ApiCacher Bundle

ApiCacher is a symfony2 caching system for data provided by API endpoints. It is used for optimising the performance of a website that uses external API services for data.

Installation

Composer:

"require": {
        "h-space/api-cacher-bundle": "dev-master"
    }

$ composer install

Usage

Include the library:

    use HSpace\Bundle\ApiCacherBundle\Library\ApiCacher;

Initialize class:

     $cacher = new ApiCacher();

Single request:

     $url = 'https://example.com/api/endpoint?api_key=YOUR_API_KEY'; 
     $fields = null; // if post request, fields is an array with post data else null
     $json_decode = true;
     $rebuild_cache = true; // rebuild cache at the the end of the proccess, more details below
     $response = $cacher->request($url,$fields,$json_decode,$rebuild_cache);

Multi Requests:

     $url_one = 'https://example.com/api/endpoint?api_key=YOUR_API_KEY'; 
     $url_two = 'https://example.com/api/endpoint_two?api_key=YOUR_API_KEY'; 
     $fields = null; // if post request, fields is an array with post data else null
     $json_decode = true;
     $rebuild_cache = true; // rebuild cache at the the end of the proccess, more details below
     $cacher->request_multi($url_one,$fields,$json_decode,$rebuild_cache);
     $cacher->request_multi($url_two,$fields,$json_decode,$rebuild_cache);
     $cacher->execute($json_decode);
     $responses = $cacher->multi_output();
 
 //Accessing the responses
    $url_one_response = $responses[$url_one];
    $url_two_response = $responses[$url_two];
