📂 About

License Server package, which is a Laravel package that allows you to manage your Laravel applications license. You can use it with any product or service. License Server comes with the agnostic license management system, which allows you to manage your licenses in a simple and easy way. Just add license relation to any product model then you can work in your logic.

This package requires license-connector package. License Connector is client implementation for License Server. Package for the client makes a request to License Server and gets a response.

# publish configs
php artisan vendor:publish --tag=license-server-configs

🗝️ Model Relations

Every license must-have product, because we need to know what it is licensed for. The client application will send this information to the License Server. Then we can check if the license is valid for given the product.

Product model can be any model that you want to be licensed. Add Licensable trait to your product model.

<?php

namespace App\Models;

use Illuminate\Database\Eloquent\Model;
use Illuminate\Database\Eloquent\Factories\HasFactory;

use LaravelReady\LicenseServer\Traits\Licensable;

class Product extends Model
{
    use HasFactory, Licensable;

    protected $table = 'products';

    protected $fillable = [
        'name',
        'description',
        'price',
        'image',
        ...
    ];

    ...
}

📌 Service Methods

Add in your namespace list:

use LaravelReady\LicenseServer\Services\LicenseService;

and product model

use App\Models\Product;

addLicense

First, we need to know licensing models. This package supports two types of licensing models: to Domain and to User. Both of them are valid. If you want to add license to domain, you must pass domain parameter. If you want to add license to user, you must pass userId parameter. Also, when you pass both of them, you will get domain license.

// get licensable product
$product = Product::find(1);
$user = User::find(1);

// add license to domain
$license = LicenseService::addLicense($product, 'example.com', $user->id);

// add license to user
$license = LicenseService::addLicense($product, null, $user->id);

// with expiration in days (see configs for defaults)
$license = LicenseService::addLicense($product, null, $user->id, 999);

// with lifetime license (see configs for defaults)
$license = LicenseService::addLicense($product, null, $user->id, null, true);

// with trial license (see configs for defaults)
$license = LicenseService::addLicense($product, null, $user->id, null, false, true);

If you provide domain, then the license will be added to the domain. If you don't provide domain, then the license will be added to the user (in this case user id is required.).
Other parameters are optional and do not forget to configure configs.
This method returns LaravelReady\LicenseServer\Models\License model.
All license keys are in UUID format.

getLicenseBy*

getLicenseByKey: get license by license key.
- LicenseService::getLicenseByKey(string $licenseKey)
getLicenseByUserId: get license by user id and license key.
- LicenseService::getLicenseByUserId(int $userId, string $licenseKey = null)
getLicenseByDomain: get license by domain and license key.
- LicenseService::getLicenseByDomain(string $domain, string $licenseKey = null)

checkLicenseStatus

// license key in uuid format
$licenseKey = "46fad906-bc51-435f-9929-db46cb4baf13";

// check license status
$licenseStatus = LicenseService::checkLicenseStatus($licenseKey);

Returns "active", "inactive", "suspended", "expired", "invalid-license-key" and "no-license-found".

setLicenseStatus

// license key in uuid format
$licenseKey = "46fad906-bc51-435f-9929-db46cb4baf13";

// check license status
$licenseStatus = LicenseService::setLicenseStatus($licenseKey, "suspended");

You can only set active, inactive, suspended status.

🛠️ Custom Controller

If you want to use own license validation controller you can integrate it easily.

Click to see the example!

<?php

namespace App\Http\Controllers;

use Illuminate\Http\Request;
use Illuminate\Support\Facades\Event;

use LaravelReady\LicenseServer\Models\License;
use LaravelReady\LicenseServer\Events\LicenseChecked;

class LicenseController extends Controller
{
    /**
     * Custom license validation
     *
     * @param Request $request
     * @param License $license
     *
     * @return \Illuminate\Http\JsonResponse
     */
    public function licenseValidate(Request $request, License $license)
    {
        // this controller is works under 'auth:sanctum' and 'ls-license-guard' middleware
        // in this case 'auth()->user()' will be is our license

        $_license = $license->select(
            'domain',
            'license_key',
            'status',
            'expiration_date',
            'is_trial',
            'is_lifetime'
        )->where([
            ['id', '=', auth()->user()->id],
            ['is_trial', '!=', true]
        ])->first();

        $data = $request->input();

        // event will be fired after license is checked
        // this part depends to your logic, you can remove it or change it
        Event::dispatch(new LicenseChecked($_license, $data));

        $_license->appent_some_data = 'some data and date now -> ' . now();

        return $_license;
    }
}

Then you need to register this custom controller in your config/license-server.php file.

Click to see the example!

/**
 * Custom controllers for License Server
 */
'controllers' => [
    /**
     * License validation controller
     *
     * You can use this controller to handle license validating
     *
     * See the documentation for more information.
     *
     */
    'license_validation' => [
        App\Http\Controllers\LicenseController::class,
        'licenseValidate'
    ]
]

🪢 Events

🪡 LicenseChecked Event

You can send custom data with connector and on the license server-side, you can catch this custom data. First you need to create a listener for this event.

php artisan make:listener LicenseCheckedListener --event=LicenseChecked

Add class LicenseChecked with LaravelReady\LicenseServer\Events\LicenseChecked namespace. You can retrieve custom data from event.

<?php

namespace App\Listeners;

use LaravelReady\LicenseServer\Events\LicenseChecked;

class LicenseCheckedListener
{
    public function __construct()
    {
        //
    }

    public function handle(LicenseChecked $event)
    {
        // $event->license,
        // $event->data,
    }
}

Finally, you need to register this listener in your config/license-server.php file.

Click to see the example!

/**
    * Event listeners for License Server
    */
'event_listeners' => [
    /**
        * License checked event listener
        *
        * You can use this event to do something when a license is checked.
        * Also you can handle custom data with this listener.
        *
        * See the documentation for more information.
        *
        * Default: null
        */
    'license_checked' => App\Listeners\LicenseCheckedListener::class,
],

Ready to Use API

Ready to use API is included with simple resource methods. API endpoint is /api/license-server/licenses.

Domain Validation

License Server uses a cache to store the public tld list. See tld list at https://data.iana.org/TLD/tlds-alpha-by-domain.txt

The TLD list cache is will be stored at the storage/license-server/iana-tld-list.txt file and do not edit this file.

In development you may use domain like example.test etc. but you won't pass domain validation because the test is not valid tld.

⚠️ Warnings

This package is under active development and is not yet stable. There may be some changes in later versions.
Don't forget this package just provides management of licenses and product/customer communication.
Please don't confuse it with ioncube or similar source code encryption tools.
