How to inject $_SERVER variable into a Service

Question

a service of my application needs to access a $_SERVER variable (which is provided by apache) called: $_SERVER['GEOIP_COUNTRY_CODE'];

What are good ways to achieve this?

My current guess would be to inject the RequestStack but on the other hand I dont want to couple the complete RequestStack to this service.

Are there other ways of achieving this?

P.S. Please don't answer me with links to bundles like https://github.com/aferrandini/Maxmind-GeoIp etc.

Which type is your service file? yml or xml? – Canser Yanbakan Jun 06 '14 at 08:16 — Canser Yanbakan, Jun 06 '14 at 08:16
I'm using yaml as file format. – gries Jun 06 '14 at 08:28 — gries, Jun 06 '14 at 08:28

You have to tell your service to inject the request stack to get current request.

You can call the request service but it is may cause a ScopeWideningInjectionException exception because the request can change.

Your service file:

<?php

namespace Some\GreatBundle\ServicePath;
use Symfony\Component\HttpFoundation\RequestStack;

class GreatService
{
    private $request;

    public function __construct(RequestStack $requestStack)
    {
        $this->request = $requestStack->getCurrentRequest();
    }

    public function getGeoIpCountryCode()
    {
        return $this->request->server->get("GEOIP_COUNTRY_CODE");
    }
}

YML:

services:
    your_great_service:
        class:     Some\GreatBundle\ServicePath\GreatService
        arguments: ["@request_stack"]

Maybe decouple the service with an extra geo ip service class from the request stack :) — Emii Khaos, Jun 06 '14 at 11:49

If I understands you, you want to use a $_SERVER variable in a service. I found this in the Symfony documentation:

use Symfony\Component\HttpFoundation\Request;

$request = Request::createFromGlobals();

// retrieve SERVER variables
$request->server->get('HTTP_HOST');

As I can see, there is no problem to achieve your variable:

$request->server->get('GEOIP_COUNTRY_CODE');

Yes, but I'm asking if there is an alternative for this, so I don't have to inject the complete RequestStack into the service. – gries Jun 06 '14 at 07:59
Sure, you can also use the old $_SERVER superglobal. – vobence Jun 06 '14 at 08:26
