README

LibKeyClient is a PHP library for querying the LibKey Article DOI lookup API from Third Iron.

Installation

Use the package manager composer to install LibKeyClient.

composer require bclibraries/libkey-client:^0.1

LibKeyClient is currently a 0.* release, so things will change drastically with any minor release.

Usage

use BCLib\LibKeyClient\LibKeyClient;

require_once __DIR__ . '/vendor/autoload.php';

// LibKey API identifiers.
$libkey_apikey = 'xxxxxxxx-xxxx-xxxx-xxxx-xxxxxxxxxxxx';
$libkey_id = 'xxx';
$doi = '10.1371/journal.pone.0193984';

$libkey = LibKeyClient::build($libkey_id, $libkey_apikey);

// Send request.
$http_response = $libkey->request($doi);

// Parse
if ($libkey_response = $libkey->parse($http_response)) {
    echo "Fulltext for {$libkey_response->getTitle()} is at {$libkey_response->getFullTextFile()}\n";
} else {
    echo "Could not find LibKey entry for '$doi'\n";
}

The HTTPClient

LibKey client uses the Symfony HTTPClient component to handle HTTP requests. The Symfony client was chosen instead of a PSR-18—compliant implementation because the original use case required concurrent requests, which PSR-18 does not support.

Running tests

PHPUnit is used for testing. You may need to enable the sockets extension.

./vendor/bin/phpunit
