Http request

, _(*1)

A minimalistic http/curl request interface that was part of the Semantic MediaWiki code base and is now being deployed as independent library., _(*2)

This library provides:, _(*3)

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., _(*4)

{
    "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' );
