Content negotiation middleware for snicco/http-routing

A middleware that uses middlewares/negotiation with some sensible defaults.

It will determine the best content-type and content-language based on the provided Accept headers and will update the Accept header of the request accordingly so that it only contains one content-type/content-language.

If no matching content type can be determined a 406 HTTPException is thrown.

Installation

composer require snicco/content-negotiation-middleware

Usage

This middleware should be added globally in the MiddlewareResolver.

It must be bound in the PSR-11 container that the snicco/http-routing component uses.

// In your container definitions
use Snicco\Middleware\Negotiation\NegotiateContent;

// basic configuration based on defaults.
$negotiation = new NegotiateContent(
   ['en'] // content languages
);

// With custom configuration for content-types your application can provide (sorted by priority)
$negotiation = new NegotiateContent(
   ['en'],
   [ 
       'html' => [
                'extension' => ['html', 'php'],
                'mime-type' => ['text/html'],
                'charset' => true,
            ],
       'txt' => [
                'extension' => ['txt'],
                'mime-type' => ['text/plain'],
                'charset' => true,
            ],
       'json' => [
                'extension' => ['json'],
                'mime-type' => ['application/json'],
                'charset' => true,
            ],
   ] 
);
