This is the official bundle of the SymfonyConnect SDK.
Step 1: Install symfony/connect-bundle using Composer
$ composer require symfonycorp/connect-bundleIf you're not using Symfony Flex, please take inspiration from this bundle's recipe to enable it.
SYMFONY_CONNECT_APP_ID='Your app id'
SYMFONY_CONNECT_APP_SECRET='Your app secret'Note: If you want to persist your users, read the Cookbooks section.
If you don't want to persist your users, you can use ConnectInMemoryUserProvider:
# config/packages/security.yaml
security:
providers:
symfony_connect:
connect_memory: ~
firewalls:
# [...]
secured_area:
pattern: ^/
symfony_connect:
check_path: symfony_connect_callback
login_path: symfony_connect_login
failure_path: home # need to be adapted to your config, see step 4
remember_me: false
provider: symfony_connect
anonymous: trueYou can also load specific roles for some users:
# config/packages/security.yaml
security:
providers:
symfony_connect:
connect_memory:
users:
90f28e69-9ce9-4a42-8b0e-e8c7fcc27713: "ROLE_CONNECT_USER ROLE_ADMIN"Note: The username is the user uuid.
You can generate a link to the SymfonyConnect login page:
<a href="{{ url('symfony_connect_login') }}">Connect</a>You can also specify the target URL after connection:
<a href="{{ url('symfony_connect_login') }}?target=XXX">Connect</a>The API user is available through the token storage, which you can get by autowiring
Symfony\Component\Security\Core\Authentication\Token\Storage\TokenStorageInterface $tokenStorage.
$user = $tokenStorage->getToken()->getApiUser();If you use the built-in security component, you can access to the root api
directly by autowiring SymfonyCorp\Connect\Api\Api $api:
$user = $api->getRoot()->getCurrentUser();
You can also get access to the API root object by providing an access token explicitly:
$accessToken = $tokenStorage->getToken()->getAccessToken();
$api->setAccessToken($accessToken);
$root = $api->getRoot();
$user = $root->getCurrentUser();Several errors can occur during the OAuth dance, for example the user can
deny your application or the scope you defined in symfony_connect.yaml can be different
from what you selected while creating your application on SymfonyConnect.
Theses failures arehandled by the default Symfony failure handling.
Therefore, if an error occurred, the error is stored in the session (with a
fallback on query attributes) and the user is redirected to the route/path
specificed in failure_path node of the symfony_connect section of your
firewall in security.yaml.
Warning: You need to specifiy
failure_path. If you don't, the user will be redirected back tologin_path, meaning that will launch the SymfonyConnect authentication and redirect the user to SymfonyConnect which can lead to a redirection loop.
This means you need to fetch the authentication error if there is one and display
it in the view. This is similar to what you do for a typical login form on
Symfony (here we assume you have a home route pointing to the following controller):
// src/Controller/HomeController.php
namespace App\Controller;
use Symfony\Bundle\FrameworkBundle\Controller\AbstractController;
use Symfony\Component\HttpFoundation\Request;
use Symfony\Component\Routing\Annotation\Route;
use Symfony\Component\Security\Core\Security;
class HomeController extends AbstractController
{
/**
* @Route("/", name="home")
*/
public function home(Request $request)
{
$session = $request->hasSession() ? $request->getSession() : null;
// get the authentication error if there is one
if ($request->attributes->has(Security::AUTHENTICATION_ERROR)) {
$error = $request->attributes->get(Security::AUTHENTICATION_ERROR);
} elseif (null !== $session && $session->has(Security::AUTHENTICATION_ERROR)) {
$error = $session->get(Security::AUTHENTICATION_ERROR);
$session->remove(Security::AUTHENTICATION_ERROR);
} else {
$error = '';
}
return $this->render('home.html.twig', ['error' => $error]);
}
}And then adapt your twig template:
{# templates/home.html.twig #}
{% if app.user %}
Congrats! You are authenticated with SymfonyConnect
{% elseif error %}
{{ error.messageKey | trans(error.messageData, 'security') }}
{% else %}
<a href="{{ url('symfony_connect_login') }}">Log in with SymfonyConnect</a>
{% endif %}<?php
