Http request

A minimalistic http/curl request interface that was part of the Semantic MediaWiki code base and is now being deployed as independent library.

This library provides:

• HttpRequest interface
• CurlRequest as cURL implementation of the HttpRequest
• CachedCurlRequest to support low-level caching on repeated CurlRequest requests
• MultiCurlRequest to make use of the cURL multi stack feature
• SocketRequest to create asynchronous socket connections

Requirements

• PHP 5.3 or later

Installation

The recommended installation method for this library is by adding the dependency to your composer.json.

{
	"require": {
		"onoi/http-request": "~1.3"
	}
}

Usage

use Onoi\HttpRequest\CurlRequest;
use Onoi\HttpRequest\Exception\BadHttpResponseException;
use Onoi\HttpRequest\Exception\HttpConnectionException;

class Foo {

	private $curlRequest = null;

	public function __constructor( CurlRequest $curlRequest ) {
		$this->curlRequest = $curlRequest;
	}

	public function doMakeHttpRequestTo( $url ) {

		$this->curlRequest->setOption( CURLOPT_URL, $url );

		if ( !$this->curlRequest->ping() ) {
			throw new HttpConnectionException( "Couldn't connect" );
		}

		$this->curlRequest->setOption( CURLOPT_RETURNTRANSFER, true );

		$this->curlRequest->setOption( CURLOPT_HTTPHEADER, array(
			'Accept: application/x-turtle'
		) );

		$response = $this->curlRequest->execute();

		if ( $this->curlRequest->getLastErrorCode() == 0 ) {
			return $response;
		}

		throw new BadHttpResponseException( $this->curlRequest );
	}
}

$httpRequestFactory = new HttpRequestFactory();

$instance = new Foo( $httpRequestFactory->newCurlRequest() );
$response = $instance->doMakeHttpRequestTo( 'http://example.org' );

OR

$cacheFactory = new CacheFactory();

$compositeCache = $cacheFactory->newCompositeCache( array(
	$cacheFactory->newFixedInMemoryLruCache( 500 ),
	$cacheFactory->newDoctrineCache( new \Doctrine\Common\Cache\RedisCache() )
) );

$httpRequestFactory = new HttpRequestFactory( $compositeCache );
$cachedCurlRequest = $httpRequestFactory->newCachedCurlRequest();

// Responses for a request with the same signature (== same endpoint and same query
// content) will be cached if the request was successful for a specified 1 h (3600 sec)
$cachedCurlRequest->setOption( ONOI_HTTP_REQUEST_RESPONSECACHE_TTL, 60 * 60 );

$instance = new Foo( $cachedCurlRequest );
$response = $instance->doMakeHttpRequestTo( 'http://example.org' );
