Silex passing app and request to controller classes
I want a simple way to access $app and $request in my controller classes. The document says to do this,
public function action(Application $app, Request $request) {
// Do something.
}
but it doesn't look right to have to inject $app and $request to every method. Is there a way to include $app and $request to every controller by default, maybe using the constructor? I'd like to be able to use it as $this->app.
Thanks.
在Controllers as Services部分的文档中，您可以看到如何通过构造函数向控制器类注入依赖项 - 在这种情况下是存储库。
It's possible :
Create a ControllerResolver.php somewhere in your project and put this inside :
namespace MyProject;
use SilexControllerResolver as BaseControllerResolver;
class ControllerResolver extends BaseControllerResolver
{
protected function instantiateController($class)
{
return new $class($this->app);
}
}
Then register it in your app (before $app->run(); ):
$app['resolver'] = function ($app) {
return new MyProjectControllerResolver($app, $app['logger']);
};
Now you can create a base controller for your app, for example :
namespace MyProject;
use SilexApplication;
use SymfonyComponentHttpFoundationResponse;
abstract class BaseController
{
public $app;
public function __construct(Application $app)
{
$this->app = $app;
}
public function getParam($key)
{
$postParams = $this->app['request_stack']->getCurrentRequest()->request->all();
$getParams = $this->app['request_stack']->getCurrentRequest()->query->all();
if (isset($postParams[$key])) {
return $postParams[$key];
} elseif (isset($getParams[$key])) {
return $getParams[$key];
} else {
return null;
}
}
public function render($view, array $parameters = array())
{
$response = new Response();
return $response->setContent($this->app['twig']->render($view, $parameters));
}
}
And extend it :
class HomeController extends BaseController
{
public function indexAction()
{
// now you can use $this->app
return $this->render('home.html.twig');
}
}
