should have the Require OAuth2 Code Grant option enabled on your app's settings.

use LaravelRestcord\Discord\HandlesBotAddedToGuild;
use Illuminate\Http\RedirectResponse;

class BotAddedToDiscordGuild
{
    use HandlesBotAddedToGuild;
    
    public function botAdded(Guild $guild) : RedirectResponse
    {
        // do something with the guild information the bot was added to
        
        return redirect('/to/this/page');
    }
}

Next, add a binding to your AppServiceProvider so the package knows which class to pass the guild information to when the user returns to your web site.

 $this->app->bind(HandlesBotAddedToGuild::class, BotAddedToDiscordGuild::class);

Now you're ready to direct the user to Discord's web site so they can select the guild to add the bot to:

    public function redirecToAddBot(Guild $guild = null)
    {
        // Reference https://discordapi.com/permissions.html to determine
        // the permissions your bot needs
        Discord::redirecToAddBot($permissions, $guild->?id()??null);
    }

if you wan to show a button in th ui

    public function redirecToAddBot(Guild $guild = null)
    {
        // Reference https://discordapi.com/permissions.html to determine
        // the permissions your bot needs
        $url = Discord::addBotUrl($permissions, $guild->?id()??null);
        return $url;
        // show this in href link
    }

This package handles the routing needs, but you need to whitelist the callback URL for this to work. Add http://MY-SITE.com/discord/bot-added to your application's redirect uris.

Your handler will be trigger when the bot has been added to a guild.

You will be able to send messages via this bot once it has established a web socket connection. It only has to do this once, so it's a common practice to use the below code snippet to do so:

"use strict";
var TOKEN="PUT YOUR TOKEN HERE";
fetch("https://discord.com/api/v7/gateway").then(function(a){return a.json()}).then(function(a){var b=new WebSocket(a.url+"/?encoding=json&v=6");b.onerror=function(a){return console.error(a)},b.onmessage=function(a){try{var c=JSON.parse(a.data);0===c.op&&"READY"===c.t&&(b.close(),console.log("Successful authentication! You may now close this window!")),10===c.op&&b.send(JSON.stringify({op:2,d:{token:TOKEN,properties:{$browser:"b1nzy is a meme"},large_threshold:50}}))}catch(a){console.error(a)}}});

Creating Webhooks

Because we're using OAuth to create webhooks, the user will be directed to Discord's web site to select the guild/channel. This package handles interpreting the request/response lifecycle for this, so all you need to do is build a handler:

use LaravelRestcord\Discord\HandlesDiscordWebhooksBeingCreated;
use Illuminate\Http\RedirectResponse;

class Subscribe
{
    use HandlesDiscordWebhooksBeingCreated;
    
    public function webhookCreated(Webhook $webhook) : RedirectResponse
    {
        // $webhook->token();
        // Here you should save the token for use later when activating the webhook
        
        return redirect('/to/this/page');
    }
}

Next, add a binding to your AppServiceProvider so the package knows which class to pass the webhook data to when the user returns to your web site.

 $this->app->bind(HandlesDiscordWebhooksBeingCreated::class, DiscordChannelAdded::class);

Now you're ready to direct the user to Discord's web site to create the webhook:

    public function createWebhook()
    {
        // redirects the user to Discord's interface for selecting
        // a guild and channel for the webhook
        Discord::redirectToCreateWebhook();
        //for url
        $url = Discord::addWebHookUrl();
    }

This package handles the routing needs, but you need to whitelist the callback URL for this to work. Add http://MY-SITE.com/discord/create-webhook to your application's redirect uris.

Your handler will be trigger when the webhook is created.
