Sandbox

Working example can be found at devhelp/piwik-silex-provider-sandbox

Purpose

Provides integration of Piwik API into Silex. Adds services to the dependency injection container that allows to use Piwik API methods as services. It uses devhelp/piwik-api library - check its documentation for more advanced usage.

Usage

Register the provider

$app = new Silex\Application();

$app->register(new Devhelp\Silex\Piwik\PiwikApiServiceProvider(array(
    'client' => 'my_piwik.client',
    'api' => array(
        'reader' => array(
            'url' => 'http://my_piwik_instance.piwik.pro',
            'default_params' => array(
                'token_auth' => 'piwik_token_auth',
                'idSite' => 123
            )
        )
    )
)));

Create piwik client service that was set as 'client'

This example uses PiwikGuzzleClient class that is responsible for making http request to Piwik. You can include this extension by including devhelp/piwik-api-guzzle in your project

//'guzzle' service must implement GuzzleHttp\ClientInterface
$app['my_piwik.client'] = $app->share(function () use ($app) {
    return new Devhelp\Piwik\Api\Guzzle\Client\PiwikGuzzleClient($app['guzzle']));
});

Use API method in your use case

add service to the container

$app['my_service'] = $app->share(function () use ($app) {
    return new Acme\DemoBundle\Service\MyService($app['devhelp_piwik.api']);
});

example service definition

namespace Acme\DemoBundle\Service;


use Devhelp\Piwik\Api\Api;

class MyService
{

    /**
     * @var Api
     */
    private $piwikApi;

    public function __construct(Api $piwikApi)
    {
        $this->piwikApi = $piwikApi;
    }

    public function doSomething()
    {
        //...
        $this->piwikApi->getMethod('PiwikPlugin.pluginAction')->call();
        //...
    }
}

Define API parameters resolved at runtime

You are allowed to set services as a params. If you do that then the service will be used to resolve the parameter at runtime. For example have a service that would return token_auth of logged in user

$app = new Silex\Application();

$app->register(new Devhelp\Silex\Piwik\PiwikApiServiceProvider(array(
    'client' => 'my_piwik.client',
    'api' => array(
        'reader' => array(
            'url' => 'http://my_piwik_instance.piwik.pro',
            'default_params' => array(
                'token_auth' => 'my_token_auth_provider',
                'idSite' => 123
            )
        )
    )
)));

my_token_auth_provider service definition (assumes that SecurityServiceProvider is registered)

$app['my_token_auth_provider'] = $app->share(function () use ($app) {
    return new Acme\DemoBundle\Param\MyTokenAuthProvider($app['security.token_storage']);
});

MyTokenAuthProvider class definition (assumes that User class has getPiwikToken method)

namespace Acme\DemoBundle\Param;

use Devhelp\Piwik\Api\Param\Param;
use Symfony\Component\Security\Core\Authentication\Token\Storage\TokenStorageInterface;
use Symfony\Component\Security\Core\Authentication\Token\TokenInterface;

class MyTokenAuthProvider implements Param
{

    /**
     * @var TokenStorageInterface
     */
    private $tokenStorage;

    public function __construct(TokenStorageInterface $tokenStorage)
    {
        $this->tokenStorage = $tokenStorage;
    }

    public function value()
    {
        $token = $this->tokenStorage->getToken();

        return $token instanceof TokenInterface ? $token->getUser()->getPiwikToken() : null;
    }
}

Define API methods as services

$app['my_piwik_method'] = $app->share(function () use ($app) {
    return $app['devhelp_piwik.api']->getMethod('VisitFrequency.get');
});
