Message Headers

Ecotone provides easy way to pass Message Headers with your Message and use it in your Message Handlers or Interceptors.
In case of asynchronous scenarios, Message Headers will be automatically mapped and passed to your Message Broker.
Passing headers to Bus:
Pass your metadata (headers), as second parameter.
$this->commandBus->send(
   new CloseTicketCommand($request->get("ticketId")),
   ["executorUsername" => $security->getUser()->getUsername()]
);
Then you may access them directly in Message Handlers:
#[CommandHandler]
public function closeTicket(
      CloseTicketCommand $command, 
      #[Header("executorUsername")] string $executor
) {
//        handle closing ticket
}  
If you have defined Converter for given type, then you may type hint for the object and Ecotone will do the conversion:
#[CommandHandler]
public function closeTicket(
      CloseTicketCommand $command, 
      #[Header("executorUsername")] Username $executor
) {
//        handle closing ticket
}
