README

The LswApiCallerBundle adds a CURL API caller to your Symfony2 application. It is easy to use from the code and is aimed to have full debugging capabilities.

Read the LeaseWebLabs blog about LswApiCallerBundle

Requirements

PHP 5.3 with curl support
Symfony 2.1 (works under Symfony 2.0 as well)

Installation

Installation is broken down in the following steps:

Download LswApiCallerBundle using composer
Enable the Bundle
Make sure the cURL module in PHP is enabled

Step 1: Download LswApiCallerBundle using composer

Add LswApiCallerBundle in your composer.json:

{
    "require": {
        "leaseweb/api-caller-bundle": "*",
        ...
    }
}

Now tell composer to download the bundle by running the command:

$ php composer.phar update leaseweb/api-caller-bundle

Composer will install the bundle to your project's vendor/leaseweb directory.

Step 2: Enable the bundle

Enable the bundle in the kernel:

<?php
// app/AppKernel.php

public function registerBundles()
{
    $bundles = array(
        // ...
        new Lsw\ApiCallerBundle\LswApiCallerBundle(),
    );
}

Step 3: Make sure the cURL module in PHP is enabled

On a Debian based distribution (like Ubuntu) the package is called "php5-curl" and can be installed using the following commands:

$ sudo apt-get install php5-curl
$ sudo service apache2 restart

On a RedHat based distribution (like CentOS) the package is called "php-curl" and can be installed using the following commands:

$ sudo yum install php-curl
$ sudo service httpd restart

To check this create and run a PHP file with the following contents:

<?php phpinfo() ?>

It should display that the option "cURL support" is set to "enabled".

This package should work on a Windows installation as well provided the CURL support is enabled in PHP.

Usage

You can use the caller by getting the service "api_caller" and using the "call" function with one of the available call types:

HttpGetJson
HttpPostJson
HttpPutJson
HttpDeleteJson
HttpGetHtml

Example of usage with the "HttpGetJson" call type:

use Symfony\Bundle\FrameworkBundle\Controller\Controller
use Lsw\ApiCallerBundle\Call\HttpGetJson;

class SomeController extends Controller
{
    public function someAction()
    {
        ...
        $output = $this->get('api_caller')->call(new HttpGetJson($url, $parameters));
        
        $entities = $output[0];
        $httpCode = $output[1];
        ...
    }
}

Configuration

By default it uses these cURL options:

parameters:
    api_caller.options:
        timeout: 10  # maximum transport + execution duration of the call in sec.
        ssl_verifypeer: false  # to stop cURL from verifying the peer's certificate.
        useragent: "LeaseWeb API Caller"  # contents of the "User-Agent: " header.
        followlocation: true  # to follow any "Location: " header that the server sends.
        sslversion: 3  # set to 3 to avoid any bugs that relate to automatic version selection.
        fresh_connect: false  # set to true to force full reconnect every call.
