how do i get request token by dispatcher

[itknight]

i wanna build jwt auth in my application (modules ,not micro) , as the documentation events.md said .
i use dispatcher:beforeRouteExecuted to do my job.

$eventsManager->attach("dispatch:beforeExecuteRoute", function ($event, $dispatcher) {
        var_dump(get_class_methods(get_class($dispatcher)));
        var_dump($dispatcher);
        //controller or action doesn't exist
   
    });

as there is only one parameter $dispatcher,
how could i get headers infomation by $dispatcher
Wish best regards

my bad ,i've worked it out.

<?php

$request = $dispatcher->getDI()->getShared("request");

$request->getHeader();
...

with this , i can get anythin' I want.
