Dynamic Headers about retrofit-php

[natebrunette]

Is it possible to use the event system for this?

[mloberg]

That solves the issue.

Can someone please provide an example? @natebrunette @mloberg

@MDXDave If you're using Guzzle, you would use the event system (v5) or middleware (v6) to modify the request directly. Check out the Guzzle docs.

See @natebrunette comment below. We ended up using Retrofit's event system because we didn't have to worry about what version of Guzzle we were using.

@MDXDave I really need to update the docs, but you can also use the event system. Set a Symfony event dispatcher to the builder, then add a subscriber that listens for retrofit.beforeSend. You'll receive a PSR-7 request object on the event. Modify it, then set the new request object (because it's immutable) back to the event.

Thanks for your answers. And yes, the docs are not completely 😼

Working solution for others with the same problem below.

$dispatcher = new EventDispatcher();
$dispatcher->addListener('retrofit.beforeSend', function (BeforeSendEvent $event) use(&$accessToken) {
      $request = $event->getRequest()->withAddedHeader("Authorization", "Bearer ".$accessToken);
      $event->setRequest($request);
});

return RestAdapter::builder()->setEventDispatcher($dispatcher)->setBaseUrl(....)->build()->create(...::class);
