How get Session in console?

[genby8]

I use Symfony 5.3.6 PHP 7.4.14
i inject $requestStack in constructor my command class.

in method execute i call $requestStack->getCurrentRequest()->getSession(), but getCurrentRequest() return null.
How get session? SessionInterface is deprecated

In Console commands there's no HTTP context, so there are no requests and no sessions. It's mentioned here: https://symfony.com/doc/current/routing.html#generating-urls-in-commands

If you want to control the browser programmatically with a console command, see https://github.com/symfony/panther

To get the session and have all listeners function you could try the following (taken from HttpKernel::handleRaw())

$request = new Request();
$this->requestStack->push($request);

$event = new RequestEvent($httpKernel, $request, HttpKernelInterface::MAIN_REQUEST);
$this->dispatcher->dispatch($event, KernelEvents::REQUEST);

Original:

symfony/src/Symfony/Component/HttpKernel/HttpKernel.php

Lines 126 to 132 in e40e293

	private function handleRaw(Request $request, int $type = self::MAIN_REQUEST): Response
	{
	$this->requestStack->push($request);
	// request
	$event = new RequestEvent($this, $request, $type);
	$this->dispatcher->dispatch($event, KernelEvents::REQUEST);

Thanks for the advice. But doesn't it seem like duplication of code? Copying a piece of code from a version of a package is wrong in every way.

Symfony has wrapped container handling using autowiring. Now it is reasonable to prohibit making public services. Therefore, you need functionality out of the box, and not initiate the main request somewhere in a self-written service.
If I use the code described above in the service, then the firewall will fire (and anything can happen here). If I use subqueries without the main query, then this is strange.

I came to the conclusion that there is no such functionality at the current time (v. 5.3.x and higher).

You can create an event listener or subscriber that sets this for every command, or based on a criteria for a command. See: https://symfony.com/doc/current/components/console/events.html

The problem here is not that you have to copy-paste the code, the problem is that you're trying to use something designed to be used in the context of webserver requests in an environment where they don't exist.

Calling command code from a web request is not recommended either. If you want to share code between the web and cli, move the code to a shared dependency. These dependencies should not depend on the http-foundation and console components.

Проблема здесь не в том, что вам нужно копировать-вставить код, проблема в том, что вы пытаетесь использовать что-то, предназначенное для использования в контексте запросов веб-сервера в среде, где они не существуют.

We're talking about session and not about cookies, right?

We're talking about session and not about cookies, right?

Symfony\Component\HttpFoundation\Session\Session which is from the http-foundation. While sessions use a cookie to identify the session id from the client, sessions are designed to carry information across web requests regardless of how the session id is stored.

You can make it work on the cli, but this is "use at your own risk".
