Github WebHook Bundle

This bundle aiming to reduce complexity when creating GitHub web hooks apps.

Installation

The recommended way to install this bundle is through Composer:

composer require "swop/github-webhook-bundle"

Then, register the bundle into your AppKernel class. Note that this bundle rely on the SensioFrameworkExtraBundle bundle in order to work properly.

<?php

class AppKernel extends Kernel
{
    public function registerBundles()
    {
        $bundles = [
            // ...
            new Sensio\Bundle\FrameworkExtraBundle\SensioFrameworkExtraBundle(),
            new Swop\Bundle\GitHubWebHookBundle\GitHubWebHookBundle()
        ];

        // ...
    }
}

Usage

Simply use the GitHubWebHook annotation in your controllers to mark them as GitHub web hook controllers

<?php

namespace AppBundle\Controller;

use Sensio\Bundle\FrameworkExtraBundle\Configuration\Route;
use Swop\GitHubWebHook\Event\GitHubEvent;
use Symfony\Bundle\FrameworkBundle\Controller\Controller;
use Swop\Bundle\GitHubWebHookBundle\Annotation\GitHubWebHook;

class DefaultController extends Controller
{
    /**
     * @Route("/webhook", name="webhook")
     *
     * @GitHubWebHook(eventType="push")
     * @GitHubWebHook(eventType="pull_request")
     */
    public function indexAction(GitHubEvent $gitHubEvent)
    {
        $payload = $gitHubEvent->getPayload(); // Request payload (array)
        $eventType = $gitHubEvent->getType(); // "pull" or "pull_request"

        // Do something depending on the payload & the event type...
        
        return ['status' => 'success'];
    }
}

By declaring that your controller is a GitHub web hook, the bundle will make the following actions for you:

• It will check if the incoming web hook event is supported by your controller. If it's not the case, a 400 JSON response will be automatically returned.

• It will verify that the incoming request has a correct signature, using the web hook specific secret (see "Annotation reference") or the default one (see "Bundle configuration reference"). If the request signature is invalid, a 403 JSON response will be automatically returned.

• It will build a GitHubEvent object which will be injected in the controller parameters.

• It will manage the serialization of the data you returned in your controller, and thus will send back a 200 JSON response to GitHub.

Configuration

Bundle configuration reference

github_webhook:
    default_secret: my_secret

• default_secret: Default secret to use on every hooks when validating the incoming request signature.

Annotation reference

Simple event type handling (will respond only to the push event):

<?php
/**
 * @GitHubWebHook(eventType="push")
 */

Multiple event types handling (will respond to the push and pull_request event):

<?php
/**
 * @GitHubWebHook(eventType="push")
 * @GitHubWebHook(eventType="pull_request")
 */

Configure a dedicated secret to use for signature validation:

<?php
/**
 * @GitHubWebHook(eventType="push", secret="push_secret")
 * @GitHubWebHook(eventType="pull_request", secret="pr_secret")
 */

You also can rely on a container parameter to configure the secret to use:

<?php
/**
 * @GitHubWebHook(eventType="push", secret="%hook.push.secret%")
 */
