Laravel 5 create middleware with oauth2 server check - laravel

Question

I have implemented this oauth server http://bshaffer.github.io/oauth2-server-php-docs/
It has a Laravel implementation : http://bshaffer.github.io/oauth2-server-php-docs/cookbook/laravel/
This guide you and gives that code for routes :
App::singleton('oauth2', function() {
$storage = new OAuth2\Storage\Pdo(array('dsn' => 'mysql:dbname=oauth2;host=localhost', 'username' => 'root', 'password' => 'root'));
$server = new OAuth2\Server($storage);
$server->addGrantType(new OAuth2\GrantType\ClientCredentials($storage));
$server->addGrantType(new OAuth2\GrantType\UserCredentials($storage));
return $server;
});
Route::get('private', function()
{
$bridgedRequest = OAuth2\HttpFoundationBridge\Request::createFromRequest(Request::instance());
$bridgedResponse = new OAuth2\HttpFoundationBridge\Response();
// fix for laravel
$bridgedRequest->request = new \Symfony\Component\HttpFoundation\ParameterBag();
$rawHeaders = getallheaders();
if (isset($rawHeaders["Authorization"])) {
$authorizationHeader = $rawHeaders["Authorization"];
$bridgedRequest->headers->add([ 'Authorization' => $authorizationHeader]);
}
if (App::make('oauth2')->verifyResourceRequest($bridgedRequest, $bridgedResponse)) {
$token = App::make('oauth2')->getAccessTokenData($bridgedRequest);
return Response::json(array(
'private' => 'stuff',
'user_id' => $token['user_id'],
'client' => $token['client_id'],
'expires' => $token['expires'],
));
}
else {
return Response::json(array(
'error' => 'Unauthorized'
), $bridgedResponse->getStatusCode());
}
});
It works perfectly well like that. Now I want to transform that check function in the "private" route to a middleware I could apply to each necessary route. I created the middleware using
php artisan make:middleware AuthChecker
Added it to the kernel.php, and pasted the code of the verification function inside of it. And I immediately got an error :
FatalErrorException in AuthChecker.php line 17:
Class 'Oauth2\HttpFoundationBridge\Request' not found
So, I guess I will have to "use" things, but since I'm still a beginner I don't really know what to do...
Thanks ahead for your help !
[EDIT] the content of the middleware currently look like this :
namespace App\Http\Middleware;
use Closure;
class OauthCheck {
public function handle($request, Closure $next)
{
$bridgedRequest = OAuth2\HttpFoundationBridge\Request::createFromRequest($request);
$bridgedResponse = new OAuth2\HttpFoundationBridge\Response();
// fix for laravel
$bridgedRequest->request = new \Symfony\Component\HttpFoundation\ParameterBag();
$rawHeaders = getallheaders();
if (isset($rawHeaders["Authorization"])) {
$authorizationHeader = $rawHeaders["Authorization"];
$bridgedRequest->headers->add([ 'Authorization' => $authorizationHeader]);
}
if (App::make('oauth2')->verifyResourceRequest($bridgedRequest, $bridgedResponse)) {
$token = App::make('oauth2')->getAccessTokenData($bridgedRequest);
return Response::json(array(
'private' => 'stuff',
'user_id' => $token['user_id'],
'client' => $token['client_id'],
'expires' => $token['expires'],
));
return $next($request);
}
else {
return Response::json(array(
'error' => 'Unauthorized'
), $bridgedResponse->getStatusCode());
}
}
}
Thanks again

FatalErrorException in AuthChecker.php line 17:
Class 'Oauth2\HttpFoundationBridge\Request' not found
So you want to use the Request class from Oauth2\HttpFoundationBridge namespace to your OauthCheck class from App\Http\Middleware.
You can do it in either ways:
Import the class
namespace App\Http\Middleware;
use Oauth2\HttpFoundationBridge\Request;
class OauthCheck {
public function handle($request, Closure $next)
{
$bridgedRequest = Request::createFromRequest($request);
....
}
}
Use the class explicitly
namespace App\Http\Middleware;
class OauthCheck {
public function handle($request, Closure $next)
{
$bridgedRequest = \Oauth2\HttpFoundationBridge\Request::createFromRequest($request);
....
}
}
Take note of the backslash before Oauth2\HttpFoundationBridge\Request. If you just say $bridgedRequest = Oauth2\HttpFoundationBridge\Request, then PHP will look for App\Http\Middleware\Oauth2\HttpFoundationBridge\Request.
