Guzzle Bundle Cache Plugin

This plugin integrates cache functionality into Guzzle Bundle, a bundle for building RESTful web service clients.

Requirements

• PHP 7.0 or above
• Guzzle Bundle
• Guzzle Cache middleware

Installation

Using composer:

composer.json

{
    "require": {
        "gregurco/guzzle-bundle-cache-plugin": "dev-master"
    }
}

command line

$ composer require gregurco/guzzle-bundle-cache-plugin

Usage

Enable bundle

Symfony 2.x and 3.x

Plugin will be activated/connected through bundle constructor in app/AppKernel.php, like this:

new EightPoints\Bundle\GuzzleBundle\EightPointsGuzzleBundle([
    new Gregurco\Bundle\GuzzleBundleCachePlugin\GuzzleBundleCachePlugin(),
])

Symfony 4

The registration of bundles was changed in Symfony 4 and now you have to change src/Kernel.php to achieve the same functionality.
Find next lines:

foreach ($contents as $class => $envs) {
    if (isset($envs['all']) || isset($envs[$this->environment])) {
        yield new $class();
    }
}

and replace them by:

foreach ($contents as $class => $envs) {
    if (isset($envs['all']) || isset($envs[$this->environment])) {
        if ($class === \EightPoints\Bundle\GuzzleBundle\EightPointsGuzzleBundle::class) {
            yield new $class([
                new \Gregurco\Bundle\GuzzleBundleCachePlugin\GuzzleBundleCachePlugin(),
            ]);
        } else {
            yield new $class();
        }
    }
}

Basic configuration

# app/config/config.yml

eight_points_guzzle:
    clients:
        api_payment:
            base_url: "http://api.domain.tld"

            # define headers, options

            # plugin settings
            plugin:
                cache:
                    enabled: true

Configuration with specific cache strategy

# app/config/services.yml

services:
    acme.filesystem_cache:
        class: Doctrine\Common\Cache\FilesystemCache
        arguments: ['/tmp/']
        public: false

    acme.doctrine_cache_storage:
        class: Kevinrob\GuzzleCache\Storage\DoctrineCacheStorage
        arguments: ['@acme.filesystem_cache']
        public: false

    acme.private_cache_strategy:
        class: Kevinrob\GuzzleCache\Strategy\PrivateCacheStrategy
        arguments: ['@acme.doctrine_cache_storage']
        public: false

# app/config/config.yml

eight_points_guzzle:
    clients:
        api_payment:
            plugin:
                cache:
                    enabled: true
                    strategy: "acme.private_cache_strategy"

Invalidate cache

# get client
$apiPaymentClient = $this->get('eight_points_guzzle.client.api_payment');

# do a request
$apiPaymentClient->request('GET', 'ping');

# invalidate cache
$event = new InvalidateRequestEvent($apiPaymentClient, 'GET', 'ping');
$this->get('event_dispatcher')->dispatch(GuzzleBundleCacheEvents::INVALIDATE, $event);
