Multi Agent Library

A php package that enable the user to handle multiple agent (devices) at the same time. This package allows you to link any model with many devices, and provide a kind of authentication for the functionality this device can use.

Installation

Install using composer:

composer require aldeebhasan/multi-agents

After finishing the installation process you need to migrate the package tables to the database. run the following command

php artisan migrate

Basic Usage

Devices

To identify that any specific model could be linked with various devices, you can use the HasMultiAgent trait.

class Client 
{
    use HasMultiAgent;
    ...

To create a new device you can use the register function. Note: uuid should be unique for each device

$device = Device::register('uuid');

Now, you can use the following functions to link/unlink the device with the Client model

use Aldeebhasan\MultiAgents\Models\Device

$device = Device::register('uuid');
$client = new Client();

// Link the device with the model
$client->linkDevices($device);

//you can also pass a list of device objects
$client->linkDevices([$device,$device,....]);

// Unlink the device from the model
$client->unlinkDevices($device);

//you can also pass a list of device objects
$client->unlinkDevices([$device,$device,....]);

//unlink all the devices related to specific model
$client->unlinkAll();

To retrieve all te devices lined to specific model

$client->devices

To obtain the owner of the device use the following.

Note: The owner could be any model use the HasMultiAgent trait, and the device already linked to it.

$device->owner

Finally, thanks for the Agent package author, where you can perform a list of check functions over the current device agent. yYou can check all the function related to the device egent from here.

Now, to retrieve the device agent object you can use.

$device = $client->devices->first();
$device->agent

Middleware

After registering any device, the device object will have a token attribute. This attribute should be sent at the Header or as POSTor GET parameter with the key Device-Token to authenticate this registered device.

To use the device authentication middleware, you need to add it first to the app\Http\Kernel.php under $routeMiddleware as follow:

'auth.device' => \Aldeebhasan\MultiAgents\Middleware\DeviceAuthenticated::class,

Next, you have to attach the middleware to your rout or inside your controller.

//in the routes
Route::middleware(['auth.device'])->group(function () {
    Route::get('/device-info', function () {
        return getCurrentDevice();
    });
});
//in the controller
 public function __construct()
    {
        $this->middleware('auth.device';
    }

The package contains getCurrentDevice() helper function to retrieve the device that match the passed Device-Token

Furthermore, if you want to authenticate only the devices linked with a specific model, you can pass the Model class name to the middleware.

// if the passed token match with any of the token
// registered for the `Client` model it wil allow
// it to pass to the inner route.
// Otherwise, DeviceAuthenticationException Exception will be thrown
Route::middleware(['auth.device:'.Client::class])->group(function () {
    Route::get('/device-info', function () {
        return getCurrentDevice();
    });
});

Exceptions

Two kinds of exceptions could be thrown from the package DeviceAuthenticated middleware:

• DeviceAuthenticationException: when no device match the passed token.
• DeviceExpiredTokenException: when the device token is expired and the device need to be registered again.

Settings

Each device could have a list of setting related to it.

You can initialize a list of settings you want to link with a specific set of devices, and attach them to the devices.

use Aldeebhasan\MultiAgents\Models\Setting

$setting1 = Setting::register('key1');
$setting2 = Setting::register('key2');
//add settings with its value to specific device
$device->addSettings([
            'key1'=>'value1',
            'key2'=>'value2',
        ]);
//remove setting/s from a specific device
//single setting
$device->deleteSettings('key1'); 
//multiple settings
$device->deleteSettings(['key1','key2']); 

//to perform the two operations togather and sync the settings with their value with specific device
$device2->syncSettings([
         'key1'=>'value1',
        ]);
//the sync function will unlink all the settings doesn't much the keys,
// and link/change the  value of the settings that are appeared in the  provided list

Finally, to retrive all the setting related to specific device

$device->getSettings(); 
//output: [
//    'key1'=>'value1',
//    'key2'=>'value2',
//  ]
