How to get request header values in symfony
If you need to get a specific header you can use:
$request->headers->get('My-Header');
See documentation: https://symfony.com/doc/current/components/http_foundation.html#accessing-accept-headers-data
You need to pass your Request object to the controller method and then in controller use $request->headers->all()
For example:
public function testAction(Request $request)
{
$headers = $request->headers->all();
}
You can also get Request object from a controller by calling $this->getRequest()
from controller method.
