ZF3：如何根据方法和路由路由到特定的控制器/动作？

Question

In my module's module.config.php , I have something like this:

namespace Application;

return [
    //...
    // myroute1 will route to IndexController fooAction if the route is matching '/index/foo' but regardless of request method
    'myroute1' => [
        'type' => Zend\Router\Http\Literal::class,
        'options' => [
            'route'    => '/index/foo',
            'defaults' => [
                'controller' => Controller\IndexController::class,
                'action'     => 'foo',
            ],
        ],
    ],

    // myroute2 will route to IndexController fooAction if the route is request method is GET but regardless of requested route
    'myroute2' => [
        'type'    => Zend\Router\Http\Method::class,
        'options' => [
            'verb'     => 'get',
            'defaults' => [
                'controller'    => Controller\IndexController::class,
                'action'        => 'foo',
            ],
        ],
    ],
    //...
];

What I'm trying to achieve:

• If route /index/foo is requested AND is requested by GET method, then it should be routed to IndexController fooAction
• If route /index/foo is requested AND is requested by POST method, then it should be routed to IndexController bar Action (notice it's barAction here not fooAction)

How to achieve that?

Answer 1

Try changing the literal to a Zend\\Mvc\\Router\\Http\\Part route, and then putting the HTTP routes in as CHILD routes!

See here https://docs.zendframework.com/zend-router/routing/#http-route-types

Answer 2

A note to myself and anyone else looking, as additional note to @delboy1978uk's answer.

The answer I was looking for is something like this:

• GET /index/foo => IndexController fooAction
• POST /index/foo => IndexController barAction

So the code in module.config.php file can be like this:

return [
    //...
    'myroute1' => [// The parent route will match the route "/index/foo"
        'type' => Zend\Router\Http\Literal::class,
        'options' => [
            'route'    => '/index/foo',
            'defaults' => [
                'controller' => Controller\IndexController::class,
                'action'     => 'foo',
            ],
        ],
        'may_terminate' => false,
        'child_routes' => [
            'myroute1get' => [// This child route will match GET request
                'type' => Method::class,
                'options' => [
                    'verb' => 'get',
                    'defaults' => [
                        'controller' => Controller\IndexController::class,
                        'action'     => 'foo'
                    ],
                ],
            ],
            'myroute1post' => [// This child route will match POST request
                'type' => Method::class,
                'options' => [
                    'verb' => 'post',
                    'defaults' => [
                        'controller' => Controller\IndexController::class,
                        'action'     => 'bar'
                    ],
                ],
            ]
        ],
    ],
    //...
];

I know this is an old topic but I wanted to share my answer for anyone who comes across this and is struggling with zend or Laminas (I use Laminas) and the routing of method based AND localized routes. Basically you should be able to just replace "Laminas" by "Zend" for the namespaces. The code base is very similar.

First of all: I was not able to use @evilReiko's solution because 'may_terminate' => false, always threw an exception for me. When I set it to true the child routes were ignored ... obviously :D

But the note helped me to understand some stuff going on. I decided to just implement a custom class which handles both: URL localization and method/action routing.

I created a new folder Classes and added a new file MethodSegment into modules/Application . So the file path would be modules/Application/Classes/MethodSegment.php .

<?php

namespace Application\Classes;

use Laminas\Router\Exception;
use Laminas\Stdlib\ArrayUtils;
use Laminas\Stdlib\RequestInterface as Request;
use Laminas\Router\Http\RouteMatch;
use Traversable;
    
/**
 * Method route.
 */
class MethodSegment extends \Laminas\Router\Http\Segment
{
    /**
     * associative array [method => action]
     *
     * @var array
     */
    protected $methodActions;

    /**
     * Default values - accessing $defaults from parent class Segment
     *
     * @var array
     */
    protected $defaults;

    /**
     * Create a new method route
     *
     * @param  string $route
     * @param  array  $constraints
     * @param  array  $defaults
     */
    public function __construct($route, array $constraints = [], array $defaults = [])
    {
        if(is_array($defaults['action']))
        {
            $this->methodActions = $defaults['action'];
            $defaults['action'] = array_values($defaults['action'])[0];
        }

        parent::__construct($route, $constraints, $defaults);
    }

    /**
     * factory(): defined by RouteInterface interface.
     *
     * @see    \Laminas\Router\RouteInterface::factory()
     *
     * @param  array|Traversable $options
     * @return Method
     * @throws Exception\InvalidArgumentException
     */
    public static function factory($options = [])
    {
        if ($options instanceof Traversable) {
            $options = ArrayUtils::iteratorToArray($options);
        } elseif (! is_array($options)) {
            throw new Exception\InvalidArgumentException(sprintf(
                '%s expects an array or Traversable set of options',
                __METHOD__
            ));
        }

        if (! isset($options['defaults'])) {
            $options['defaults'] = [];
        }

        return new static($options['route'] ?? null, $options['constraints'] ?? [], $options['defaults']);
    }

    /**
     * match(): defined by RouteInterface interface.
     *
     * @see    \Laminas\Router\RouteInterface::match()
     *
     * @return RouteMatch|null
     */
    public function match(Request $request, $pathOffset = null, array $options = [])
    {
        if (! method_exists($request, 'getMethod')) {
            return null;
        }

        $requestVerb = strtolower($request->getMethod());
        $verb = array_keys($this->methodActions);

        if (in_array($requestVerb, $verb)) {
            $this->defaults['action'] = $this->methodActions[$requestVerb];
            return parent::match($request, $pathOffset, $options);
        }

        return null;
    }
}

Basically I copied the code from the Laminas Method class and enhanced it so I can pass an array of actions.

You can use the MethodSegment like so:

use App\Routing\MethodSegment;
return [
    'router' => [
        'routes' => [
            'home' => [
                'type'    => MethodSegment::class,
                'options' => [
                    'route'    => /[:language/],
                    'constraints' => [...],
                    'defaults' => [
                        'controller' => Controller\IndexController::class,
                        'action'     => [
                            'get' => 'index',
                            'post' => 'postIndex', // e.g. form
                        ],
                    ],
                ],
            ],
      [...]

Hope this helps anyone, IMO the child route approach is very clunky.
