README

The Route Middleware package contains two middleware: Phapi\Middleware\Route\Route and Phapi\Middleware\Route\Dispatch that handles routing and dispatch to endpoints.

The Route Middleware will invoke the first route that matches the current HTTP request’s URI and method. If the request URI doesn't match any defined route a 404 Not Found will be returned to the client. If the request method isn't implemented a 405 Method Not Allowed will be returned instead.

The router does three things to be able to find a match, first it tries to find a direct match. This is possible for routes that doesn't contain regular expressions. If no direct match can be found the router will look in it's cache for a match. As a last resort the router tries to match against the routes that contains regular expressions. If a match is found it will be added to the cache.

Installation

This middleware is by default included in the Phapi Framework but if you need to install it it's available to install via Packagist and Composer.

$ php composer.phar require phapi/middleware-route:1.*

Configuration

The configuration contains three steps:

• Create middleware objects
• Define routes
• Add to pipeline

Create middleware objects

<?php

use Phapi\Middleware\Route\Route;
use Phapi\Middleware\Route\Router;
use Phapi\Middleware\Route\RouteParser;
use Phapi\Middleware\Route\Dispatch;

// Use the dependency injection container to get the configured cache
$route = new Route(new Router(new RouteParser, $container['cache']));

Define routes

Routes can be added by passing an array (with the route as the key and the name of the resource as the value) to the addRoutes function.

<?php

// Create a list of routes
$routes = [
  '/users'                  => '\\Phapi\\Endpoint\\Users',
  '/users/{name:a}'         => '\\Phapi\\Endpoint\\User',
  '/articles/{id:[0-9]+}'   => '\\Phapi\\Endpoint\\Article',
  '/blog/{slug}/{title:c}?' => '\\Phapi\\Endpoint\\Blog\\Post',
];

$route->addRoutes($routes);

By default a route pattern syntax is used where {foo} specified a placeholder with name foo and matching the string [^/]+. To adjust the pattern the placeholder matches, you can specify a custom pattern by writing {bar:[0-9]+}.

Regex Shortcuts

:i => :/d+                # numbers only
:a => :[a-zA-Z0-9]+       # alphanumeric
:c => :[a-zA-Z0-9+_-\.]+  # alnumnumeric and +-_. characters
:h => :[a-fA-F0-9]+       # hex

Get params in an Endpoint

The router will inject the params in to the called method on the Endpoint. Lets use this route as an example:

<?php
$routes = [
  '/users/{name:a}'         => '\\Phapi\\Endpoint\\User',
];

If we want to get the name value from /users/phapi we need to specify an endpoint looking like this:

<?php

class User extends Endpoint {

  public function get($name) // $name will contain 'phapi'
  {
    ...
  }
}

Add to pipeline

Last but not least, add the middleware to the pipeline. The Dispatcher doesn't need any configuration.

<?php
$pipeline->pipe($route);
$pipeline->pipe(new \Phapi\Middleware\Route\Dispatcher());

Complete example

<?php

use Phapi\Middleware\Route\Route;
use Phapi\Middleware\Route\Router;
use Phapi\Middleware\Route\RouteParser;
use Phapi\Middleware\Route\Dispatch;

// Use the dependency injection container to get the configured cache
$route = new Route(new Router(new RouteParser, $container['cache']));

// Create a list of routes
$routes = [
  '/users'                  => '\\Phapi\\Endpoint\\Users',
  '/users/{name:a}'         => '\\Phapi\\Endpoint\\User',
  '/articles/{id:[0-9]+}'   => '\\Phapi\\Endpoint\\Article',
  '/blog/{slug}/{title:c}?' => '\\Phapi\\Endpoint\\Blog\\Post',
];

$route->addRoutes($routes);

$pipeline->pipe($route);
$pipeline->pipe(new \Phapi\Middleware\Route\Dispatcher());

See the configuration documentation for more information about how to configure the integration with the Phapi Framework.
