vperyod.accept-handler

Aura\Accept Content Negotiation Middleware

Installation

composer require vperyod/accept-handler

Usage

See Aura\Accept documentation.

// Create handler
$handler = new Vperyod\AcceptHandler\AcceptHandler();

// Optionally set the attribute on which to store the `Accept` object
// Defaults to 'aura/accept:accept'
$handler->setAcceptAttribute('accept');

// Add to your middleware stack, radar, relay, etc.
$stack->middleware($handler);

// Subsequent dealings with `Request` will have the `Accept` instance available
// at the previous specified atribute
$accept = $request->getAttribute('accept');


// The `AcceptRequestAwareTrait` should make dealings easier.
//
// Have all your objects that deal with the accept attribute on the request use
// the `AcceptRequestAwareTrait` and have your DI container use the setter, so that 
// they all know where the Accept object is stored.
//
// Additionally, the trait supplies negotiate methods to eaily access the the
// `Accept` Negotiation methods.
