README

A client class in PHP for use with the BooXtream webservice.

• Has the ability to upload an epub file to the BooXtream webservice
• Alternatively specify an epub file stored on the BooXtream storage servers
• Can return an epub file, a (converted) mobi file or an xml containing one or more downloadlinks

Installing via Composer

BooXtreamClient is available in Packagist, just add it to your composer.json

composer require icontact/booxtreamclient

or

{
    "require": {
        "icontact/booxtreamclient": "~2.0"
    }
}

Alternatively you can just download the package and run composer install to get the requirements.

The only requirements at the moment are PHP 7.2.5 and up and Guzzle.

If you do not wish to use Composer you will need to fulfill the dependencies on your own.

Usage

You will need:

• a username and API key for the service
• an array of options (refer to the BooXtream web service API documentation)
• an epub file or a file stored on the BooXtream service

The type parameter can be either 'epub', 'mobi' or 'xml'. In the first two cases a file will be returned by the service, in the case of 'xml' you will receive one or two downloadlinks, depending on your settings (aka delivery platform).

require('vendor/autoload.php');

use \Icontact\BooXtreamClient\BooXtreamClient;
use \Icontact\BooXtreamClient\Options;
use \GuzzleHttp\Client;

// a guzzle client
$guzzle = new Client();

// an options object, refer to the documentation for more information on the options
$options = new Options([
    'customername' => 'Foo Bar',
    'referenceid' => 'bazdibzimgir12345',
    'languagecode' => 1033
]);

// create the BooXtream Client
$type = 'xml'; // returns downloadlinks
$credentials = ['username', 'apikey']; // you will need a username and an API key
$BooXtream = new BooXtreamClient($type, $options, $credentials, $guzzle);

We're now going to send the request.

// add a file location to the epub file you want to watermark
$BooXtream->setEpubFile('/path/to/your/file.epub');

// and send
$Response = $BooXtream->send();

A request with a stored file is slightly different. Instead of adding an epubfile you just need to provide the name of the file (with or without .epub extension):

$BooXtream->setStoredEpubFile('filename');

Options

The available options are as follows. Refer to the API Documentation for details:

required:

• customername (string)
• customeremailaddress (string)
• referenceid (string)
• languagecode (int)

additionaly required if using xml (aka delivery platform):

• expirydays (int)
• downloadlimit (int)

optional:

• exlibrisfont (string), this should contain either 'sans', 'serif' or 'script'
• exlibris (bool), default: false
• chapterfooter (bool), default: false
• disclaimer (bool), default: false
• showdate (bool), default: false

optional if using xml (aka delivery platform):

• epub (bool), default: true
• kf8mobi (bool), default: false

custom ex libris

It is also possible to set a custom ex libris file according to the specifications in the API Documentation.

$BooXtream->setExlibrisFile('filename');

Response

The BooXtreamClient returns an object of the type of GuzzleHttp\Psr7\Response

The response always contains a statuscode ($Response->getStatusCode();). If the request was successful this will be 200. Any other status code is an error and will throw an Exception of the type of GuzzleHttp\Exception\ClientException. You can retrieve a Response object as follows:

try {
  $Response = $BooXtream->send();
} catch (ClientException $e) {
  $Response = $e->getResponse();
}

Check the HTTP Reason ($Response->getReasonPhrase();) for more information.

Epub/Mobi

If you requested an epub or mobi file this can be accessed by reading the body ($Response->getBody();). The body is a stream, refer to the PHP Documentation for more information on how to access it. Furthermore you can access the file's content-type with $Response->getHeader('content-type');.

XML or error

If you requested xml (aka delivery platform) or if an error occurred more information can be found by accessing the body ($Response->getBody();). The body is a stream, refer to the PHP Documentation for more information on how to access it.

The XML looks like this:

• Request, containing information about the request you made (options, etc)
• Response, containing either a set of downloadlinks or more information on an error
